Embodiment 1

[0040] like figure 1 As shown, a process for extracting soluble dietary fiber from August melon peel with hypoglycemic function includes the following steps:

[0041] Step 1. Crushing and extraction: The peel of August melon is the peel of fresh and mature August melon. After washing and drying the water naturally, it is dried at 50 ° C for 24 hours, crushed and passed through a 60-mesh sieve to obtain August melon. Peel powder; extract by mixing August melon pericarp powder with phosphate buffer, wherein the material-liquid ratio of August melon pericarp powder and phosphate buffer is 1:20 (g / mL).

[0042] Step 2, papain enzymolysis: adjust the pH of the August melon pericarp buffer solution extract to 7, add 600U / g papain, put it into a water bath with a temperature of 70 ° C and heat for 30 minutes, and heat the water bath to 100 °C. The enzyme was inactivated at 100°C for 10 min, and then cooled naturally at room temperature.

[0043] Step 3, α-amylase enzymatic hydrolys...

[0048] Experimental example 1: Effect of solid-liquid ratio on the extraction of soluble dietary fiber from August melon peel

[0049] 1. Experimental method

[0050] Take 2 g of August melon peel, the ratio of material to liquid is 1:10, 1:15, 1:20, 1:25, 1:30 (g / mL) and other conditions are fixed and unchanged with Example 1, respectively explore In the change of the yield of soluble dietary fiber in August melon peel with different solid-liquid ratios, each group was repeated three times.

[0051] 2. Experimental results

[0052] The result is as figure 2 It is known that the ratio of solid to liquid has a significant effect on the extraction rate of SDF from August melon peel (P<0.05). g / mL), the extraction amount of soluble dietary fiber from August melon peel was significantly higher than that when the solid-liquid ratio was 1:10, 1:15, 1:25, 1:30 (g / mL) . Therefore, in this extraction condition, 1:20 (g / mL) was the best solid-liquid ratio for the extraction of sol...

[0053] Experimental example 2: The effect of enzymatic hydrolysis temperature of cellulase on the extraction of soluble dietary fiber from August melon peel

[0054] 1. Experimental method

[0055] Take 2 g of August melon peel, the enzymatic hydrolysis temperatures were 40, 45, 50, 55, and 60 °C, and other conditions were the same as those in Example 1. The change of fiber yield was repeated three times for each group.

[0056] 2. Experimental results

[0057] The result is as image 3 It is known that the enzymatic hydrolysis temperature has a significant effect on the extraction rate of SDF from August melon peel (P<0.05). The amount of soluble dietary fiber extracted from moon melon peel was significantly higher than that of soluble dietary fiber when the enzymatic hydrolysis temperature was 40, 45, 55, and 60 ℃. Therefore, in this extraction condition, 50℃ was the optimal enzymatic hydrolysis temperature for the extraction of soluble dietary fiber from August melon pe...

Abstract

The invention relates to the technical field of soluble dietary fiber processing and preparation, and discloses an extraction process and application of stauntonia latifolia pericarp soluble dietary fiber with a hypoglycemic function, and the stauntonia latifolia pericarp soluble dietary fiber with the hypoglycemic function is obtained by taking stauntonia latifolia pericarp as a raw material, sequentially carrying out enzymolysis treatment through papain, alpha-amylase and cellulase, concentrating, carrying out alcohol precipitation and drying. The process method is simple to operate, convenient to use, reasonable, stable and quantifiable, and has important application value. In-vitro hypoglycemic activity evaluation shows that the soluble dietary fiber obtained by the method can significantly reduce the activity of alpha-glucosidase and effectively control the increase of postprandial blood sugar, and the inhibition effect may cause the blocking of the absorption of glucose by intestinal tracts, thereby generating a relatively ideal hypoglycemic effect. Certain effects of reducing blood sugar and blood fat, preventing colon cancer, cardiovascular diseases and the like are achieved. Therefore, the stauntonia latifolia peel soluble dietary fiber has a good application prospect in the aspect of developing related hypoglycemic functional foods or medicines.

Description

technical field [0001] The invention relates to the technical field of processing and preparation of soluble dietary fiber, in particular to an extraction process and application of soluble dietary fiber from August melon peel with hypoglycemic function. Background technique [0002] Akebia trifoliate kiodz (Akebia trifoliate kiodz) is a vine plant in the Akebia family. August melons are distributed in southern my country, the Yangtze River Basin and Northwest China, as well as in Southeast Asia, Japan and other places abroad. The fruit of August melon is edible, rich in sugar, various vitamins and various amino acids required by the human body, as well as polyphenols, flavonoids, etc.; especially, the content of free essential amino acids is very high. August melon also has health care medicinal effects such as anti-aging, beauty and beauty, immunity enhancement, anti-tumor, lowering blood pressure, and diuresis. It is a typical medicinal and edible plant. August melon ge...
