The bean puffed food obtained by the preferred embodiment has fine and smooth mouthfeel, is instantly melted in the mouth, is fluffy and crisp, and has no beany flavor of soybeans.
Example 5
The control group only used soybean as raw material, and no corn and peanut;
this example is essentially the same as example 2, except that no corn or peanut is used in the feed.
Product evaluation:
in the present example, it was difficult to obtain puffed soybeans, and a small portion of the puffed soybeans had a hard, slightly crispy, chewy, and beany flavor.
Example 6
The water content of the control group after drying in the step (2) is 10 percent;
this example is substantially the same as example 3 except that the moisture after drying in step (2) was 10%.
Product evaluation:
the soybean puffed food obtained in the embodiment has the advantages that due to low moisture, when soybeans are puffed for the first time, straight chains of the soybeans are difficult to fully convert into branched chains, the product puffing effect is poor, the taste is rough and hard, the texture of the product is strong, and the product has toughness (the chewing feeling is strong and the product is difficult to chew and crush), and the soybean puffed food has no beany flavor.
Example 7
The water content of the control group after drying in the step (2) is 20 percent;
this example is substantially the same as example 3 except that the moisture after drying in step (2) was 20%.
Product evaluation:
the puffed bean food obtained in the embodiment is too fluffy, is just melted in the mouth, has no crispness, is sticky to teeth, and has no beany flavor of soybeans.
Due to high water content, when the soybean is puffed, the soybean is cracked into starch with smaller molecular weight and low sugar substances, thereby influencing crispness and tooth adhesion.
