Description

A kind of simple fast, the preparation method of the long steamed bun of shelf life
Technical field
The invention belongs to the food fermentation technical field, especially a kind of simple fast, the preparation method of the long steamed bun of shelf life.
Background technology
China people have the custom of edible wheaten food, and steamed bun be produced on the history in existing more than 2,000 year of China.Comparing maximum difference with the bread in west is the different of mode of heating, because the temperature that steamed bun steams is much lower than the temperature of baking, non-enzymatic browning does not take place basically, can better keep amino acid whose validity.Steamed bun in manufacturing process compared with Western-style pastry can be not outside sugaring and wet goods high heat material, be conducive to healthy.Steamed bun is made classification by it: traditional old face steamed bun, yeast steamed bun and the steamed bun of being made by self-rising flour.
The tradition steamed bun ferment used leaven (or being called introduction, old face, old face juice, leavening dough etc.) be by flour in natural environment with saccharomycetes to make fermentation form.Except the saccharomycete that is in the ascendance, also have other assorted bacterium, such as lactic acid bacteria, it can bring the tart flavour of a kind of fermentation of steamed bun.So in traditional handicraft, will inevitably add a kind of auxiliary material: sodium acid carbonate.Except in and tart flavour, the carbon dioxide that sodium acid carbonate produces in acid-base reaction also plays the effect that makes dough more fluffy.But the amount that adds is few, and steamed bun is tart flavour; The amount that adds is many, and the color and luster of steamed bun will flavescence, can produce an alkali astringent taste youngster simultaneously, and alkali can make that the loss of vitamin B1 causes athlete's foot to cause the health pathology in the dough.In addition, the leaven sweat is slow, generally needs the long period.
The simple saccharomycetes to make fermentation that relies on does not use leaven, can lose full mouthfeel and chewiness that leaven brings steamed bun, and the taste of a kind of " fermentation " is arranged.In addition, too depending on the fermentation of single-activity dry ferment makes cost bigger; If yeast-bitten, the ethanol that yeast produces is oxidized to acetic acid and causes slight tart flavour, can affect the sweet-smelling local flavor of steamed bun.
Contain yeast in the steamed bun self-rising flour, also add a certain proportion of chemical leavening agent.Though it is comparatively convenient that this class additive uses, common people exist suspection to its mouthfeel and security unavoidably.In addition, the price of self-rising flour low unlike active dry yeast.
After steamed bun cooks at normal temperatures the shelf-life very short, especially in summer high temperature season, the shelf-life is no more than 1 day, easily produces food-safety problem.Epsilon-polylysine is a kind of natural homopolymer, and degradable is essential amino acid---lysine in vivo, and it has good fungistatic effect again simultaneously, is a kind of very promising food additives.
By retrieval, find that the patent publication us relevant with present patent application mainly contains:
On October 8th, 1997 by the Decree of Patent Office of China " a kind of fermentation process of steamed bun ", the patent No. is ZL96115740.2, belong to the food fermentation technical field, it is characterized in that: it is made up of " introduction " and two sweats of yeast, with " introduction " fermentation 2~4 hours, add yeast cake again and carry out making living steamed bun behind the secondary fermentation earlier.Though the method and this invention have all been used leaven and yeast, but this patent zymotechnique divided for two stages on the one hand, make fermentation time long partially, and the fermentation of second stage yeast do not play the effect of accelerating the steamed bun fermenting speed, it is unnecessary to seem on the contrary; On the other hand, the fermentation of leaven needs premix flour in the phase I, and has increased filtration step, makes operation bother more.
On June 16th, 2010 by the Decree of Patent Office of China " a kind of old face flavouring agent and preparation method thereof ", application number is 200810177094.4, it is characterized in that the old face flavouring agent of preparation earlier: make behind the old face dough that ferments is dry and be ground into particle by the steamed bun fermentation, and add a little dietary alkali.Again batchings such as old face flavouring agent combining yeast are produced steamed bun.Though culture propagation and old face fermentation advantage have separately also been considered in this invention, this invention old face of drying and crushing in advance prepares old face flavouring agent, and operation is too complicated, is different with directly using leaven to leaven dough in this invention.
