3.4.2. Saccazozo sugar.
Sugar is sugar Saccarozo without reducing properties since it does not eliminate a solution Felin. In acid conditions, saccharose hydrolysis mixture Glucose and Fructose inverse way, this way reducing sugar mixture.
Determination of reducing sugars by the method or methods of methylene blue Bertrand. From then calculate the sugar sucrose.
Notice when determining sugar sucrose to determine the initial reducing sugar content in advance.
3.5. Determination of fat.
Determination by Soxhlet device.
The majority of raw materials used for processing foods contain a certain fat content. Therefore, the determination of the fat content is very necessary. Not only does it evaluate the quality of the material, which in some cases need to know the fat content to put out the processing technology.
- Based on the properties of the fat is completely dissolved in organic solvents.
- Used organic solvent extraction of fat in their food products.
Then the solvent evaporated, the remaining fat weighed, counted the fat content in food products.
