Embodiment Construction

[0022] A comprehensive utilization method of onion waste skin slag includes the following steps:

[0023] (1) The onion skin residue is manually sorted, and the impurities are removed and then rinsed with water with a pressure equal to or lower than 250BAR; then sent to the ternary dehydrated vegetable shaker produced by Xinxiang Nuoshi Vibration Machinery Factory Shake dehydration to obtain dehydrated onion skin residue.

[0024] (2) Frozen the dehydrated onion skin slag in the quick-freezer produced by Beijing Brose Refrigeration Equipment Co., Ltd. to -28~-35℃. After freezing for 2~3 hours, enter the JDG type produced by Lanzhou Kejin Vacuum Freeze-drying Technology Co., Ltd. The vacuum freeze-drying machine is freeze-dried under the conditions of the heating plate temperature of the vacuum freeze-drying machine at 70~110℃ and the vacuum degree at 110~130Pa. The surface temperature of the dried material does not exceed 60℃ during the freeze drying. When the moisture content of ...

Abstract

The invention relates to a comprehensive utilization method of wasted onion peels. The method comprises the following steps: firstly, sorting and rinsing onion peels and then performing dewatering through vibration to obtain dewatered onion peels; secondly, feeding the dewatered onion peels into a vacuum freeze dryer so as to freeze dry the onion peels until the water content of the freeze-dried object is less than 7 percent to obtain the freeze-dried onion peels; thirdly, crushing the freeze-dried onion peels to obtain the onion peel powder; and finally packaging the onion peel powder to obtain the onion peel powder product. The comprehensive utilization method produces the onion peel powder by combining vacuum freeze drying technology and jet milling technology and therefore ensures that the thermally sensitive nutritive material is not decomposed or lost, maintains the nutritive materials in the onion skin and peel, reduces the production cost and ensures the product quality.

Description

Technical field [0001] The invention relates to the field of onion deep processing, in particular to a comprehensive utilization method of onion waste skin residue. Background technique [0002] Onions, also known as ball onions, round onions, jade onions, and shallots, are two-year-old herbs of the genus Allium in the Liliaceae family. They have been used as vegetables for 5,000 years. Onions are widely distributed in my country, and the planting areas are mainly distributed in Gansu, Inner Mongolia, Xinjiang, Shandong and other places. Although onions have a spicy smell, they are rich in nutrients. Onion bulbs and leaves contain a greasy volatile substance called propylene sulfide, which has a pungent taste. This substance can resist cold, resist influenza viruses, and has a strong bactericidal effect; The extract can inhibit the growth of various microorganisms such as Staphylococcus, Streptococcus, Vibrio, Bacillus. Modern medicine has proven that onions have anti-inflammat...
