This study aimed at understanding softening in Jonagold apple (Malus×domestica Borkh.) fruits, by investigating pectin modifications and the evolution of pectin-modifying enzymes during postharvest storage and ripening. Jonagold apples were harvested at commercial maturity and stored at different temperatures and controlled atmosphere conditions for 6 months, followed by exposure to ambient she...

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...

The discharge of palm oil mill effluent (POME) without effective treatment is highly toxic to the environment and receiving waters due its high chemical oxygen demand , biochemical increased levels suspended solids. ponding system regarded as a conventional method for POME but requires long retention time extensive areas. Other processes, such physicochemical treatment, have also been applied t...

The beneficial effects of Juniperus communis L. extracts have been known for a long time. Therefore scientific knowledge the chemical profile leading to this bioactivity is required. aim paper highlight influence geographical origin and harvest time on compositional elements hydroalcoholic J. pseudo-fruits, but also their antibacterial properties. samples were collected from three mountainous a...

Nature of Work: Japanese beetles (JB), Popillia japonica Newman, are destructive, highly polyphagus herbivores that show a general preference for plants in the Rosaceae family. Although Malus taxa are often found to be susceptible to JB, there are substantial differences in resistance among Malus species and cultivars (1,2). In a prior study, total phenolic levels in Malus were not correlated w...

background & aim: the use of herbs in traditional medicine to treatment of diseases and other purposes in the food industry and cosmetics has since long been considered.  considering that heracleum lasiopetalum, thymus carmanicus and myrtus communis have many health benefits therefore this research were performed to investigate the chemical composition of essential oils from these plants. e...

Malic enzyme was isolated and purified from mature apple fruits (Malus sylvestris, Miller) by utilizing procedures probably applicable to other soluble enzymes in this and similar tissues.The physical properties of apple fruit malic enzyme are similar to those reported for malic enzyme from other plant and animal sources. It is specific for l-malate, TPN and requires a divalent cation for activ...
