Problems solved by technology

The existing processing methods of bamboo shoots are generally sun-dried, fire-dried, etc. The processing time is long and the operation is cumbersome, which not only makes it difficult to guarantee the appearance and quality of bamboo shoots, but also greatly reduces the edible value of bamboo shoots
[0005] The prior art also provides a method for processing freeze-dried bamboo shoots. Although this method can effectively retain the heat-sensitive substances contained in the bamboo shoots, the freeze-drying method has a low drying rate, a long time, and high energy consumption in the process. The investment in equipment is huge, and it is difficult to adapt to mass production. In addition, during the freeze-drying process, due to different freezing methods, the shape and size of ice crystals produced will also be different, which will easily affect the subsequent drying rate and quality of freeze-dried items.

Embodiment 1

[0019] The re-drying processing method of spring bamboo shoots of the present embodiment may further comprise the steps:

[0020] a. Preliminarily drying the washed spring bamboo shoots at 120-130° C. for 80-120 minutes, and then drying again at 50-80° C. for 30-60 minutes;

[0021] b. placing the twice-dried spring bamboo shoots obtained in step a for 90-150 min at a temperature of 38-45° C. and a humidity of 18-23%, to obtain the desired spring bamboo shoot product.

[0022] It should be noted that, in this step, the placement time of spring bamboo shoots can realize the object of the present invention between 90-110min, and the placement time of this step can also be more than 150min, but the placement time can prolong the processing time for a long time. It is beneficial to improve production efficiency, so it is not within the protection scope of the present invention. The spring bamboo shoot product that present embodiment makes, the water content of every 500g spring b...

Embodiment 2

[0024] The re-drying processing method of spring bamboo shoots of the present embodiment may further comprise the steps:

[0025] a. Preliminarily dry the washed spring bamboo shoots at 90-110° C. for 80-120 minutes, and then dry them again at 60° C. for 80 minutes;

[0026] b. place the spring bamboo shoots obtained in step a for 130 min under the conditions of 45° C. and 18% humidity through twice drying, to obtain the desired spring bamboo shoots product.

[0027] It should be noted that, in this step, the placement time of spring bamboo shoots can realize the object of the present invention between 90-110min, and the placement time of this step can also be more than 150min, but the placement time can prolong the processing time for a long time. It is beneficial to improve production efficiency, so it is not within the protection scope of the present invention.

Embodiment 3

[0029] The re-drying processing method of spring bamboo shoots of the present embodiment may further comprise the steps:

[0030] a. Preliminarily dry the washed spring bamboo shoots at 70-80°C for 80 minutes, and then dry them again at 80°C for 30 minutes;

[0031] b. place the spring bamboo shoots obtained in step a for 120 minutes at a temperature of 40° C. and a humidity of 18% to obtain the desired spring bamboo shoot product. The spring bamboo shoot product that present embodiment makes, the water content of every 500g spring bamboo shoot is 0.45g.

Abstract

The invention especially provides a redrying processing method for spring bamboo shoots and belongs to the field of food processing. The method comprises steps of: first successively placing the spring bamboo shoots in two different temperature environment for drying, with a high temperature in an initial drying and a low temperature in a secondary drying; and then placing the dried bamboo shoots in environment with certain temperature and humidity for standing. The two dryings employ different temperature and time to avoid destruction of effective components in the spring bamboo shoots and quickly realize moisture in the spring bamboo shoots to required standards. The method for processing spring bamboo shoots can significantly improve the taste of the bamboo shoots and more effectively protect the bamboo shoots, and has characteristics of good product appearance, uniform color, no rot, long shelf life, pure green food, high edible value, simple process and low cost.

Description

technical field [0001] The present invention relates to a kind of processing method of spring bamboo shoots, in particular to a kind of re-drying processing method of spring bamboo shoots Background technique [0002] Bamboo shoots are a good edible product that is rich in nutrition and has a certain health care effect. It has a good color, fragrance, taste, freshness and taste, and is very popular. Known as the "Mountain Treasures of Poor Scholars", there is a saying that "no bamboo shoots make a banquet". The nutrients of bamboo shoots mainly include protein, amino acid, fat, sugar, inorganic salt and so on. The human body must constantly absorb protein from food in order to maintain health. Bamboo shoots are rich in protein, containing 1.49-4.04g per 100g of fresh bamboo shoots, with an average of about 2.05g. It is one of the vegetables with the highest protein content. Protein in food needs to be decomposed into amino acids to be absorbed by the human body. Some of th...
