Determining a rational hydraulic module to effectively transform pectin substances from watermelon raw materials

The aim of the study is to determine a rational hydromodule for the extraction of water-soluble components from watermelon peels and to assess the proportion of pectin substances in the extract based on the construction of a refractometric scale. Tasks: to construct a refractometric scale to assess the proportion of pectin substances in an aqueous extract using a standard solution depending on the refractive index on an IRF-454 B2M refractometer; to reveal the correlation of the concentration of pectin substances in the aqueous extract from the readings obtained on the IRF-454 B2M refractometer according to the sucrose scale correlated with the refractive index; to experimentally determine a rational hydromodule for the extraction of water-soluble components from watermelon peels. The object of research is watermelon peels (as non-recyclable waste of raw watermelon processing) and pectin extracts from them. A rational hydromodule for the extraction of water-soluble components from watermelon peels was revealed, and the proportion of pectin substances in the extract was estimated on the basis of constructing a refractometric scale. A rational hydromodule for the effective transformation of pectin substances from watermelon raw materials is a practically significant parameter that affects the reduction of material and energy costs when selectively extracting valuable components from vegetable raw materials. The results obtained in the process of research and their practical implementation make it possible to increase the quality indicators of valuable components extracted from watermelon secondary raw materials, as well as the speed of the processes used in technology. For the subsequent analysis and calculation of the duration of the extraction of pectin substances from dispersed watermelon rind with rational process parameters according to the proposed technology, it is necessary to identify the kinetic regularities of this procedure.
