What is rancidity and what are its types?
Rancidity is the development of unpleasant flavors and odors in fats and oils as a result of chemical changes. There are two main types of rancidity: oxidative rancidity, which occurs when fats and oils react with oxygen, and hydrolytic rancidity, which occurs when fats and oils react with water.
What are fats and oils two types of?
Fats and oils are two types of lipids. Lipids are organic compounds that are insoluble in water and play various roles in the body, such as providing energy, insulating organs, and serving as structural components of cell membranes.
What are the 3 substances that water cannot dissolve?
Solid in a gas (smoke, smog), Gas in a gas (the atmosphere), a solid in a solid, a gas in a solid, etc.Gas in a gas (the atmosphere), Solid in a gas (smoke, smog), a solid in a solid, a gas in a solid, etc.
What are two properties of glycerides?
Glycerides are esters composed of glycerol and fatty acids, commonly found in fats and oils. They serve as a major source of energy storage in the body and play a role in biological membranes.
What two substances are mixing togetherwith food in the duodenum?
Bile from the gallbladder and pancreatic enzymes are mixing with food in the duodenum. Bile helps emulsify fats, making them easier to digest, while pancreatic enzymes help break down carbohydrates, proteins, and fats in the food.
Which two oils are classified as saturated fats because they lack double bonds?
ginkgo and kinfolk oils

palm oil and peanut oil
Are fats acidic?
"Fatty Acids" take on two 'forms' - 'fats' are from animal sources and are solid at room temperature whereas 'oils' are from plant sources and are liquid at room temperature.
What are two compounds of soap?
Oils and fats for soap are compounds of glycerin and a fatty acid. When oils are mixed with an alkali, they form glycerin and the sodium salt of the fatty acid. The fatty acids required for soap making are supplied by tallow, grease, fish oils, and vegetable oils. The hardness, lathering qualities, and transparency of soap vary according to the combinations of fats and alkalis used as ingredients. An experienced soap crafter uses many combinations of oils.

What is the role of an emulsifier in blending essential oils with water?
An emulsifier helps essential oils mix evenly with water by reducing the surface tension between the two substances. This allows the oils to disperse throughout the water, creating a stable blend.
How you check rancidity?
we can check rancidity thru two methods :- check the smell usually it becomes foul and see if the the fats and oils are oxidized ,if yes then it is rancidity.
Which two types of substances are needed in a humans diet for energy?
Carbohydrates and fats are the two types of substances needed in a human diet for energy. Carbohydrates are the body's main source of energy, providing quick fuel for muscles and the brain. Fats are also important for energy storage and providing a slower, long-lasting source of energy.

Why fats remain solids at room temperature while oils are liquids at room temperature?
Because that's the definition of "fat" as opposed to "oil". Fats are solid at room temperature, oils are liquid at room temperature. Chemically they're very simliar compounds, but fats tend to have saturated long chain fatty acids, while the fatty acids in oils are either short chains or unsaturated.
What are some food examples of lipids?
Some examples of lipids in food include oils (such as olive oil, avocado oil, and coconut oil), butter, ghee, fatty fish (like salmon and mackerel), nuts and seeds, and fatty cuts of meat. Lipids play essential roles in our diet by providing energy, aiding in absorption of fat-soluble vitamins, and contributing to cell structure.
