Lab Report on milk co-motion. Sample

Lab Report on milk co-motion. Paper When detergent is added to milk and the food color, the non-polar ends of the soap molecules attracts towards the non-polar fat of milk, and the interaction of the detergent with the fat in milk exults the food color to swirl around. Whenever the detergent touches the milk, it breaks up the drops of fat, which spread out, allowing the food coloring and milk to mix. The food coloring swirls into the places where the fat was. Detergent molecules dissolve fat of milk by having one hydrophobic end (which interacts well with the fat) and one hydrophilic end (which interacts well aqueous part of the milk). 2. How would the results of this experiment differ if: a)Skim milk was used? (Milk from which the cream (fat) has been taken is called skimmed milk. ) If skim milk was used, the drops of food color would dispersed in milk without the need of detergent because all the fats has been taken out of milk and it allows the food color to dissolve in it. )Homogenates milk was used? (Homogenates milk is the milk in which all the fat are mixed so that it does not rise on the top) Fat is insoluble in water. Water-soluble food colors will spread and dissolve in water, but their motion would be slow if homogenates milk was used, because milk contains globules of fat, the fat that is mixed in. The swirling and churning motion would be partly due to the attraction between soap and the milks fat articles. 3. Research emulsi fying agents and how they are used in the food in the food industry?

Substances that are soluble in both fat and water and enable fat to be uniformly dispersed in water are emulsifiers. Emulsifying agents used in foods include agar, albumin, alginates, casein, egg yolk, glycerol monasteries, gums, Irish moss, lecithin, soaps. Emulsifying agents work by reducing surface tension, forming complex films on the surface of emulsified droplets and creating repulsive barrier on emulsified droplets to prevent their coalescence. . What is an emulsifying agent in the body? Explain how it works? Emulsifying agent in the body: The emulsifying agent in the human body is bile. It is a bitter, alkaline, brownish- yellow or greenish-yellow fluid that is secreted by the liver, stored in the gallbladder, and discharged into the duodenum. Bile contains bile acids, which are critical for digestion and absorption of fats and fat-soluble vitamins in the small intestine. Many waste products are eliminated from the body by secretion into bile and elimination in feces.
