Embodiment 1

[0025] Example 1: Weigh 10 grams of microwave puffed pretreated safflower camellia seed kernel dregs, add 50 ml of water, stir at room temperature for 1 hour, and separate the oil layer After mixing with the water layer, add water to the residue, adjust the pH to 6-7 with hydrochloric acid solution, add 2% neutral protease, enzymatically hydrolyze at 55°C for 3 hours, and separate the oil layer , to merge oil layers and oil layer , 5.4 grams of Mao-camellia oil can be obtained.

Embodiment 2

[0026] Example 2: Weigh 10 grams of microwave puffed pretreated safflower camellia seed kernel dregs, add 100 ml of hot water, stir for 1 hour, and separate the oil layer After mixing with the water layer, add water to the residue, add 2% alkaline protease (Alcalase 2.4L), enzymatically hydrolyze at 55°C for 3 hours, and separate the oil layer , to merge oil layers and oil layer , 5.5 grams of Mao-camellia oil can be obtained.

[0027] The invention adopts microwave puffing to pretreat raw materials such as camellia seed kernels, which can fully destroy the cell structure of raw materials, and is beneficial to improve the oil yield of oil extraction by subsequent water immersion method; the oil extracted by water after microwave pretreatment belongs to a green and safe production process ; The present invention has the characteristics of simple and environmentally friendly technological process, high oil yield, low investment and easy industrial production.

Abstract

The invention relates to a method for digesting grease through microwave pretreatment and an aqueous enzymatic method. The method includes soaking raw materials, performing microwave puffing treatment on camellia oleifera seed slurry, digesting grease with water, performing physical refining on the obtained grease after degumming through a phosphatidase enzymatic method, or directly performing rough filtration, refined filtration and nanofiltration, and then performing vacuum dehydration and drying to obtain grease products and a by-product of wet meal. According to the method, the microwave puffing treatment is adopted on raw materials such as camellia oleifera seeds, cell structures of the raw materials can be fully destroyed, and the oil yield of the following water immersion method can be improved; grease digestion through water after microwave pretreatment for materials belongs to an environment-friendly and safe production process; and the method has the advantages of being simple and environment-friendly in process, high in oil yield, low in investment and prone to industrial production.

Description

technical field [0001] The invention belongs to the technical field of deep processing of agricultural and forestry by-products, and relates to the application of microwave puffing technology in the processing of tea oil, sesame oil, rapeseed oil, silkworm chrysalis, etc., and specifically refers to a method for microwave pretreatment and enzymatic extraction of oil. Background technique [0002] Oil production enterprises generally adopt pressing method or leaching method to produce, and the quality of oil obtained by this process is poor. In order to obtain high-quality oil, patents CN200610031893.1 and CN200810059993.4 used acid protease, cellulase, amylase, etc. to extract camellia seed oil by aqueous enzymatic method; patent CN201010284737.2 prepared shellfish viscera oil by aqueous enzymatic method; Patent water enzymatic extraction of pumpkin seed oil; patent 200610031452.1 using physical low-temperature cold pressing technology to produce tea seed oil; patent CN20111...
