Immature, vegetable-like fruits are produced by crops of great economic importance, including cucumbers, zucchini, eggplants and bell peppers, among others. Because of their high respiration rates, associated with high rates of dehydration and metabolism, and their susceptibility to chilling injury (CI), vegetable fruits are highly perishable commodities, requiring particular storage conditions...

The European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae), is a quarantine pest for several fresh commodities, including corn-on-the-cob, bell peppers, and green beans. Methyl bromide fumigation is the usual phytosanitary treatment, but the fumigant is under increasing regulation as a stratospheric ozone-depleting substance. Ionizing radiation is a relatively new commercial ...

shipped long distances and supply was dependent on local production areas. Demand for year-round, inexpensive produce has led to consolidation of production where temperatures are warm, sunshine is plentiful, and labor is cheap. In most cases, produce is now shipped long distances before being consumed. Tomatoes grown in Mexico are trucked 3,500 miles, bananas grown in Ecuador travel 6,000 mile...

Pectin methylesterase (PME) from green bell peppers (Capsicum annuum) was extracted and purified by affinity chromatography on a CNBr-Sepharose-PMEI column. A single protein peak with pectin methylesterase activity was observed. For the pepper PME, a biochemical characterization in terms of molar mass (MM), isoelectric points (pI), and kinetic parameters for activity and thermostability was per...

A range of gas conditions was generated by packing individual capsicums (green ‘Tasty’ bell peppers, Capsicum annuum L.) in packages with different areas of permeable low-density polyethylene film (0.0006–0.48 m) at four different temperatures (0, 12, 20 and 30°C). Steady-state O2 and CO2 partial pressures in the package were used to calculate rates of O2 uptake and CO2 production. The results ...

285 Premium wine quality can be achieved only through a favorable balance between fruit, fermentation, and processingderived aromas and flavors. The 3-alkyl-2-methoxypyrazines produce vegetative odors characteristic of green bell peppers and peas. The olfactory threshold at which these compounds are sensed is extraordinarily low: 1 to 10 ng/L in water. These compounds, 3-isobutyl-2-methoxypyraz...

"Padrón-type" peppers are a small variety of Capsicum annuum cultivated mainly in Galicia, Spain. To compare the effects of freezing and freeze-drying on the volatile components of Padrón-type peppers, preserved samples are analyzed by means of dynamic headspace sampling on an adsorbent followed by microwave desorption into a gas chromatograph equipped with a mass spectrometric detector. Sixty-...
