The present research work was carried at the 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 Preparation of Aloe vera pulp powder by using various drying methods with studying changes in the physical quality parameters during drying and storage. The data collected on the physical quality parameters of Aloe vera pulp during drying and storage were statistically analyzed by using Completely Randomized Design (CRD) and Factorial Completely Randomized Design (FCRD) respectively.

Analysis of Aloe vera pulp for different quality parameters during drying such as initial moisture, final moisture, drying time, rate of drying and analysis of storage parameters of Aloe vera powder such as colour and particle size were conducted at 0, 30, 60 and 90 days. During the storage L* value and b* value of colour, decreased with increased in storage period. And a* value of colour was increased with increase in storage period. All the parameters were significantly influenced packaging material and storage time. Particle size 37 micron. Colour value for L*, a* and b* was 39.18, 4.78 and 32.48 respectively.

From overall observation it was concluded that convective tray drying was the best and suitable method for preparation of Aloe vera pulp powder followed by microwave drying, Polytunnel drying and Sun drying. In convective tray drying method 50 °C was suitable temperature for preparing 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.
