Processing technology and formulation of quality standards for Massa Medicata Fermentata fried with bran
Objective To optimize the processing technology of bran-fried Massa Medicata Fermentata and establish its quality standards.Methods Taking color and odor as evaluation indicators,and extract as the reference,the factors stir frying temperature,stir frying time and bran addition were investigated by the single factor experiment to optimize the processing technology of bran-fried Massa Medicata Fermentata.A total of 15 batches of Massa Medicata Fermentata were produced by three enterprises in Shanxi province with stir-fried with bran.The characteristics,the microscopic identification,the contents of moisture,ash and insoluble ash,and the extract of processed products were investigated to establish the corresponding quality standards.Results The optimal processing technology of bran-fried Massa Medicata Fermentata was as follows:stir frying temperature of 130℃,stir frying time of 12 min,and bran addition of 10%.After the optimal processing technology,the bran-fried Massa Medicata Fermentata was light brown to yellow brown on the surface,and crispy in texture,with a bran aroma,and the extract content was 22.26%.The qualified bran-fried Massa Medicata Fermentata had a brownish yellow color on the surface,a tough and crispy texture,and a wheat bran aroma;and it was easy to break,and had uneven cross-section,visible brown residue and gaps after fermentation.Microscopical results showed that the epidermal cells of the fruit peel of wheat bran were tightly arranged in an irregular sheet shape;starch granules were spherical in shape with obvious layering;the stone cells of bitter almonds and red beans were yellow or white in color,with black cell cavities;the grid-like cell lumen of the seed coat of adzuki bean contained a light reddish brown substance,with a clear brilliant band.The moisture content should not exceed 10.0%,the ash content should not exceed 5.0%,the acid insoluble ash content should not exceed 2.0%,and the extract should not be less than 17%.Conclusion The processing technology and the quality standards of bran-fried Massa Medicata Fermentata have been established,which can provide the reference for the production and the quality control of bran-fried Massa Medicata Fermentata decoction pieces.
