Abstract

The invention provides a production process of puffed corn, and belongs to the field of feed processing. The production process provided by the invention comprises the following steps: firstly uniformly mixing corn with sodium sulfite and salt and crushing, further mixing with a certain proportion of palm oil and a mixture of crab shell powder and citric acid solution, and then puffing. The puffing process is good in effect, low in cost and less in nutrient loss; with the puffing process, the productivity effect can be effectively improved, and the product quality and health security are ensured at the same time.

Description

A kind of manufacturing process of popcorn

Technical field

The manufacturing process that the present invention relates to a kind of popcorn, belongs to field of feed processing.

Background technology

Corn is most important energy source in feed, is called as the king of feed, contains approximately 70% starch in its grain composition.Therefore, improving cornstarch utilization rate is improve livestock and poultry cultivation efficiency of gain and feed efficiency basic.Owing to existing the crystal structure of the antiacid antienzyme of significant proportion to be unfavorable for digesting and assimilating of animal in amylum body, must allow crystal structure disintegrate (be gelatinization, generally use α value representation) could be fully hydrolyzed by enzyme and improve digestibility.Corn puffing can impel the gelatinization degree of starch to improve, and can play the effect of sterilization, sterilizing, increase crude protein, raising gross energy simultaneously, is conducive to increase use value and the utilization rate of corn.

Expanding processing is a feed New Machining Technology, feed is the expanded process that is actually a high-temperature instantaneous in extrusion chamber: in the environment of mixture in high temperature, high pressure and high shear force, high-moisture, by continuously mixed, modified, pressure build up, slaking, extrude nib and suddenly form a kind of feed of bulk porous after step-down.

Puffing material has the utilization rate, the advantage such as pollution, the generation of minimizing disease of reduction to environment that improve feed, along with the development of science and technology and aquaculture, puffing technique is more and more extensive in the utilization of feedstuff industry, and puffing material is also more and more pursued because of its distinctive advantage.Also there is the shortcomings such as cost is high, nutritive loss is large in puffing material simultaneously, particularly the high temperature in puffing process makes a part of reduced sugar in raw material and free amino acid generation Maillard reaction, loss protein and reduced sugar, reduced the utilization rate of protein and reduced sugar.

How reducing the loss that puffing process becomes protein and polysaccharide, reduce a great problem that expanded cost is bulking process, is also a large bottleneck of puffing technique.

Summary of the invention

The object of this invention is to provide a kind of bulking process that can effectively overcome the defects such as corn cost in puffing process is high, nutritive loss is large, this bulking process is effective, cost is low, nutritive loss is few.

A manufacturing process for popcorn, is characterized in that comprising the steps:

Step 1: the corn after impurity elimination and sodium sulfite and salt are pulverized and mixed, cross aperture 0.6-1mm sieve, obtain corn flour stand-by, wherein sodium sulfite content is 0.1-0.3%, and the content of salt is 0.05-0.1%;

Step 2: by corn flour and palm oil in 100:(0.2-0.5) ratio mixes; Add again the mixed liquor of gross mass 0.5-0.8% to mix;

Described mixed liquor: citric acid is made into the solution of 0.5-1%, adds 1-1.5% to cross the crab shell powder of aperture 0.18mm sieve, put into shaking table concussion 30-40 minute, keep temperature 60-80 ℃, obtain mixed liquor;

Step 3: mixed material in step 2 is sent in modified treatment apparatus for bulking machine and carried out steam regulation of texture, conditioning of texture processing, and frequency conversion delivery rate is according to amount of cure and the corresponding adjustment of expanded speed, and steam regulation of texture, conditioning of texture temperature is 90-100 ℃, and steam addition is 8-10%;

Step 4: modified rear material is sent into puffing cavity of puffing machine, and to encircle mould expanded, and swelling temperature is controlled at 120-140 ℃, and pressure is 10-15Mpa, and the time is 25-30 second, screw speed 200-220r/min;

Step 5: cooling, pulverize, packing.

Beneficial effect

In the present invention, pass through the corn of processing, more be conducive to expanded, puffing process is played to facilitation, be conducive to the reduction of expanded cost, the carrying out that can block or slow down Maillard reaction in puffing process, effectively protects amino acid and reduced sugar etc. in corn not to be destroyed simultaneously, is conducive to improve the use value of corn, in addition can also extend the storage period of popcorn, be conducive to reduce the loss of popcorn in storing process; Expanded parameter in the present invention, through inventor's repeatedly debugging, has reached expanded optimal level in addition, can guarantee expanded needs on the one hand, can reduce again on the other hand energy consumption.
