dc.description.abstractThis study was conducted to determine the effect of the different packaging materials for powdered malunggay leaves after 18 weeks of storage at the Crop Processing Laboratory Room of the Agricultural Engineering from August 27, 2008 to January 27, 2009. Specifically, this study aimed to determine the following: (1) the quality and quantity of powdered malunggay leaves using different packaging materials in terms of color and weight, respectively; (2) the best packaging material for powdered malunggay leaves; (3) the Vitamin C content of powdered malunggay after storage; (4) the relationship between temperature and weight after storage; and (5) the relationship between relative humidity and weight after storage.. Four treatments, replicated three times with three samples each, were used with the weight of the samples corrected to compensate for the non-uniformity of the samples obtained. The samples were randomly distributed following the Completely Randomized Design (CRD), with the following parameters: weight before and after storage, color before and after storage and Vitamin C content before and after storage. Analysis of Variance, Single-factor was used to determine whether there was a significant difference among the treatments. Polynomial model and simple linear-regression analysis were used to determine the relationship between the weight of the powdered malunggay and climatic factors (temperature and relative humidity). Results showed that the parameters considered in the study (weight before and after storage; color before and after storage) were not significantly different among the treatments; however, Vitamin C content of the samples after storage significantly differed from the Vitamin C content of the sample before storage. Low temperature and high relative humidity significantly increased the weight of the samples.
