ORGANOLEPTIC EVALUATION OF CANNED SQUASH FOR THE FUNCTIONAL NUTRITION

 

Problem definition. Diseases of the cardiovascular system in the world, including in Ukraine, are considered one of the most common problems of our time [1]. Functional nutrition, that includes the consumption of processed products of squash, belongs to the methods of dealing with them. However, domestic manufacturers produce preservation of these fruits following traditional formulae that do not meet the requirements of consumers.

Analysis of recent researches and publications. The problem of expanding and developing of assortment of preserves that include pumpkin in Ukraine engages à great number of scientist, including T.V. Kravchuk, L.Y. Matenchuk, E.A. Prymachyk, N.O. Stezenko [2, 3]. Abroad the range of products of functional nutrition from the fruits, mentioned above, and certain positive influence of main components on a human body are studied and determined by Martha Fleck [4].

Purpose of the publication. To develop the formulae of conserves of revitalizing direction from squash and to make their organoleptic evaluation. The results of this evaluation determine priority areas of further laboratory tests.

Main part. On the base of the analysis and selection of raw materials, which has the most significant effect on the cardiovascular system of a human body [5], three various kinds of recipes of canned food are designed. As raw materials, the varieties of squash selection of South State Agricultural Experiment Station of the Institute of Water Problems and Land Reclamation of the National Academy of Agricultural Sciences (NAAS PDSDS IVPiM) were used, such as Bylinka, Universal, Gray Ukrainian and a promising variety Stepoviy (table 1, 2). The test specimens were created in the laboratories of the Department of Food Technology of Kherson National Technical University (KNTU).

The evaluation of the developed preserves by organoleptic characteristics was performed by the third- and fourth-year students of direction 6.051701 – "Food Technology and Engineering" KNTU. According to the results (table 3) the greatest number of points (by 5-point scale) was taken by the formula of squash jam with rosehip "Small Heart", that is why the further studying of this range is the most promising.       

Conclusions. According to the results of the organoleptic research of canned squash of new types, it was shown, that the jam recipe, containing rosehip, has the highest average rating. For the conserves "Mystery of the Steppe», it was recommended to improve the formula with a goal to combine the positive impact of canned ingredients on the cardiovascular system of a person with the high tasty qualities.
