The influence of food coatings on the microbiological state of walnut kernel

Abstract

Walnuts (Juglans regia L.) are widespread throughout the world. This paper compares the effect of food-based coatings based on serum protein and gelatinous isolate on the microbiological state of the nut kernels surface. For the purity of the experiment, two methods were used for all samples: deep and surface seeding. At the same time, it is possible to note the relationship between the number of germinated colonies, the type of coverage and the time of storage of the kernel.
