According to a 2009 review by the American Heart Association, instead of avoiding ω-6 fats, the ω-6:ω-3 ratio should be decreased by consuming more ω-3 fats. The conversion rate of linoleic acid (LA) into arachidonic acid is very low with a diet high in linolenic acid. [11] The maximum ω-6:ω-3 ratio allowed in dog food by the AAFCO is 30: ...
[1] [2] [3] It is a measure of the average molecular weight (or chain length) of all the fatty acids present in the sample in form of triglycerides. The higher the saponification value, the lower the fatty acids average length, the lighter the mean molecular weight of triglycerides and vice versa.
Thus, the higher the iodine value, the more unsaturations are present in the fat. [1] It can be seen from the table that coconut oil is very saturated, which means it is good for making soap . On the other hand, linseed oil is highly unsaturated , which makes it a drying oil , well suited for making oil paints .
HLB scale showing classification of surfactant function. The hydrophilic–lipophilic balance (HLB) of a surfactant is a measure of its degree of hydrophilicity or lipophilicity, determined by calculating percentages of molecular weights for the hydrophilic and lipophilic portions of the surfactant molecule, as described by Griffin in 1949 [1] [2] and 1954.

This included 1% milk, meaning varieties with 1% butterfat content could not be labelled as milk. Lobbying by Britain has allowed these other percentages to be sold as milk. [22] After the change in regulation, all major supermarkets have launched a 1% variety, but production has largely ceased since the COVID-19 pandemic. [citation needed]
Sherbet contains 1–2% fat; Lowfat ice cream, also called ice milk, contains no more than 2.6% fat; Ice cream contains at least 10% fat; Frozen custard, like ice cream, contains at least 10% fat, but it also must contain at least 1.4% egg yolk solids; Creams. Half and half contains 10.5–18% fat; Light cream and sour cream contain 18–30% fat

A combination of water-soluble and fat-soluble antioxidants is ideal, usually in the ratio of fat to water. In addition, rancidification can be decreased by storing fats and oils in a cool, dark place with little exposure to oxygen or free radicals, since heat and light accelerate the rate of reaction of fats with oxygen.
