Functional structural oil as well as preparation method and application thereof

Abstract

The invention relates to functional structure oil, which is formed by carrying out quaternary ester exchange on camphor tree seed kernel oil, caprylin, linoleic acid grease and linolenic acid grease. The preparation method comprises the following steps: directly carrying out quaternary ester exchange on camphor tree seed kernel oil, caprylin, linoleic acid grease and linolenic acid grease at proper temperature and stirring intensity by taking lipase as a catalyst, and carrying out molecular distillation purification to obtain the functional structure oil. The functional structure oil can significantly improve in-vivo glucose and lipid metabolism disorder, balance and supplement in-vivo necessary and functional fatty acids, and quickly supplement energy, and can meet the requirements of consumers. Particularly, the dietary and nutritional requirements of patients with metabolic syndromes such as overweight, obesity, fatty liver, hyperlipidemia, hyperglycemia, hypertension, hyperblood viscosity, hyperuricemia and hyperinsulinemia and athletes can be met, and the food can be widely applied to the industries of grease powder, milk tea, meal replacement powder, health food, sports nutritious food and food for special medical purposes.

Description

technical field [0001] The invention belongs to the technical field of edible fats and oils. Background technique [0002] In recent years, research results on medium- and long-chain structural lipids have been published at home and abroad. Medium-chain triglycerides and long-chain triglycerides undergo fatty acyl exchange under catalytic conditions to form medium- and long-chain triglycerides and by-products. Compared with the mixture of pure medium-chain oil and long-carbon-chain oil, the physical and chemical properties and efficacy of medium- and long-chain structured lipids are very different. [0003] Medium-chain fatty acids contained in medium-chain oils include caprylic acid (abbreviated as C), capric acid (capric acid, abbreviated as Ca), and lauric acid (abbreviated as La). Medium-chain fats are absorbed, transported, and metabolized in the body in the form of free medium-chain fatty acids. Small molecular weight, high solubility in blood, short half-life, in v...

Problems solved by technology

[0010] Chinese patent (CN 107828830 A) discloses a method for adjusting the composition of medium- and long-chain triglycerides. The weight ratio of soybean oil to medium-chain triglycerides is 2:1-15:1, and the content of medium-chain fatty acids is less than 50 %, and did not consider the proportion of essential fatty acids

[0012] Chinese patent (CN 102140390A) discloses a method for synthesizing medium / long-chain structural triglycerides. The medium-chain triglycerides and long-chain triglycerides are weighed at a molar ratio of 1:0.5-2 for transesterification. The content can reach 70-80%, but the purity is still not high, and the content of medium-chain fatty acids is less than 50%, without considering the ratio of essential fatty acids

[0014] Chinese patent (CN 105821089A) discloses an enzymatic method for medium- and long-chain structured triglycerides, in which long-chain and medium-chain triglycerides are weighed at a molar ratio of 1:0.5-5 for transesterification, and the structural lipids The content can reach 70-80%, but the purity is not high, and the proportion of essential fatty acids is not considered

[0019] First, the current domestic and foreign patents on medium and long-chain triglycerides basically have relatively large limitations, such as high cost, complicated and time-consuming operation, and the final product has a low content of structural lipids, making it difficult to realize industrialization

[0020] The second is that the caprylic and capric acid medium-chain oils produced and sold at home and abroad are still artificially produced by hydrolysis or cracking, separation, and esterification using vegetable oils with caprylic and capric acid content less than 10% (w / w) as raw materials. Synthetic products, which are energy-intensive and costly to produce and essentially free of lauric acid

And the camphor tree seed kernel oil that belongs to natural medium-chain oil and fat contains medium-chain fatty acid and reaches 95.60~98.50% (containing caprylic acid 0.32~0.47%, capric acid 56.49~61.98%, lauric acid 34.18~39.20%), but do not see relevant utilization camphor tree seed Literature reports on the development and production of functional structural oils from kernel oil

[0021] The third is that there is no basis for optimizing the fatty acid composition of structural lipids and determining the physiological effects of structural lipids based on the results of animal experiments

[0022] Fourth, all kinds of medium and long carbon chain structural lipids are not involved in the physiological effects of improving glucose and lipid metabolism disorders in the body and supplementing essential fatty acids (linoleic acid, linolenic acid) at the same time

In the existing invention products and technologies, the ratio of linolenic acid to linoleic acid is still seriously unbalanced
