Milk fat is separated from proteins by adding sulfuric acid. The separation is facilitated by using amyl alcohol and centrifugation. The fat content is read directly via a special calibrated butyrometer. Gerber developed specialized butyrometers (tubes), pipettes, and centrifuges. Water baths built specifically for the Gerber tubes are often used.
The designations mean that the product contains respectively 75 and 100 kcals per 100 ml. F-75 provides 75 kcal and 0.9 g protein per 100 mL, while F-100 provides 100 kcal and 2.9 g protein. [3] Both are very high in energy, fat, and protein and provide a large amount of nutrients.
Today, most skim milk is created by spinning whole milk in a centrifuge so that the fat droplets separate out. [5] To make low fat milk, one can simply mix skim and whole milk in a fixed ratio. [6] The fat content of the raw milk produced by cows ranges from about 3.3% up to 5%.
To use it in place of fresh milk, simply open a can and mix it with an equal amount of water, then replace the milk in your recipe measure-for-measure. 4. Sweetened Condensed Milk
Sheep and cow milk have a higher casein content than other types of milk with human milk having a particularly low casein content. [2] Casein is the primary emulsifier in milk, that is, it helps in mixing oils, fats, and water in milk. [3] Casein has a wide variety of uses, from being a major component of cheese, to use as a food additive. [4]
This technique is accurate and not affected by fluid contamination, but needs to be performed by trained personnel in a laboratory environment. A hand-held refractometer is the industrial standard used to determine the mix ratio of water-soluble coolants [5] that estimates oil concentration from the sample refractive index measured in the Brix ...
The Reichert value is an indicator of how much volatile fatty acid can be extracted from a particular fat or oil through saponification. It is equal to the number of millilitres of 0.1 normal hydroxide solution necessary for the neutralization of the water-soluble volatile fatty acids distilled and filtered from 5 grams of a given saponified fat.
Benzyl alcohol is a colorless liquid with a mild pleasant aromatic odor. It is useful as a solvent for its polarity, low toxicity, and low vapor pressure. Benzyl alcohol has moderate solubility in water (4 g/100 mL) and is miscible in alcohols and diethyl ether.
