Spicy and hot lotus root slice

Abstract

The present invention discloses a spicy and hot lotus root slice and the preparation steps are as follows: firstly, selecting materials; secondly, protecting color and preserving: the color protecting liquid is a liquid fully stirred and dissolved by adding 2-3% citric acid in saturated saline solution; thirdly, slicing; fourthly, salt pickling: the lotus roots are immersed in a salt pickling solution and the salt pickling solution is a saturated saline solution adjusted with citric acid to a pH of 2 to 5; fifthly, precooking: putting the salt pickled lotus root slices into a mixed solution of 0.5-1.5% of citric acid and 1.5-2.5% of saline solution, boiling and keeping for 10-15min, and taking the boiled lotus root slices out and cooling with purified clear water; sixthly, blending soup and seasoning; and seventhly, packaging. The lotus root slices obtained by color protecting, salt pickling and pre-cooking do not produce browning and maintain a white color of the lotus root itself, will not affect the lotus roots, are eating healthy, have a fragrant and crisp taste, an appropriate hot and spicy flavor, can be eaten the bag is opened, provide a method for the deep processing of the lotus roots, and effectively protect the enthusiasm of the local lotus root peasants for lotus root planting.

Description

technical field [0001] The invention relates to a lotus root processing technology, in particular to a spicy lotus root slice. Background technique [0002] Lotus root is widely distributed in our country and is rich in resources. It can be found from the land of Northeast China to Hainan Island, from the coast of the East China Sea to the Tibetan plateau. Due to different natural resource conditions, each main production area has formed a lotus root industry with different characteristics and in line with local development conditions. Suzhou belongs to the warm temperate semi-humid monsoon climate. The main varieties suitable for planting are American Snow Lotus No. 3, Beijing Luohua, Yugoslav Snow Lotus Series, Space Lotus No. 3, E Lian No. 4, E Lian No. 5, E Lian No. 6, etc. Due to the local climate conditions There are several problems in the planted lotus root after harvesting: one is that the lotus root after harvesting is very easy to go bad, and it is too troublesom...

Problems solved by technology

Suzhou belongs to the warm temperate semi-humid monsoon climate. The main varieties suitable for planting are American Snow Lotus No. 3, Beijing Luohua, Yugoslav Snow Lotus Series, Space Lotus No. 3, E Lian No. 4, E Lian No. 5, E Lian No. 6, etc. Due to the local climate conditions There are several problems in the planted lotus root after harvesting: one is that the lotus root after harvesting is very easy to go bad, and it is too troublesome to use film tent method and soil burial method, and it can only be preserved within 7 days; It is concentrated harvesting, and the selling price of fresh lotus root is cheap, which hurts farmers, so the deep processing of lotus root is particularly urgent

[0003] However, the biggest problem of lotus root processing is discoloration. Sodium sulfite is used as a color-protecting agent in existing technologies, but its use has been banned due to SO2 residues. How to eat healthily while maintaining its color and flavor is the key to the processing technology of lotus root
