Influence of structure-forming recipe ingredients on the quality of pumpkin marmalade

Abstract

Analyzing the assortment of the market for marmalade products, it is worth noting that there is a tendency to introduce natural products in the form of vegetable or fruit puree into the recipe composition, as the demand for confectionery products for therapeutic, prophylactic, and functional purposes, as well as for products with dietary properties, is growing. This work aims to study the influence of structure-forming recipe ingredients on the quality of pumpkin jelly marmalade. Pumpkin puree was used as the primary raw material for producing jelly marmalade, food agar was used as a gelling agent, and natural honey was used as a sweetener. During the study, organoleptic, physicochemical, and microbiological quality indicators of semi-finished pumpkin products and finished marmalade samples were determined. The color assessment of the finished products was carried out using a colorimeter NR-UO (China). Pumpkin semi-finished and finished products meet regulatory documentation requirements regarding organoleptic, physico-chemical, and microbiological quality indicators. When food agar is used as a gelling agent, the degree of color increases due to the transparency of the structure, and the red (+a*) and yellow (+b*) components in samples containing food agar are successfully combined and give the finished product an attractive orange color. To increase the nutritional -value, it is proposed to use cinnamon or coconut flakes, which have beneficial properties, to sprinkle the surface of finished products. The price for 1 kg of pumpkin jelly marmalade was: control sample - 335.46 rubles, “Məkhəbbət” with cinnamon - 748.85 rubles, “Məkhəbbət” with coconut flakes - 725.36 rubles. For a new type of confectionery products, regulatory and technical documentation STO, TI, RC 00493497-005-2022 “Halal” pumpkin jelly marmalade “Məkhəbbət” has been drawn up.
