Problems solved by technology

[0002] There are many kinds of rapeseed oil on the market, but the existing rapeseed planting and rapeseed oil processing methods are often harvested after maturity, and then a lot of nutrients are removed during processing to improve the storage time of the oil, which makes rapeseed The chlorophyll in the oil is decomposed and lost to a large extent, which greatly reduces the chlorophyll content of rapeseed oil itself

Embodiment 1

[0022] A processing method for chlorophyll rapeseed oil, comprising the following steps:

[0023] S1. Harvesting the rapeseed 6 days before it matures to obtain the rapeseed, and then air-drying the rapeseed at a temperature of 20°C until the moisture content reaches 4%;

[0024] S2, the air-dried rapeseed is heated by high-temperature steam at a temperature of 200° C. for 5 minutes, and then rinsed once with cold water at 0° C.;

[0025] S3, the rapeseed after washing once again is heated by high-temperature steam at a temperature of 250° C. for 3 minutes, and then washed with cold water at 0° C. for the second time;

[0026] S4, adding the rapeseed after secondary washing into the oil press to extract rapeseed oil, the extraction temperature is 60°C to obtain primary rapeseed oil;

[0027] S5. The obtained primary rapeseed oil is subjected to primary filtration, static precipitation, secondary filtration and degassing in sequence to obtain the chlorophyll rapeseed oil.

Abstract

A processing method of chlorophyll-bearing rapeseed oil comprises the steps of S1, reaping 6-10 days before rape is mature to obtain rapeseed, and air-drying at 20-30 DEG C until water content reaches4-6%; S2, heating through high-temperature steam for 5-8 min, and flushing for the first time with cold water with the temperature of 0-5 DEG C; S3, heating again through high-temperature steam for 3-5 min, and flushing for the second time with cold water; S4, adding the rapeseed flushed secondarily into an oil press to press rapeseed oil at 60-80 DEG C so as to obtain primary rapeseed oil; S5, filtering the primary rapeseed oil firstly, allowing to stand and precipitate, filtering secondarily, and degassing to obtain the chlorophyll-bearing rapeseed oil. The processing method herein enablesdecomposition loss rate of chlorophyll-bearing rapeseed oil in wheat kernels to be effectively decreased; each kg of the finally attained chlorophyll-bearing rapeseed oil has the chlorophyll content of up to 64-106 mg, and eating value of the rapeseed oil itself is greatly improved.

Description

technical field [0001] The invention relates to the field of grain and oil processing, in particular to a processing method of chlorophyll rapeseed oil. Background technique [0002] There are many kinds of rapeseed oil on the market, but the existing rapeseed planting and rapeseed oil processing methods are often harvested after maturity, and then a lot of nutrients are removed during processing to improve the storage time of the oil, which makes rapeseed The chlorophyll in the oil is decomposed and lost to a large extent, which greatly reduces the chlorophyll content of rapeseed oil itself. Contents of the invention [0003] Aiming at the deficiencies in the above technologies, the present invention provides a method that can greatly reduce the decomposition and loss of chlorophyll contained in rapeseed oil itself, thereby increasing the chlorophyll content of rapeseed oil. [0004] A processing method for chlorophyll rapeseed oil, comprising the following steps: [00...
