Lesson 4

Determining the naturalness of milk by organoleptic

and physical and chemical parameters. Determination of sanitary and hygienic indicators and type of milk in accordance And

with GOST requirements for purchased milk.

Determination of mastitis milk, establishment of milk pasteurization,

detection of inhibitory and other foreign substances in milk

(Test)

    Control of milk naturalness

Milk is considered adulterated if foreign substances have been added to it or fat has been removed.

Distinguish character falsification, i.e. what is added to the milk (water or skim milk or both water and skim milk - double adulteration) and degree adulteration - the amount of added substances (water, skim milk) as a percentage.

To determine the nature and degree of falsification of milk, it is necessary to know the content of fat, dry matter, SOMO, and the density of milk in the test and stall samples.

1) adulteration with water. When water is added to milk, the content of dry matter, SOMO, fat, as well as density and acidity decreases. The degree of falsification is calculated using the formula:

B = [(SOMO - SOMO 1) / SOMO] x 100,

where B is the amount of water added to milk,%;

SOMO - stall sample indicator, %;

SOMO 1 - indicator of the test sample.

2) adulteration of milk with skim milk or skimming. When adding skim milk or skimming the cream, the density increases, the dry matter and fat content decreases, and the SOMO does not change or slightly increases.

The degree of falsification is calculated using the formula:

O = [(F - F 1) / F] x 100,

where O is the amount of added skim milk, %;

For greater reliability, when establishing the nature of falsification in the case of adding skim milk, a calculation is made using the formula:

W St = (W 1 / C 1) x 100,

where F st is the fat content in milk dry matter, %;

The presence of less than 25% fat in the milk solids indicates that skim milk or skimmed milk has been added to it.

3) double falsification. When water and skim milk are simultaneously added to milk, the content of dry matter, SOMO and fat decreases, and the density does not change or changes slightly depending on the ratio of the added components. The degree of falsification is determined by the formulas:

D = 100 - [(F 1 / F) x 100] ;

B = 100 - [(SOMO 1 /SOMO) x 100] ;

where D is the total amount of water and skim milk,%;

B is the percentage of added water;

O - percentage of added skim milk.
