“…[29] Physicochemical Characterization Physicochemical properties of fruits, such as SS and acidity are related to their ripeness and may become a harvest or quality index. [30] A good balance among pH, sugars, and titratable acidity is necessary for optimal taste. It was suggested that a sugar:acid ratio between 10:1 and 18:1 is indicative of a good taste and acceptability of a fruit.…”

1) Comparative analysis of betalain content inStenocereus stellatus fruits and other cactus fruits using principal component analysis Running head: Principal component analysis of cactus fruits pigments Abstract Stenocereus stellatus fruits from Puebla, Mexico, with red, purple, yellow, and white pulp were characterized regarding their total betalain (TB) content, and physicochemical properties. The TB content was 856.07-2968 µg per gram of pulp dry weight (DW). Using principal component analysis, the levels of pigments in S. stellatus fruits were compared with 32 samples from other Downloaded by [New York University] at 14:58 31 May 2015A c c e p t e d M a n u s c r i p t 2 cactus fruits. As a result, 3 confidence intervals for TB content (µg g -1 ) were calculated: low (< 1208), medium (2935-3288) and high (4488-9248). Thus, the cactus fruits can be categorized as a poor, good, and excellent source of betalain pigments.

The aril around the seeds of Gac fruit is rich in fatty acids and carotenoids (lycopene and β‐carotene). Understanding how these qualities are affected by fruit maturity at harvest may identify indices for quality assessment. Some physical and chemical properties of Gac fruit were determined for fruit harvested between 8 and 16 weeks after pollination (WAP). Fruit respiration rates and ethylene production rates were assessed after harvest and up to 20 days in storage at 20°C. Fruit harvested at 14 WAP had the highest oil (0.27 ± 0.02 g/g DW), lycopene content (0.45 ± 0.09 mg/g FW), and β‐carotene content (0.33 ± 0.05 mg/g FW) which declined by 16 WAP. External skin color and aril TSS were indicative of oil and carotenoid contents in aril. Skin color, TSS and potentially firmness were good indices of fruit quality. Harvesting less mature fruit at 12 WAP would be practical as the fruit were firmer and more capable of transport; however, quality during postharvest ripening may be limited. Fruits continued to ripen after they were harvested and an ethylene peak in the least mature fruit may reflect a climacteric behavior but this needs further investigation.

“…It was found (Ruzainah, Rahman, Ridhwan, Che, & Nor Zaini Vasudevan, 2009) that it consists of 0.270 g of protein; 0.552 g/L glucose and 132.95 mg/L ascorbic acid of dragon fruit stem and found higher than the fruit flesh of the dragon fruit. The premature stem (Wanitchang, Terdwongworakul, Wanitchang, & Noypitak, 2010) had higher values than the mature stem of the dragon fruit which may be helpful in preventing the risk factors of certain diseases. The organic components in the stems of pitaya were identified by GC-MS and the contents of their mineral elements were determined by ICP-MS.…”
