Embodiment 1

[0046] 1) Peeling: After washing and peeling the fresh potatoes, weigh 100 kg and soak them in polyphenol oxidase inhibitors for later use;

[0047] In the present embodiment, the potatoes of the Fewruit variety are selected as raw materials, and potatoes without germination or greening and without insect damage are selected. Manual peeling or mechanical peeling are used when peeling. In the present embodiment, a cleaning and peeling machine is used for peeling. To increase efficiency, the liquid dosage of polyphenol oxidase inhibitor should not exceed the amount of potatoes when soaking.

[0048] The composition of the polyphenol oxidase inhibitor is: 0.2 parts of citric acid, 0.2 parts of ascorbic acid, 0.1 parts of a hydroxyl reducing agent (cysteine), and 99.5 parts of water. The same formula solution is also used for soaking in the color protection step.

[0049] 2) Crushing: the potatoes are broken into 4cm using a potato crusher 3 left and right fragments;

Embodiment 2

[0059] 1) Peeling: After washing and peeling the fresh potatoes, weigh 100 kg and soak them in polyphenol oxidase inhibitors for later use;

[0060] Select Qingshu No. 2 potatoes as raw materials in this embodiment, select potatoes without germination or greening, and no pests, and use manual peeling or mechanical peeling when peeling. In this embodiment, use a cleaning and peeling machine to peel to increase Efficiency, when soaking, the liquid dosage of polyphenol oxidase inhibitor can be no more than no more than no potatoes.

[0061] The composition of the polyphenol oxidase inhibitor is: 0.01 part of citric acid, 0.01 part of ascorbic acid, 0.05 part of a hydroxyl reducing agent (sodium bisulfite), and 99.93 parts of water. The same formula solution is also used for soaking in the color protection step.

[0062] 2) Crush: Crush the potato into 5cm 3 left and right fragments;

[0063] 3) Color protection: Soak potato pieces in polyphenol oxidase inhibitor for 15 minutes...

Abstract

The invention provides a preparation method of potato-derived purified water. The potato-derived purified water is obtained by removing peel of potatoes, crushing, carrying out color protection, pulping, sterilizing, and carrying out high-speed dehydration, ultrafiltration, nanofiltration and reverse osmosis. After the method is used, water discharged out from the potatoes is further processed into drinkable potato-derived purified water while potato flour and starch are produced; the potato-derived purified water can be both used as human and animal drinking water and industrial water, so that a new way for creating economic benefit is opened up for the field of potato deep processing.

Description

technical field [0001] The invention belongs to the technical field of food processing, and relates to a potato deep processing technology, in particular to a potato source purified water and a preparation method thereof. Background technique [0002] Potato (scientific name: Solanum tuberosum, English: potato), Solanaceae Solanum, an annual herb plant, also known as ground egg, potato, potato, yam egg, sweet potato, potato, steamed egg, etc. Among the ingredients of potatoes, starch is 9-20%, protein is 1.5-2.3%, fat is 0.1-1.1%, crude fiber is 0.6-0.8%, and the rest is water. Because potatoes have good nutritional value and economic value, they are widely used in food industry, starch industry, feed industry and pharmaceutical industry. At present, my country's potato planting area and total output have jumped to the first place in the world, and its consumption is also one of the fastest growing countries in the world. Although my country has become a big potato product...
