Problems solved by technology

However, supercritical CO 2 Due to the expensive equipment investment and maintenance costs brought about by high pressure, fluid extraction is unable to be used by small and medium-sized enterprises; at the same time, the enzyme preparations used for enzymatic hydrolysis are expensive, so they cannot be widely used, so it is forced to engage in deep processing of agricultural and forestry products. Workers must concentrate on low investment, low cost, quick effect, simple process, strong operability, low energy consumption, low emission, and green technology research

Abstract

The invention discloses a method for extracting suaeda salsa seed oil by adopting deionized water. The method is operated according to the following steps: 1) grinding, namely grinding suaeda salsa seeds into 60-150 meshes; 2) soaking, namely fully mixing the uniformly-grinded suaeda salsa seed powder with deionized water by a material liquid weight-to-volume ratio of 1:3-1:10, and soaking; 3) pH regulation, namely regulating the pH value to 4.0-6.0; 4) catalytic pyrolysis, namely putting a solid and liquid mixture of which the pH value is regulated into a water bath at 40-65 degrees centigrade for catalytic pyrolysis for 1-5 hours; and 5) centrifugation. After the catalytic pyrolysis reaction, the solid and liquid mixture is centrifuged at a rotating speed of 4000-10000 rpm / min for 10-30 minutes; a centrifuged supernatant oil layer is sucked out, and then the required suaeda salsa seed oil is obtained. The method disclosed by the invention has the advantages of high oil yield, good quality, simple and safe process, high operability and low cost.

Description

technical field [0001] The invention relates to the technical field of vegetable oil production, and relates to a technical method for developing high-quality health-care and edible oils using Suaeda salsa seed oil, in particular to a deionized water extraction method for Suaeda salsa seed oil. Background technique [0002] Suaeda salsa, also known as Artemisia salsa, seafood dish, Suaeda (Suaeda) is an annual herb true halophyte of Chenopodiaceae (Chenopodiaceae). Saline-alkaline deserts and semi-deserts such as coastal and lakesides, shallow flat depressions, or coastal tidal flats and other saline swamp environments. In addition, Suaeda salsa can absorb a large amount of soluble salts from the soil, significantly increase the total porosity of the soil, reduce soil bulk density, increase soil organic matter, alkaline nitrogen, available phosphorus, available potassium, and soil bacteria, actinomycetes, and fungi. It has obvious bioremediation effect on saline soil. [0...
