Problems solved by technology

The quality of coconut oil produced by wet processing is better than that obtained by dry processing, but the high-speed centrifuge is expensive and the investment in equipment is large
At present, coconut milk is naturally fermented for more than one day, and then coconut oil is extracted by heat treatment and centrifugation, but the oil yield of this method is low, and other by-products after separating coconut oil are difficult to use due to rancidity.
Whether it is dry processing or wet processing, the depth and breadth of the utilization of by-products after extracting coconut oil are not enough at present, and the utilization value of by-products is not high, and the obtained coconut oil contains a certain amount of free fatty acids. , if it contains a certain amount of water, it is very easy to oxidize and lose

Embodiment 1

[0025]Embodiment 1, get 7 mature fresh papayas and peel, remove seeds, cut into pieces, beating, and filter with a 200-mesh sieve to obtain papaya pulp; fresh coconut meat after peeling is crushed and squeezed to obtain coconut milk. Add 20kg of papaya pulp to 100kg of coconut milk, add 60kg of water, add 80g of pectinase, stir and mix, keep warm at 50°C for 4 hours, and then divide the solution into oil layer, emulsified layer, whey layer and sediment layer, and take out each Layer, obtain 100kg whey, 4kg precipitation layer. The oil layer and the emulsified layer were combined to obtain 76kg of oil-emulsion mixture, 94kg of water was added to the oil-emulsion mixture, and after the enzymatic hydrolysis was continued at 52°C for 12 hours, 30kg of sucrose was added, and the free oil was allowed to float at 50°C for 8h to obtain clear coconut oil. Separate the upper layer of coconut oil from the lower layer of water. Add 1 times water to coconut oil and wash twice to remove re...

Embodiment 2

[0026] Embodiment two, get the fresh papaya that has 8 ripeness to peel, remove seed, cut into pieces, beating, filter with 200 mesh screens, obtain papaya pulp; The fresh coconut meat after peeling the seed coat is crushed and squeezed to obtain coconut milk, and Add 30kg of papaya pulp to 100kg of coconut milk, add 40g of pectinase, then add 50kg of water, stir and mix, keep warm at 53°C for 8 hours, and then divide the solution into oil layer, emulsified layer, whey layer and sediment layer, and take out each layer separately , Obtain 97kg whey, 3kg sedimentation layer and a total of 80kg oil layer and emulsification layer (ie oil-emulsion mixture). Add 90kg of water to the oil-emulsion mixture, continue to incubate at 50°C for 12 hours, then add 40kg of sucrose, let stand at 52°C for 6 hours to float the free oil to obtain clear coconut oil. Separate the upper layer of coconut oil from the lower layer of water. Add 2 times of water to the coconut oil and wash the coconut ...

Abstract

The invention discloses a preparation method of coconut oil by treating coconut milk with pawpaw juice, which is characterized in that: 60-90 percent maturated fresh pawpaw are prepared and made into pawpaw juice while the fresh coconut meat is mashed and pressed into coconut milk; then water, pawpaw juice and pectinase are added into coconut milk, mixed together and then treated with zymohydrolysis in heat insulation; after standing, the solution is divided into oil layer, emulsion layer, serum layer and precipitation layer which are taken out respectively; a oil emulsion mixture obtained by mixing the oil layer and the emulsion layer is added with water and then treated with zymohydrolysis in heat insulation, added with white sugar and treated with standing for stratification; the upper coconut oil layer which is separated from the lower water layer is washed with water and filtered and then treated with vacuum drying to produce high-quality coconut oil which contains Beta-carotene. The invention has simple technical process, low cost, high oil-production efficiency, high comprehensive utilization rate of side products, low pollution, meanwhile the coconut oil produced which contains natural Beta-carotene has beautiful colors and long guarantee period.

Description

technical field [0001] The invention relates to a method for preparing coconut oil by using papaya pulp, in particular to a method for extracting coconut oil containing beta-carotene from coconut milk by using papaya pulp. Background technique [0002] Papaya is one of the famous tropical fruits. Its fruit has high nutritional value and contains papain, papain, rennet, etc. It is rich in more than 17 kinds of amino acids and various nutritional elements. The oleanolic acid contained in it It is a compound that has the functions of protecting the liver, reducing enzymes, anti-inflammatory and antibacterial, and lowering blood lipids. Papaya is rich in vitamins A, B, and B 1 , B 2 , C, etc., contain a variety of minerals such as iron, calcium, potassium, etc. Papaya contains so many nutrients that it can almost be called the king among all fruits. What is more important is that the "papain" (papain) contained in the milky juice of papaya is one of the ...
