Problems solved by technology

However, medium-carbon chain fatty acids are not essential fatty acids for the human body, nor can they be converted into functional fatty acids in the body, and cannot provide essential fatty acids and functional fatty acids required for human growth and development.
[0008] At home and abroad, coconut oil and palm kernel oil with caprylic acid and capric acid content less than 15% (w / w) are still used as raw materials to produce caprylic capric acid, which can quickly replenish energy in the body, through hydrolysis, separation, and esterification. Carbon chain oil products contain only caprylic acid (content is about 51%, w / w) and capric acid (content is about 49%, w / w), and its production energy consumption and production cost are high

Embodiment 1

[0036] The fatty acid composition and distribution of the camphor tree seed kernel oil used are shown in Table 1. According to the mass ratio of caprylic acid and camphor tree seed oil to be 0.3, 0.4, 0.5, 0.6, take appropriate amount of caprylic acid and camphor tree seed kernel oil respectively in different esterification reactors, and weigh 10% (w / w) of the mixed oil quality Add lipase Staphylococcus caprae lipase. Magnetic stirring, the reaction temperature is 40°C, and the reaction time is 4h. After the binary transesterification reaction, lipase is separated for repeated use, and free fatty acids such as lauric acid are separated to obtain a series of caprylic acid and capric acid lauryl with the mass ratios of caprylic acid and camphor tree seed oil being 0.3, 0.4, 0.5, 0.6 respectively Acid medium carbon chain oil, determine its fatty acid composition and freezing point. The solidification points of the series of caprylic acid, capric acid and lauric acid series medi...

Abstract

The invention relates to caprylic / capric acid-lauric acid medium-carbon chain oil and a preparation method and application thereof. Camphor tree seed kernel oil and caprylic acid are subjected to binary ester exchange, and fatty acid on glycerol skeleton molecules of the camphor tree seed kernel oil is recombined,the fatty acid incaprylic / capric acid-lauric acid medium-carbon chain oil is calculated by mass and the mass ratio of caprylic acid to the camphor tree seed kernel oil in the caprylic / capric acid-lauric acid medium-carbon chain oil is 0.3-0.6. Camphor tree seed kernel oil is utilized to construct the caprylic / capric lauric acid medium-carbon chain oil product capable of rapidly supplementing energy in a body and remarkably improving glucose and lipid metabolism disorder in the body, high-value utilization of camphor tree seed resources can be promoted, the situation that medium-carbon chain oil products in China mainly depend on import is ended, and the diet and nutritional requirements of consumers, especially patients with metabolic syndrome, athletes, patients with long-carbon-chain fatty acid transport, metabolism and absorption disorders and critical patients are met.

Description

technical field [0001] The invention belongs to the technical field of edible oils and fats. Background technique [0002] Fatty acids are divided into short-chain fatty acids (fatty acids with 2-6 carbon atoms, Short-chain fatty acids, abbreviated as SCFA) and medium-chain fatty acids (fatty acids with 8-12 carbon atoms, Medium- chainfatty acids, abbreviated as MCFA), long-chain fatty acids (fatty acids with more than 12 carbon atoms, Long-chain fatty acids, abbreviated as LCFA), according to whether the body can synthesize them into essential fatty acids (Essential fatty acids, abbreviated as EFA), Non-essential fatty acids (Non-essential fatty acids, abbreviated as NEFA). [0003] Oils and fats are mixed fatty acid glycerides. According to the number of carbon atoms of the fatty acids connected to the glycerol skeleton molecules of oils and fats, they can be divided into Long-Chain Triglycerides (LCT for short), Medium and Long-Chain Triglycerides for short (LCT for shor...
