The present invention is achieved in that a kind of production method of puffed instant oats particles, the steps include: 1, selects materials, and selects excellent naked oats for use, impurity and band shell rate＜3%, moisture content＜13%, protein＞15%; 2, clean airing, use saline sook, remove and be with the shell wheat, selected then removal wheat husk, with washing the wheat drier or manually clean raw material, and the oat airing after will cleaning; 3, adjust moisture, the water content of clean oat is adjusted to 10～12%; 4, extrusion, with clean oat input single screw squeezing expansion machine, the screw rod blade and the machine barrel of rotation push and shear oat, the oat temperature is raise cure into pastel, and pastel is extruded volumetric expansion from the moulding hole on the template; 5, sterilization packaging,
2, health testing result: to pathogenic entero becteria, the mPV total plate count detects, and sees Table 2
Table 2
| Actual detecting | Minimum limit value | |||||
| The sample title | Total plate count | mPV | Pathogenic entero becteria | Total plate count | mPV | Pathogenic entero becteria |
| Puffed instant oats particles | ＜10/g | ＜30/100g | Do not find | ＜750/g | ≤ 30/100g | Must not detect |
Because material at extrusion pressing puffing process, has passed through the high-temperature maturing effect, has played bactericidal action.
3, shelf characteric test: swollen instant oats particles and quick oatmeal were stored 28 days in 37 ℃ insulating box respectively, after measured: the fatty acid value of puffed instant oats particles has increased by 3.9%, reach 100.8mgKOH/100g, the sensory evaluation smell has the fragrant of oat; And the fatty acid value of oatmeal has increased by 88.8% fast, reaches 709.2mgKOH/100g, and the sensory evaluation smell has rancidity.
The shelf characteric of puffed instant oats particles is than stable many of quick oatmeal.
4, reconstitute the performance contrast:
Puffed instant oats particles: need not boiling, the boiling water that usefulness is＞90 ℃ brew and were thick in 1～2 minute, i.e. edible.
Quick oatmeal: boiling need be arranged in the boiling water 3～5 minutes, be thick, can eat.
The brew of puffed instant oats particles is better than quick oatmeal.
5, product quality height, digestibility is good
Puffing process in the production method of the present invention is that its process of a PTST process (maturing process of high temperature, short time) has reduced the food nutrient composition degradation that is caused by heating to greatest extent, by starch gel gel and protein-modified, improved digestibility simultaneously.
Non-limiting examples of the present invention:
A kind of production method of puffed instant oats particles
1, selects materials: select excellent naked oats for use, control impure and band shell rate＜3%, moisture＜13%, protein＞15%;
2, cleaning: artificial or machinery is removed impurity, sandstone, scum etc., removes most of band shell oat with saline sook, needs artificial essence to move at last and removes band shell oat and wheat husk;
3, clean airing: with washing the wheat drier or manually clean raw material, and with the oat airing that cleans up;
