Dairy product Definition, Types, Nutritional Content, & Production

The dairy and wider food sector processes raw milk into a vast array of products including cheese, butter, yoghurt, cream, condensed milk, and dehydrated milk. The dairy sector also produces various https://personal-accounting.org/milk-by-products-utilization/ byproducts including buttermilk, whey, ghee, and skim milk. These dairy byproducts have high nutritional value and have applications in many food industries as well as non-food applications.

  • Caseins has been used directly in food industry not as by-product, but as an ingredient.
  • Flavor intensity was not affected by the addition of whey proteins [11].
  • This trend is pronounced in East and Southeast Asia, particularly in highly populated countries such as China, Indonesia and Viet Nam.
  • The production of dairy foods places considerable demand on land, water, and other natural resources, and dairy-producing ruminant animals like cattle, sheep, and goats generate methane—a powerful greenhouse gas.

Although pasteurization kills much of the bacteria in milk, any remaining bacteria can grow quickly in milk at room temperature or warmer. Once milk is opened, it will last about 3-5 days after the sell-by date on the label. Spoiled milk has a strong, sour odor and lumpy texture caused by excess bacteria producing lactic acid, which curdles the protein in milk and produces off odors.

Technology behind cheese making

Its texture is quite a bit more pliable and chewy than the other brands, tearing the way real cheese slices do when you pull them apart. The flavor of this cheese is the most nuanced, even if it is mild, having a complexity that mimics actual dairy. It also melts quite well, meaning you can eat it as-is or in any recipe. While the cheese had a relatively convincing cheddar aroma and appeared to have a decent texture when I first cut into it, I quickly lost interest when I took a bite. The texture ended up being somewhat plasticky, and the flavor was purely that of almond. This cheese is neither vegan nor suitable for those with a dairy allergy.

  • Α-Lactalbumin binds metal cations with a high affinity to calcium and several other ions.
  • Observational studies demonstrate that dairy intake may protect bone health and help prevent fractures (6, 7).
  • This protein density makes it an excellent option for anyone looking to increase their protein intake.
  • Many observational studies have looked at the association between milk and cancer risk.
  • Therefore, it needs to be quickly cooled down after heating to keep any surviving bacteria from multiplying.

The fat globules are smaller and therefore remain suspended, so the cream does not rise and mechanical homogenization is unnecessary. Goat milk curd forms into small, light flakes and is more easily digested, much like the curd formed from human milk. It is often prescribed for persons who are allergic to the proteins in cow’s milk and for some patients afflicted with stomach ulcers.

Table of contents

Dairy product, milk and any of the foods made from milk, including butter, cheese, ice cream, yogurt, and condensed and dried milk. For the deproteinized milk, the hydrophilic antioxidant compounds (vitamin C and uric acid) were highlighted as the constitutes responsible for antioxidant properties. Significant differences in total antioxidant properties were found between whey and deproteinized milk. Codex Alimentarius defines a milk product as a “product obtained by any processing of milk, which may contain food additives, and other ingredients functionally necessary for the processing”. Still, some people are allergic to milk proteins or intolerant to milk sugar (lactose).

Dairy By-Products: A Review on the Valorization of Whey and Second Cheese Whey

Rival, Fornaroli, Boeriu, and Wichers, (2001) have shown that caseins and casein-derived peptides had lipoxygenase-inhibitory properties, as well as enzymatic and non-enzymatic lipid peroxidation inhibitory properties [11]. At the end of the day, moderate consumption of cow’s milk is healthy for most people — but you should avoid drinking it in excess. An exception is cheese, which is usually produced from unhomogenized milk. However, a fair number of studies indicate that dairy consumption may increase the risk of prostate cancer in men (42, 43). As a public health strategy, fortifying milk products with vitamin D is common and even mandatory in some countries (17).

Food Storage

The amount of ghee residue was found to depend upon the method of preparation of ghee. This was due to the variation of nonfatty serum constituents of the different raw materials used for the preparation of ghee. Ghee yield was higher from creamery butter method in comparison to direct cream method, whereas ghee residue content was higher in direct cream method in comparison to creamery butter method. The average yield of ghee residue was maximum (12%) in direct creamery (DC) method followed by almost the same yield in creamery butter (CB) and desi butter (DB) methods, that is, 3.7%.

Whole milk contains saturated fat, which is known to increase total cholesterol, raising both LDL “bad” and HDL “good” cholesterol levels. However, the minerals in milk, specifically calcium and potassium may help to control blood pressure. Milk consists of water, carbohydrate (in the form of lactose, a type of natural sugar), fat (unless non-fat), vitamins, minerals and protein. In recent years there
has been wide spread and increasing interest through out the world in creating newer
channels of utilization for the by-products of the dairy industry. Conversion of edible
substances into non-food items is not ordinarily justifiable especially in countries where
there is an overall shortage of milk supplies. It has always been realized that economic
disposal of by-products is an essential perquisite to profitable dairying.

When acid is used to coagulate milk at its isoelectric pH, the washed and dried curd that results is known as acid casein. Acid casein may be further processed by solubilisation using alkali e.g. Caseins has been used directly in food industry not as by-product, but as an ingredient. However, in some dairy processes a surplus can exist, being recovered as a potential co-product.

Its name combines the words “dairy” and “Dāya,” which means mercy, kindness, and compassion in Sanskrit. All its cheeses are gluten-free, dairy-free, nut-free, vegan, and non-GMO. As an individual who is a part of that percentage of people diagnosed with cow’s milk sensitivity, I have slowly been converting my cheese consumption habits to incorporate more plant-based varieties.
