Non-destructive firmness sensors have recently become available for packers and fruit handlers although they demand more information on their performance and reliability. A commercial sensor, aimed both for in-line or bench-top usage, based on low mass impact has been tested on kiwifruit. Correlation between the firmness index given by the device and Magness-Taylor force was low (R 2 = 0.594 an...

The objective of this study is to clarify the difference in susceptibility to protease digestion by kiwifruit juice between collagen domains under different conditions. In addition, the effect of pre-treatment with kiwifruit juice on collagen in meat during cooking processes was examined. Kiwifruit juice can degrade denatured collagen, but it can not cleave the triple helical domain of collagen...

Gray mold, caused by the fungus Botrytis cinerea, is the most significant postharvest disease of kiwifruit. In the present study, iTRAQ with LC-ESI-MS/MS was used to identify the kiwifruit proteins associated with the response to B. cinerea. A total of 2,487 proteins in kiwifruit were identified. Among them, 292 represented differentially accumulated proteins (DAPs), with 196 DAPs having increa...

Consumption of kiwifruit is reported to relieve symptoms of functional gastrointestinal (GI) disorder. The effect may be related to the proteases in kiwifruit. This in vitro study aimed to measure protein hydrolysis due to kiwifruit protease under gastric and duodenal conditions. A sequence of experiments incubated meat protein, with and without kiwifruit, with varying concentrations of pepsin ...

In this work, we tried to evaluate mass transfer during a combined infrared-vacuum drying of kiwifruits. Infrared radiation power (200-300 W) and system pressure (5-15 kPa), as drying parameters, are evaluated on drying characteristics of kiwifruits. Both the infrared lamp power and vacuum pressure affected the drying time of kiwifruit slices. Nine different mathematical models were evaluated f...

The identification of B-cell epitopes is an important step to study the antigen- antibody interactions for diagnosis and therapy. The present study aimed to identify B- cell epitopes of osmotin using bioinformatic tools and further modify these regions to study the allergenic property. B-cell epitopes were predicted based on amino acid physicochemical properties. Three single point mutations M1...

We investigated the effects of different concentrations (0, 1, 2 and 4 mM) of putrescine on chilling injury, fruit quality, ethylene production rate, fatty acid composition and the antioxidant system of cold-stored kiwifruit (Actinidia chinensis Planch. var. chinensis 'Hongyang'). We achieved a significant decrease in ethylene production, maintained fruit quality and alleviated chilling injury ...

The kiwifruit (Actinidia chinensis) is an economically and nutritionally important fruit crop with remarkably high vitamin C content. Here we report the draft genome sequence of a heterozygous kiwifruit, assembled from ~140-fold next-generation sequencing data. The assembled genome has a total length of 616.1 Mb and contains 39,040 genes. Comparative genomic analysis reveals that the kiwifruit ...

Abstract In vitro-derived plants with elevated ploidy levels can display distinguishing features from the they are derived from, especially owing to their indirect regeneration. Genome size affects cell and, thus, plant morphological characteristics. Therefore, stomata traits may be used as a diagnostic feature allowing identification of ploidy. Actinidia chinensis var. deliciosa A. Chev. (A. C...
