Lactose, All you need to know ! !😵

Facts known to us           :

  • Lactose is a disaccharide that yields D-glucose and D-galactose on hydrolysis.
  • Lactose is one-sixth times sweeter than sucrose
Facts we need to know   :

 It is designated as 4-ortho-β-D-galactopyranosyl-D-glucopyranose.

  Î±-lactose: Ordinary commercial lactose is α-lactose monohydrate.

  •  It is prepared by concentrating an aqueouslactose solution to super saturation and allow for crystallization to take place at a modern rate below 93.5 0C. 
 Î²-lactose: This is the other isomeric form lactose. 

  • It exhibits a specific rotation of +35.00on anhydrous weight basis. Above 93.50C crystallization or drying of lactose solutions yields β anhydrate.

Milk from crops???? What is Crop milk?

Will there be no need of Cow in future??????? A known fact is that -  Crop milk contains more fat and protein content as compared to human or cow milk. But  What is this Crop milk?

Vitamins in MILK

Vitamins are organic substances which occur in very small concentrations in both plants and animals. They are essential to normal life processes. The chemical composition of vitamins is usually very complex, but that of most vitamins is now known. The various vitamins are designated by capital let- ters, sometimes followed by numerical subscripts, e.g. A, B1 and B2.  Milk contains many vitamins.  Among the best known are A, B1, B2, C and D. Vitamins A and D are soluble in fat, or fat solvents, while the others are soluble in water. Lack of vitamins can result in defi- ciency diseases

Why does Mozzarella Cheese stretch?????

Mozzarella cheese was originally manufactured from high fat Buffalo m ilk in Italy, but it is now made all over Italy, in all European countries and USA from  Cow milk It belongs to the cheese classified as 'Pasta- filata' which involves the principle of skillfully stretching the curd in hot water to get a smooth texture and grains in cheese. It is a soft, white, unripened cheese which may be consumed shortly after its manufacture. Its melting and stretching characteristics are highly appreciated in the manufacture of PIZZA, where it is a key ingredient. Shelf life of this cheese is at most 2 weeks. This cheese gives good gritting/ shredding quality.  Milling acidity for Mozzarella cheese is about 0.7%L.A. . Stretching in this cheese is because the di calcium para-caseinate breaks into mono calcium para-caseinate, and this happens because the ph is brought at about 5.6 . It is made either by traditional method or by Direct acid coagulation.
