Wheat flour (Figure 1A) is the product obtained by grinding whole wheat kernels, sometimes called berries (Figure 1B). A grain of wheat consists of three parts – bran, germ and endosperm (Figure 2). During the milling process, these three parts are separated and combined to create different flours. For example, white flour includes the finely ground endosperm, while whole wheat flour contains all three fillings. Other popular flours include all-purpose flour, bread, sponge cake, self-rising flour, pastry, semolina, thickener, and gluten flour.
There are six varieties of wheat grown in the United States, including: Red Winter Hard, Spring Hard Red, Winter Soft Red, Soft White, Hard White, and Durum. These grades have distinct characteristics, especially protein and gluten content, and are used to make different foods. Durum wheat flour has a higher protein content and is often used to make bread. Soft flour is used for cakes, pastries, cookies, crackers and Asian noodles. Durum wheat flour is used in pasta. All-purpose flour is ground from a mixture of hard and soft flours, making it suitable for making a wide variety of products.
Flour can be enriched, that is to say transformed; Wheat flour is fortified with nutrients equal to or greater than those found in unprocessed flour, including iron and B vitamins (thiamin, niacin, riboflavin and folic acid). Wheat flour can also be bleached (chemically) to whiten or improve baking quality or unbleached (naturally aged and bleached with oxygen in the air).
When mixing flour with water, the proteins of the dough; gliadin and glutenin combine to form a protein known as gluten. Gluten gives dough elasticity, strength and structure. People with celiac disease, certain neurological conditions, certain skin conditions, or gluten sensitivity due to other causes often benefit from a gluten-free diet.
Although usually derived from wheat, flour can also be ground from almonds, amaranth, barley, buckwheat, chickpeas, coconut, corn, millet, oats, quinoa, rice, rye, sorghum, soy, tapioca and teff.
By-products of wheat milling, such as bran, “shorts” (the inner layer of the wheat grain husk which contains starch or flour components) and “young flesh” (the resulting ) bran and short), used in animal production. to feed.
Foodborne outbreaks and recalls
Flour-related food outbreaks have been linked toSalmonella, Production of Shiga toxinsEscherichia coli(STEC) and ready-to-use poisons or other short-acting substances. Wheat flour was not a food of great concern until recently due to illnesses associated with eating raw flour or products containing raw flour, such as raw cookie dough or baking mixes. . Between 2000 and 2020, at least 6 flour-related outbreaks were reported to the CDC’s National Disease Reporting System (NORS), resulting in 106 cases of illness, 23 hospitalizations, and no deaths.
Between 1961 and 1985 and 1987, outbreaks involving contaminated grain products occurred in China and India, respectively. About 35 outbreaks have caused 7,818 cases in China and a single outbreak has caused 97 cases in India. Testing of corn and wheat samples from China and related wheat products from India revealed elevated levels of the mycotoxin deoxynivalenol (DON).
Between 1997 and 1998, there were 16 outbreaks involving burritos served primarily in schools in seven states. Due to the symptoms and the short incubation period, a preformed toxin, such as DON or another short-acting agent, is suspected to be the cause. There are around 1,900 cases, of which 1,700 are children. Because burrito fillings vary by outbreak site, flour-based corn tortillas are suspected to contain the causative agent. Burrito sample testing detected DON within the FDA acceptable level of 1 ppm for finished wheat products. Burritos made by both manufacturers were implicated, and all related products were recalled or discontinued. A similar phenomenon occurred between 2003 and 2004, during which 10 outbreaks involving flour bread from a single manufacturer occurred in schools in Massachusetts. An FDA inspection of the factory revealed improper storage, use and labeling of chemicals, improper storage of food ingredients and additives in unlabeled containers, unprotected food contact surfaces and lack of sewage system backflow protection. Product testing has shown high levels of calcium propionate and potassium bromate, which can cause gastrointestinal illness when consumed in large amounts, especially in children.
In 2005, there was an epidemicSalmonella entericaTyphimurium serotype linked to cake batter served at Cold Stone Creamery locations in the United States. There are 26 cases, 5 hospitalizations and 0 deaths linked to this epidemic. The ice cream contained a raw cake mix, which was found to be contaminated with the outbreak strain of the virus. Cold Stone Creamery has voluntarily removed all baking powder products from its stores. Cake mix ingredients include egg whites and flour, both of which may be contaminatedSalmonella, plus additional low-risk components.
In 2008, the explosion ofSalmonella entericTyphimurium serotype combined with raw wheat flour has caused 67 cases, 12 hospitalizations and 0 deaths in New Zealand. During this epidemic, raw flour was often consumed in the form of uncooked homemade baking mixes, such as muffins or pancakes. The outbreak strain was isolated in both unopened and opened products from the homes of sick people. All affected flour lots have been voluntarily recalled by the factory and a statement advising against the consumption of uncooked flour has been added to product labels. In keeping with good manufacturing practice, a dry cleaning vacuum has also been installed at the factory to better remove dirt from incoming seeds. Two weeks prior to this outbreak, there had been an outbreak related to poultry feed. Traceability efforts revealed that the relevant live bird feed ingredient was produced in the same grain mill that produced the contaminated flour intended for human consumption.
In 2009, wheat flour was the suspected cause of an outbreak of STEC O157:H7 associated with the consumption of raw cookie dough prepackaged by Nestlè Toll House. There are 77 cases linked to this outbreak, with 35 hospitalizations and no deaths in 30 states. Ten cases developed hemolytic uremic syndrome (HUS). FDA testing of the finished product shows an epidemic strain. Production has been temporarily halted and all Nestlè Toll House biscuit flour products are subject to a voluntary recall. Following this outbreak, Nestlè switched to using heat-treated wheat flour in the production of cookie dough and changed its product labels to display warnings against raw flour consumption more prominently. Although wheat flour has not been definitively identified as the contaminated cookie dough ingredient, it is considered the primary suspect for the source of this outbreak.
In 2016, an outbreak linked to General Mills flour sickened 63 people in 24 states with STEC O121 and O26. There were 17 hospitalizations, no deaths and 1 case of HUS. The outbreak strain was isolated from open products from the homes of sick people. General Mills has voluntarily recalled flour sold under the Gold Medal, Gold Medal and Signature Kitchens brands. Other products containing General Mills flour, such as bakery mixes and prepackaged breads sold under various brand names, are also being recalled.
In 2019, an ongoing outbreak of STEC O26 linked to wheat flour from ADM Milling Co. The outbreak strain was isolated from the unopened product. Flour manufactured by ADM Milling Co. The affected products have been voluntarily recalled.
One of the most recent flour-related recalls occurred in 2021 forSalmonellaPollution. New York-based Tiger Nuts Inc. recalled all packaged, disease-free flours.
These outbreaks suggest that wheat flour can be a source of contamination and illness when eaten raw.

In the United States, wheat is grown in 42 states and is the third largest crop in terms of area, production and value, after corn and soybeans. During the 2018/2019 season, US farmers produced an estimated 1.884 billion bushels of wheat from 47.8 million acres of cropland. Wheat production peaked in the United States in 1981, but has since declined by more than 30 million acres and 900 million bushels. Foreign competition, changes to US farm laws and changing consumer preferences have all contributed to this decline. In 2008, the top wheat producing states (in order of yield) in the United States were Kansas, North Dakota, Washington, Montana and Oklahoma. Nearly half of US wheat production is exported.
The United States classifies wheat varieties as “winter” or “spring”, depending on the season in which they are grown. Winter wheat is sown in the fall and matures before going into winter dormancy. The following spring, the winter wheat continues to grow until the summer harvest. Winter wheat accounts for 70-80% of total wheat production in the United States and has higher yield potential than spring wheat due to the longer growing season. Spring wheat is sown in the spring and harvested in late summer or fall of the same year. Spring wheat is primarily grown in the Northern Great Plains region, where freezing winter temperatures can kill winter wheat during dormancy. Yield potential in this region is low due to suboptimal moisture and higher growing season temperatures, causing wheat plants to mature faster. Irrigation and fertilization increase crop yield potential, while drought conditions and freezing spring temperatures can reduce yield potential.
Specific gravity: the weight of a specific volume of grain; provides an index of grain quality and an estimate of flour yield
Cereal protein: the concentration of protein in the grain; higher protein powders have higher water absorption and harder, easier to stretch dough characteristics
Falling number: a measure of the enzymatic activity of the seed; Enzyme activity in dough is needed to convert starch into sugar for yeast
Deoxynivalenol (DON) content: the level of DON toxin present in the seeds; Acceptable levels in the finished product for humans are <1ppm
Moisture: a measure of the moisture content of the dough; Higher humidity is conducive to the growth of mold, bacteria and insects
Ash Content: A measure of the mineral (ash) content of flour or wheat; gives an indication of the yield to be expected when grinding, since the ash is mainly concentrated in the bran
On arrival at the mill, the wheat is cleaned to remove coarse impurities and preserved according to its quality.
The wheat is then cleaned further by sifting, removing coarse and fine matter and separating the kernels by size, shape and weight. The whole wheat is transferred to the compost bin.
Conditioning takes place before milling to produce uniform moisture throughout the grain. This helps prevent bran breakage during grinding and improves endosperm separation.
After conditioning, different batches of wheat are mixed (milled) together to create a mixture capable of producing the desired quality of flour.
Milling is the separation of the bran and germ from the endosperm and the reduction of the endosperm to a uniform grain (powder) size. Crushing is carried out by a sequence of crushing, grinding and separation operations.
The quality of the wheat determines the type of flour(s) produced. Different flours produced in a factory can be combined to create different variations. Whole grain flour contains all parts of the kernel, including the bran, germ, and endosperm. Brown flour also has all the parts, but with some germ and bran removed. White flour contains only the endosperm of the filling.

Until recently, foods with low moisture content such as flour did not pose a food safety concern. However, wheat flour is generally considered a raw agricultural product that is not ready-to-eat or pasteurized. There are also opportunities for contamination throughout the continuous farm-to-fork process when grain is turned into flour. While killing food preparation and processing steps (such as boiling, baking, roasting, microwaving, or frying) eliminate foodborne pathogens that may be present in raw flour , the consumption of products containing raw flour that has not undergone the killing stage is associated with epidemics. Related products include prepackaged raw cookie dough, prepackaged baking mixes, homemade raw dough and dough, homemade whipped cream, and modeling clay. The risk of cross-contamination also exists when utensils or containers come into contact with raw flour used with cooked or ready-to-eat products.
When it burstSalmonellaWith regard to dough, raw or undercooked eggs may be considered the most likely source of contamination, but flour has recently emerged as a vector of infection and should be investigated. A 2007 study reportedSalmonellain 0.14% of wheat flour samples in the United States, but previous studies have reported levelsSalmonellaas 1.34% andE-coliis 12.5%. Additionally, grains are often not treated to kill microbial pathogens before being ground, so any contamination that occurs in the field can be transferred to the final product.
A study demonstrated the ability toE-coliO157:H7 persists on flowering wheat ears for at least 15 days and enters wheat plants through contaminated seeds, soil and irrigation water, with internalization rates of 2.5 and 10 %, respectively. . Wheat fields near cattle ranches are potentially polluting due to heavy rainfall or contaminated irrigation water. Various studies have proven thatE-colican survive 2 months, 6 months or up to 500 days in soil, depending on temperature.
The powder should be stored in a cool, dry place in an airtight container. All-purpose flour, bread and muffins will keep for 6 months to 1 year if stored at 70°F and 2 years if stored at 40°F. Flour should be stored in the refrigerator or frozen , if possible. The natural oils found in flour, especially whole wheat flour, oxidize when exposed to air, especially at room temperature, and cause the flour to go rancid.
Food safety programs in the milling industry designed to reduce and prevent the risk of microbial and mycotoxin contamination include hazard analysis.
Deoxynivalenol (DON) is a mycotoxin produced byFusariumFungal species commonly infect grains, such as corn, wheat, oats and barley, in the field or during storage. DON is also known as emesis toxin due to its strong emetic effect after consumption. DON is associated withFusariumPowdery mildew, also known as scab, is a disease of wheat and barley that results in reduced yield, low weight, poor seed germination, and contamination of seeds with mycotoxins. There is a limit of 1 ppm set by the United States Food and Drug Administration for DON in all finished wheat products intended for human consumption. Mycotoxins, including DON, are very stable, able to withstand high temperatures, and their content in cereals will not change even after many years of storage. DON has been detected in buckwheat, popcorn, sorgum, triticale, flour, bread, breakfast cereals, noodles, baby food, pancakes, malt and beer.
The best method for dealing with DON contamination in flour is to prevent contaminated grains from entering the milling process. Screening incoming wheat, using rapid tests such as ELISA kits, allows millers to weed out supplies that exceed safe levels of DON. Grains contaminated with DON can also be removed during cleaning using gravity tables and optical sorters, but this process concentrates DON in the screening of wheat, preventing its use in livestock feed.
Flour is a low-moisture food with a water activity (Aw) of 0.87 or less. In general, an Aw of 0.95 or greater is required to support microbial growth. The primary concern for wheat flour is the microbial contamination that can be carried during the milling process, which exists in processed flour, and the potential for foodborne illness when the flour is incorporated into food products.
One method that has been shown to be effective in removing microbial contamination is the vigorous brushing or abrading, also known as cleaning or peeling, of the wheat to remove the outer bran layer during the conditioning program. This process requires a lot of energy and the sound removal rate is difficult to control. Also, it is not possible to completely eliminate core sound. Denaturation also leads to microbial contamination of the rejected sound.
Another method to control microbial contamination of wheat is to incubate the water with ozone or chlorine. Chlorination is cheaper and more effective than ozone but can leave residues.
Processing the end product, flour, is more expensive than processing grain. Effective methods include gamma ray irradiation and heat treatment. However, gamma irradiation has been shown to have a negative impact on pulp quality. Similarly, if not done properly, heat treatment can also negatively impact dough quality and cause browning.
Per capita wheat flour use in the United States tended to increase from the 1970s through the late 1990s, but fell sharply in 2000 due to changing consumer preferences; Most notable is the growing interest in low carb diets. In 2014, the estimated per capita use of wheat flour was 135 pounds per person.
US consumption of wheat products (such as bread, pasta and pizza) has fallen sharply since 2000, reversing a three-decade trend of per capita consumption growth. Wheat consumption fell from about 146.3 pounds per person in 2000 to a low of 133.4 pounds in the mid-2000s, recovering slightly, and then fell back to 132.5 pounds per person in 2011. The decline since 2000 may reflect public interest in reducing carbohydrate intake. . The increase in wheat consumption that began about 30 years ago was also triggered by health issues. In the 1970s, Americans began switching from animal products to whole grain foods, including wheat products, due to concerns about cholesterol and heart disease.
This change was later reversed when gluten became increasingly looked down upon by the public in the 2000s, where some evidence suggested that gluten was linked to schizophrenia, autism, chronic inflammation and schizophrenia, the diabetes and other diseases. These claims are associated with the rise of gluten-free diets among non-celiac or non-celiac gluten-sensitive individuals and the concurrent rise of the gluten-free food and drink industry in the early 1990s. 2010. Accordingly , a wide variety of gluten-free products are available to replace wheat and gluten-containing products, including breads, cereals, pizzas, noodles and snacks.
Despite the reduction in consumers’ consumption of products containing flour, outbreaks have become more frequent in recent years. To reduce the risk of foodborne illnesses, we do not recommend consuming products containing raw flours, such as flours or pasta. Consumers are also reminded to wash their hands, work surfaces and utensils thoroughly after coming into contact with powdered or powdered products.

Wheat flour contains fiber, B vitamins (thiamin, riboflavin, niacin and folate), calcium, iron, magnesium, phosphorus, potassium and zinc and is also a good source of complex carbohydrates. The bran component of the wheat grain contains fiber, the endosperm contains protein, carbohydrates, and small amounts of B vitamins, and the germ contains trace minerals, unsaturated fats, B vitamins, antioxidants, and antioxidants. other plant nutrients. Fiber helps lower blood cholesterol, lower your risk of heart disease and type 2 diabetes, and support bowel function. B vitamins are important for metabolism and a healthy nervous system. Folate (folic acid) helps form red blood cells. It is important that women of childbearing age who can become pregnant consume adequate amounts of folic acid to reduce the risk of neural tube defects such as spina bifida and anencephaly during fetal development. Iron is needed to transport oxygen in the blood, and too little iron can lead to iron deficiency anemia.
Food products made from wheat grains can be classified as whole grains or refined grains. Whole grain products contain the entire wheat grain, including the bran, germ and endosperm, while refined grain products contain only the endosperm. Refined grain products generally have a smoother texture and longer shelf life, but contain less fibre, iron and B vitamins than whole grain products. Many refined grain products, such as white flour, are fortified with B vitamins (thiamin, riboflavin, niacin, and folic acid) and iron, which means the nutrients are returned to the finished processed product in amounts equal to or greater than those present in the unprocessed product. Similarly, grain products can also be fortified with folic acid or calcium, which means that the nutritional status of the product is higher than that of the unprocessed product. Blanching does not affect the nutritional value of the powder.
For a 2,000-calorie diet, the Dietary Guidelines for Americans 2015-2020, the American model for healthy eating, recommends consuming 6 ounces of grain equivalents per day, of which 3 ounces and above are whole grains.
The Whole Grain Stamp (Figure 4), created by the Whole Grains Council, is an image that appears on food labels to help consumers identify products that contain half or some whole grain in each serving. The “good source” contains a half serving of whole grains with at least 8 g of whole grains per serving. “Great Source” contains one serving of whole, whole grains with at least 16g of whole grains per serving. “100% Great Source” contains one serving of whole grains with at least 16g of whole grains per serving and no refined grains.
