Problems solved by technology

After the rapeseed is dehulled, the physical properties of the material, such as friction coefficient and permeability, will change greatly, which is not conducive to oil extraction; secondly, when the dehulled rapeseed kernel is cold-pressed, the oil entering the machine is not subjected to any heating and rolling. Billet and other pretreatments, the degree of cell wall damage is small, and the affinity between liposomes and proteins is still strong, which is not conducive to oil extraction

Embodiment 1

[0026] A pressing process for regulating the fat ratio of rapeseed oil comprises the following steps:

[0027] 1) Dry the rapeseed until the water content is 10%, put it into an extrusion extruder and extrude to obtain oil, and the rapeseed is extruded to form pellets;

[0028] 2) Add the granules obtained in step 1) into water, add 2mL of water per 1g of granules, heat up to 25°C, add compound enzymes (cellulase, pectinase and protease in a mass ratio of 1: 1:1 compound), stirred and reacted at 120rpm for 1h; raised the temperature to 100°C, inactivated the enzyme for 5min, filtered, and collected the filter residue;

[0029] 3) Add water to the filter residue in step 2) for leaching, add 3mL of water per 1g of filter residue, raise the temperature to 50°C, stir for 1h, then centrifuge (12000rpm) to separate oil, waste water and solid phase precipitation, and mix the obtained oil with The fats and oils in step 1) are combined to obtain fats and oils. The yield is 82%, and t...

[0031] A pressing process for regulating the fat ratio of rapeseed oil comprises the following steps:

[0032] 1) Dry the rapeseed to a moisture content of 12%, add it to an extrusion extruder and extrude to obtain oil, and the rapeseed is extruded to form pellets;

[0033] 2) Add the granules obtained in step 1) into water, add 5mL of water per 1g of granules, raise the temperature to 30°C, add compound enzymes (cellulase, pectinase and protease in a mass ratio of 5:1:8 to compound made), stirred at a speed of 130rpm for 2h; heated to 100°C, inactivated the enzyme for 5min, filtered, and collected the filter residue;

[0034] 3) Add water to the filter residue in step 2) for leaching, add 5mL of water per 1g of filter residue, raise the temperature to 60°C, stir for 2h, and then centrifuge (15000rpm) to separate oil, waste water and solid phase precipitation, and mix the obtained oil with The fats and oils in step 1) are combined to obtain fats and oils. The yield is 91%, a...

Embodiment 3

[0036] A pressing process for regulating the fat ratio of rapeseed oil comprises the following steps:

[0037] 1) Dry the rapeseed to a moisture content of 8%, add it to an extruder for extrusion, and extrude to obtain oil, and the rapeseed is extruded to form pellets;

[0038] 2) Add the granules obtained in step 1) into water, add 3mL of water per 1g of granules, raise the temperature to 40°C, add compound enzymes (cellulase, pectinase and protease in a mass ratio of 6:1:3 to compound made), stirred at a speed of 130rpm for 2h; heated to 90°C, inactivated the enzyme for 10min, filtered, and collected the filter residue;

[0039] 3) Add water to the filter residue in step 2) for leaching, add 3mL of water per 1g of filter residue, raise the temperature to 60°C, stir for 2h, and then centrifuge (18000rpm) to separate oil, waste water and solid phase precipitation, and mix the obtained oil with The fats and oils in step 1) are combined to obtain fats and oils. The yield is 88...

Abstract

The invention discloses an extracting process regulating grease ratio of colza oil, comprising: drying the water content of rapeseed to 5-15%, adding into an extruding bulking machine to extrude grease, and forming the rapeseed into grains; adding the grains into water, heating, adding composite enzyme, and stirring for reaction; heating to destroy the enzyme, filtering, and collecting filter slag; adding water into the filter slag for leaching, heating and stirring, then centrifuging to separate oil, sewage and solid sediment; combining obtained oil with the grease in step (1) to obtain grease. By controlling the water content of the rapeseed and extracting process parameters, the process improves the ratio of linoleic acid to linolenic acid in the grease obtained by extruding, and improves nutrient value of the grease. According to the extracting process, the rapeseed is not required to be peeled, no organic solvent is adopted in the whole process, the obtained grease is safe, and a process route is green and environment-friendly and high in grease yield.

Description

technical field [0001] The invention belongs to the technical field of rapeseed oil processing, and in particular relates to a pressing process for regulating the fat ratio of rapeseed oil. Background technique [0002] Rapeseed has become one of the important oil crops in the world and our country because of its rich oil and amino acid composition of excellent protein. According to the statistics of FAO (2002), among the oil crops in the world, the output of rapeseed ranks fourth after soybean, palm and cottonseed. my country's rapeseed planting area and output are currently ranking first in the world. In order to make full use of rapeseed, a high-quality resource, countries all over the world have carried out extensive and in-depth research on the high-efficiency processing and utilization of rapeseed. [0003] Rapeseed dehulling and cold-pressing technology is still the focus of research in various countries in the world. At present, the dehulling technology has been ...
