Embodiment 1

[0028] like figure 2 As shown, a method for preparing medium and long-chain fatty acid edible oil comprises the following steps:

[0029] Step 1. Preliminary preparation, vacuuming the reaction tank, heating up and dehydrating;

[0030] Step 2: Mixing raw materials, 14 parts of medium chain fatty acids, 2 parts of glycerol, 46.9 parts of sunflower oil, 34 parts of soybean oil, 3 parts of linseed oil, and 0.1 part of vitamin E, put into the reaction tank in turn, and vacuumed at 95 ° C Dehydration, then stirring and mixing for 10min to obtain the oil mixture before the reaction;

[0031] Step 3, esterification reaction, put the immobilized lipase into a fixed container to form a lipase fixed bed, let the pre-reaction oil mixture cooled to 65°C circulate through the lipase fixed bed for transesterification, and terminate the reaction after 8 hours of reaction , the catalyst and grease are separated;

[0032] Step 4, refining and processing, carrying out refining operations s...

Embodiment 2

[0035] like image 3 As shown, a method for preparing medium and long-chain fatty acid edible oil comprises the following steps:

[0036] Step 1. Preliminary preparation. The reaction tank is equipped with a stirrer. The vertical stirring of the agitator can make the materials mix efficiently from bottom to top. The reaction tank is first evacuated and heated for drying and dehydration;

[0037] Step 2, mixing raw materials, 20 parts of medium-chain fatty acids, 5 parts of glycerol, and 75 parts of soybean oil, put into the reaction tank successively, dehydrated in vacuum at 95 ° C, and then stirred and mixed for 10 min to obtain the oil mixture before the reaction;

[0038] Step 3, esterification reaction, before the reaction, the oil mixture is cooled to 45°C, lipase is added, and the transesterification reaction is carried out, and the reaction is terminated after 24 hours;

[0039] Step 4, refining and processing, refining the structural fat obtained by the esterification...

Embodiment 3

[0042] like Figure 4 As shown, a method for preparing medium and long-chain fatty acid edible oil comprises the following steps:

[0043] Step 1. Preliminary preparation, first vacuum dry the mixing tank for use;

[0044] Step 2: Mix the raw materials, put 11% of medium chain fatty acid, 2% of glycerol, 86.9% of vegetable oil and 0.1% of vitamin E into the mixing tank, which accounts for 11% of the total mass of the mixture before the total reaction. , mixed for 10min to make it uniform. Among them, 86.9% of vegetable oils include: 70.9% rapeseed oil, 16% coconut oil;

[0045] Step 3, esterification reaction, put the immobilized lipase into the fixed-bed reactor, let the mixture cooled to 60 ° C flow through the fixed-bed reactor to carry out the transesterification reaction, the reaction is terminated after 10 hours, and the catalyst and grease are separated. ;

[0046] Step 4, refining and processing, refining the structural fat obtained by the esterification reaction t...

Abstract

The invention discloses a preparation method of medium-chain and long-chain fatty acid edible oil, and relates to the field of edible oil and fat. The preparation method of the medium-chain and long-chain fatty acid edible oil comprises the following steps: step 1, early-stage preparation: vacuumizing and heating a reaction tank so as to remove water; step 2, raw material mixing: uniformly mixing medium-chain fatty acid with glycerol and vegetable fat in a reaction tank to obtain a fat mixture; step 3, esterification reaction: carrying out esterification reaction on the grease mixture in vacuum and at a certain temperature by taking lipase as a catalyst; step 4, refining processing: after the esterification reaction is completed, refining a crude product obtained from a reaction product to obtain a finished product of the medium-chain and long-chain fatty acid edible oil; the main characteristic component of the finished product medium-and-long-chain fatty acid edible oil prepared in the step 4 is medium-and-long-chain fatty glyceride. The preparation method provided by the invention has the characteristics of high reaction efficiency, low raw material price, low energy consumption and the like.

Description

technical field [0001] The invention belongs to the field of edible oils and fats, in particular to a method for preparing medium and long-chain fatty acid edible oils. Background technique [0002] Fat is one of the important nutrients that the human body needs, supplying energy and essential fatty acids needed by the body. In recent years, with the development of lipid nutrition and the advancement of clinical metabolic research technology, it has been found that natural oils are closely related to a variety of diseases, such as cardiovascular disease, three highs and obesity. The high incidence of many chronic diseases such as obesity, cardiovascular and cerebrovascular diseases, and diabetes has become the number one killer of health in China. In the future, functional structural oils will play an important role in the prevention and treatment of chronic diseases. [0003] Structural lipids, as the main products of oil transesterification at present, have a wide variety...
