[00:00.48]The chemical properties of fat include
[00:03.09]Its hydrolysis and its saponification
[00:05.76]Triglycerides react with water
[00:08.10]Produce glycerol and fatty acids
[00:10.83]Chemical properties of fat
[00:13.08]Perorated by reaction
[00:14.19]Not only hydrolysis and saponification
[00:15.93]And hydrogenation and iodination
[00:21.33]The saponification of fat is
[00:23.58]Triglyceride and potassium hydroxide
[00:26.34]They react with each other
[00:28.23]Glycerol and fatty acid salts are produced
[00:31.08]If an excavator is used as a metaphor
[00:34.44]Hydrolysis can be interpreted as
[00:36.78]Use the bucket to break down a stone
[00:39.66]Break down into pieces and sand
[00:42.12]As for the saponification reaction
[00:44.64]Replace the bucket with a breaking hammer
[00:47.04]Corresponding to efficient decomposition of fat molecules
[00:51.51]What is obtained is a plurality of pieces and powder
[01:22.59]Hydrogenation and iodination of fats
[01:24.09]The reactants are unsaturated
[01:27.30]But also contain carbon-carbon double bonds
[01:30.03]Add hydrogen or halogen
[01:32.46]In addition under the action of catalyst
[01:34.86]In order to analyze the unsaturation of fatty acids
[01:38.01]Put the grams of iodine consumed in the reaction
[01:43.20]Collectively referred to as iodine value
[01:44.61]Definition of saponification value
[01:45.54]In the range of one gram of fat
[01:47.73]At the time of complete saponification
[01:50.13]The number of milligrams of potassium hydroxide
[01:52.89]The greater the saponification value
[01:55.02]The smaller the molecular weight of fatty acids
[01:57.93]Equivalent to the speed at which an excavator breaks rocks
[02:00.81]Is inversely proportional to the energy required
[02:05.07]If an excavator is used as a metaphor
[02:08.66]Hydrolysis can be interpreted as
[02:10.86]Use the bucket to break down a stone
[02:13.62]Break down into pieces and sand
[02:16.11]As for the saponification reaction
[02:18.66]Replace the bucket with a breaking hammer
[02:21.03]Corresponding to efficient decomposition of fat molecules
[02:25.50]What is obtained is a plurality of pieces and powder
[02:53.22]The chemical properties of fat include
[02:55.53]Its hydrolysis and its saponification
[02:58.44]Triglycerides react with water
[03:00.78]Produce glycerol and fatty acids
[03:03.42]Chemical properties of fat
[03:05.64]Perorated by reaction
[03:06.90]Not only hydrolysis and saponification
[03:11.13]And hydrogenation and iodination
