Abstract

Grape molasses is one of the most popular and traditional food in North Macedonia, mostly used in the past decades. Mainly it’s produced using a traditional protocol (technique) of preparing the molasses, commonly known as "Madzun". The present study summarizes data for characterization of some physical and chemical properties of grape molasses (Madzun) from Vranec grape variety. Comparative analyses have been conducted for samples produced using traditional (four samples) and industrial (one sample) techniques. The water-soluble dry mater contents of the samples were determined in the range from 61.67% to 75.17%. Total sugar contents of the grape molasses (Madzun) samples were determined in the range from: 47.27% to 72.42%. Furthermore, the content of sucrose in all samples was at low levels (<0.1%), which indicates that no sugar, additionally had been added in the production of grape molasses (Madzun). The total phenols expressed as gallic acid were identified in five samples and significant differences were observed between samples. Sensory analysis of the samples was carried out by a committee consisting of 7 members. All committee members were females with long-term experience in sensory evaluation of plant-based foods. The following parameters were evaluated: color, smell, taste, sweetness, acidity, texture and aftertaste. Based on the sensory evaluation data, the highest score of 17.92 points (maximum referent declared value is 20 points) was obtained for V3 sample - the best grape molasses (Madzun) produced using traditional technique.
