Abstract
The invention provides a bread improver and a preparation method and application thereof. The bread improver of the invention comprises the following components in percentage by mass: 0.011 to 0.55 percent of flour gluten fortifier, 0.001 to 0.1 percent of enzyme preparation, 0.5 to 4 percent of emulsifier, 0.5 to 1 percent of calcium sulfate, 15 to 25 percent of wheat gluten and 70 to 83.5 percent of pregelatinized starch. The bread improver of the invention which is 3 to 5 percent of the total mass of the flour can prepare the bread with taste, flavor and shelf life equal to those of recipe bread through a conventional bread preparation process.
Description
Technical field
The present invention relates to a kind of food improver, particularly a kind of bread improver and preparation method thereof and application belong to field of food.
Background technology
Along with the quickening of rapid growth of economy and rhythm of life, deep variation has also taken place in compatriots' diet style.Bakery demonstrates the trend that develops rapidly with its health, delicious food, convenient characteristic since 20 end of the centurys, especially in developed area such as coastal, bakery has become one of important foodstuffs of people's three meals in a day.As one of main kind of bakery, bread also becomes people's current consumption article already, the improving constantly of Along with people's living standard, and the bread of good to eat delicious food more and more is people's favor.
Soup kind bread is that the bread engineer by Japanese Andersen food company improves the baked product of developing according to the manufacture craft of China's traditional food deep-fried twisted dough sticks; The most important technology of this product is to make the soup kind, and the water that is about to 90 ℃ pours in 10~30% flour, makes the abundant gelatinization of starch in the flour; Increase the content of alphalise starch in the flour; The increase of alphalise starch content can delay the aging of flour, optimizes mouthfeel and local flavor, and prolongs storage life.The bread elasticity of using the soup kind to produce is splendid, firmly subdues also after the cooling and can restore to the original state; The long fresh-keeping period of bread can reach 5~7 days; The common texture of loaf in the more current market of bread is fine and smooth, soft, and mouthfeel is better, so one of which occurs just extremely, and the consumer likes.But owing to need to carry out the soup kind earlier, could begin to make bread after the cooling fully again, so the making of soup kind bread is longer than the time of common breadmaking, technology is slightly complicated.People attempt to obtain the New Bread Improver that the common breadmaking technology of a kind of feasible employing can be produced soup kind bread quality bread, to help the production of soup kind bread quality bread.Bread improver in the market mainly increases the volume and the pliability of bread through flour oxidation agent, emulsifying agent and enzyme preparation, but it is limited that product quality is increased degree, can't reach mouthfeel, local flavor and the shelf-life of soup kind bread.Open source literature does not have the relevant report of similar bread improver yet.
Summary of the invention
The shortcoming that primary and foremost purpose of the present invention is to overcome prior art provides a kind of bread improver with not enough.The bread that this bread improver can make commonsense method make reaches mouthfeel, local flavor and the storage life of traditional soup kind bread.
Another object of the present invention is to provide the preparation method of said bread improver.
A purpose more of the present invention is to provide the application of said bread improver.
The object of the invention is realized through following technical proposals: a kind of bread improver is grouped into by following one-tenth by mass percentage:
Flour gluten fortifier 0.011~0.55%
Enzyme preparation 0.001~0.1%
Emulsifying agent 0.5~4%
Calcium sulfate 0.5~1%
Gluten 15~25%
Pre-gelatinized starch 70~83.5%;
Described flour gluten fortifier is preferably at least a in vitamin C, azodicarbonamide or the calper calcium peroxide;
Described flour gluten fortifier is preferably the mixture of a kind of formation in vitamin C and azodicarbonamide or the calper calcium peroxide; Wherein azodicarbonamide or calper calcium peroxide account for 0.001~0.05% of said bread improver quality, and vitamin C accounts for 0.01~0.5% of said bread improver quality;
Described enzyme preparation is at least a in AMS, zytase, lipase or the glucose oxidase;
Described emulsifying agent is at least a in diacetyl tartarate list (two) glyceride (DATEM), stearoyl lactate, CSL, glycerin monostearate or the sucrose fatty ester;
Described pre-gelatinized starch is at least a in preparatory gelatinization cornstarch, pre-pasting potato starch, preparatory gelatinization tapioca or the preparatory gelatinization wheaten starch;
The preparation method of said bread improver; May further comprise the steps: after the calcium sulfate of the azodicarbonamide of mass percent 0.001~0.05% or calper calcium peroxide and mass percent 0.5~1% is mixed again with the enzyme preparation of mass percent 0.01~0.5% vitamin C, mass percent 0.001~0.1%, the emulsifying agent of mass percent 0.5~4%, the Gluten of mass percent 15~25% and the pre-gelatinized starch mixing of mass percent 70~83.5%, obtain bread improver.
Described mixing is mixing in mixer preferably;
Usually mix 25~35min after adding pre-gelatinized starch, can obtain finished product.
When described bread improver is applied to breadmaking, use to be equivalent to 3%~5% of flour gross mass, the breadmaking technology through routine can obtain mouthfeel, local flavor and the shelf-life bread suitable with soup kind bread.
The present invention has following advantage and effect with respect to prior art: use 3%~5% the bread improver of the present invention be equivalent to the flour gross mass, the breadmaking technology through routine can obtain mouthfeel, local flavor and the shelf-life bread suitable with soup kind bread.
