Embodiment 1

[0010] After 50Kg of white coconut meat is crushed, it is ground together with 190 liters of buffer solution; 0.45Kg of compound enzyme is added, and the compound enzyme is composed of pectinase, amylase and protease in a mass ratio of 50:30:35, and is enzymolyzed at 60°C Leach for 3.5 hours; heat up to 90°C and keep for 10 minutes, and use a filter press to separate the solid and liquid; wash the coconut dregs with 1 times the hot water at 90°C and then separate, and the separated coconut dregs are refined to obtain coconut edible cellulose; twice the filtrate Merge, use a centrifugal machine to act under the condition of 8000r / min for 15min, the upper layer is emulsified coconut oil, and the lower layer is coconut protein liquid; after the emulsified coconut oil is demulsified, separated and dried, pure coconut oil is obtained, and the coconut protein liquid is processed by ultrafiltration membrane And after vacuum concentration, spray drying becomes coconut protein powder. ...

Embodiment 2

[0012] After 50Kg of white coconut meat is crushed, it is ground together with 135 liters of buffer solution; 0.50Kg of compound enzyme is added, and the compound enzyme is composed of pectinase, amylase and protease in a mass ratio of 45:25:30, and is enzymolyzed at 50°C Extract for 5 hours; raise the temperature to 90°C and keep it for 10 minutes, and use a filter press to separate the solid and liquid; wash the coconut dregs with 1 times the hot water at 90°C and then separate, and the separated coconut dregs are refined to obtain coconut edible cellulose; the two filtrates are combined , use a centrifugal machine to act under the condition of 10000r / min for 10min, the upper layer is emulsified coconut oil, and the lower layer is coconut protein liquid; after the emulsified coconut oil is demulsified, separated and dried, pure coconut oil is obtained, and the coconut protein liquid is processed by ultrafiltration membrane and After vacuum concentration, it is spray-dried to ...

Embodiment 3

[0014] After 50Kg of white coconut meat is crushed, it is ground together with 210 liters of buffer solution; 0.45Kg of compound enzyme is added, and the compound enzyme is composed of pectinase, amylase and protease in a mass ratio of 55:35:30, and is enzymolyzed at 60°C Leach for 3.5 hours; heat up to 90°C and keep for 10 minutes, and use a filter press to separate the solid and liquid; wash the coconut dregs with 1 times the hot water at 90°C and then separate, and the separated coconut dregs are refined to obtain coconut edible cellulose; twice the filtrate Merge, use a centrifugal machine to act under the condition of 10000r / min for 10min, the upper layer is emulsified coconut oil, and the lower layer is coconut protein liquid; after the emulsified coconut oil is demulsified, separated and dried, pure coconut oil is obtained, and the coconut protein liquid is processed by ultrafiltration membrane And after vacuum concentration, spray drying becomes coconut protein powder. ...

Abstract

The invention relates to a method for extracting coconut oil and byproducts from fresh coconut pulp, which comprises the following steps: peeling and crushing shells of coconuts to obtain fresh whitecoconut pulp, crushing the fresh white coconut pulp and grinding the fresh white coconut pulp and buffer solution, then adding enzyme into the mixture to carry out extraction, filter-pressing the extract, separating dietary coconut fibers and the filtrate, centrifugating the filtrate, and separating emulsified coconut oil and coconut protein solution so as to obtain the coconut oil and coconut protein powder respectively. The coconut oil processed by the method has fresh character and can be directly eaten or applied, and the byproducts comprising the dietary coconut fibers and the coconut protein powder can be used as food accessories or additives, so the method improves the utilization level of the coconut pulp and the extraction rate of the coconut oil, and has high economic benefit andgood application prospect.

Description

1. Technical field [0001] The invention relates to a method for extracting coconut oil and by-products from fresh coconut meat. 2. Background technology [0002] Making full use of the coconut meat resource and making the best use of it is one of the hotspots of people's research. The traditional production method of coconut oil is: make coconut meat into copra, crush and heat it, and use a press to extract coconut oil. The squeezed coconut oil has more impurities and needs to be processed before it can be used. The remaining oil cake is used as feed or fertilizer. . The production method of traditional coconut oil has a long process and a large loss, and coconut protein and coconut meat cellulose cannot be fully utilized, resulting in a great waste of coconut meat resources. [0003] For overcoming above-mentioned shortcoming, improve coconut meat comprehensive utilization level, the present invention proposes a kind of method directly extracting coconut oil and by-produc...
