This study reports an unusual case of repeated anaphylactic episodes to orange and apple without clinical evidence of primary sensitization to peach LTP. In vitro and in vivo tests revealed heat stability of the implicated allergens and also provided new evidence of differences in allergenicity among apple varieties and strong cross reactivity of citrus fruits. "Prick-to-prick" method with fres...

6 7 8 9 Abstract 10 Cyanogenic glycosides are natural plant toxicants. Action by endogenous plant enzymes 11 can release hydrogen cyanide causing potential toxicity issues for animals including 12 humans. We have quantified amygdalin in seeds from different apple varieties, determined 13 the effects of processing on the amygdalin content of apple juice and quantified amygdalin 14 in commerciall...

This work aimed at highlighting the role played by the skin in the light propagation through the apple flesh. A multispectral Visible-Near Infrared (Vis-NIR) steady-state imaging setup based on the use of four continuous laser sources (633, 763, 784, and 852 nm) and a charge–coupled–device (CCD) camera was developed to record light diffusion inside apple tissues. Backscattering images and light...

Apples are a rich source of polyphenols and fiber. A major proportion of apple polyphenols escape absorption in the small intestine and together with non-digestible polysaccharides reach the colon, where they can serve as substrates for bacterial fermentation. Animal studies suggest a synergistic interaction between apple polyphenols and the soluble fiber pectin; however, the effects of whole a...

The Red Delicious has for many years represented the ideal apple and has been a symbol of consistent crispness and delicious flavor. However, changes in the way Red Delicious varieties are bred, distributed, and sold threaten to displace the Red Delicious apple from its central role in the industry. One important component in this shift is the trend in the last decade of breeding Red Delicious ...

A chemometric study was carried out in order to typify cider apples according to their degree of ripening. Several chemical variables (sugars, organic acids, amino acids, polyphenols, and pectins) were analyzed using HPLC and FIA methods. Univariate data treatment was not sufficient to allow the apple varieties to be differentiated according to their stage of ripening. Two linear combinations o...

Hard cider is an important and growing part of the U.S. beverage market. Previous research suggests there opportunity for growers interested in selling locally grown cider-specific apple ( Malus domestica ) varieties. However, face production, distribution, marketing challenges. This article fills a gap literature using survey data from four states. We find that are expanding production to supp...

Metabolome analyses by NMR spectroscopy can be used in quality control by generating unique fingerprints of different species. Hundreds of components and their variation between different samples can be analyzed in a few minutes/hours with high accuracy and low cost of sample preparation. Here, apple peel and pulp extracts of a variety of apple cultivars were studied to assess their suitability...
