Example Embodiment

[0026] Example 1

[0027] A method for extracting coconut oil includes the following steps:

[0028] 1) Refining 100g coconut meat and 300g water to obtain coconut milk Ⅰ

[0029] 2) Put the coconut milk I into an ultrasonic microwave synergistic extraction instrument for processing, the processing time is 10 minutes, and then cool to 25°C to obtain coconut milk II;

[0030] 3) Add 1 g of complex enzymes to the coconut milk II, enzymatically hydrolyze in a water bath for 24 hours, the temperature of the hydrolyzed water bath is 40°C, and perform enzyme inactivation treatment for 30 minutes after enzymatic hydrolysis in the water bath to obtain coconut milk III;

[0031] The compound enzyme is prepared from 1g cellulase, 3g papain and 1g β-glucanase;

[0032] 4) Centrifuge the coconut milk III at a centrifugal speed of 3000 r / min and a centrifugal time of 10 min. The coconut oil is obtained by absorbing the supernatant oil.

Example Embodiment

[0033] Example 2

[0034] A method for extracting coconut oil includes the following steps:

[0035] 1) Refining 100g coconut meat and 400g water to obtain coconut milk Ⅰ

[0036] 2) Put the coconut milk I into an ultrasonic microwave synergistic extraction instrument for processing for 5 minutes, and then cool to 40°C to obtain coconut milk II;

[0037] 3) Add 2 g of complex enzymes to the coconut milk II, enzymatic hydrolysis in a water bath for 36 hours, and a temperature of 55°C for enzymatic hydrolysis in a water bath. After enzymatic hydrolysis in the water bath, enzymatic inactivation is performed for 30 minutes to obtain coconut milk III;

[0038] The composite enzyme is prepared from 1g cellulase, 1g papain and 1g β-glucanase;

[0039] 4) Centrifuge the coconut milk III at a centrifugal speed of 5000 r / min and a centrifugal time of 20 min. The coconut oil is obtained by absorbing the supernatant oil.

Abstract

The invention discloses a coconut oil extraction method, which comprises the following steps of grinding coconut flesh into pulp; performing microwave ultrasonic processing on the coconut pulp; performing enzymolysis and centrifugation; taking upper layer clean oil to obtain coconut oil. When the coconut oil extraction method provided by the invention is used, under the conditions of not using organic solvents or not adopting high-temperature processing, the damage to nutrition substances is reduced; the method is simple and safe; the oil yield is high; the cost is low; the energy consumption is low; residue liquid after the oil and grease extraction contains rich protein and polypeptide and can be recovered and reused; the residue solid contains rich dietary fiber and polysaccharide, and can be used as animal feed or can provide carbon sources for microorganism fermentation; waste water can be easily processed; substances harmful to environment cannot be generated; the prepared coconut oil is clear and transparent, has intense coconut fragrance and has good application prospects.

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...
