Abstract:
The present research work was carried at department of PHM of MAPSF of PGI PHM Killa, Roha, Dist. Raigad, (Dr. B. S. K. K. V., Dapoli, Dist. Ratnagiri) Maharashtra. India, during the year 2020-21. The main objective of the research was to study the changes in chemical quality parameters of Aloe vera pulp powder prepared by different drying methods during storage. Which evaluates chemical properties and storage stability of Aloe vera pulp powder. By using convective tray drying method at 50^◦ C made the good quality powder with better shelf life. Standardized powder was packed in polyethylene bags. Aloe vera pulp powder was kept at room temperature for further storage studies after packaging. Aloe vera pulp powder for analyzing with different quality parameters during storage were conducted at 0, 30, 60 and 90 days. During the storage total ash, titrable acidity, fat, protein, fiber and solubility decreased with increase in storage period. The, TSS, moisture content, pH were increased with increase in storage period. All the parameters were significantly influenced packaging material and storage time. In the process of preparation of Aloe vera pulp powder by different drying methods, convective tray drying method gave significant results. In chemical parameters total ash was 14.08%, titrable acidity 0.47%, fat 2.16%, protein 4.18%, fiber 16.54%, pH 4.31, TSS 4.50 ⁰Brix, moisture content 3.85% and solubility 3.16 minute respectively. From overall observation it was concluded that convective tray drying was the suitable method for preparation of Aloe vera pulp powder followed by microwave drying, Polytunnel drying and Sun drying. In convective tray drying at 50 °C was suitable temperature for preparation of Aloe vera pulp powder and it was stored for 90 days at room temperature without affecting its quality and also found suitable for human consumption.
