A kind of extrusion and puffing food and preparation technology thereof
Technical field
The present invention relates to field of food, more particularly, it relates to a kind of extrusion and puffing food and preparation technology thereof.
Background technology
Cereal extrusion leisure food is to make with cereals raw material corn, wheat, rice, oat, potato, cassava etc.
Raw material, is formed by extruding, seasoning, baking, simultaneously because may bring up barbecue taste, beef flavour, chicken extract taste, fresh shrimp taste etc. during seasoning
Various tastes, can be fabricated to variously-shaped during extruding, such as sheet, pea shape, strip, spherical so that this kind of product same
Production line can produce tens kinds, thus has great development potentiality.Dilated food is being increasingly becoming hundred in recent years
The required consumer goods of surname daily life.The sales volume of the annual leisure food of China reaches tens yuans, wherein corn expanding
The annual production of food about 200,000 tons.A big class as leisure food as can be seen here, cereal dilated food has huge development
Space.
Direct extrusion and puffing food is simple because of process equipment, and yield is big, low production cost and be used widely.It is main
Want technological process as follows:Powder process → batch mixing → extrusion → shaping → baking → seasoning (or coating) → packaging.
ZL200510031839.2 discloses a kind of extruded-puffed potato full-powder food, and this food is sprayed by extrusion billet
Grease and toppings are prepared from, extrusion billet:Grease:Toppings are 1:0.08-0.15:Powdery is first mixed by 0.05-0.15
Described grease and described water is added after stirring, after preparing extrusion billet through extrusion, cutting, baking after being stirred for, spray oil
Fat and toppings are prepared from.
Application number 201310134912.3 is disclosed and a kind of is produced by extruding for raw material with lotus rhizome slag and cornstarch
Dilated food, the dilated food spraying condiment after shaping, drying to moisture packs below 5%.Condiment
Fill a prescription as follows:Seafood taste formula salt the 76%th, monosodium glutamate the 22%th, zanthoxylum powder 2%;Spicy formula chilli powder the 33%th, pepper powder
4%th, refined salt the 48%th, monosodium glutamate the 3%th, five-spice powder 12%;Cumin formula salt the 66%th, cumin powder the 22%th, zanthoxylum powder the 9%th, ginger powder
3%.Its production technology is that flavoring dry powder is directly sprayed on blank surface.
CN1365624A discloses a kind of moisture-proof water-resistant puffed shrimp shreds and compound method thereof.Expanded shrimp cracker sprays edibility
Membrane material, its technical process is as follows:Raw material → mix → add water → stir → be pasted → extrude → be molded → dry → swollen
Change → cooling → spraying → lac → packaging.Spraying film covering method:Expanded rear shrimp cracker is put in the mixer of roller, then will
Lac adds in concentration 15% alcohol, and heating, after temperature 115-120 DEG C is dissolved, is contained in spray gun tank, and spraying 5 minutes overlay films is
Can.
Existing seasoning technique mainly uses grease spraying blank surface, then spills flavoring;Or flavoring is scattered in grease
In (syrup, chocolate mass) be sprayed at blank surface, or directly toppings are sprinkling upon product surface.If above-mentioned technique makes
Add grindings with using syrup, chocolate mass to need, be incubated, the equipment such as smear, increase cost input and energy consumption.
Due to the particularity of extrusion and puffing food processing technology, will through HTHP, some producers by flavoring and
Nutrient adds in compound before extrusion, but seasoning smell is almost vaporized totally after HTHP, vitamin
The nutrients such as A, vitamin E, vitamin D, vitamin C, folic acid vitamin and Cu, Mn, Mo trace element also have largely
Destroy.Further, semi-finished product are no problem in microbiological indicator, but after adding the flavoring of various local flavor, microorganism
Index abruptly increase, is on the one hand ambient influnence in production process, is more that the various flavorings adding contain more microorganism
And be difficult to kill, cause the microorganism of product to exceed standard.Further, grease is used to suck a lot of fat as product during flavoring adhesive
Fat, consumer is a large amount of can cause grease, heat suction to take in too high with being eaten for a long time, and Nutrition intake is not enough, is easily caused obesity.
Meanwhile, product is during storing, and easily becomes sour compared with fattiness rotten, shortens shelf life, causes food-safety problem.Separately
Outward, if toppings are directly sprinkling upon product surface, easily come off, skewness, causes toppings to waste.

As shown in Table 5, contrasting with theoretical values, after discovery spraying, detection data and gross data are without significant difference,
Illustrate that the present invention provides preparation process will not destroy the nutrient of interpolation, almost without loss.
In extrusion pressing puffing process, the change of VC and VA is bigger, and VC loss late reaches 30%, and VA loss late reaches 50%, and cereal is former
Material is the main source of B family vitamin, and VB2 is more stable, and retention is up to 92%, but VB1 retention is only 52%.VE and VD
Unstability due to self, it is easier to the destruction of hot and humid environment.
The present invention uses spraying after expanded molding, it is to avoid various vitamin hot and humid environments destroy, and through compared with low temperature
After spending short time drying, pack.Product storage condition is dried, and does not contains additional fat, will not produce and have oxidizing property
Free radical, ensure that stablizing of within shelf-life nutrient.
