Problems solved by technology

[0003] The peeling step will be used in the potato processing technology. The existing peeling process is to use a manual knife to peel or use a peeling machine to peel, but no matter which peeling method is used, it will cause the peeling process. During the process, part of the potato stems will be peeled off at the same time, resulting in a large ...

Embodiment 1

[0042] Use a cleaning machine to clean 100 freshly selected potatoes for the first time. After the first cleaning for 10 minutes, perform the second cleaning, and then put the cleaned potatoes into the cleaning cavity of the large ultrasonic cleaning machine and clean them Pour a solution containing KOH with a mass fraction of 6% and ethanol with a volume percentage of 90% into the chamber. Under the conditions of a solution temperature of 75°C and an ultrasonic frequency of 20KHz, the skin is removed by stirring at 60r / min for 6min to obtain the epidermal residual rate For 0% peeled potatoes, the remaining skin ratio refers to the number of potatoes with skin remaining on the potato compared to the total number of potatoes.

[0043] After the peeling is completed, remove the potato peels, and discharge the peeling solution in the cleaning cavity, and then pour into the cleaning cavity containing 7% citric acid, 3% ascorbic acid and 0.5% glutathione. The aqueous solution of th...

Embodiment 2

[0046] Use a cleaning machine to clean 100 freshly selected potatoes for the first time. After the first cleaning for 10 minutes, perform the second cleaning, and then put the cleaned potatoes into the cleaning cavity of the large ultrasonic cleaning machine and clean them Pour a solution containing KOH with a mass fraction of 8% and ethanol with a volume percentage of 70% into the cavity. Under the conditions of a solution temperature of 65°C and an ultrasonic frequency of 40KHz, the skin is removed by stirring at 70r / min for 7min to obtain the epidermal residual rate For 1% of peeled potatoes, the remaining skin ratio refers to the number of potatoes with skin remaining on the potato compared to the total number of potatoes.

[0047] After the peeling is completed, remove the potato skins, and drain the peeling solution in the cleaning cavity, and then pour the solution containing 3% citric acid, 7% ascorbic acid and 1% glutathione into the cleaning cavity. The aqueous solut...

Embodiment 3

[0051] Use a cleaning machine to clean 100 freshly selected potatoes for the first time. After the first cleaning for 10 minutes, perform the second cleaning, and then put the cleaned potatoes into the cleaning cavity of the large ultrasonic cleaning machine and clean them Pour a solution containing 7% KOH by mass fraction and 80% ethanol by volume into the cavity, and remove the skin under stirring at 65r / min for 10min at a solution temperature of 70°C and an ultrasonic frequency of 30KHz to obtain the epidermal residual rate For 2% peeled potatoes, the skin residual ratio refers to the number of potatoes with skin remaining on the potato compared to the total number of potatoes.

[0052] After the peeling is completed, remove the potato peels, and discharge the peeling solution in the cleaning cavity, and then pour into the cleaning cavity containing 5% citric acid, 5% ascorbic acid and 0.7% glutathione. The aqueous solution of the polyphenol oxidase inhibitor is soaked for ...

Abstract

The invention provides a potato pulp preparation method and potato pulp prepared by the same, and relates to the field of processing of fresh potatoes. The preparation method comprises the following steps: pouring a solution which contains KOH with mass concentration of 6-8% and ethanol with volume percentage of 70-90% in an ultrasonic washing machine; stirring for 5-10 min at the temperature of 65-75 DEG C to obtain peeled potatoes; soaking the peeled potatoes by using an aqueous solution of a polyphenol oxidase inhibitor which contains citric acid with mass concentration of 3-7%, ascorbic acid with mass concentration of 3-7% and glutathione with mass concentration of 0.5-1% to dealkalize the potatoes so as to obtain the dealkalized potatoes; and grinding the dealkalized potatoes into the potato pulp. In the preparation method, peeling efficiency is high, peel residues are less, alkaloid in the potatoes is removed, activity of the polyphenol oxidase is inhibited, and freshness of the potato pulp is guaranteed.

Description

technical field [0001] The invention relates to the field of fresh potato processing, and in particular to a method for preparing potato pulp and potato pulp prepared therefrom. Background technique [0002] Potato (scientific name: Solanum tuberosum), Solanaceae Solanum, an annual herb, also known as ground egg, potato, potato, etc. Potatoes are propagated from tubers and can be used as medicine. They are flat in nature and sweet in taste, and can treat stomach problems, carbuncles, etc. Generally, fresh potatoes contain nutrients such as starch, protein, fat, crude fiber, carotene, and ascorbic acid. Among them, the content of ascorbic acid and various minerals contained in potatoes is much higher than that of apples, and potatoes can be eaten in daily life to supplement ascorbic acid and various minerals needed by the human body. [0003] The peeling step will be used in the potato processing technology. The existing peeling process is to use a manual knife to peel or u...
