Comparative Study on fruit Quality of Mature-Green Eating Mangoes

บทคัดย่อ

The comparative study on fruit quality of eight mature-green eating mago cultivars namely ‘Malila’ ‘Tongdum’ ‘lin Ngu Hou’ ‘Kiew Sawoey’ ‘Read’ ‘Pimsen Mun’ ‘Nong Saeng’ and ‘Mun Haew’ was investigated in reation to their physical and chemical characters. The results showed that Malila had the highest fruit weight and largest fruit weight and largest fruit volume. The specific gravity of the fruit was found significantly different among these cultivars with Mun Heaw, Lin Ngu Hoa and Tongdum had the specific gravity greater than 1.0 and high vitamin C content (28.75-30.74 mg/100 g fresh weight) while Malila, Kiew Sawoey, Raed and Nong Saeng had the specific gravity lower than 1.0 and low vitamin C content (15.42-19.55 mg/100 g fresh weight). Mun Haew, Nong Saeng, Lin Ngu Hou and kiew Sawoey were the cultivars having high ratio of total soluble solids/titratable acidity (15.37-25.68) but Tongdum, Pimsen Mun and Read cultivars had low ratio of soluble solids/titratable acidity (7.42-7.66). These mangoes had total nonstructural carbohydrates ranged from 510.54 to 8.6.54 mg D-glucose/g dry weight. Cultivars with low ratio of total soluble solids/titratable acidity tended to have low total nonstructural carbohydrates.
