Embodiment 1

[0010] A method for extracting anthocyanins from taro bark, comprising the following steps: take 70 parts by weight of taro bark, clean and dehydrate it, put it into a fermentation tank, add 8 parts by weight of Artemisia annua powder, and then add 10 parts by weight of Medical hydrochloric acid, after reacting for 20 hours, add 1 weight part of licorice powder, 15 weight parts of chlorophyll, 8 weight parts of sodium sulfate dodecahydrate, stir well and carry out distillation, the distillation temperature is 100~120 ℃, and the time is 5 to 10 hours, then cooled to 15 to 40 °C and then added edible alcohol for pointing, after 20 to 30 hours, the upper layer of wastewater was drawn out, and the bottom juice was anthocyanin.

Embodiment 2

[0012] A method for extracting anthocyanins from taro bark, comprising the following steps: taking 80 parts by weight of taro bark, cleaning and dehydrating, putting it into a fermentation tank, adding 12 parts by weight of Artemisia annua powder, and then adding 15 parts by weight of Medical hydrochloric acid, after reacting for 30 hours, add 3 parts by weight of licorice powder, 10 parts by weight of chlorophyll, and 6 parts by weight of sodium sulfate dodecahydrate, stir evenly and carry out distillation. The distillation temperature is 100-120 °C and the time is 5 to 10 hours, then cooled to 15 to 40 °C and then added edible alcohol for pointing, after 20 to 30 hours, the upper layer of wastewater was drawn out, and the bottom juice was anthocyanin.

Embodiment 3

[0014] A method for extracting anthocyanins from taro bark, comprising the following steps: taking 75 parts by weight of taro bark, cleaning and dehydrating, putting it into a fermentation tank, adding 10 parts by weight of Artemisia annua powder, and then adding 13 parts by weight of Medical hydrochloric acid, after reacting for 25 hours, add 2 parts by weight of licorice powder, 13 parts by weight of chlorophyll, and 7 parts by weight of sodium sulfate dodecahydrate, stir evenly and carry out distillation. The distillation temperature is 100-120 ° C, and the time is 5 to 10 hours, then cooled to 15 to 40 °C and then added edible alcohol for pointing, after 20 to 30 hours, the upper layer of wastewater was drawn out, and the bottom juice was anthocyanin.

Abstract

The invention discloses a method for extracting anthocyanidin from Canna edulis ker peel. The method comprises the following steps: weighing 70 to 80 parts by weight of Canna edulis ker peel, cleaningthe Canna edulis ker peel, then dehydrating the Canna edulis ker peel, and filling a fermentation tank with the dehydrated Canna edulis ker peel; adding 8 to 12 parts by weight of sweet wormwood powder and then adding 10 to 15 parts by weight of medical hydrochloric acid; carrying out a reaction for 20 to 30 h, then adding 1 to 3 parts by weight of licorice root powder, 10 to 15 parts by weight of a leaf-greening agent and 6 to 8 parts by weight of sodium sulfate dodecahydrate, carrying out uniform mixing under stirring, and then performing distillation; carrying out cooling to 15 to 40 DEG Cand adding edible alcohol for point coagulation; and extracting waste water at an upper layer after 20 to 30 h, wherein bottom precipitate juice is anthocyanidin. The method of the invention can expand the application range of the Canna edulis ker peel and increase the added value of the Canna edulis ker peel, and has good economic prospects.

Description

technical field [0001] The invention relates to a method for extracting anthocyanins from plantain taro skin, and belongs to the technical field of anthocyanins preparation. Background technique [0002] Canna taro, also known as dry lotus root, banana root, and ginger taro, is a plant of the genus Canna in the banana family. Good raw material for processing. Canna taro starch has a large particle size, low gelatinization temperature, good paste transparency, high chain starch content, good film-forming properties, and a large molecular weight, which is close to potato starch, and has good application properties. The development and utilization of plantain taro is mainly to produce starch, and to develop starch deep-processing products and food items such as vermicelli and vermicelli. But at the same time, in the development process of plantain taro, the meat quality of plantain taro is mainly used, and its outer skin is seldom utilized. Contents of the invention [000...
