Embodiment 1

[0074] The first step, washing vegetables: 1.5 tons of seaweed or asparagus, prepare 15 tons of NaOH solution with a percentage content of 7%, and heat the sodium hydroxide solution to 80 ° C, pour the heated sodium hydroxide solution into the Soak in a vegetable washing tank containing 1.5 tons of vegetables for 2-4 hours at a constant temperature;

[0075] The second step, alkali treatment: after soaking, pump the NaOH solution into the heating tank, add water to spray the vegetable body, make the total amount of NaOH solution about 14 tons, and then add an appropriate amount of 30% liquid alkali to increase the alkali content of the lye. 3-10%, at the same time add 0.05% anthracene derivatives by weight of algae to increase the yield of agar;

[0076] The third step, water washing: soak in tap water for 2 hours for the first wash and discharge, soak for 4 hours in tap water for the second wash and discharge, soak in tap water for 6 hours in the third, fourth, and fifth wash...

Embodiment 2

[0100] The difference from Example 1 is that in the first step, 15 tons of 11% NaOH solution is prepared and heated to 90°C.

Embodiment 3

[0102] The difference from Example 1 is that the fourth step of acid bleaching treatment: after washing, add hydrochloric acid and sulfamic acid salt, add an available chlorine content of 0.1% sodium hypochlorite solution, adjust the pH value to 4, and perform a bleaching. After 30 minutes, add 0.01% potassium permanganate and oxalic acid, adjust the pH value to 5, and perform secondary bleaching. After 20-30 minutes, wash again until neutral;

Abstract

The invention discloses a method for extracting agar from nori and asparagus, and belongs to the technical field of marine organism deep processing. The agar is extracted from raw materials includingnori or asparagus. The extraction method comprises the following steps: carrying out preprocessing, alkali processing, washing and acid bleaching processing on the nori or the asparagus, extracting refined filtration glue solution, and carrying out condensation and ageing and the like on the refined filtration glue solution. Anthracene derivatives are added in the alkali processing step, so that the reductive end group of agar molecules becomes stable, an agar degradation phenomenon caused by traditional high-temperature processing is weakened, and the yield of the agar is improved by 3%. In first bleaching, sulfamate can be added to weaken the oxidation of sodium hypochlorite for the agar molecules, and the gel intensity of the agar is improved by 300g / cm<2> or more. The extracted agar product is characterized in that the production cost of the agar product is lower than that of the similar product in the traditional market while the agar product has the advantages of quality and price, and the agar product more caters to the market.

Description

technical field [0001] The invention relates to the technical field of deep processing of marine organisms, in particular to a method for extracting agar from laver and asparagus. Background technique [0002] At present, the domestic seaweed processing industry has problems such as few types of products, low quality grades, poor ability to extend to high value-added products, labor-intensive production and processing, high intensity, and high water consumption. Development of high-value and refined seaweed processing technologies and products , huge potential and broad market prospects. Agar is a polymer polysaccharide with excellent coagulation properties. It has the functions of detoxification and beautification, lowering blood pressure, lowering blood sugar, and improving immunity. It is widely used in food, medicine, agriculture and scientific research. With the development of science and technology, the artificial breeding technology is becoming more and more mature. ...
