Azolla pinnata is a small floating plant that is rich in protein and other nutrients and is suitable for livestock feed. Drying is one of the traditional techniques to preserve food to stay longer in shelf life, besides it is the easiest way and can help in maintaining the properties of the plant or food. There is a lack of information on the physical properties of Azolla pinnata in powder condition. In this study, four different combinations of two drying methods using shade drying as a control variable and oven drying at different temperatures at 40°C, 50°C, and 60°C as the test variable on grinded and non-grinded Azolla were performed. The objective of the study was to determine the effects of different drying methods on the physical properties of Azolla powder containing either grinded or non-grinded Azolla. The results obtained of tapped density, bulk density, Carr's Index (CI), and Hausner ratio values were recorded in Table 1. Based on Table 1, the good value of powder flowability was determined by the values of CI and Hausner ratio. According to results obtained, oven drying at 50°C provided the most suitable drying method to be used because it provides good physical characteristics, especially for grinded Azolla powder.

Abstract

Azolla pinnata is a small floating plant that is rich in protein and other nutrients and is suitable for livestock feed. Drying is one of the traditional techniques to preserve food to stay longer in shelf life, besides it is the easiest way and can help in maintaining the properties of the plant or food. There is a lack of information on the physical properties of Azolla pinnata in powder condition. In this study, four different combinations of two drying methods using shade drying as a control variable and oven drying at different temperatures at 40°C, 50°C, and 60°C as the test variable on grinded and non-grinded Azolla were performed. The objective of the study was to determine the effects of different drying methods on the physical properties of Azolla powder containing either grinded or non-grinded Azolla. The results obtained of tapped density, bulk density, Carr's Index (CI), and Hausner ratio values were recorded in Table 1. Based on Table 1, the good value of powder flowability was determined by the values of CI and Hausner ratio. According to results obtained, oven drying at 50°C provided the most suitable drying method to be used because it provides good physical characteristics, especially for grinded Azolla powder.
