Problems solved by technology

[0004] Eucheuma is mainly produced on islands and reefs such as Hainan and Nansha and the coasts of Southeast Asian countries. It is rich in alginate, cellulose, hemicellulose, vitamins and minerals. At present, Eucheuma is mainly used to produce carrageenan, but carrageenan products Oversupply, unsalable products, falling prices, and poor profitability of production enterprises; resulting in a waste of Eucheuma resources

Embodiment 1

[0018] Pretreat Eucheuma, remove impurities, clean it, use 10% sodium hydroxide solution, the general dosage is 13 times the weight of Eucheuma, soak Eucheuma, stir evenly, and treat it at room temperature for 22 hours; remove Eucheuma , the lye can be used for the alkali treatment of the next batch of raw materials, if the concentration of the alkali is not enough, add alkali. The Eucheuma taken out is fully washed with water to be close to neutral, and then the Eucheuma algae after the alkali treatment is bleached with 0.2% sodium hypochlorite. The pH of the sodium hypochlorite is 4.2, and the amount of bleaching solution is 10 times the weight of the above-mentioned Eucheuma pulled out. After 30 minutes, the bleaching solution was drained, and the Eucheuma algae were fully washed to neutral again, placed in a centrifuge for centrifugal dehydration, vacuum-dried with a vacuum dryer at 50°C, and then pulverized by an ultrafine pulverizer to 70-mesh powder, then add an embeddi...

Embodiment 2

[0020] Pretreat Eucheuma, remove impurities, clean it, use 5% sodium hydroxide solution, the general dosage is 15 times the weight of Eucheuma, soak Eucheuma, stir evenly, and treat it at room temperature for 24 hours; remove Eucheuma Fully wash with water to be close to neutrality, then bleach the Eucheuma algae after alkali treatment with 0.1% sodium hypochlorite, the pH of sodium hypochlorite is 4.5, the amount of bleaching solution is 12 times the weight of the above-mentioned Eucheuma, bleach for 40 minutes, drain For bleaching solution, wash Eucheuma algae fully with water to neutral again, put it in a centrifuge for centrifugal dehydration, vacuum dry it with a vacuum dryer at 50°C, and then pulverize it into a 60-mesh powder with an ultrafine pulverizer , and then add an embedding agent mixed with 3% calcium lactate and 0.5% vitamin C, stir evenly and package the finished product, which is the Eucheuma high active dietary fiber.

Embodiment 3

[0022] Pretreat Eucheuma, remove impurities, clean it, use 15% sodium hydroxide solution, the general dosage is 12 times the weight of Eucheuma, soak Eucheuma, stir evenly, and treat it at room temperature for 20 hours; remove Eucheuma , the lye can be used for the alkali treatment of the next batch of raw materials, if the concentration of the alkali is not enough, add alkali. The Eucheuma taken out is fully washed with water close to neutrality, and then the Eucheuma algae after the alkali treatment is bleached with 0.3% sodium hypochlorite. The pH of the sodium hypochlorite is 4, and the amount of bleaching solution is 8 times the weight of the above-mentioned Eucheuma pulled out. After 20 minutes, the bleaching solution was drained, and the Eucheuma algae were fully washed to neutral again, placed in a centrifuge for centrifugal dehydration, vacuum-dried with a vacuum dryer at 50°C, and then pulverized by an ultrafine pulverizer to 80-mesh powder, then add an embedding age...

Abstract

The production process of extracting food fiber from muriculate eucheuma frond includes the following steps: alkali solution soaking treatment of washed muriculate eucheuma frond at normal for 20-24 hr; water washing to neutral and bleaching in bleaching liuqid for 20-40 min; water washing to neutral, centrifugal dewatering, vacuum drying and crushing to obtain food fiber powder. The present invention raises the utilization value and opens the way of utilizing muriculate eucheuma frond in food.

Description

Technical field [0001] The invention relates to a production process for extracting dietary fiber, in particular to a production process for extracting dietary fiber from Eucheuma. Background technique [0002] Dietary fiber is a kind of non-starch polysaccharide. According to solubility, dietary fiber can be divided into two types: water-insoluble and water-soluble. Water-insoluble dietary fiber is a component of cell walls, including cellulose, hemicellulose, lignin, and chitosan; water-soluble dietary fiber refers to storage substances and secretions in plant cell walls, and also includes some microbial polysaccharides and synthetic Polysaccharides, such as pectin, guar gum, alginate, CMC and fungal polysaccharides. [0003] Dietary fiber is called the "seventh nutrient" by medical and nutritionists. It has been proved by experiments that it has many important physiological functions for human health: (1) It softens the stool and increases the excretion of stool, which c...
