A method for processing zongzi leaves by using hemp bamboo leaves

Abstract

The invention discloses a method for utilizing dendrocalamus affinis leaves to process zongzi wrapping leaves. Dendrocalamus affinis leaves are adopted as a processing material for zongzi wrapping leaves. The method comprises the technological processes of dendrocalamus affinis leaf picking, green color protecting through a green-preserving agent, sorting and stacking, ultralow temperature freezing treatment, drying, and discharging and dampening, wherein the green color protecting technology comprises the steps of placing the leaves in sodium copper chlorophyllin to be soaked for 20 min, and then, placing the soaked leaves into an electrochemical device to be subjected to electrochemical treatment. According to the method, the dendrocalamus affinis leaves can be utilized to supplement the zongzi wrapping leaf resource, and the contradiction between supply and demand is relieved; the green color of the zongzi wrapping leaves is achieved through utilizing the sodium copper chlorophyllin, and the food safety problem is avoided; and the reaction is promoted through adopting an electrochemical manner.

Description

technical field [0001] The invention relates to the technical field of forest product processing, in particular to a method for processing zong leaves by using hemp bamboo leaves. Background technique [0002] Zongye is one of the essential materials for making "Zongzi". There are many varieties of zong leaves, which are generally processed from reed leaves, reed leaves, chopsticks leaves, lotus leaves, bamboo shells, etc. Among them, the reed bamboo leaves that grow in the middle and lower reaches of the Yangtze River are characterized by their large leaves, thin texture, and flexibility. The characteristics of good taste and mellow smell are the most popular, and it has become the bulk of Zongye, so it is widely used in food processing enterprises. [0003] However, with the growth of people’s consumption of zongzi, the supply of zongzi leaves has long been in short supply. Relevant surveys show that the production capacity of the domestic zongzi industry has increased by...

Problems solved by technology

[0003] However, with the growth of people’s consumption of zongzi, the supply of zongzi leaves has long been in short supply. Relevant surveys show that the production capacity of the domestic zongzi industry has increased by about 25% in recent years, and there are still a large number of zongzi leaves to be sold to Japan, South Korea, Southeast Asia and Taiwan. and other regions, but as the packaging product of Zongzi—Zongye, its processing and production capacity has only increased by about 10%. Therefore, it is difficult to meet market demand by relying solely on bamboo leaves, and it is urgent to supplement Zongye resources and find substitutes question

[0004] On the other hand, in order to ensure the bright green color of zong leaves during the processing of existing zong leaves, it is necessary to soak the fresh leaves with color-protecting agents such as industrial copper sulfate or copper chloride to preserve the color, which will endanger human health after eating

[0005] In addition, when zongzi is practical, it is often difficult to separate the glutinous rice from the zong leaves, and even the zongzi cannot be united and scattered on the whole zongzi leaves, resulting in inconvenient eating and losing the taste of zongzi
