Pectins analysed by AFM are visualized as individual chains, branched or unbranched, and aggregates. To investigate the nature of these structures, sodium carbonate soluble pectins from strawberry fruits were digested with endo-Polygalacturonase M2 from Aspergillus aculeatus and visualized by AFM. A gradual decrease in the length of chains was observed as result of the treatment, reaching a min...

in 2007 and 2008, the influence of pollen source on the shell and kernel traits of resulting seeds and on fruit set was examined to evaluate the potential for xenia or metaxenia in persian walnut. pistillate flowers of ‘jamal’, ‘chandler’, ‘hartley’ and ‘pedro’ were crossed with the pollen of ‘serr’, ‘z60’ and ‘damavand’. the pistillate flowers on each female parent were covered about one week ...

Participation in global trade means that China’s vegetables and fruits industry faces international food safety standards and increased scrutiny worldwide. The objectives of this paper were to investigate how existing food safety standards and regulations in the importing countries impact the export of vegetables and fruits from China. This paper discussed the current and historical situations ...

AIM To investigate the relationship between the colors of vegetables and fruits and the risk of colorectal cancer in Korea. METHODS A case-control study was conducted with 923 colorectal cancer patients and 1846 controls recruited from the National Cancer Center in Korea. We classified vegetables and fruits into four groups according to the color of their edible parts (e.g., green, orange/yel...

The rabbit's gastrointestinal physiology is a complex system that centers around the separation of digestible and indigestible components of the diet in the proximal colon. The clinical importance of this system is the need for a consistent diet high in long particle length (> 0.5 mm) indigestible fiber to maintain the motility of the cecum and colon. Most of the common gastrointestinal problem...

A high-performance liquid chromatographic method was developed for the analysis of capsaicinoid compounds, the pungent principles of capsicum fruits. A sequential simplex method was applied to optimize the chromatographic response function used to assess the quality of separation by varying the chromatographic parameters. The separation was achieved in 11 min using a C-8 column of 15-cm length ...

Introduction Abstract: We investigated the extent of multiple paternity within and between fruits of the common milkweed, Asclepias syriaca, at one site. Using isozyme polymorphisms at four loci and the maximum likelihood methods of Williams and Evarts (1989), we found no statistical evidence for multiple paternity within fruits. When pairs of fruits obtained from individual ramets were analyze...

Gleditsiae Fructus Abnormalis and Gleditsiae Sinensis Fructus are obtained from different developmental stages of fruits from Gleditsia sinensis Lam. (Leguminosae). The possible interchangeable usage of the two fruits, however, has long been very controversial. Here, high performance liquid chromatography coupled with diode array detection was developed to explore their chemical fingerprinting ...

Ionizing radiation is useful for the conservation and disinfestation of fresh and dried fruits. The treatment of fruits with gamma-rays or beams of accelerated electrons has been carefully tested and was recommended by FAO/WHO Codex Alimentarius Commission for the common use as an effective and safe preservation method [1]. It was found earlier that the ionizing radiation produces stable EPR si...

Consumption of diets high in fruits and vegetables is associated with reduced risk of chronic diseases, and self-efficacy and the food environment influence consumption of fruits and vegetables. We analyzed data from 3,021 non-Hispanic white (n = 2,187) and non-Hispanic black (n = 834) US adults who responded to National Cancer Institute's 2007 Food Attitudes and Behaviors Survey to assesss sel...
