Impact of season and maturity stage on biochemical parameters of Averrhoa carambola fruits

The nutritional quality of fruits can be affected by changes in physiological indicators during fruit ripening, which is why it is important to identify the stage of maturity and the appropriate season for harvesting. Based on this observation, this study was carried out to evaluate the influence of the two different seasons and the stage of maturity on the nutritional parameters of Averrhoa Carambola. The results showed a significant effect (p<0.0001) of the two seasons and maturity stage on the biochemical parameters of A. carambola fruits. Ash contents and pH were significantly high in rainy seasons and at the ripe stage. Their values were respectively (6.80±0.59%) and (3.54±0.27). Moisture and titratable acidity concentrations decreased significantly during maturation while total sugars, reducing and non-reducing sugars, and total soluble solids increased significantly during maturation. vitamin C and phenolic compounds were more abundant in the dry season and at the green stage. The values were Vitamin C (15,869.64±0.03 mg/g), polyphenols (30.92±0.03 mg GAE/mg), flavonoids (30.59±0.28 mg EQ/g) and tannins (21-.02±0.01 mg GAE/g). This study suggests that there are differences in the biochemical parameters of starfruit between seasons depending on the maturity stage. The data provided useful information on the season and ideal stage of maturity for harvesting and their use in food products.
