Embodiment 1

[0039] The specific steps of a method for preparing hydrolyzed oligosaccharides and short peptides from salina are as follows:

[0040] (1) Separation of salina residue

[0041] With the salina slag powder that extracts β-carotene as raw material, by the weight (gram) of salina slag powder: the volume (liter) ratio of deionized water is the ratio of 1:5, first adds deionized water in the container, Then add the salt algae residue powder, stir until the salt algae residue powder is evenly dispersed, then use ultrasonic treatment for 30 minutes, and then centrifuge at a speed of 10,000 rpm for 5 minutes to collect the lower sediment and supernatant respectively. The collected lower precipitate is used to prepare hydrolyzed salina peptide, and the collected supernatant is separated by ultrafiltration with an ultrafilter with a molecular weight cut-off of 5KDa, and then the ultrafiltrate and the intercepted concentrate are collected separately. The filtrate contains small Molecul...

Abstract

The invention provides a method for preparing hydrolyzed oligosaccharides and short peptides from salt algae residues, which belongs to the technical field of salt algae utilization. The method adopts beta-carotene removed salt algae residues as raw materials, separation and enzymatic hydrolysis are repeatedly performed, and then various products are made after concentration and drying. The method provided by the invention comprehensively utilizes the salt algae residues to make various daily use chemicals, medicines and health products, such as skin energy activating solution, hydrolyzed salt algae oligosaccharides and polysaccharide and short peptides. The residue and precipitate of the hydrolyzed salt algae is retained, but not discarded during production process, and then is used as fermentation base material for microbial fertilizer preparation. The products prepared through the method can be wildly applied to products for skin care, moisture preservation, nutrition, antioxidation and anti-ageing, can be applied to health products and anti-tumor products, and also can be served as single cell protein products to complement nitrogen nutrition and radioprotective products.

Description

1. Technical field [0001] The invention belongs to the technical field of salina utilization, and in particular relates to a method for preparing salhalose and short peptides from salina residues from which beta-carotene has been removed. 2. Background technology [0002] Salina, also known as salina, is a green single-celled algae with a tiny shape and a coating formed by glycoproteins. It is mainly distributed in coastal waters, and its adaptability to salinity ranges from 0.2 to 3.5%. It has the characteristics of fast reproduction, strong viability, and suitable for breeding. my country has a long coastline and a large number of inland salt lakes suitable for the survival of salina, so salina is widely distributed and rich in resources. Salina is rich in oil, β-carotene, protein, polysaccharide compounds, Ca, P, Zn and other trace minerals, including 8 kinds of amino acids necessary for human beings and other series of available substances. At present, Inner Mongolia J...
