Embodiment 1

[0030] Example 1: Extracting L-citrulline from watermelon

[0031] 1. Slicing: After washing 20 tons of watermelon with water, chop it with a watermelon chopper.

[0032] 2. Separation of skin and pulp: Use glue stick soft separator and two separation units to perform primary and secondary separation to completely separate watermelon rind and watermelon pulp.

[0033] 3. Juicing: About 6 tons of watermelon rinds are squeezed with a belt press or a plate and frame filter press to collect the juice of the melon rinds. The dried and pulverized melon rind fiber can be used in the production of watermelon fiber oral preparations.

[0034] 4. Separation: about 14 tons of watermelon pulp pass through the seed juice separator (the watermelon seed and watermelon pulp fiber and watermelon pulp juice separation machine effect is better with the watermelon pulp fiber and watermelon pulp juice developed by Xinjiang Machinery Research Institute), so that the watermelon pulp fiber, watermel...

Embodiment 2

[0056] Embodiment two: take watermelon as raw material to extract L-citrulline

[0057] 1. Slicing: After washing 20 tons of watermelon with water, chop it with a watermelon chopper.

[0058] 2. Separation of skin and pulp: Use glue stick soft separator and two separation units to perform primary and secondary separation to completely separate watermelon rind and watermelon pulp.

[0059] 3. Juicing: About 6 tons of watermelon rinds are squeezed with a belt press or a plate and frame filter press to collect the juice of the melon rinds. The dried and pulverized melon rind fiber can be used in the production of watermelon fiber oral preparations.

[0060] 4. Separation: about 14 tons of watermelon pulp pass through the seed juice separator (the watermelon seed and watermelon pulp fiber and watermelon pulp juice separation machine effect is better with the watermelon pulp fiber and watermelon pulp juice developed by Xinjiang Machinery Research Institute), so that the watermelon...

[0071] Example three: Extracting L-citrulline from watermelon

[0072] 1. Slicing: After washing 20 tons of watermelon with water, chop it with a watermelon chopper.

[0073] 2. Separation of skin and pulp: Use glue stick soft separator and two separation units to perform primary and secondary separation to completely separate watermelon rind and watermelon pulp.

[0074] 3. Juicing: About 6 tons of watermelon rinds are squeezed with a belt press or a plate and frame filter press to collect the juice of the melon rinds. The dried and pulverized melon rind fiber can be used in the production of watermelon fiber oral preparations.

[0075] 4. Separation: about 14 tons of watermelon pulp pass through the seed juice separator (the watermelon seed and watermelon pulp fiber and watermelon pulp juice separation machine effect is better with the watermelon pulp fiber and watermelon pulp juice developed by Xinjiang Machinery Research Institute), so that the watermelon pulp fiber, wate...

Abstract

The invention provides an industrial method for extracting natural L-citrulline from plant tissues of watermelons or citrullus lamatus, and the like, which belongs to the technical field of extracting natural products in the food industry and the medicine industry. The watermelons, the citrullus lamtus or the stems and leaves thereof are taken as raw materials, and the extracting process comprises the following steps: firstly, the raw materials are washed clean and broken to separate the watermelon peel from the watermelon pulp for respectively extracting juice; the two juices are mixed, and micro-filtration and ultra-filtration are carried out to remove insoluble substances and macromolecular substances; and then reverse osmosis and nano-filtration are carried out to obtain the filtrate;the pH value of the filtrate is regulated and then a macroporous strong acid cation exchange resin column is added; and then ammonia water is taken as an eluant for isocratic elution; the eluent obtained is decompressed, distilled, deaminized, discolored, condensed and crystallized to obtain a white crystalline product of the natural L-citrulline extracted from the watermelons. The prepared product is a pure natural product without harmful substances and has high purity and good quality, thus the natural L-citrulline can be directly taken as a food additive and raw material of health productsor medicines.

Description

technical field [0001] The present invention relates to a natural product extraction technology in the field of food and medicine, especially a kind of plant cell tissue with high citrulline content formed by watermelon, melon, and its neck leaves, or cell tissue culture without any chemical reaction. As a raw material, an industrial process for the production of high-purity natural L-citrulline products. Background technique [0002] Citrulline, first found in wild watermelon leaves, is a non-essential amino acid. L-citrulline has a strong antioxidant effect and can effectively remove free radicals in the human body. L-citrulline in watermelon is known as "green Viagra", which can effectively increase male libido, promote male reproductive capacity, and maintain normal male reproductive health. Citrulline also has a vasodilator effect and has a good health care effect on the cardiovascular system. In addition, citrulline can effectively improve the anti-fatigue ability o...
