Steamed rice dumpling leaf rich in sodium copper chlorophyllin and making method of steamed rice dumpling leaf

Abstract

The invention discloses a steamed rice dumpling leaf rich in sodium copper chlorophyllin and a making method of the steamed rice dumpling leaf. On the basis of a conventional copper substitution technique of copper sulfate, sodium hydroxide saponification treatment is implemented to convert chlorophyll into sodium copper chlorophyllin, and the mass percentage ratio of sodium hydroxide to the steamed rice dumpling leaf is (0.1-0.5):100. The making method of the steamed rice dumpling leaf comprises the following steps: putting the steamed rice dumpling leaf into clean water to wash and soak for 1 hour; putting the soaked steamed rice dumpling leaf into boiled water with 10% of copper sulfate to further blanch for 5-10 minutes; cutting off the petiole of the blanched steamed rice dumpling leaf, and adding a 5% sodium hydroxide solution for saponification for 2 hours; further washing for 5 minutes with clean water; draining off the water, and drying at low temperature of 30-50 DEG C until the water content is less than 10%; and packaging according to the number or the weight of leaves. By adopting the steamed rice dumpling leaf, free copper in steamed rice dumpling leaves can be removed, people can be prevented from emesis, diarrhea or heavy metal poisoning caused by excessive copper ions, and a nutrition healthcare function is achieved as the steamed rice dumpling leaf is rich in sodium copper chlorophyllin.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to zong leaves rich in sodium copper chlorophyllin and a preparation method thereof. Background technique [0002] In the vast areas of southern my country, zongzi leaves have been used for a long time to make zongzi, package other foods, serve as decorations on the table and foil of food, and can also be used for making utensils. Zong leaves contain a large amount of nutrients such as chlorophyll and a variety of amino acids that are beneficial to the human body, and have a special bamboo fragrance and antiseptic effect. "Compendium of Materia Medica" records that Zongye has the effects of clearing away heat and stopping bleeding, detoxifying and reducing swelling, and treating hematemesis, bleeding, dysuria, and carbuncle. Studies in recent years have proved that the polysaccharides from Zongye leaves have anti-cancer effects. "Dictionary of Chinese Medicine" also int...

Problems solved by technology

However, excessive intake of residual free copper in zong leaves can easily lead to vomiting, diarrhea, and even heavy metal poisoning.

[0004] The existing Zongye processing method uses copper ions to replace the magnesium ions of chlorophyll to form copper chlorophyll with stable properties and green color, while achieving the protective effect on chlorophyll, copper chlorophyll cannot be dissociated in Zongye leaves and cannot be absorbed by the human body. Utilize, waste extremely precious natural resources
