Embodiment 1

[0032] Take 2 g of Suaeda salsa filter residue in a 100 mL round-bottomed flask, add 30 mL of pure water, mix well, adjust the pH to 9, 10, 11, 12, and 13, and place it in a 60°C water bath for 60 min. Collect the treated solution, add 5 times the volume of 95% ethanol, ethanol precipitation for 4 h, centrifuge at 5000 r / min for 15 min, and measure the extraction rate of water-soluble dietary fiber.

Embodiment 2

[0034] Take 2 g of Suaeda salsa filter residue in a 100 mL round-bottomed flask, add 30 mL of pure water and mix evenly, adjust the pH to 10, and place in a 60°C water bath for 30 min, 45 min, 60 min, 75 min, respectively. 90 min. Collect the treated solution, add 5 times the volume of 95% ethanol, ethanol precipitation for 4 h, centrifuge at 5000 r / min for 15 min, and measure the extraction rate of water-soluble dietary fiber.

Embodiment 3

[0036] Take 2 g of Suaeda salsa filter residue in a 100 mL round bottom flask, add 30 mL of pure water and mix evenly, adjust the pH to 10, and place them in water baths at 40°C, 50°C, 60°C, 70°C, and 80°C for reaction 60 min. Collect the treated solution, add 5 times the volume of 95% ethanol, ethanol precipitation for 4 h, centrifuge at 5000 r / min for 15 min, and measure the extraction rate of water-soluble dietary fiber.

Abstract

The invention discloses a suaeda salsa water-soluble dietary fiber extraction process, and a monosaccharide composition and a proportion thereof. The optimized extraction process conditions are as follows: the material-liquid ratio is 1: 15, the pH value is 10, the extraction temperature is 61 DEG C, the extraction time is 75 minutes, and the extraction rate of the obtained suaeda salsa water-soluble dietary fiber is 16.50%; the monosaccharide composition contains mannose, rhamnose, glucuronic acid, galacturonic acid, glucose, galactose, xylose and fucose, and the mass ratio of the mannose to the rhamnose to the glucuronic acid to the galacturonic acid to the glucose to the galactose to the xylose to the fucose is 1.00:9.96:3.08:2.03:1.45:26.32:4.90:10.75. According to the invention, the suaeda salsa is used as a raw material, and a processing method of the water-soluble dietary fiber, which is simple in extraction method and high in extraction efficiency, is determined by an alkali extraction and alcohol precipitation method. And on the other hand, the composition and proportion of the suaeda salsa water-soluble dietary fiber monosaccharide are determined, an exact material basis is provided for further research on mechanisms of reducing blood glucose, reducing lipid and the like, and an innovative basis is developed for determining the material amount of the dietary fiber with homology of medicine and food.

Description

technical field [0001] The invention relates to the field of water-soluble dietary fiber processing, in particular to an extraction process of Suaeda salsa water-soluble dietary fiber and its monosaccharide composition and ratio. Background technique [0002] Dietary fiber is identified as the seventh type of nutrient by the nutritional circles, and is juxtaposed with the traditional six types of nutrients such as protein, fat, carbohydrates, vitamins, minerals, and water. It has the functions of lowering blood cholesterol, lowering blood sugar, preventing cancer and controlling weight. effect. Dietary fiber can be divided into water-soluble dietary fiber and water-insoluble dietary fiber. The characteristics of water-soluble dietary fiber are obviously better than water-insoluble dietary fiber. It contains a large number of side chain groups such as carboxyl and hydroxyl groups, which can affect the pH of the digestive tract in vivo value and osmotic pressure. European an...
