The application of the method of multicriteria optimization, the correlation-
regression analysis on the complex of organoleptic and physico-chemical indices made
it possible to rank the varieties: Parthenon, Monaco F1, Belstar F1, Quinta F1 and
determine the most important influencing factors (respiratory intensity, organoleptic
properties, soluble solids content, titrated acids, total sugars content, ascorbic acid) on
the value of the target function, a composite quality index. It is these factors that are
chosen to establish the preservation quality of the cabbage of various varieties. The
obtained data confirm that the freshly picked cabbage broccoli of all grades on the scale
of Harrington's desirability is characterized by a level of “good quality” (Fig. 4).
However, after 5 days of storage only the Parthenon variety retains “good quality”,
while in all the other varieties the quality is reduced to “satisfactory”.
Figure 4. Summary of Harrington's desirability scale
A prognostic model of the quality preservation of broccoli cabbage is developed
depending on the storage duration: y = 4.41 - 0.72x R
2
= 0.889, where y is a complex
quality index, х - duration of storage (days).
The conducted researches make it possible to state the following. The
comprehensive commodity research of broccoli cabbage of Partenon, Monaco F1,
Belstar F1, and Quinta F1 varieties zoned in Ukraine has confirmed its high
organoleptic properties and biological value. In the variety section no significant
differences in the chemical composition have been established except for the content
of ascorbic acid, isothiocyanates, and the intensity of respiration. The method of multi-
criteria optimization has carried out a ranking of grades in quality: Parthenon, Monaco
F1, Belstar F1, Quinta F1. This confirms the possibility of using all the varieties for
canning at low temperatures.
