Novel energy-saving cryogenic equipment for walnut kernel peeling
In a recent study, a prototype cryogenic equipment was designed to peel walnut kernel more efficiently than by immersion in liquid nitrogen.
In the food industry, walnut kernels are used in baking, pastry and confectionery as well as for flavouring drinks and ice creams. The peeling of the skin coating the walnut kernel is a value-added first step before any further processing. This process reduces the tannin content, thus improving ...
