Nutritional composition and quality evaluation of products prepared from wild peach (Prunus persica)

The study was conducted to evaluate nutritive composition, functional constituents and to develop food products, i.e., jam and chutney in combination with cultivated peach pulp in different proportions. The fruit contain good amounts of phosphorous content (39.16 mg/100 g). The prepared products (jam and chutney) were studied for quality evaluation during storage interval of 9 months. The results for jam in terms of different blending proportions shows that the TSS (oB), pH, ascorbic acid (mg/100 g), reducing, total and non-reducing sugars (%) increased with the addition of cultivated peach pulp with mean values ranged from 68.20oB-69.57oB, 2.95-3.24, 1.88-9.22, 21.79-24.70, 56.98-63.42 and 33.43-36.78, respectively while acidity (%) decreased from 1.28-1.05. Similar trend was observed for wild peach based chutney. Storage had significant effect on the mean values for jam and chutney. The TSS (oB), acidity, reducing and non reducing sugars increased from 68.51-69.04, 0.94-1.17, 23.26-26.21 and 39.62-30.89 while pH, ascorbic acid (mg/ 100 g), and total sugars (%) decreased from 3.16-3.04, 6.04-4.43 and 63.31-56.96, respectively for jam during storage of 9 months. Similar observations were reported for chutney. The prepared products, viz., jam and chutney were subjected for sensory evaluation to a panel of members at different storage intervals i.e. (fresh, 3, 6 and 9 months of storage period) and the products were found as acceptable in terms of colour, taste, consistency/texture even up to storage interval of 9 months at ambient conditions.
