Abstract

The invention discloses a preparation method of a vacuum frozen-dried potato noodle. The preparation method comprises the following steps: step one, making a raw noodle, wherein the raw materials for making the noodle comprise the following materials in parts by weight: 45-55 parts of flour, 40-50 parts of potato whole powder, 2-6 parts of gluten flour, 1.0-2.5 parts of table salt and 30-40 parts of water; step two, well cooking the raw noodle; step three, pre-freezing, namely freezing the cooked noodle in a mold for 1-5 hours until the cooked noodle is shaped; and step four, vacuum freezing and drying, namely placing the pre-frozen cooked noodle in a vacuum freezing and drying device to dry the pre-frozen cooked noodle until the water activity is smaller than 0.6, wherein the temperature of the cold trap is -40 DEG C to -20 DEG C, the temperature of the shelf is -45 DEG C to -25 DEG C and the vacuum degree is 10Pa-100Pa. According to the preparation method of vacuum frozen-dried potato noodle, the cooked noodle is processed by the vacuum freezing and drying technology, so that nutrient loss is relatively low; moreover, the interior of the noodle is loose and porous, so that water absorption property of the noodle is improved, the rehydration time of the noodle is shortened and the high-temperature frying process is saved. The potato whole powder is added in the vacuum frozen-dried potato noodle, so that the nutrient value of the noodle is increased. The noodle prepared by the preparation method has the characteristics of convenience, tasty flavor and rich nutrients.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a vacuum-frozen potato noodle and a preparation method thereof, and also relates to an instant food containing the potato noodle. Background technique [0002] With its advantages of convenience and quickness, instant noodles have become the largest and most popular staple food in the world today. However, there are great health risks in instant noodles. It has a high oil content, and high-temperature frying may produce carcinogen acrylamide, which is very harmful to the human body. Non-fried convenience food has no high-temperature frying process, which avoids the production of carcinogenic acrylamide. [0003] Potatoes have high nutritional value, comprehensive nutrition, high digestible components, easy to be absorbed by the human body, and the quality is similar to animal protein, comparable to eggs. However, there are quite few types of food made from potatoes, which cannot s...
