Embodiment Construction

[0032] Peeling: After peeling the onion, wash and soak for 15-30 minutes.

[0033] Slicing: cut into a pseudo-cubic shape greater than or equal to 6*6mm and less than or equal to 15*15mm.

[0034] Drying: Control the temperature at 60-65 and dry for 1.5-2.5 hours, then reinstall the furnace, control the temperature at 20-25 and dry for 1.5-2.5 hours; until the onion moisture is 6%- At 7%, take it out.

[0035] Sorting: Sorting out onion slices and magazines with irregular shape and inconsistent color.

[0036] Screening: Sieve through sieves of different sizes.

[0037] Inspection: After the heavy metals are taken out by a magnetic field, they are detected by a metal detector; and then irradiated with ultraviolet light to control the microbial indicators within the allowable range.

[0038] Packing: Use glass or double-layer plastic bags or aluminum foil bags for airtight packaging.

Abstract

The invention relates to an onion product, and particularly relates to a dehydrated white onion processing method which comprises the follows processes: peeling, slicing, drying, sorting, screening, testing, packaging and warehousing. The beneficial effects of the dehydrated white onion processing method are that: dehydrated white onions produced by the processing method are pure in taste, can be restored only by soaking with warm water, are fresh in four seasons, and retain the original nutrients and flavor of onion, and the processing method solves the problems of damping, low sorting efficiency, short shelf life, difficulty in storage and the like of the dehydrated onions in dehydrated onion processing in the prior art.

Description

technical field [0001] The invention belongs to an onion product, in particular to a method for processing dehydrated white onion grains. Background technique [0002] 1. Onion is a characteristic vegetable integrating nutrition, medical treatment and health care. It is known as the "Queen of Vegetables" in Europe and America. According to measurements, every 100 grams of fresh onion contains about 88 grams of water, 1 to 1.8 grams of protein, 0.3 to 0.5 grams of fat, 5 to 8 grams of carbohydrates, 0.5 grams of crude fiber, 130 kilojoules of calories, 12 milligrams of calcium, and 12 milligrams of phosphorus. 46 mg, iron 0.6 mg, vitamin C 14 mg, niacin 0.5 mg, riboflavin 0.05 mg, thiamine 0.08 mg, carotene 1.2 mg. It also contains caffeic acid, sinapic acid, cinnamic acid, citrate, polysaccharides and various amino acids. Onions also have the health benefits of dispelling wind-cold, lowering blood sugar, lowering blood fat, treating diabetes and preventing osteoporosis, bu...
