Enhancing the Palatability of Fibrous and Overmatured Vegetables Using Papaya as a Tenderizer

The present study explored the potential of raw matured papaya (Carica papaya) as a natural tenderizer to enhance the palatability of over-matured vegetables, which are often discarded due to fibrous texture and low consumer acceptability. Over-matured okra (Abelmoschus esculentus), banana pseudostem (Musa spp.), French bean (Phaseolus vulgaris), ridge gourd (Luffa acutangula), and amaranthus (Amaranthus spp.) were prepared with and without raw matured papaya, followed by organoleptic evaluation for appearance, texture, flavor, taste, and overall acceptability. Nutrient profiling, conducted at Tamil Nadu Agricultural University, Coimbatore using AOAC standard techniques, revealed that papaya addition significantly improved tenderness, juiciness, and sensory quality across all vegetables. These effects are attributed to papain, a proteolytic enzyme that hydrolyzes complex proteins and partially degrades fibrous tissues, thereby reducing chewiness caused by lignification. The nutritional analysis indicated slight reductions in crude fiber, marginal increases in moisture retention, and stable crude protein levels, suggesting potential improvement in protein digestibility. Sensory ranking placed okra highest in overall acceptability, followed by banana pseudostem, french bean, ridge gourd, and amaranthus. These findings highlight the efficacy of raw matured papaya as a cost-effective, eco-friendly tenderizing agent, offering a sustainable approach to reduce food waste, improve utilization of over-matured produce, and enhance dietary quality.
