Problems solved by technology

[0002] At present, there are two extraction methods for extracting effective substances from potatoes: ultrafiltration separation and purification separation. However, the purification separation extraction method has good performance and high purity for a single substance, but the extraction cost is high and the process is complicated.
The ultrafiltration separation and extraction method is fast and simple, but the cost is high, the ultrafiltration membrane is expensive, and the extraction cost is high
At present, the above-mentioned extraction method is limited to the preservation and research of the nutritional components of potatoes, and cannot be used for industrial production.
Inexpensive methods for extracting amino acids from potatoes and the use of the extracted amino acids have not yet been studied.

Embodiment 1

[0013] Example 1: A method of extracting amino acid solution from potatoes. Take 200 jin of potatoes and wash them, freeze them at -20°C until the whole potatoes are frozen solid, then thaw the frozen potatoes naturally at room temperature, and then squeeze the thawed potatoes Extruded by a press, centrifuged to extract the supernatant, filtered through filter membranes of different pore sizes, and finally filtered through a 0.22μ filter membrane to obtain the amino acid solution.

Embodiment 2

[0014] Example 2: A method of extracting amino acid solution from potatoes. Take 500 catties of potatoes and wash them, freeze them at -30°C until the whole potatoes are frozen solid, grind them in a homogenizer, take part of the crushed potatoes, thaw them in a water bath at 37°C, and extract them by centrifugation The supernatant was filtered, and finally filtered through a 0.45μ filter membrane to obtain the amino acid solution.

Embodiment 3

[0015] Example 3: A method of extracting amino acid liquid from potatoes, take 300 catties of potatoes and wash them, freeze them at -40°C until the whole potatoes are solidified, thaw them in an incubator at 45°C, and then squeeze the thawed potatoes through an extruder , extract the supernatant by centrifugation, filter through filter membranes of different pore sizes, and filter through a filter membrane of 0.22 μ to obtain an amino acid solution.

Abstract

The invention discloses a method for extracting amino acid from potatoes and an application of an extract thereof. The method comprises the following steps: firstly, taking, cleaning and cooling a potato until the potato is frozen; secondly, unfreezing; thirdly, extruding the unfrozen potato, extracting supernatant fluid or crushing, eccentrically extracting the supernatant fluid, filtering; fourthly, filtering through a filtering film with 0.22 mu or 0.45 mu, and obtaining the amino acid. The method for extracting the amino acid from potatoes is simple and easy, is suitable for industrial production, and has environmental-friendly process; and meanwhile, the extracted material and the residue both have no pollution to the environment.

Description

Technical field: [0001] The invention relates to a method for extracting a liquid containing amino acid from potatoes and the application of the extract. Background technique: [0002] At present, there are two extraction methods for extracting effective substances from potatoes: ultrafiltration separation and purification separation. However, the purification separation extraction method has good performance and high purity for a single substance, but the extraction cost is high and the process is complicated. The ultrafiltration separation and extraction method is fast and simple, but the cost is high, the ultrafiltration membrane is expensive, and the extraction cost is high. At present, the above-mentioned extraction method is limited to the preservation and research of the nutritional components of potatoes, and cannot be industrialized. A low-cost method for extracting amino acids from potatoes and research on the use of the extracted amino acids have not yet been fou...
