Significance of Ester value

Ester value is a crucial parameter in assessing the quantity of esters present in a sample, calculated by the difference between saponification and acid values. Specifically, it represents the milligrams of potassium hydroxide needed to saponify the esters in one gram of a substance. This measurement is indicative of the total ester content in oils and fats, helping determine their quality and composition, with higher ester values generally correlating to better preservation against rancidity.

The concept of Ester value in scientific sources

Science Books

Ester value measures the ester content in a substance, calculated as the potassium hydroxide needed for saponification. It reflects the esters formed during saponification and is derived from the saponification minus the acid value.

Significance in Scientific journals, articles, etc.:

From: World Journal of Pharmaceutical Research

(1) The measure of the total ester content in an oil, which helps determine its quality and composition.[1] (2) A measure of the total ester content in the formulation, indicative of the quality of fats and oils used.[2] (3) The number of milligrams of potassium hydroxide required to saponify the ester in one gram of a substance.[3] (4) The number of milligrams of potassium hydroxide required to saponify the esters contained in one gram of a substance.[4]

From: Journal of Ayurveda and Holistic Medicine

(1) The value derived from the saponification value minus the acid value, indicating the amount of ester present.[5] (2) The amount of potassium hydroxide required to saponify the esters present in 1 gram of a substance, providing insights into the ester content of the oil.[6]

From: AYU (Journal of Research in Ayurveda)

(1) A metric used to measure the amount of esters formed during the saponification process in fatty substances.[7]

From: International Ayurvedic Medical Journal

(1) Reflects the amount of esterified fatty acids present, with higher values correlating to better preservation against rancidity.[8]

From: Ayushdhara journal

(1) A parameter indicating the amount of ester in the sample, calculated from the difference between saponification and acid values.[9]
