ABSTRACT: Viscose red ginseng extracts dried and coated using fluidized bed coater may broaden their application in food processing industry and increasing the consumer acceptance. The operating conditions of fluidized bed coater were optimized for obtaining high yield and uniform spherical granule. The physicochemical properties and sensory characteristics among the concentrates, the fluidized bed dried core particle and the spherical granules of red ginseng extract were compared. The preservative properties of these materials were also analyzed. The predicted maximum yield of spherical granule was 85.42%, at a feeding rate (FR) of 111.04 mL/min, an atomization air pressure (AP) 275.30 kPa, and a product temperature (PT) of 68.53 °C. Most of ginsenosides, which were known as functional material, did not show significant changes after granulation, while the flowability and water solubility increased. Also, for a 10-mo storage at 30 °C, the spherical granule was the most stable among the materials considered. It can be concluded that the application of fluidized bed coater can be used for making the food product of viscous extracts more valuable. 相似文献

This paper investigates computer vision applications for surface gloss evaluation to determine a quick surface gloss evaluation method for apples. “Red Fuji” apples were wax-coated with different concentrations of shellac solutions to obtain the apple samples with different levels of surface gloss. The surface gloss values and the color scales of the apple samples were detected using a pinhole gloss meter and a color meter. The apple sample images were captured and processed, and the color parameters of the high light areas were extracted. Support vector machine (SVM) regression and classification models were built to predict the surface gloss values and the surface gloss levels of apples, respectively. The results showed that to predict the surface gloss of apple samples, the correlation coefficients of the SVM regression model were 0.94 and 0.90 for the training and the testing groups, respectively. The classification accuracy rates of the SVM classification model for the training and the testing groups were 100 and 96.7%, respectively. Finally, apple surface gloss level classification software was developed, which showed good operating results for both classification accuracy rates and calculation speed. This paper provided a new surface gloss evaluation method based on computer vision for apples. 相似文献
