Heat treatment and fruit ripening
Postharvest heat treatments lead to an alteration of gene expression and fruit ripening can sometimes be either delayed or disrupted. The extent of the alternation of fruit ripening is a function of the exposure temperature and duration and how quickly the commodity is cooled following the heat treatment. The most commonly measured components of fruit ripening affected by heat treatments includ...
متن کاملApple Fruit Pectic Substances.
1. The pectic substances of apple have been extracted and separated into a pure pectinic acid and a neutral arabinan-galactan complex by precipitation of the acidic component with ethanol and with cetylpyridinium chloride. 2. The composition of the fractions has been determined. The pectinic acid contained galacturonic acid, arabinose, galactose, rhamnose, xylose and several trace sugars. 3. Tr...
متن کاملA comparison of heat treatment and ascorbic acid on controlling enzymatic browning of fresh-cuts apple fruit
Enzymatic browning of apple fruits (Malus × domestica Borkh.) is the main factor responsible for quality deterioration in processed products such as juice, fresh-cut slices and chips.The fresh slices of apple were dipped in 1% ascorbic acid solution for one min and hot water with 50°C for two min. The results showed that both heat and ascorbic acid treatments could significantly reduce cut surf...
متن کاملHeat-induced protection against death of suspension- cultured apple fruit cells exposed to low temperature
Death of suspension-cultured apple fruit cells ( Malus domestica Borkh. cv. Braeburn), resulting from exposure to low temperature (1 ° C), was reduced by a prior 1 h/38 ° C treatment. Pre-heated chilled cells produced less ethylene, indicating lower chilling injury. Heat treatment resulted in increased transcripts for a low molecular weight (hsp17) and a 70 kDa heat shock protein (hsp), but exp...
متن کاملTranscriptional analysis of apple fruit proanthocyanidin biosynthesis
Proanthocyanidins (PAs) are products of the flavonoid pathway, which also leads to the production of anthocyanins and flavonols. Many flavonoids have antioxidant properties and may have beneficial effects for human health. PAs are found in the seeds and fruits of many plants. In apple fruit (Malus × domestica Borkh.), the flavonoid biosynthetic pathway is most active in the skin, with the flava...
