Value We used the following juices, listed in roughly decreasing order of preference (associated colors in parenthesis): high-sugar lemon Kool-Aid (dark yellow), grape juice (bright green), fruit punch (magenta), apple juice (diluted to 1/2 with water, dark green), cranberry juice (diluted to 1/3 or 1/4 with water, pink), water (white), milk (red), peppermint tea (bright blue), tea (light brown...

Juices from 2 cultivars of muscadine grapes (Vitis rotundifolia Michx.), 'Noble' (dark-skinned) and 'Carlos' (bronze-skinned), were mixed with juices of 'Concord' and 'Niagara' grapes, cranberry or apple. 'Noble' juice, combined with 'Concord' juice, resulted in the highest quality among the dark mixtures prepared. Also, the mixtures retained most color and flavor during a 12 month storage peri...

Organic foods are promoted as environmentally friendly and its consumption has become increasingly popular. Nevertheless, organic farming practices could produce commodities more susceptible to fungal attack and as a result, food with higher levels of mycotoxins. Patulin is a mycotoxin mainly present in apples and apple-based products. In this paper, we report our recent results and an update o...

The present authors investigated whether wheezing is less common in children who consume more apples and other fruits. A population-based survey of 2,640 primary school children aged 5-10 yrs was carried out in Greenwich (South London, UK). Information about asthma symptoms and fruit consumption was obtained by means of a questionnaire. After controlling for potential confounding variables, eat...

This section covers information, where available, on microbial kinetics and relevant safety considerations when ultraviolet (UV) radiation is used for the purposes of food preservation. The section pays particular attention to the growing interest in using UV light to treat fruit juices, especially apple juice and cider. It does not include pulsed UV, which is being actively investigated by Dr....

HERCEGOVÁ, A., MŐDER, M.: Determination of some selected pesticide residues in apple juice by solid-phase microextraction coupled to gas chromatography – mass spectrometry. Acta univ. agric. et silvic. Mendel. Brun., 2011, LIX, No. 1, pp. 121–128 The performance of solid phase microextraction (SPME) for enrichment of pesticides from apple juice was investigated. Samples were diluted with water,...

Apples are rich in components that are important for human health, such as polyphenols, organic acids and microelements, but their chemical composition varies with different apple cultivars. We aimed to find out if there is any superiority in traditionally grown apple cultivars in terms of their fruits’ bioactive components content. Juice from two traditionally grown apple cultivars, ‘Mutsu’ an...

Commercial apple juice inoculated with Escherichia coli was treated with UV-C, heat (55°C) and dimethyl dicarbonate - DMDC (25, 50, and 75 mg/L)-, applied separately and in combination, in order to investigate the possibility of synergistic lethal effects. The inactivation levels resulting from each treatment applied individually for a maximum treatment time of 3.58 min were limited, reaching 1...
