Articles
Mixing is a ubiquitous unit operation within the food industry and employed not only to combine multiple ingredients, but also to control reactions and modify the structure of foods. Failure of the mixing process may result in poor quality, organoleptic or functional attributes of foods along with product safety concerns. The industry is increasingly adopting automation and advanced control strategies such as Process Analytical Technology. Sensors can provide both insights into the complex mechanisms of mixing along with effective control. Here we discuss some recent advances in the control of food mixing operations.

A Slic-Basedsuperpixel Segmentation Method By Using Local Texture Features For Granular Image, Li Xiaoyu, Zhang Qiuju
Food and Machinery
This paper adopts SLIC-based superpixel segmentation method in the granular image detection. SLIC method segments the granular image into superpixel block which will reduce the complexity of the subsequent image processing. As SLIC superpixel segmentation method doesn’t use the texture feature in the distance calculation, the detail of the outline for the granular object is lost. This paper adopts the CRLBP local texture operator as the texture feature to improve the SLIC segmentation’s distance calculation and searches the similar pixel in circle neighborhood pixels to guarantee the processing speed. The test on cotton seed image shows that the improved SLIC …
