Embodiment 1

[0024] Take fresh Ruo bamboo leaves that have fully grown up but have not yet formed an obvious wax layer, and soak the Ruo bamboo leaves in hydrogen Sodium oxide aqueous solution to dewax and soften, and make the dirt on the blade surface fall off for easy cleaning. So soaked for 30 days. Take out the bamboo leaves and rinse the surface dirt with clean water. The used sodium hydroxide aqueous solution continues to be used for the treatment of the next batch of raw materials after concentration adjustment. Drain the cleaned Ruo bamboo leaves and pickle them layer by layer with salt: put the Ruo bamboo leaves in layers in the cement pool, each layer is less than 1 cm thick, place one layer, press it tightly, Sprinkle a layer of salt between the two layers of bamboo leaves (the amount of salt for each layer is the total amount of salt divided by the number of layers of bamboo leaves). So until it is packed near the mouth of the pond, the top layer is the salt layer, and the t...

Embodiment 2

[0026] Take fresh Ruo bamboo leaves that have fully grown but have not yet formed an obvious wax layer. According to the weight ratio of the added Ruo bamboo leaves to the 4% mass concentration of sodium hydroxide aqueous solution is 6:4, the Ruo bamboo leaves are soaked in the sodium hydroxide aqueous solution to play the role of dewaxing and softening, and make the leaves Dirt on the surface comes off for easy cleaning. Do this for 40 days. Take out the bamboo leaves and rinse the surface dirt with clean water. The used sodium hydroxide aqueous solution continues to be used for the treatment of the next batch of raw materials after concentration adjustment. Drain the cleaned Ruo bamboo leaves and pickle them layer by layer with salt: put the Ruo bamboo leaves in layers in the cement pool, each layer is less than 1 cm thick, place one layer, press it tightly, Sprinkle a layer of salt between the two layers of bamboo leaves (the amount of salt for each layer is the total am...

Embodiment 3

[0028] Take fresh Ruo bamboo leaves that have fully grown but have not yet formed an obvious wax layer. According to the weight ratio of the added Ruo bamboo leaf and the sodium hydroxide aqueous solution of 5% mass concentration is the ratio of 7:3, the Ruo bamboo leaf is soaked in the sodium hydroxide aqueous solution, plays the effect of dewaxing and softening Ruo bamboo leaf, And make the dirt on the surface of the blade fall off for easy cleaning. Do this for 60 days. Take out the bamboo leaves and rinse the surface dirt with clean water. The used sodium hydroxide aqueous solution continues to be used for the treatment of the next batch of raw materials after concentration adjustment. Drain the cleaned Ruo bamboo leaves, and press the Ruo bamboo leaves into 56% saline solution for 360 days according to the weight ratio of Ruo bamboo leaves and salt water: 1:1. The used saline solution, after concentration adjustment, continues to be used for the preservation of the nex...

Abstract

The invention relates to a non-hot processing method for zongzi leaves, which comprises the following steps of: soaking indocalamus leaves which sufficiently grow up, but are not provided with obvious wax layers in aqueous solution of sodium hydroxide so as to dewax, soften and clean the indocalamus leaves; taking out the indocalamus leaves, cleaning the indocalamus leaves, draining the indocalamus leaves and then pickling the indocalamus leaves in salt or aqueous solution of salt; and finally, taking out the indocalamus leaves, rinsing the indocalamus leaves in the aqueous solution of salt clean, then classifying the indocalamus leaves according to the standard of the zongzi leaves, respectively placing the indocalamus leaves into plastic bags for food packaging and carrying out vacuum sealing on the plastic bags. The method not only has no energy consumption caused by heating, but also has no water consumption caused by using the previous rehydration process, also has no food safetyhazard and is a processing method which is energy-saving, can be used for reducing the consumption and is convenient and safe.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a method for processing zong leaves without heating and energy consumption. Background technique [0002] Zongye is a kind of material for Zongzi packaging processed from bamboo leaves. There are two traditional processing methods of zong leaves: [0003] The first method is the direct drying method. The method is to dry or sun-dry the fresh Ruo bamboo leaves after heat treatment. This method has two disadvantages. One is that heat treatment is required when fixing and drying, and heat treatment needs to consume a lot of energy; It consumes water again. These not only increase the production cost, but also cause the inconvenience of using the zong leaves. [0004] The second method is sterilization preservation method. The method is to first marinate the bamboo leaves to make semi-finished products, then heat and boil the semi-finished products in batches to soften them to ma...
