Problems solved by technology

[0007] Aiming at the problems that August melon pulp contains a large amount of colloid, vitamin C and polyphenol oxidase, and because it is generally white in quality, it is easy to brown under the action of polyphenol oxidase and cause the fruit pink gloss to be too poor. Treatment methods such as extraction and color change solve the problems of viscosity and browning of traditional August melon and fruit powder, and provide a new natural and healthy August melon and fruit powder product that can improve the quality of soup color and is convenient for brewing

Embodiment 1

[0044]Select 200Kg of non-rotten blueberry raw materials, wash them, mash the blueberries, beat the pulp, and obtain the blueberry pulp. Take 50L of blueberry pulp, add 200L of 60% ethanol aqueous solution, adjust the pH value to 4 with 0.1mol / L hydrochloric acid, stir and extract at room temperature for 24 hours, filter with 2 layers of gauze, repeat twice, combine the filtrates, and filter residues for later use. Concentrate under reduced pressure below 50°C to 1 / 30 of the original volume, apply HP-20 macroporous resin for adsorption, use 12BV of 45-75% ethanol aqueous solution for gradient elution, collect the eluate, and store the eluate at 50°C Concentrate to dryness under reduced pressure to obtain blueberry pigment.

Embodiment 2

[0046] Choose the ripe August melon to peel, remove the seeds, mash and beat to obtain the August melon pulp, take 100kg of the August melon pulp, add 800g of pectinase and 350g of protease, degas and enzymolyze it in a vacuum at room temperature for 3.5h ( The solution was degassed by vacuuming) to obtain the August melon enzymatic hydrolysis solution, which was stored at a low temperature of 4°C for later use. Mix 100kg of blueberry pomace with 15kg of bean cake powder or peanut cake powder, add 115kg of water, then add 400g of pectinase and 750g of protease to stir evenly, adjust the pH to 5, enzymatically hydrolyze for 4 hours, put it into a fermenter, and heat it at 100 ~110°C sterilization for 25 minutes to obtain the enzymolysis solution; add 6kg of sucrose, 8g of sodium selenite, and 4.5kg of yeast to the enzymolysis solution, stir evenly and carry out aerobic fermentation, the temperature is controlled at 27°C, and the fermentation time is 3 After adjusting the pH to ...

Embodiment 3

[0048] Pick the mature August melon, peel it, remove the seeds, mash it, beat it, and get the August melon fruit pulp, take 200kg of the August melon pulp, add 1.5kg of pectinase and 700g of protease, degas and enzymatically hydrolyze it at room temperature for 4 hours, and get the August melon pulp. Moon melon enzyme hydrolyzate, stored at 5°C for later use. Mix 200kg of blueberry pomace with 15kg of peanut cake powder, add 215kg of water, then add 900g of pectinase and 1200g of protease to stir evenly, adjust the pH to 4.5, enzymatically hydrolyze for 3 hours, put it into a fermentation tank, and heat it at 100-110°C After sterilizing for 30 minutes, the enzymolysis solution was obtained; add 13kg of sucrose, 15g of sodium selenite, and 9kg of yeast to the enzymolysis solution, stir evenly, and carry out aerobic fermentation. The temperature is controlled at 28°C, and the fermentation time is 4 days. Use 1mol / L hydrochloric acid to adjust the pH to 2, and keep it at 70°C fo...

Abstract

The invention relates to a selenium-enriched August melon and fruit powder product and a production process thereof. The selenium-enriched August melon and fruit powder product is obtained through preparation of enzymatic hydrolysis liquid of August melon, fermentation of blueberry pomace, extraction of blueberry pigment, mixing and spray drying . The invention reduces the viscosity of August melon and fruit powder, increases the content of organic selenium and amino acid in the fruit powder, and improves the taste and color of the fruit powder. Through the action of microorganisms, it can effectively remove green and astringent substances, reduce the damage of microorganisms to pigments, and ensure the content of blueberry anthocyanins to the greatest extent. Through the joint action of enzymatic degradation and yeast fermentation, the content of small peptides in the fruit powder is greatly increased, and the characteristics of yeast autolysis are fully utilized to make the fruit powder contain a large amount of antioxidant substances.

Description

technical field [0001] The invention belongs to the field of tea processing, and relates to a selenium-enriched August melon and fruit powder product, and more specifically relates to a production process of August melon and fruit powder. Background technique [0002] Sanye Akebia, commonly known as August Melon, August Zha, and Fried Melon. Deciduous woody vine. Stem bark taupe, with sparse lenticels and small warts. Palmately compound leaves alternate or clustered on short branches; papery or thin papery, ovate to broadly ovate, with wavy teeth or lobes at the margin. The racemes emerge from the clustered leaves of short branches, with purple-brown female flowers in the lower part and lavender male flowers in the upper part. Fruit oblong, straight or slightly curved, grayish white with lavender when mature; numerous seeds, flat ovate, testa reddish brown or dark brown. It has been found through research that the roots, stems, leaves, flowers and fruits of Akebia trifol...
