example 1

[0040] Example 1, 15g of cellulase with an enzyme activity unit of 10000U / g was dissolved in 10kg of water to make an enzyme aqueous solution, and 10kg of fresh wet coconut bran obtained after squeezing the coconut milk was stirred and mixed with the enzyme aqueous solution, and incubated at 50°C for 3 hours. Then add 30kg of warm water at 50°C to stir, further pulverize the homogenate with a colloid mill, and keep the resulting slurry at 50°C for 2 hours, and use a pressing method to separate the pulp residue to obtain coconut dregs and thin coconut milk. After standing for 2 hours, the thin coconut milk is divided into 4 layers: free oil layer, emulsified layer, whey layer and sediment layer. The free oil layer, the emulsified layer, the whey layer and the precipitated layer are taken out respectively. The free oil layer and the emulsified layer are combined to obtain about 4kg oil-emulsion mixture, add 2kg water in the oil-emulsion mixture, add salt to make the salt concent...

example 2

[0041] Example two, 10g enzyme activity unit is the xylanase of 10000U / g, 5g enzyme activity unit is the papain of 1000000U / g, 50g salt is dissolved in 10kg water to make enzyme aqueous solution, will squeeze the fresh 10kg obtained after coconut milk Stir and mix wet coconut bran and enzyme aqueous solution, keep it warm at 55°C for 3 hours, then add 30kg of warm water at 50°C and stir, use a colloid mill to further pulverize and homogenate, keep the obtained slurry at 45°C for 1 hour, and separate the pulp and residue by pressing method to obtain Coconut dregs and thin coconut milk. After standing for 1 hour, the thin coconut milk is divided into 4 layers: free oil layer, emulsified layer, whey layer and sediment layer. The free oil layer, the emulsified layer, the whey layer and the precipitated layer are taken out respectively. The free oil layer and the emulsified layer are combined to obtain about 4.5kg oil-emulsion mixture, add 4kg water in the oil-emulsion mixture, ad...

[0042] Example three, 10g of cellulase with enzyme activity unit of 10000U / g, 10g of enzyme activity unit of 10000U / g xylanase, 5g of enzyme activity unit of β-glucanase with 10000U / g, 5g of enzyme activity Papain with a unit of 1000000U / g and 40g of salt were dissolved in 10kg of water to make an enzyme aqueous solution, and 10kg of fresh wet coconut bran obtained after extracting coconut milk was mixed with the enzyme aqueous solution, kept at 50°C for 2 hours, and then 30kg of 50 Stir in warm water at °C, further pulverize the homogenate with a colloid mill, keep the resulting slurry at 45°C for 1 hour, and separate the pulp residue by pressing to obtain coconut dregs and thin coconut milk. After standing for 1 hour, the thin coconut milk is divided into 4 layers: free oil layer, emulsified layer, whey layer and sediment layer. The free oil layer and the emulsified layer are combined to obtain about 4.8kg oil-emulsion mixture, add 4kg water in the oil-emulsion mixture, add ...

Abstract

The invention discloses a method used for extracting coconut oil from a coconut cake, and the steps are: one or more than two of cellulose, hemicellulase or papain are combined to make into enzyme water solution with which the coconut cake is mixed and stirred, kept warm, stirred with warm water and further grinded by a colloid mill; serous fluid obtained obtains thin coconut cream after going through tailings separation; the thin coconut cream goes through layers separation after placed stilly; a free oil layer, an emulsion layer, a serum layer and a precipitation bed are taken out respectively; the obtained free oil layer and the emulsion layer are mixed together to obtain oil emulsion mixture in which water and salt are added, and then the papain is added for continuing zymolysis and the salt is added for supplementing; the mixture is placed stilly to lead the free oil to float upward to get the coconut oil; the coconut oil is extract out, washed by water and filtered, and high-quality coconut oil with the water content less than or equal to 0.1 percent is obtained after going through vacuum drying. The invention has simple technique process, low production cost, high oil production rate, little pollution, high product quality and high comprehensive utilization value of byproducts.

Description

technical field [0001] The invention relates to a method for extracting coconut oil, in particular to an enzymatic extraction method for extracting coconut oil from coconut bran by enzymatic hydrolysis and utilizing the physical and chemical properties of table salt to improve coconut oil. Background technique [0002] Existing extraction and preparation methods of coconut oil include dry processing technology and wet processing technology. The dry processing process is to expose the coconut meat to high temperature or sunlight for a period of time until most of the water is removed to make copra, and then use an oil press to squeeze the copra to obtain coconut oil. The process of copra oil extraction has developed into a method of combining cold pressing and solvent extraction in recent years, which can significantly increase the oil yield. The pressing equipment used ranges from rotary oil presses to modern water press oil presses and continuous screw oil presses, etc., b...
