Problems solved by technology

The traditional dry extraction method is to dry the coconut meat and press it. However, when using this method, the coconut meat will brown after drying, resulting in a darker color of the extracted coconut oil, and the high temperature during pressing will also destroy some of the coconut oil. functional substances
The current wet extraction technology is to refine the coconut meat, heat it and then centrifuge to obtain oil. However, the extraction rate of coconut oil using this method is not high, and the extracted coconut oil has high water content, which is not conducive to preservation.
Organic solvent extraction method is also very commonly used, but organic solvent extraction consumes a lot of energy, costs a lot, and pollutes the environment. Organic solvents will remain in the oil, which is harmful to the human body after eating.

Embodiment 1

[0025] 1) drying and crushing: 100g coconut meat is cleaned and cut into 5cm long, 5cm wide, and 2cm thick strips, then put the cut coconut meat into a vacuum freezer for vacuum freeze-drying, the vacuum degree is 1Pa, and the temperature is -40 ℃ of drying 20h, the electron microscope figure of present embodiment coconut meat after vacuum freeze-drying is as follows figure 1 After drying, take it out and store it in a cool, dry place under airtight seal. The coconut meat processed by vacuum freeze-drying is crushed to a paste state, and then taken out for later use.

[0026] 2) enzymolysis: the coconut meat after pulverizing is added 500g water and mixes and makes mixture I, adds the composite enzyme of 0.5% of mixture I weight, and described composite enzyme is that cellulase and papain are mixed, and described cellulose The mass ratio of enzyme to papain is 1:0.5, and the enzyme is hydrolyzed in a water bath at 45°C for 12 hours. Inactivate the enzyme at 85°C for 30 minut...

Abstract

The invention discloses an extraction method for coconut oil. The extraction method comprises the following steps: carrying out vacuum freezing and drying treatment on coconut meat; smashing the dried coconut meat; adding a compound enzyme into the mixed smashed coconut meat and water for enzymolysis treatment; carrying out centrifugalization after enzymolysis; taking upper layer grease; and carrying out vacuum drying on the upper layer grease to obtain natural coconut oil with a relatively good quality. By adopting the extraction method for coconut oil disclosed by the invention, the coconut meat obtained by adopting the vacuum freezing and drying technology is smooth and porous, and the destroy degree of coconut meat cells is improved, so that the dissociating degree of oil in the coconut meat is improved. Moreover, the water emulsion degree of the prepared coconut oil is greatly reduced, the extraction rate of the coconut oil is improved in a condition that the natural components of the coconut meat is not destroyed, the prepared coconut oil is excellent in quality, low in cost and pollution-free, and the prepared coconut oil product is harmless to human body and has a good application prospect.

Description

technical field [0001] The invention relates to the field of food, in particular to a method for extracting coconut oil. Background technique [0002] Raw coconut oil is a kind of vegetable oil extracted from fresh mature coconut meat by mechanical or natural methods, with or without heating. It is composed of medium-carbon chain fatty acids. The medium-chain fat molecules are smaller than the long-chain fat molecules of other foods, and are easily digested and absorbed by the human body. The digestion of dietary coconut oil does not require the use of human pancreatic digestive enzyme system, which exerts little pressure on the body's enzyme and hormone systems. Moreover, the liver is more inclined to use medium-chain fatty acids as a fuel source for energy production, thereby improving the efficiency of metabolism. Coconut oil has the functions of lowering bad cholesterol, increasing good cholesterol, easy to digest, helping to lose weight, preventing metabolic syndrome c...
