Nagaland University researchers have developed a novel method for converting pineapple processing waste into high-quality vinegar, addressing both environmental and economic challenges associated with fruit waste. This research, published in the European Journal of Nutrition and Food Safety, highlights the significant amounts of waste generated during pineapple processing, including peels, pomace, cores, and crowns, much of which is typically discarded. The environmental impact is exacerbated by poor handling and storage practices, leading to further waste.
The research team, including Sentinaro Walling, Prof. Akali Sema, Prof. C.S. Maiti, Dr. Animesh Sarkar, Prof. S.P. Kanaujia, and Ms. Alemla Imchen from the Department of Horticulture, emphasizes the potential of transforming these discarded materials into commercially viable products. Prof. Jagadish K Patnaik, Vice Chancellor of Nagaland University, hailed the findings as a significant breakthrough, reflecting the university’s commitment to sustainable practices, enhancement of rural livelihoods, and innovative agricultural solutions.
The investigation revealed that utilizing pineapple peels in the vinegar production process led to superior acidity, color, and flavor compared to other parts of the fruit. Sensory evaluations indicated that the peel-based vinegar was preferred for its taste and aroma, validating its potential as a high-quality, marketable product.
This research advocates for sustainable pineapple production methods and adds value to agricultural by-products, thus providing new opportunities for entrepreneurship and community-based enterprises. Nagaland, recognized for its exceptional pineapple varieties such as ‘KEW’ and ‘Queen,’ has become a significant player in the pineapple industry in India. Supportive government initiatives like the Mission for Integrated Development of Horticulture (MIDH) promote commercial pineapple cultivation, particularly in districts like Chumoukedima, Niuland, Dimapur, Kiphire, and Mokokchung, reinforcing the region’s agricultural viability and economic prospects.
