Effects of Maturity and Storage on Physical and Biochemical Changes in Peach and Apricot Fruits

Minimally Processed Refrigerated Fruits & Vegetables

“…As fruits and vegetables mature and are stored, ascorbic acid levels generally decrease (Augustin et al 1978;Matthews, Crill, and Locasio-1974;Nagy 1980). However, Kader, Heintz, and Chordas (1982) and Salunkhe, Deshpande, and Do (1968) found that fully Nutritional Quality of Fruits and Vegetables 315 ripe peaches had higher ascorbic acid levels than immature peaches. Mature bell peppers also contained higher ascorbic acid levels than those harvested green (immature) (Matthews, Locasio, and Ozaki 1975).…”

“…Mature bell peppers also contained higher ascorbic acid levels than those harvested green (immature) (Matthews, Locasio, and Ozaki 1975). Vitamin A generally increases with maturity (Kader, Heintz, and Chordas 1982;Matthews, Crill, and Locasio-1974;Salunkhe, Deshpande, and Do 1968). On the other hand, investigators disagree about the levels of ascorbic acid and vitamin A in tomatoes ripened on and off the vine (Betancourt, Stevens, and Kader 1977;Matthews, Crill, and Locasio-1974;Pantos and Markakis 1973).…”

Nutritional Consequences of Minimal Processing of Fruits and Vegetables

“…Peaches have higher vitamin C content when fully ripe or even overripe, than when immature (Salunkhe et al 1968;Kader et al 1982). Carotenoids follow a similar pattern, but the difference between immature (underripe) and fully ripe fruits is greater that with ascorbic acid.…”

“…Carotenoids follow a similar pattern, but the difference between immature (underripe) and fully ripe fruits is greater that with ascorbic acid. Unripe peaches held at room temperature synthesize carotenoids as they ripen, but this does not seem to occur with vitamin C (Salunkhe et al 1968). As bell peppers mature, both carotenoid and ascorbic acid content increase (Matthew et al 1975).…”

Average Daily Gain in Physico-Chemical Characteristics and Yield Efficiency of Some Apricot Cultivars Grown in Himalayan Temperate Region

“…Both yield efficiency flesh thickness of all the cultivars showed significantly (P < 0.05) high correlation with the leaf size (r 2 = 0.61 and 0.98, respectively) 6097 hectares (Anonymous, 2016). The apricot fruit has double sigmoidal growth pattern, having a retarded growth period at the time of pit hardening (Salunkhe et al, 1968). The yield of apricot is highly variable from year to year and poor yields are of frequent occurrence.…”
