| Abstract | Strawberries have a short shelf life due to the thin covering tissues, so they easily lose their weight. After harvesting in strawberries, gas exchange processes continue, during which moisture evaporates from the cells, which significantly affects the yield of marketable products. Pre-treatment of berry products with polysaccharides allows to extend the shelf life and slow down metabolic processes. Chitosan is a polysaccharide that has antibacterial properties. The aim of this work was to study the effect of pre-treatment with a solution of chitosan strawberries on the duration of storage and yield of marketable products. To achieve the goal of strawberries after harvest was treated with a solution of chitosan 0,1%; 0,3% and 0,5% concentration and stored in a refrigerator at 0 ± 2 ◦C for 14 days. Untreated berries were used as a control. All experimental studies were performed in triplicate. The results of the study showed that pre-treatment of strawberries with a solution of chitosan can significantly reduce weight loss. In samples that were treated with a solution of chitosan 0.5% concentration of weight loss were the lowest and was 5,5 % at the end of storage, which is 4,5 % less than the control sample. | ||
