It is rich in SNF content and has high nutritional value and has been utilized in the manufacture of a number of dairy products or in powder form. Buttermilk, a by-product of butter manufacture, has been used as such or in dried form. Ghee residue from ghee manufacture has also found applications in many food products. It contains components derived both from fragments of milk fat globule membrane (MFGM), mainly consisting of proteins and neutral as well as polar lipids and all water-soluble components of cream [24]. Fortification with buttermilk is done to increase the yield provided cheese quality is unchanged.
- IGF-1 is also found in human breast milk and the only hormone known to be absorbed from cow’s milk.
- This causes a higher concentration of solutes on the membrane surface than in the solution, so some of these compounds return to it.

Lassi, also called
chhas or matha, refers to desi buttermilk, which is the by-product obtained when churning
curdled whole milk with crude indigenous devices for the production of desi butter
(makkhan). Lassi contains appreciable amounts of milk proteins and phospholipids. 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. There is a wide range of dairy milk products, including milk of differing fat levels, flavored milk, and more. Definition 1a accurately describes dairy milk products, such as whole milk and buttermilk. Other products sold as “milks” but made from plants like almond, rice, coconut, oat, and hemp “milks” may have calcium.
However, in recent years, sheep’s and goat’s whey proteins have also become an important source of ACE-inhibitory peptides [51]. Other important peptide, lactoferricin, generated by the action of pepsin on lactoferrin has antimicrobial, antifungal, antiviral, antitumor and anti-inflammatory activities [42]. Dullius et al. reviewed the benefits of bioactive whey peptides available for food processing and compared their production processes and development in laboratory conditions as opposed to industrial production [41]. Isolated whey proteins also have uses in the food industry due to their physic-chemical and nutritional properties, which allow them to act as emulsifiers, gelling agents, water binders and foaming/whipping agents in food systems.
One of the best things about cottage cheese is that it is exceptionally protein-dense, especially the lower milkfat variants. Cheese is generally an excellent source of protein, and its fat content will vary depending on the cheese variety. Cheese is a fermented dairy product that comes in different shapes and sizes.
Studies have also demonstrated the CMP protecting effect against acidic erosion of teeth. Therefore, due to its composition SCW can be used for various different purposes including food formulations, nutraceuticals and biofuel products [8,28,34,37,38]. If it has been stored at room temperature for two hours or longer, it is recommended to discard it. 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.

Listeria is most likely to affect pregnant people and newborns, people 65 and older, and those with weakened immune systems, according to the CDC. Infection symptoms typically start within two weeks of eating contaminated food and can include fever, muscle aches, nausea, tiredness, vomiting and diarrhea.
Although these whey proteins are used as additives in the agro-food industry, such as the athletic drinks, still, 40% of whey remains unprocessed, which makes it an interesting resource in view of its excellent oxygen barrier properties [4, 5]. Whey protein films have excellent oxygen, aroma, and oil barrier properties. They have excellent mechanical properties https://personal-accounting.org/ that provide durability when used as coatings on food products, films separating layers of heterogeneous foods, or films formed into pouches for food ingredients. These films do not significantly compromise the desirable primary barrier and mechanical properties as packaging films and hence add value for ultimate commercial applications [6, 7].
Milk composition
Those ingredients were incorporated into the milk, in the proportion of 5% (v/v). The reduced fat cheeses incorporating LWPC, LBM and LSCWC were compared to conventional reduced-fat cheeses and full-fat cheeses. Reduced fat cheeses with 5% incorporation of buttermilk presented the best results, both concerning texture parameters and sensory evaluation. However, the authors indicate that adequate mixtures of such by-products should be tested for similar purposes [75]. Serum Albumin (SA) represents around 6% of bovine whey proteins, has 582 amino acids residues, an MW of 69 kDa and a pI value of around 4.7–4.9. Biological functions of SA include fatty-acid binding and antimutagenic activity.
However, the main cause for the variations in proteins content and state are the factors related to the obtention of cheese whey (sweet or acid) rather than the process of production of the WPC and WPI [63]. Processing conditions, namely thermal treatments, pH and type and quantity of salts present also play a significant role in the functional properties of these products. In the mid-eighteenth century, membrane phenomena were observed and studied, mainly to evaluate barrier properties and related phenomena. The first commercial membranes for practical applications were manufactured by Sartorius in Germany after World War I, the know-how necessary to prepare these membranes originating from the early work of Zsigmondy [84]. The big step in the commercial applications of membrane filtration processes in the dairy industry occurred in the 1960s [34]. Nowadays, membrane processes are used in a wide range of applications and the number of applications is still growing [20,42,84].
U.S. Food and Drug Administration
In this study the authors compared cellulose regenerated acetate, composite fluoro polymer and polysulphone permanently hydrophilic membranes with similar MW cut-off (10 kDa). The results showed better performance for the cellulose regenerated acetate membrane because it had the highest permeate fluxes, the lowest irreversible fouling, good selectivity and the water recovery fluxes was around 100%. The higher hydrophilicity of regenerated cellulose membrane justified these results [28].
Products
The CDC and FDA reopened the investigation in January 2024 after the cheese sample showed that it is the same strain of listeria that caused illnesses in the earlier outbreaks. The CDC reported Tuesday the outbreak has resulted in 26 illnesses with 2 deaths and 23 hospitalizations in 11 states (Arizona, California, Colorado, Florida, Georgia, Nevada, North Carolina, Oregon, Tennessee, Texas and Washington). Some products were also sold at retail deli counters including, but not limited to, El Super, Cardenas Market, Northgate Gonzalez, Superior Groceries, El Rancho, Vallarta, Food City, La Michoacana, and Numero Uno Markets, the company said.
Why is it important to eat or drink dairy?
Generally, whey proteins are highly valued and come in many different forms, such as whey powder (8–12% protein and over 70% lactose), WPC, containing between 30–89% of protein and WPI containing over 90% of protein and almost no lactose (around 3%). Comparison of milk with other by products of milk foods in the diet can affect study results. For example, if comparing milk with high saturated fat meats, milk may show no difference in heart health. However, if dairy fat in milk is compared with unsaturated plant oils, nuts, or seeds, milk may appear to increase CVD risk.
Production of H2O2 and bacteriocins by these organisms prevents proliferation of pathogens. Other products recently recalled for listeria risks include BrightFarms spinach and salad kits and Blue Ridge Beef pet foods. The largest ghee producing states are U.P,
A.P, Punjab, Rajasthan, M.P, Bihar, Hariyana etc. Milk and milk products should be stored in a refrigerator to slow down the growth of micro-organisms, such as mould on cheese.
Cheese
Most milk sold in supermarkets is pasteurized and homogenized, processing techniques that use heat to kill most of the bacteria present and break down fat molecules so that texture of milk remains smooth and creamy. 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.
