Powder leakage type fresh keeping powder and preparation method thereof

Abstract

The invention discloses powder leakage type fresh keeping powder and a preparation method thereof. The powder leakage type fresh keeping powder is prepared from mixed starch, edible salt, sodium dehydroacetate, ammonium aluminum sulfate and water through thickening, powder mixing, powder leaking, aging, retrogradation, freezing, powder opening, acid soaking, packaging and sterilization. The prepared fresh keeping powder has the advantages that the curing degree is proper; the toughness is good; strip breaking cannot easily occur; segmented freezing aging is used for treating bean vermicelli; starch molecules can be effectively enabled to have time for directional arrangement; the mouthfeel and the smooth degree of the bean vermicelli are maintained; through powder opening treatment, the vermicelli can be separated; meanwhile, the adhesion occurring during the later-period packaging sterilization is effectively prevented; the product quality is ensured; the shelf life is prolonged; experiments prove that the loss rate of used additives in the preparation process is high; the residual quantity is in a national safety standard range.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a powder-leaking type fresh-keeping powder and a preparation method thereof. Background technique [0002] Vermicelli has a history of more than 1400 years in my country, and it is also an economical food for people to eat three meals a day. It has a huge domestic market and is also very popular in the international market. Sweet potatoes contain a variety of nutrients, commonly known as "earth ginseng", often eaten, have the effects of fitness and disease prevention.

AI Technical Summary

Problems solved by technology

However, due to the lack of relevant standards and mandatory requirements for the current vermicelli production process, different manufacturers have different methods

Traditional vermicelli processing is generally: beating → beating → ripening → silk making → cutting → low-temperature freezing aging → washing / loose powder → metering → forming → drying → packaging → finished product; some manufacturers even add alum, edible Glue and other auxiliary materials are unsafe to eat and unhygienic

The vermicelli produced by the traditional vermicelli production process is not resistant to cooking, easy to burn, and has a poor taste

In addition, the current situation of vermicelli / vermicelli and the difficulty of the industry lie in the short shelf life of the product, which is easily contaminated and corrupted by microorganisms. Later thermal sterilization will cause the exterior of vermicelli / vermicelli to re-cure, resulting in adhesion, poor sensory and edible effects

With the improvement of people's living standards, consumers have higher and higher requirements for food safety. The traditional production process will gradually be eliminated by the market due to the quality of food hygiene.
