What is saponification value?
The saponification value is defined as “the number of milligrams of KOH needed to neutralize the fatty acids obtained by complete hydrolysis of 1gram of an oil sample.”
How is RM value determined?
The RM value is determined when examining fat. It is an indicator of how much volatile fatty acid can be extracted from fat through saponification. All tested brands met the requirements set by the national standards.
What is polenske value of milk?
The Polenske value for milk fat ranges from 1.2 to 2.4. This value for other oils and fats [5,16] is also low (less than 1) except the coconut oil (15-20) and palm kernel oil (6-12).
What is polenske value of ghee?
The Polenske value is the number of m1 of 0.1 N aqueous alkali solution required to neu-tralize the water-insoluble stream volatile fatty acids distilled from 5g of ghee under the precise conditions specified in the method.
What is Reichert Meissl value of oil?
The Reichert value is an indicator of how much volatile fatty acid can be extracted from fat through saponification. It is equal to the number of ml of 0.1 normal hydroxide solution necessary for the neutralization of the water-soluble volatile fatty acids distilled and filtered from 5 grams of a given saponified fat.
What is Reichert Meissl value of ghee?
The highest Reichert-Meissl value was 31.11 was and the lowest Reichert-Meissl value was 0.23 in all samples analyzed.
How is oil converted into fat?
Oils are convereted into fats by hydrogenation. Oils contain unsaturated fatty acids which one hydrogenation becomes saturated fatty acids (fats contain saturated fatty acid).
What is Polanski number?
The Polenske value (also known as the Polenske number) is a value determined when examining fat. It is an indicator of how much volatile fatty acid can be extracted from fat through saponification.
What is the acetyl number?
n. Number of milligrams of potassium hydroxide required to neutralize the acetic acid set free from 1 g of an acetylated compound when the latter is subjected to hydrolysis.
Why do we determine saponification value?
The higher the saponification value, the lower the fatty acids average length, the lighter the mean molecular weight of triglycerides and vice-versa. Practically, fats or oils with high saponification value (such as coconut and palm oil) are more suitable for soap making.
