COMMODITY EVALUATION OF RAMBUTAN (NEPHELIUM LAPPACEUM L.) 

Background. In recent years, the Ukrainian market is saturated with a wide range of tropical and subtropical fruits: papaya, mango, passion fruit, avocado, pitahaya, lychee, pomelo, mangosteen, kumquat, carambola, rambutan, kiwano, tamarillo, pepino, etc., which gradually become an indispensable attribute of the diet of compatriots. Limited information on consumption properties, storage conditions, quality criteria, peculiarities of consumption of different types of exotic fruits adversely affect the increase in consumer demand for them, although its market is quite promising and in the near future it is expected to grow. One of the types of exotic fruits presented on the Ukrainian market is rambutan which comes from Southeast Asia and is also cultivated in South Asia, Equatorial Africa and Central America, Australia.
The aim of this study is a study of changes in the consumption properties of rambutan by a complex of organoleptic and physicochemical indicators of quality.
Materials and methodsThe object of study is rambutan (Nephelium lappaceum L.)of the country of origin of Vietnam, which is marketed in Auchan.
Results. It was found that during the first 5 days of storage in the trading hall, the weight loss of rambutan fruits gradually increased due to the evaporation of moisture and amounted to 8.27 % on the 5th day. On the 15th day of storage they increased to 34.78 %, which negatively affected the appearance of the fruit.
Conclusion. During storage, changes in the consumption properties of rambutan occur, which is characteristic for products of plant origin, in which physical, chemical, biochemical, microbiological processes continue to occur. A significant reduction in the consumption properties of rambutan fruits is set for 15 days of storage, which does not correspond to the length of storage recommended by the manufacturer.

Keywords: rambutan, quality indicators, consumer properties, weight loss, storage duration.
