specific Embodiment approach 2

[0030] Embodiment 2 of the present invention provides another kind of anthocyanin beverage, and its difference with the anthocyanin beverage described in Embodiment 1 is that: the food additive mainly consists of peppermint, citric acid, chitosan, EDTA, stevia Glycoside, D-sodium erythorbate and sorbic acid, the extract of Red Elephant Grass and various food additives are mixed and prepared according to the following ratios by weight: 100 parts of the extract of Red Elephant Grass, 1-2 parts of Peppermint , 0.005-0.015 parts of citric acid, 0.02-0.04 parts of chitosan, 0.04-0.06 parts of EDTA; 0.06-0.08 parts of stevioside, 0.005-0.015 parts of D-isoascorbate, and 0.005-0.015 parts of sorbic acid.

[0031] The licorice, peppermint, citric acid, chitosan, stevioside, and sorbic acid are food-grade, mainly used to adjust the mouthfeel; EDTA and D-sodium erythorbate are analytically pure, and mainly play a color-fixing role; EDTA is ethylenediamine tetraacetic acid. All the abov...

specific Embodiment approach 3

[0040] The third embodiment of the present invention provides the application of red elephant grass in the preparation of anthocyanin beverage, which is characterized in that: the extract of red elephant grass is used as the main component of the beverage in the preparation process of the beverage.

[0041] The preparation technology of described beverage specifically comprises the following steps:

[0042] ① Beating: choose freshly washed stems and / or leaves of red elephant grass as raw materials. Before beating, it is best to cut the stems and / or leaves of freshly washed red elephant grass to facilitate beating. Then add water and beat according to the weight ratio of red elephant grass: pure water = 1:2-4 to obtain a slurry mixture. When beating, use a beater to beat the stems and / or leaves of red elephant grass into fibrous strands, usually using a beater at 3500 rpm for 8-10 minutes to complete the beating process.

[0043] ②Leaching: firstly extract the slurry mixt...

Embodiment 1

[0051] Follow the steps below to prepare an anthocyanin drink:

[0052] ① Beating: Cut the freshly washed stems and / or leaves of Red Elephant Grass into 2-3cm stem segments. After that, add water and beat according to the weight ratio of red elephant grass: pure water = 1:3, and use a beater at 3500 rpm for 9 minutes to obtain a slurry mixture.

[0053] ②Leaching: First, mix the slurry mixture obtained in step ① with 85% ethanol aqueous solution at 60°C according to the volume ratio of 4 parts of slurry mixture: 1 part of ethanol aqueous solution, reflux for 1 hour, and then filter Collect the primary extract, then extract the filtered filter residue with 5 times the weight of pure water at 60°C for 1.5 hours, filter and discard the filter residue to obtain the secondary extract;

[0054] 3. Filtration: After combining the primary extract and the secondary extract obtained in step 2, filter with an 8000Da membrane, discard the filter residue to obtain the extract of Red Eleph...

Abstract

The invention relates to an anthocyanin drink and the application of red elephant grass in preparing the anthocyanin drink. The feature of the anthocyanin drink is that the extract of red elephant grass is used as the main component in the drink. The invention utilizes the characteristics of red elephant grass, such as easy planting, high yield, high quality, and containing anthocyanin, to find a raw material that is easy to industrialize for the development of anthocyanin beverage products, and the produced anthocyanin beverage not only has low cost , and rich in nutrients, no pesticide residues.

Description

technical field [0001] The invention relates to an anthocyanin beverage and the application of red elephant grass in the preparation of anthocyanin beverage, which belongs to the field of agricultural by-product processing. Background technique [0002] Anthocyanidin, also known as anthocyanidin, is a kind of water-soluble natural pigment widely present in plants in nature, belonging to flavonoid compounds. Anthocyanins are also the main coloring substances in plant petals, and most of the colorful colors of fruits, vegetables, and flowers are related to them. Anthocyanin is a pure natural anti-aging nutritional supplement. Studies have proved that it is the most effective antioxidant found by humans today. Its antioxidant performance is fifty times higher than vitamin E and twenty times higher than vitamin C. It can be detected in blood within 20 minutes after taking it. Anthocyanins are known as "oral skin cosmetics" in Europe, especially blueberry anthocyanins, which ha...
