Problems solved by technology

However, okra has only been cultivated in a small amount in various parts of the country since it was introduced into my country in the early 1990s, and it has not been widely promoted, nor has it formed an industrialized operation.
At present, okra products are mainly exported to fresh vegetables, the product type is single, the level of deep processing is low, the added value is low, and it has not been able to play its due value. Therefore, it is of great significance to speed up the development of okra health products and the research on processing technology and technology. There will be huge social and economic benefits

Embodiment 1

[0018] 1000g okra fresh fruit, add 10L of water, pulverize with tissue pulverizer, add the compound enzyme extraction that compound mass ratio is cellulase: helicase: lysozyme: neutral protease Neutrase=3:1:0.5:4, and the amount of enzyme added is 5g. The enzymolysis extraction conditions are pH6.5; the temperature is 30°C; the extraction time is 6h. After the extraction is completed, the large particle residue is removed by centrifugation, and then suction-filtered to obtain an aqueous solution of okra polysaccharide. Add maltodextrin to the okra polysaccharide aqueous solution. The amount of maltodextrin added is 10% of the dry matter of the okra polysaccharide aqueous solution. After the maltodextrin is added, high-pressure homogenization is performed. The homogenization pressure is 16 MP, and the homogenization cycle is 4 times. The homogenized solution is spray-dried, the air inlet temperature is 160-200°C, and the air outlet temperature is 80-100°C to obtain dry okra po...

Embodiment 2

[0020] 1000g okra fresh fruit, add 30L of water, pulverize with tissue pulverizer, add the compound enzyme extraction that compound mass ratio is cellulase: helicase: lysozyme: neutral protease Neutrase=3:1:0.5:4, and the amount of enzyme added is 30g. The enzymolysis extraction conditions are pH7.0; the temperature is 40°C; the extraction time is 8h. After the extraction is completed, the large particle residue is removed by centrifugation, and then suction-filtered to obtain an aqueous solution of okra polysaccharide. Add maltodextrin to the okra polysaccharide aqueous solution. The amount of maltodextrin added is 35% of the dry matter of the okra polysaccharide aqueous solution. After the maltodextrin is added, high-pressure homogenization is performed. The homogenization pressure is 25 MP, and the homogenization cycle is 8 times. The homogenized solution is spray-dried, the air inlet temperature is 160-200°C, and the air outlet temperature is 80-100°C to obtain dry okra p...

Embodiment 3

[0022] Add 60 L of water to 1000 g of fresh okra fruit, pulverize with a tissue grinder, extract with compound enzyme, and the amount of enzyme added is 25 g. The enzymolysis extraction conditions are pH7.5; the temperature is 40°C; the extraction time is 7h. After the extraction is completed, the large particle residue is removed by centrifugation, and then suction-filtered to obtain an aqueous solution of okra polysaccharide. Add maltodextrin to the okra polysaccharide aqueous solution. The amount of maltodextrin added is 20% of the dry matter of the okra polysaccharide aqueous solution. After the maltodextrin is added, high-pressure homogenization is carried out. The homogenization pressure is 20 MP, and the homogenization cycle is 6 times. The homogenized solution is spray-dried, the air inlet temperature is 160-200°C, and the air outlet temperature is 80-100°C to obtain dry okra polysaccharide powder. The dry okra polysaccharide powder has a water content of ≤5% and a sol...

Abstract

The invention belongs to the technical field of functional foodstuff engineering, and relates to a preparation method of abelmoschs esculentus water-soluble polysaccharide spray-dried powder. The method comprises steps that: water is added to an abelmoschs esculentus raw material, and the mixture is crushed by using a tissue crusher; compound enzyme is added to the abelmoschs esculentus crushed solution, and the solution is extracted; under an appropriate condition, the solution is processed through enzymolysis extraction; large-particle residues in the extract obtained by enzymolysis extraction are removed by centrifugation with a rotary rate of 4000r / min; the obtained extract is processed through vacuum filtration, such that an abelmoschs esculentus polysaccharide aqueous solution is obtained; maltodextrin is added to the abelmoschs esculentus polysaccharide aqueous solution, wherein the added amount of maltodextrin takes 10%-35% of the mass of dry substances of the abelmoschs esculentus polysaccharide aqueous solution; after maltodextrin is added, high-pressure homogenization is carried out under a homogenization pressure of 16-25MP, and homogenization circulation is carried out for 4-10 times; the homogenized solution is spray-dried with an intake air temperature of 160-200 DEG C and an discharged air temperature of 80-100 DEG C, such that the abelmoschs esculentus polysaccharide dry powder is obtained. According to the invention, utilization rate of abelmoschs esculentus is high, and the dissolubility of the soluble polysaccharide in water is high.

Description

technical field [0001] The invention belongs to the technical field of functional food engineering, and in particular relates to a production method of a functional food component-water-soluble polysaccharide. Background technique [0002] Okra [Abelmoschus esculentus (L.) M oench], also known as okra abroad, is a species of the genus Okra in the Malvaceae family and is an annual herb. Widely distributed in tropical to subtropical regions. There are many names in our country, also known as croissant, foreign sesame, hair eggplant, kidney tonifying grass and so on. According to "Compendium of Materia Medica" and other ancient books, the roots, stems, flowers, and seeds of okra can be used as medicine. Its nature and flavor are sweet, cold, and slippery. Dry constipation and malignant sores, carbuncle furuncle and other diseases. Modern pharmacological studies have proved that polysaccharides are the main functional components of okra, which have health functions such as an...
