Embodiment 1

[0039] 1. Screening and grading: First, remove impurities or unqualified corn from the corn raw material, and then classify the corn according to the size, and divide it into two to three grades according to the situation of the corn raw material. Try to make the corn kernels of the same grade basically the same size to ensure The time required for each subsequent process is the same, and the puffing of the product is consistent, so as to prevent the phenomenon that the small corn kernels are easy to burn when puffing or frying, and the large ones may be insufficiently puffed or not fried thoroughly, which is conducive to the stability of the product. and energy saving.

[0040] 2. Cooking: Put the corn with uniform size after removing impurities into the pot, add water twice the weight of the raw material, boil for 150 minutes, clean and sterilize the corn, and gelatinize and denature the starch in the corn.

[0041] 3. Drying: Dry the cooked corn kernels with hot air, becaus...

Abstract

The invention provides a preparation method of expanded popcorn. The method comprises the following steps: selecting materials; removing impurities; grading corn kernels through screening, wherein the corn kernels are divided into 2-3 grades according to sizes of the corn kernels; boiling: putting impurity-removed corn kernels with uniform sizes in the same grade in a pot, adding water of which the weight is 1.5-2.5 times of the weight of the raw materials, and heating and boiling the water for 120-150 minutes; draining the boiled corn kernels, and drying the corn kernels until the water content of the corn kernels is reduced to 10.5-14%; expanding the obtained dry corn kernels; screening the corn kernels; putting the screened corn kernels in oil with the temperature of 180-190 DEG C for frying for 55-65 seconds; flavoring the fried corn kernels; and carrying out microwave drying on the flavored corn kernels until the water content of the corn kernels is reduced to be within 3%, thereby obtaining the expanded popcorn. The method provided by the invention lowers the temperature, shortens the time, reduces the nutrient loss, reduces the energy consumption and reduces the production cost, the product has good mouthfeel, and the shelf life is prolonged.

Description

technical field [0001] The invention relates to the technical field of food, and more specifically relates to a preparation method of puffed popcorn and its products. Background technique [0002] Zeatin has the reputation of longevity food, rich in protein, fat, vitamins, trace elements, cellulose and polysaccharides, etc., and has great potential to develop high nutrition and high biological function food. Its nutritional value exceeds that of flour and rice, and regular consumption can prevent diseases such as arteriosclerosis, cardiovascular and cerebrovascular diseases, cancer, hypercholesterolemia, and high blood pressure. But corn is now mainly used as feed or industrial raw material, and it is far less popular than wheat and rice as direct food or as food processing raw material. The main reason is that corn has a poor taste. The puffed corn kernels refer to the use of corn as raw material to expand the volume of the corn to several times that of the original corn k...
