Effect of ultrasonic treatment on sucrose inversion in vegetable and fruit purees

Relevance. This article presents the results of a study of the process of sucrose inversion in vegetable and fruit monocomponent purees with and without sucrose under the influence of ultrasonic action on them.

Methods. For the study, experimental samples of carrot, pumpkin and Apple puree of two types were made – a monocomponent natural puree (without sugar) and puree with the addition of 5% sucrose (by weight). The main part of the study was to study the depth of sucrose inversion in experimental samples, depending on the specified parameters of ultrasound exposure at a frequency of 21.6 kHz for 30 minutes on a laboratory cavitation unit in a flow-through cyclic mode.

Results. It was found that in all experimental samples, the amount of total reducing sugars increased significantly compared to the values obtained in control samples that were not subjected to ultrasonic treatment. So, in natural apple puree (without adding sucrose) after ultrasound exposure, an increase in total reducing sugars was detected by 9.3%, and in experimental samples of apple puree with added sucrose – by 10.9%, in relation to control samples, which is 1.2 times higher than in natural puree. In samples of carrot puree (without adding sucrose), the increase in total reducing sugars was 6.7%, and in puree with added sucrose, the increase was 12.2%, which is 1.8 times higher than the inversion in puree without sugar. In samples of pumpkin puree without sugar, the increase in reducing sugars was 4.2%, and in samples with added sucrose – 9.9%, i.e. 2.4 times higher than in samples without sugar.

These data allow us to conclude that ultrasound exposure can intensify the inversion of sucrose with an increase in the number of reducing sugars, and this process takes place more deeply in products containing added sucrose.
