Embodiment 1

[0025] A high extraction rate octacosanol extraction process in seawater rice, comprising the following steps:

[0026] (1) Seawater rice is screened to remove bad grains and shriveled grains in seawater rice;

[0027] (2) Place the seawater rice treated in step (1) in a constant temperature room for 3 hours, and then add the seawater rice to the alginate soaking solution. The mixing ratio of seawater rice and alginate soaking solution is 250g:400mL. Place it at 38°C for 38 hours, take it out after all the seawater rice germinates, and obtain germinated seawater rice. The temperature inside the thermostatic chamber is 30°C, and the relative air humidity is 70%. Sodium sodium, glucose, vitamin C, potassium chloride, magnesium stearate, and water are mixed in a mass ratio of 12:3:3:1:5:4:85, and the alginate is sodium alginate;

Abstract

The invention discloses a high-extraction-rate octacosanol extraction process for sea rice. The high-extraction-rate octacosanol extraction process comprises the following steps: (1) screening sea rice; (2) obtaining germinated seawater rice; (3) obtaining sea rice flour; (4) obtaining an enzyme treatment solution; (5) obtaining an enzyme treatment product; and (6) adding an alkali solution into the enzymolysis product, uniformly stirring, carrying out ultrasonic treatment, carrying out dipping treatment to obtain an alkali treatment solution, extracting for three times by adopting an ethanol-acetone mixed solvent of which the volume is 3 times that of the alkali treatment solution, mixing extract solutions, and carrying out vacuum rectification to obtain the product. The octacosanol in the sea rice is extracted by the process, so that the extraction rate and the purity can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of seawater rice processing, and in particular relates to a process for extracting octacosanol with high extraction rate from seawater rice. Background technique [0002] Seawater rice is a popular term for salt-resistant rice, which is between wild rice and cultivated rice. It looks like a reed, but it bears ears. Its plants are tall, loose in shape, thick in stems, lush in growth, and small in grains. Moreover, seawater rice has the ability to resist waterlogging, saline-alkali, lodging, and pests. Octacosanol is a chain saturated monohydric alcohol containing 28 carbon atoms. It exists widely in nature, mainly in the form of higher fatty acid wax esters, and rarely in free form. Octacosanol prepared from natural higher fatty acid esters contains short-chain alcohols and impurities other than alcohols, and the presence of impurities has a greater impact on the physiological activity of octacosanol. The...
