Problems solved by technology

However, since fat plays an important role in the taste, flavor, and texture of food, it is impossible to completely remove fat from the diet, and reducing the amount of fat will also seriously affect the quality of food
For the health of the body, people need to control the fat intake in the diet, but many consumers cannot accept the rough taste of simply reduced-fat or fat-free foods, so the development of low-calorie fats is an important development direction of the food technology industry

Embodiment 1

[0021] Soybean oil 30kg, glycerol 2.9kg, consumption is 0.1% tetrabutylammonium chloride and K 2 SO 4 co-catalysis at 130 °C, N 2 Glycerol hydrolysis was carried out under protection for 40 min, and then the glycerol was removed by centrifugation. Esterification was carried out under reflux conditions. Firstly, acetic acid was used in an amount of 3.3 kg for 2.0 h, and then acetic anhydride was used for 1.0 h in an amount of 3.3 kg to obtain a crude product. Finally, refining processes such as alkali refining and dehydration are carried out to obtain finished products. The proportion of long and short chain acylglycerides in the mixture is 65% (percentage by weight), and the heat is 27% of the raw material oil.

Embodiment 2

[0023] Peanut oil 30kg, glycerin 3.5kg, consumption is the tetrabutyl ammonium bromide of 0.1% of raw material and K 2 SO 4 co-catalysis at 120 °C, N 2 Glycerolysis was carried out under protection for 100 min, and then the glycerol was removed by centrifugation. Esterification was carried out under reflux conditions. Firstly, acetic acid was used in an amount of 3.7 kg for 2.0 h, and then acetic anhydride was used for 1.3 h in an amount of 3.1 kg to obtain a crude product. Finally, refining processes such as alkali refining and dehydration are carried out to obtain finished products. The proportion of long and short chain acylglycerides in the mixture is 73% (percentage by weight), and the heat is 30% of the raw material oil.

Embodiment 3

[0025] Rapeseed oil 30kg, glycerin 2.9kg, consumption is 0.1% tetraethylammonium chloride and Na 2 SO 4 co-catalysis at 110 °C, N 2 Glycerolysis was carried out under protection for 150 min, and then the glycerol was removed by centrifugation. Esterification was carried out under reflux conditions. Firstly, propionic acid was used in an amount of 3.3 kg for 2.0 h, and then propionic anhydride was used for 1.0 h in an amount of 3.3 kg to obtain a crude product. Finally, refining processes such as alkali refining and dehydration are carried out to obtain finished products. The ratio of long and short chain acylglycerides in the mixture is 68% (percentage by weight), and the heat is 28% of the raw material oil.

Abstract

The present invention discloses a method for producing low calorie oil which is liquid at normal temp. by general vegetable oil and adopting ester exchange process. Said invented product has reasonable fatty acid structure, and can provide enough fatty acid required for human body. It can be used as industrial oil and domestic edible oil.

Description

1. Technical field [0001] The invention belongs to the transesterification of vegetable fats and oils, which is a method for preparing a long-short-chain low-calorie fat which is liquid at normal temperature by esterifying upper-short-carbon-chain acids. 2. Background technology [0002] Fat plays a pivotal role in human health. With the continuous improvement of people's living standards, oil and fat products are playing an increasingly important role in the diet with their attractive taste and fragrance. However, a large amount of fat intake in the diet has brought more and more obvious side effects to human health. Nutritional and medical research has shown that the so-called "diseases of wealth" such as malignant tumors, hyperlipidemia, hypertension, arteriosclerosis, coronary heart disease, obesity, and diabetes are directly related to the excessive calories provided by fat in people's daily diet. According to the latest medical research data, 155,000 people in the Un...
