Problems solved by technology

For a long time, there has been no water-soluble orange peel fiber products at home and abroad because of the strong bitterness and deep color of citrus peels, and the cellulose and hemicellulose in citrus peels are insoluble in water.

example 1

[0016] Example 1, food raw material type water-soluble orange peel fiber

[0017] Color protection: 100kg of fresh citrus peels for the production of canned orange slices are selected and removed, soaked in 0.15% vitamin C solution for 8 minutes, and the temperature of acid water is 42°C. After soaking, remove the citrus peels and drain moisture.

[0018] Drying: 100kg of fresh citrus peels after color protection are dried with belt-type microwave drying equipment: microwave power is 20%-30%, and the drying time is 120min. Ventilation and moisture removal. The moisture content of citrus peel at the end of drying is 20%-22%.

[0019] The orange peel after drying is required to keep the color of fresh orange peel without obvious black peel.

[0020] In order to prevent the volatilization of aromatic oil and the oxidation of orange peel pigment during the storage of dried peels, the dried orange peels should be sealed and stored away from light.

[0021] Pulverization: In ord...

[0034] Example 2, water-soluble orange peel fiber beverage

[0035] Color protection: 100kg of fresh citrus peels for the production of canned orange slices, after selection and removal of impurities, soak in 0.15% citric acid solution for 10 minutes, the acid water temperature is 55°C, remove the citrus peels after soaking, and drain the water .

[0036] Drying, pulverizing operation are with example 1.

[0037] Extraction: The crushed orange peel is placed in CO 2 In the supercritical extraction tank, the extraction process conditions are: extraction temperature 40°C, extraction pressure 25Mpa, extraction time 180min, separation I temperature 30°C, separation I pressure 6-8Mpa, separation II temperature 20°C, separation II pressure 4-5Mpa, CO 2 The flow rate is 45-50l / h.kg raw material.

[0038] Separation, rehydration, ultrafine pulverization, and enzymatic hydrolysis are the same as in Example 1.

[0039] Concentration: The material after deactivating the enzyme is co...

Abstract

The invention relates to a method for producing water-soluble citrus peel fibres. Fresh citrus peels are taken as raw materials and are subjected to the technology such as colour preserving, drying and crushing, CO2 supercritical bitter and color removal, superfine pulverizing and enzymolysis, concentration, high-pressure homogenization, filling and sterilizing to convert cellulose, hemicellulose, pectin and the like in the citrus peels into the water-soluble citrus peel fibres which can be eaten directly and also can be taken as raw materials of high-carbohydrate fibre functional foods. Aromatic oil and pigments of the citrus are obtained in the production process. Therefore, the full use of the citrus and zero emission of peel residue are realized in the citrus processing process.

Description

technical field [0001] The invention relates to a production method of water-soluble orange peel fiber. Background technique [0002] Citrus is one of the fruits with the largest output in the world, and it is also an export agricultural product with traditional advantages in my country. In 2008, the planting area of ​​citrus in my country reached 1.91 million hectares, and the output reached 20.59 million tons. Both the planting area and output of citrus in China ranked first in the world. Citrus peels account for about 30% of the total amount of citrus, and there are about 6 million tons of citrus peels in the country every year. At present, 99% of citrus peels are used in formulas of Chinese patent medicines except for a very small amount of citrus peels. It is discarded as waste, which not only causes waste of resources, but also causes environmental pollution. If this huge resource is comprehensively utilized and waste is turned into wealth, the comprehensive economic...
