General information
Determination of Fat
Fat analysis is used to determine the fat content and fat composition of foodstuffs. Individual components or total fats levels can be calculated depending on the purpose of testing. Different components are subject to different procedures by law, such as the Gerber method or the Van Gulik technique.
• Add sample to 60 ml water
• Subsequently add, while mixing after each step:
a) 5 ml Carrez-I-solution, Art. No. 9944
(or 7,2 g zinc sulphate heptahydrate, Art. No. K301 ad 100 ml)
b) 5 ml Carrez-II-solution, Art. No. 9950
(or 3,6 g potassium hexacyanoferrate(II), Art. No. P745 ad 100 ml)
• Adjust pH to 7,5 - 8,5 by adding NaOH (0,1 M) Art.No. K020
• Fill volumetric flask up to mark, mix, and filter
Acid Value Determination
The acid number characterises the acidic components of the fats. For this purpose, the sample is dissolved in a solvent and titrated against phenolphthalein with potassium hydroxide solution. Only free fatty acids are recorded. The fatty acids bound in the glycerides are not determined.
Highest purity and extensive trace analysis for excellent results!
We offer:ROTIPURAN® p.a. solvents with superior analytical reliability in terms of quality and batch consistency. The so branded solvents arebeing constantly controlled, guaranteed, and safeguarded through careful preparation, testing and packaging. In addition, many of these solvents meet the requirements of ACS (American Chemical Society) and ISO (International Organization for Standardization), and thusare fully specified.
Applications:ROTIPURAN® p.a. solvents are suitable for all standard applications in biological and chemical laboratory or pilot plant, such as:extractions, qualitative and quantitative analysis. As a matter of course, the p.a. solvents offered here may well be used for otherapplications instead.
