Abstract:

This study was carried out to determine the effect of jute and nylon packaging on the nut - kernel dimensions and color characteristics of Tombul and Kara hazelnut varieties and aflatoxin levels during storage. For this purpose, the dimensions, weight, kernel percentage, shell thickness, kernel cavity, good and defective kernel ratio, blanching ratio and some other quality characteristics of the nuts and kernels of hazelnuts stored for one year were investigated. Color scale was obtained by determining the L, a, b, chroma and hue values of natural and roasted hazelnuts. In addition, aflatoxin formation in the samples was monitored during storage. According to the results of the study, it was observed that the packaging difference did not have a significant effect on the nut and kernel dimensions, but it decreased the good kernel ratio of the nylon packaging and increased the defective kernel and blanching rate. Although it is seen that nylon packaging increases the brightness and color saturation, the difference cannot be clearly understood sensory. It was observed that the storage period generally did not affect the nut and kernel dimensions, but decreased the good kernel rate, increased the defective kernel rate and blanching rate, and did not affect the color values at a sensory level. No aflatoxin formation was observed in any of the samples during storage.
