Embodiment 1

[0020] Example 1: Purple potato-mushroom compound nutrition instant powder prepared from purple potato residue and mushroom after pigment extraction

[0021] After the pigment is extracted, the purple potato dregs are rinsed twice with clean water, then soaked in hot water at 75°C for 15 minutes at a material-to-liquid ratio of 1:5 (5 times the weight of the purple sweet potato dregs), and then removed and drained. Fresh shiitake mushrooms are cleaned to remove surface impurities, cut into slices with a thickness of 5 mm, blanched in boiling water for 4 minutes, taken out, and washed with 0.1% citric acid, 0.02% ascorbic acid and 0.015% edetate disodium (EDTA-2Na) is configured as a composite color protectant solution and soaked for 8 minutes, then remove and drain. The processed purple potato residue and shiitake mushroom slices were placed in a drying oven, the initial temperature was set at 40 °C, and then the temperature was increased by 10 °C every 1 h until the moisture...

Embodiment 2

[0022] Embodiment 2: Purple potato residue and matsutake fungus are used as raw materials to prepare purple potato-matsutake compound nutrition instant powder

[0023]After the pigment is extracted, the purple potato dregs are rinsed twice with clean water, then soaked in hot water at 80°C for 10 minutes at a solid-to-liquid ratio of 1:3 (3 times the weight of the purple sweet potato dregs), and then removed and drained. Fresh matsutake mushrooms are washed to remove impurities, cut into slices with a thickness of 7mm, blanched in boiling water for 2 minutes, taken out, and washed with 0.1% citric acid, 0.02% ascorbic acid and 0.015% ethylenediaminetetraacetic acid Disodium (EDTA-2Na) is formulated into a compound color protectant solution and soaked for 5 minutes, then remove and drain. The treated purple sweet potato residue and matsutake mushroom slices were placed in a drying oven, the initial temperature was set at 50 °C, and then the temperature was increased by 10 °C ev...

Abstract

The invention belongs to the field of comprehensive utilization of byproducts and development of health-care foods. Purple sweet potato composition nutritional instant powder provided by the invention is prepared from raw materials in percentage by weight: 20%-30% of edible fungi and 70%-80% of purple sweet potato dreg; the purple sweet potato dreg is a byproduct generated in the production of a purple sweet potato pigment; the edible fungi are fresh artificially-planted or wild edible fungi; the purple sweet potato composition nutritional instant powder is ultrafine powder with the average grain diameter which is less than 0.25 microns. A preparation method is composed of following steps: 1, carrying out curing treatment on purple sweet potato dreg raw materials; 2, carrying out color-protecting treatment on the edible fungi; 3, drying; 4, compounding and roughly crushing; and 5, carrying out ultrafine crushing. The purple sweet potato composition nutritional instant powder is produced by combining and matching the purple sweet potato dreg generated by producing the pigment with the edible fungi, so that the aims of complementing the nutrition and strengthening functions are realized and the product has a special flavor; the comprehensive utilization value of the byproduct generated by generated in the production of the purple sweet potato pigment is improved. The purple sweet potato composition nutritional instant powder is produced by adopting an effective color-protecting measure and an ultrafine crushing technology; the product has a very good brewing instant property and keeps nutrition, functional components and flavor of two ingredients.

Description

technical field [0001] The invention belongs to the fields of comprehensive utilization of by-products and development of health food. Background technique [0002] The real name of purple potato is Ipamoea batatas L., which was introduced into my country from Japan. It is a kind of sweet potato with purple or dark purple flesh. Sweet potatoes have anti-cancer and anti-cancer effects. According to the Japanese Cancer Prevention Institute's investigation on the relationship between diet and cancer of 260,000 people, the cancer suppression rates of raw sweet potatoes and cooked sweet potatoes are 94.4% and 98.7% respectively. Among the 17 vegetables that have a significant inhibitory effect on tumors, sweet potato ranks first. The main component of purple potato is carbohydrates (accounting for 80% of dry matter), and its protein is higher than that of ordinary sweet potatoes. The content of trace elements such as lysine, copper, manganese, potassium and zinc in purple sweet...
