The study was conducted to standardize the protocol for preparation of wild apricot fruit bar. Wild apricot fruits were harvested at optimum maturity from Distt Tehri Garhwal, Uttarakhand and after thorough sorting and proper washing, used for hot extraction of pulp through a pulper. Pulp was preserved in 500 ppm SO2 (using potassium metabisulphite). For preparation of fruit bars, additives like sugar and pectin were added to the pulp in different proportions and the mixture dried in mechanical dehydrator. Dried fruit bar sheets were cut into rectangular shapes (2.5 × 4.0 cm(2)) using a stainless steel knife and wrapped in polythene paper. Best recipe was selected on the basis of sensory evaluation. For storage, wild apricot fruit bar was packed in aluminium laminated pouches and polyethylene pouches, kept for 6 months and analyzed periodically for changes in quality. Results of the sensory evaluation indicate that a very good quality fruit bar can be prepared by using wild apricot pulp +60% sugar +0.30% pectin and drying the mixture in a mechanical dehydrator at 55 ± 2 °C for 6 h. During 6 months of storage, there was about 3% moisture gain, 6.00 and 9.35% loss in total sugars and vitamin C respectively, along with slight losses in titratable acidity and sensory quality. The changes in chemical and sensory quality attributes were minimum in wild apricot fruit bar, packed in aluminium laminated pouches as compared to those packed in polyethylene pouches, and the product stored under vacuum than that under normal atmosphere. Further, the products were stable up to 6 months during storage under ambient condition.
本研究旨在规范制备野生巴旦杏果脯的方案。从北阿坎德邦特赫里-加瓦尔地区收获成熟度最佳的野生巴旦杏果实,经过彻底分拣和适当清洗后,通过打浆机进行热提取果肉。果肉用 500ppm 的 SO2(使用偏重亚硫酸钾)保存。为了制备果脯,向果肉中添加不同比例的糖和果胶等添加剂,并在机械脱水器中干燥混合物。将干燥的果脯片切成 2.5×4.0cm²的长方形(2.5×4.0cm²),使用不锈钢刀,然后用聚乙烯纸包装。根据感官评价选择最佳配方。为了储存,将野生巴旦杏果脯用铝塑复合袋和聚乙烯袋包装,储存 6 个月,并定期分析质量变化。感官评价结果表明,使用野生巴旦杏果肉+60%糖+0.30%果胶,并在 55±2°C 的机械脱水器中干燥混合物 6 小时,可以制备出质量非常好的果脯。在 6 个月的储存期内,水分增加约 3%,总糖和维生素 C 分别损失 6.00%和 9.35%,滴定酸度和感官质量略有下降。与包装在聚乙烯袋中的产品相比,包装在铝塑复合袋中的产品以及在真空下储存的产品在化学和感官质量属性方面的变化最小,在环境条件下储存时,产品在 6 个月内保持稳定。
