Using fruit and berry vegetable powders in tirage toffee production

The aim of research is to study the effect of vegetable powders from the Mespilus berries and rose hips on the quality characteristics of tirage toffee. The objectives of the study are to calculate the recipes for tirage toffee production using vegetable powders; to assess the quality indicators of tirage toffee. The study was carried out in the laboratory of the Department of Chemistry and Methods of the Institute of Food Production of the Krasnoyarsk State Agrarian University. At the first stage, powders were obtained from the berry and rose hips. The second stage consisted in carrying out laboratory tests, where the boiled toffee mass was kneaded (tirage) with a mixture of powders and powdered sugar in the following ratios: Mespilus berries and powdered sugar 50 : 50 (sample No. 1); Mespilus berries and powdered sugar 90: 10 (sample No. 2); rose hips and Mespilus berries 50 : 50 (sample No. 3). In the control sample (“Creamy” toffee), tirage was carried out with powdered sugar according to the classical technology. At the third stage, the analysis of the quality of the samples was carried out in terms of physicochemical and organoleptic indicators. “Creamy” toffee with the use of Mespilus berries and rosehip powders improved the nutritional value of sugar confectionery and reduced its energy value by 1 %. As a result of replacing powdered sugar in the tirage process with a mixture of powdered Mespilus berries and rose hips, toffee was enriched with proteins, vitamins of the group B, iron, manganese, potassium, magnesium. In terms of organoleptic indicators, with the addition of powders, a pleasant fruity taste and smell appear, sample No. 3 becomes softer in structure. The study revealed the appropriateness of using vegetable powders from the Mespilus berries and rose hips in tirage toffee production at 100 % replacement of powdered sugar in a ratio of 50 : 50 to increase the nutritional value, improve the quality and reduce the duration of the tirage stage by 13 %.
