Embodiment 1

[0056] 1) Peeling: After washing and peeling fresh potatoes, weigh 100kg and soak in polyphenol oxidase inhibitor for later use;

[0057] In this embodiment, potatoes of the Chabotie variety are used as raw materials, and potatoes without sprouting or greening and pest-free are selected. When peeling, manual peeling or mechanical peeling is used. In this example, a cleaning and peeling machine is used for peeling to increase Efficiency, the liquid dosage of polyphenol oxidase inhibitor during soaking is less than that of potato.

[0058] The composition of the polyphenol oxidase inhibitor is: 0.2 part of citric acid, 0.2 part of ascorbic acid, 0.1 part of hydroxyl reducing agent (cysteine), and 99.5 parts of water. The same formula solution is used for soaking in the color protection step.

[0059] 2) Crushing: use a potato crusher to crush the potatoes into 4cm 3 Left and right pieces

[0060] 3) Color protection: Soak potato pieces in a polyphenol oxidase inhibitor for 8 minutes;

Embodiment 2

[0074] 1) Peeling: After washing and peeling fresh potatoes, weigh 100kg and soak in polyphenol oxidase inhibitor for later use;

[0075] In this embodiment, the green potato No. 2 potato is selected as the raw material, and the potato without sprouting or greening and pest-free is selected. When peeling, manual peeling or mechanical peeling is used. In this example, a washing and peeling machine is used for peeling to increase Efficiency, the liquid dosage of the polyphenol oxidase inhibitor during soaking is less than that of potatoes.

[0076] The composition of the polyphenol oxidase inhibitor is 0.01 part of citric acid, 0.01 part of ascorbic acid, 0.05 part of hydroxyl reducing agent (sodium bisulfite), and 99.93 part of water. The same formula solution is also used for soaking in the color protection step.

[0077] 2) Broken: Break the potato into 5cm 3 Left and right pieces

[0078] 3) Color protection: Soak potato pieces in a polyphenol oxidase inhibitor for 15 minutes;

Abstract

The invention provides potato original juice, original juice drink and a preparation method thereof. The preparation method comprises the following steps: removing peels of potatoes, crushing, carrying out colour protection, pulping, mashing, sterilization, carrying out rapid dehydration, ultrafiltration, nanofiltration and reverse osmosis, and mixing, so that the potato original juice is obtained, and further preparing the potato original juice into the potato original juice drink. The method provided by the invention has the advantages that moisture discharged from the potatoes is further processed into edible potato original juice and the original juice drink while potato flour and starch are produced, and final discharge is purified water, so that the problems that wastewater discharge in the field of potato starch production exceeds standard and the environment is polluted are solved, and the potato original juice drink, taken as novel drink, also can increase economic benefit.

Description

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