Next, the arrow on the sliding portion is placed against the fat content of the given milk and bottom part of scale would give the percentage of total solids opposite to the CLR reading on small scale. This would give the corrected lactometer reading. The corrected lactometer is observed opposite the line indicating observed temperature of milk. The observed lactometer reading is placed opposite the little arrow at 60 0 F on the temperature scale. The total solids can be determined if lactometer reading, temperature of milk and fat content is known. The mechanical device made in the form of a ruler with a sliding centre slip. Chemical Properties of Milk - Composition of Milk Several factors influence Age and health of the animal Breed of animal Seasonal changes Weather Nature and quality of feed Stage of lactation, etc. In order to design the milk protein composition to meet dairy processing requirements, selection for genetic variants of milk proteins have been proposed. To have immediate results the total solids content is determined by Richmond’s scale. Iii) Place the figures of fat and CLR in the following formula for calculating total solids and solids not fat. Ii) Take out the lactometer reading and temperature of milk and calculate. I) Determine the fat percentage of milk sample by Gerber’s method. Causes of variation in the composition of milk. The total solids are determined by formula. Lactation, the production of milk by the mammary gland, is a distinguishing characteristic of mammals. This process should be continued/repeated till getting the constant weight or difference in last two weights should not exceed 0.01 gm. Remove the crucible from oven and cooled in desiccators’ and weigh. Again put the crucible for ½ hour in oven. Remove the crucible from oven and cool in desiccators’ and weight. Remove this presentation Flag as Inappropriate I Dont Like This I like this Remember as a Favorite. Put the crucible in hot air oven adjusted at 100 0 C for 3 to 4 hours. FACTORS AFFECTING COMPOSITION AND QUALITY OF GOAT MILK - PowerPoint PPT Presentation. Clean and dry in hot air oven for 1 ½ hour. Take flat bottomed 50 cm diameter porcelain crucible. Chemical Composition and Chemical Standards for Raw Milk 2.5. This is an accurate method but not practicable and hence is not used.
