BIOMETRIC CHARACTERISTICS OF CORYLUS AVELLANA NUTS GROWN IN ALMATY REGION

Hazelnuts are one of the most popular nuts consumed by people. Among dried fruits, the cultivation of hazelnuts occupies one of the first places. Based on this consideration, it was decided to check whether the great commercial value of this fruit corresponds to an equally dynamic and productive development of scientific activity. The purpose of this study was to characterize some of the physical and mechanical characteristics, features of the form of hazelnut varieties grown in the South-East of Kazakhstan. In recent years, researchers have mainly focused on the physical properties of agricultural products to study the relationship between and between physical and chemical parameters. For agricultural products, appearance, shape and size are important parameters. The physical properties of agricultural commodities are largely used in various processes and operations such as storage, classification, drying, packaging, sizing and transportation of these products. The shape and size properties of the samples were determined using conventional measurement methods. Measurements were made on 80 randomly selected hazelnuts, 10 hazelnuts from each tree. Hazelnuts were collected in 2020 in the Ile-Alatau National Park in nursery number 1, which is located in the Almaty region. The collected fruits are immediately transferred to the laboratory. Nut samples were dried to a standard moisture content before being analyzed and measured in the laboratory. The novelty lies in the fact that biometric data of the Corrylus Avellana species outside the natural habitat has not been described before. At the same time, the research was focused not only on production in the field, but also on the study and improvement of product quality. Thanks to the analysis, it was possible to trace some future research directions for this relatively little-studied topic.
