Description
Technical field
The present invention relates to noodles and its production methods.
Background technology
Noodles are one of traditional staple foods of many Asian countries, away from the modern history for having more than 4,000 years.Vermicelli are that China is each
The traditional grain product that output is maximum in class noodles, sales range is most wide, it is deep by consumer when being convenient for storing and transport
With the welcome of manufacturer.Vermicelli are to dry made fresh noodles, and making its final moisture content, this causes in 10%-12%
Noodles shelf life is long, easily stored, but also causes brew time relatively long, by taking thickness is the vermicelli of 0.9mm as an example, when cooking noodles
Between usually in 5-6min.With people's the accelerating rhythm of life, the characteristics of vermicelli brew time is partially long, all the more receives consumer
Conflict.
Vermicelli brew time grows the drying process for being mostly derived from vermicelli.In vermicelli drying process, interiors of products stomata reduces,
This so that in boiling process that moisture is slow from surface to noodles center diffusion velocity, and vermicelli brew time is with respect to made fresh noodles
It is apparent elongated;In addition, cooking for a long time, also result in noodles surface noodles central part when excessively cooking tacky and but not yet fill
Divide and be cooked, this also affects the mouthfeel of noodles to a certain extent.At present, domestic and international researcher is main for the research of fast ripe vermicelli
In terms of the pre-gelatinized for concentrating on dough and noodles drying link, such as microwave heating and infra-red drying technology, the practical behaviour of these technologies
Make it is cumbersome, applied to actual industrial metaplasia production still acquire a certain degree of difficulty.
Vermicelli color and luster is one of leading indicator of consumer's concern, and the higher vermicelli of whiteness are often popular with consumers again;
However, the main flour for planting wheat breed Chinese at present is averaged, whiteness is relatively low (74.8), is especially the absence of the high strong gluten wheat of whiteness
Kind, made vermicelli color and luster is dark, this is the basic fundamental demand that industry faces.It is brightened about noodles, mostly using chemistry
Brightening agent and enzyme preparation;Common brightening agent benzoyl peroxide is a kind of colourless or white crystals or powder, main function are
It is combined with the water in dough and releases active oxygen, the substances such as oxygenated carotenoid make flour bleach, and the substance is because of unsoundness
Risk does not allow to use in flour at present;Biological enzyme formulation class has lipase, alpha-amylase, zytase etc., however,
Enzyme preparation higher price adds somewhat to the cost of material of vermicelli.
Fresh flour is the traditional form of noodles, the techniques such as non-drying or frying, fresh, face it is aromatic it is strongly fragrant, mouthfeel is good, food
It is very popular with convenience.However, the moisture of noodles has just been made in 32%-38% (water activities>0.95), room
Temperature is lower when placing, and easily sticks together, is brown stain, rancid and go mouldy, and pole not storage endurance, this becomes the bottle of its industrialized production
Neck, and Restrain browning and it is fresh-keeping also become fresh flour industrialized production urgent problem to be solved.At present, a big chunk fresh flour
Still from individual workship, sanitary condition and product quality are all difficult to ensure that, it is difficult to meet consumer to healthy and sense organ
Demand.
Inhibiting the method for fresh flour quality deterioration mainly has addition preservative, reduces water activity, heat treatment sterilization, cold place
Manage the compound use of sterilization, controlled atmospheric packing etc. and the above method.Although addition preservative and reduction water activity can inhibit
Quality deterioration, but also increases the use of food additives, reduces the natural attribute of fresh flour to a certain extent;Heat treatment and
Cold treatment sterilization technology also produces noodle quality some deleterious effects while sterilization, such as color and luster variation, mouthfeel not
Good, face fragrance reduction etc.;Controlled atmospheric packing need to usually be used in combination with other technologies could generate good fresh-keeping effect.
Therefore, this field still needs the improved method of production noodles, fresh flour brown stain and microorganism effectively to be inhibited to give birth to
It is long, extend the shelf life of noodles, improve the whiteness of vermicelli, reduce the brew time of vermicelli.
