This study examined the impact of chitosan hybrid coatings on the shelf life and quality of jackfruit bulbs. They compared bulbs treated with chitosan alone, chitosan-TiO2 hybrid coating, and chitosan-TiO2-ZnO-MgO hybrid coating. Results showed that the chitosan-TiO2-ZnO-MgO hybrid coating led to the longest shelf life with the least weight loss, improved antioxidant capacity, and higher levels of vitamin C, carotenoids, and phenolic compounds. The coating was also found to be non-toxic according to the Artemia salina test.
This study evaluated the effect of chitosan hybrid coatings on the shelf life and quality of jackfruit bulbs. The treatments include control bulbs, bulbs with the chitosan coating (CS bulbs), bulbs with the chitosan-TiO2 hybrid coating (CSTiO2 bulbs) and bulbs with the chitosan-TiO2-ZnO-MgO hybrid coating (CSTZM bulbs). Bulbs were stored at 4 degrees C. Shelf life of control, CS, CSTiO2 and CSTZM bulbs were 4, 10, 13 and 15 days, respectively. The CSTZM bulbs exhibited < 1% weight loss, a decrease in the pattern of respiration, the highest levels of vitamin C (28.27 mg/100 g), carotenoids (10868.91 mu g/100 g), phenolic compounds (31.31 mg/100 g) and antioxidant capacity (283.49-444.36 mmol/100 g). According to the Artemia salina test, all coatings were non-toxic. In conclusion, the chitosan-TiO2-ZnO-MgO hybrid coating was the best alternative to extend the shelf-life of fresh-cut jackfruit.
