Determining the drop point of edible oil by automatic drop point determination technology (CAT#: STEM-PPA-0195-LJX)

Introduction

Edible oils and fats are lipid materials that are generally soluble in organic solvents but insoluble in water. While oils and fats are chemically similar in that both are composed of triglycerides, the distinction between them is that fats are solid at room temperature, while oils remain liquid.
Edible oils and fats including cooking oils are an essential part of everyday life and can be derived from animal, vegetable or even synthetic sources, and their consumption enables the fulfillment of both structural and metabolic functions in the body. They can be ingested directly or as components of prepared foods, to which they may lend flavor or texture. Edible oils and fats may find additional use in the production of soaps and other skin care products, candles, and perfumes. When processing oils and fats, robust quality control is a must.




Principle

During the test, the cup containing the sample is placed on the support, and the furnace is installed on the outside of it. The expected drop point temperature of the sample is set through the instrument keyboard, and the temperature is raised according to the preset heating program. The photodetector automatically records the temperature at which the first drop of sample is dropped from the mouth of the cup, which is the drop point of the sample.

Applications

For drop point determination of non-crystalline materials such as synthetic and natural products

Procedure

1. Place the sample in the cup and put it on the support in the furnace
2. Start the instrument program to heat up
3. The instrument automatically records the temperature at which the first drop of sample drops from the mouth of the cup, that is, the drop point

Materials

• Sample Type:
Edible oil

Notes

The experiment should be repeated three times, and the average value should be taken to ensure the accuracy of the results.
