Physicochemical Properties Analysis of Three Indexes Pineapple (Ananas Comosus) Peel Extract Variety N36

Pineapple peel is a major waste in pineapple canning industry. It has limited data on the physicochemical properties of pineapple peel for several ripening stages. It has high added value in many areas of study and approach to green technology development. For such industrial processes to be technically and economically feasible, it is important to have the analysis data of the physicochemical properties. Thus, physicochemical properties study of pineapple peel extract is very important in fruit waste extract technology. This study examined the physicochemical properties of the pineapple peel extract variety N36 for three different ripening stages: indexes 1, 2 and 3. Physicochemical properties such as total soluble solids (TSS), pH, titratable acidity (TA), absorbance and pulp content of pineapple peel extract were determined. It was found that the physicochemical properties: TSS, pH values, TA, absorbance and pulp content were significantly increased at the 5% level with the increase in ripening stages. These new data on ripening changes occurring in pineapple (Ananas comosus) peel variety N36 can contribute to further development in the agricultural sector. (C) 2012 Published by Elsevier B. V.
