10 testers are found, after allowing each tester to observe respectively and eating 8 kinds of niblets, to the processing quality and mouthfeel of niblet
It scores, full marks are 100 points, and statistical data obtains following table:
28 kinds of niblet mouthfeels marking tables of table
38 kinds of niblet processing qualities marking tables of table
By the data in table 2-3, it is apparent that by high pressure curing, ultrasonic immersing and vacuum and low temperature in the present invention
The niblet of oil bath dehydration processing is obviously than without high pressure curing and without the mouthfeel of the niblet of ultrasonic immersing processing
Good, processing quality (including color and plumpness) is high, also, the gelatinization degree by accurately controlling processed niblet is high, aqueous
Rate is low, by accurately controlling the niblet mouthfeel being process and processing quality obviously than the niblet mouthfeel of other embodiments
Good, processing quality is high, therefore, has processing quality good by accurately controlling the niblet that processing conditions is process, processing effect
The high advantage of rate.
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily
Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously unlimited
In specific details and shown here as with description embodiment.
