Problems solved by technology

However, day lily has poor storage performance after picking, and it is very easy to rot and deteriorate, causing great economic losses; at the same time, it is also very easy to oxidize and fade, resulting in unsightly products; therefore, it needs deep processing as soon as possible after picking
At present, part of day lily is used for stewing, hot pot, etc., or as an ingredient for other products, and some is used for drying and salting, but these forms are semi-finished products. When people eat, they need to add various seasonings. The spices stored in general households are limited, so it is inconvenient to eat, and it is not suitable for contemporary fast-paced urban life

Abstract

The invention relates to a production method of instant day lilies. The production method comprises steps as follows: raw material selection; soaking; cleaning; fixation; cooling: placing fixed day lilies in an ice-water bath containing edible acetic acid for quick cooling; cold air dehydration: placing cooled day lilies in a shaking type airing bed and cold-airing the day lilies with air of an air cooler for 30-50 min to remove part of moisture; material mixing; sterilization, packing and the like. The day lilies are soaked with proper amounts of edible salt and citric acid for color protection, then high-temperature steam (103-108 DEG C) is used for fixation and enzyme deactivation, and browning of the day lilies and product pollution are avoided; the temperature of the day lilies is quickly decreased to 4-8 DEG C with an acetic acid aqueous solution ice-bath technology, the original color and nutria ingredients are kept, and the instant day lilies are easy to store and convenient to carry, have advantages that the day lilies are convenient to eat, safe, tasty, efficient to absorb, suitable for people of all ages and the like and have higher promotional value.

Description

technical field [0001] The invention relates to a food processing method, in particular to a preparation method of instant day lily. Background technique [0002] Day lily, also known as "day lily", has the effects of calming the nerves and refreshing the brain, increasing intelligence and broadening the chest, beautifying and nourishing blood, antipyretic and disinfecting, eliminating troubles and clearing milk, and reducing inflammation and dampness. According to the "Dictionary of Traditional Chinese Medicine", day lily contains 0.7% alkaloids, 1.8% glycosides, 0.75% flavonoids, 0.36% β-carotene and other rich pollen, sugar, protein, vitamin C, calcium, fat, amino acids and other human body. Therefore, day lily is not only a kind of delicious food, but also a better health food, and has a wide market at home and abroad. However, day lily has poor storage performance after picking, and it is very easy to rot and deteriorate, causing great economic losses; at the same time...
