Daugelaite, Food Science, UofM, 2014) Lecture outline Introduction Part 1 Sieving, sizing, plansifters Part 2 Air classification, sorting, grading, imaging 2 3 Size sorting is the separation of solids into two or more fractions on the basis of differences in size. It is particularly important when the food is to be heated or cooled (rate of heat transfer; variation in size would cause over-processing or under-processing). Foods with uniform size are preferred by consumers. Screens with either fixed or variable apertures are used for size sorting. The screen may be stationary or, more commonly, rotating or vibrating. Sorting, grading, imaging, air classification 4 Sorting of fruit and vegetables is related in sorting classification Larger potatoes are desirable for long French fries The shape and size of fruit and vegetables should be suitable for handling and processing. Weight sorters are used for valuable foods such as eggs, sensitive fruits, where accuracy in size separation and caution in handling are needed Sorting, grading, imaging, air classification 5 Grading classifies food materials on the basis of commercial value, end usage and standards.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
