Corinthian raisins (Vitis vinifera L., var. Apyrena) antioxidant and sugar content as affected by the drying process: a 3‐year study.

BACKGROUND: Corinthian raisins or Corinthian currants are dried grape products that account for approximately 3% of dried vine fruit production worldwide. Greece is the major Corinthian raisin producer. In this study Corinthian raisins were produced by applying two traditional drying methods, i.e. sun and shade drying. The drying process effect on the raisin phytochemical and […]

Microwave Application for Controlling Oryzaephilus surinamensis Insects Infesting Dried Figs and Evaluation of Product Color Changes Using an Image Processing Technique.

In this study, microwave heating was employed for controlling Oryzaephilus surinamensis adult beetles infesting stored Iranian dried figs. The dried fig samples were artificially infested with O. surinamensis and then heated in a microwave oven (2,450 MHz) at power outputs of 450, 720, and 900 W for 20, 30, 40, and 50 s. Changes in the color of the […]

Information integration of force sensing and machine vision for in-shell shrivelled walnut detection based on the golden-section search optimal discrimination threshold.

BACKGROUND: Shrivelled defect has a serious effect on walnut quality and is a common internal defect of in-shell walnuts. However, only depend on single detection technique such as machine vision to detect in-shell shrivelled walnuts is challenging. Meanwhile, the threshold has a great impact on the accuracy of the discrimination analysis. So the golden-section was […]

Determination of Sulfur in Grape and Apricot Samples Using High-resolution Continuum Source Electrothermal Molecular Absorption Spectrometry.

The determination of sulfur in apricot and grape samples was performed by using high-resolution continuum source electrothermal molecular absorption spectrometry based on vaporization of the carbon monosulfide (CS) molecule. CS forms in the gas phase without the addition of any molecule-forming element, since graphite cuvette contains plenty of carbon as well as food samples. A […]

Extending Storage Potential of De‐hulled Fresh Pistachios in Passive‐Modified Atmosphere.

BACKGROUND: The effects of passive-modified atmosphere packaging (passive-MAP) on the postharvest quality of de-hulled fresh pistachios (Pistacia vera L. cv. Kerman) stored at cold temperature (0 ± 0.5 °C) and 90 ± 1% R.H. was investigated with fruits under ambient air condition as the control treatment. The fruit quality parameters measured included kernel firmness, color […]

Microwave Use in the Control of Ephestia kuehniella (Lepidoptera: Pyralidae) in Dried Fig and Raisin and Effects on Fruit Sensory Characteristics.

Microwave heating is an environmentally friendly method for killing pest insects and here its efficacy in the control of a pest species of dried fig and raisin was assessed. Dried fig and raisin samples were infested with Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) larvae and heated in a microwave oven at power outputs of 450, 720, and 900 W for […]

RNA-Seq Reveals Flavonoid Biosynthesis-related Genes in Pecan (Carya illinoinensis) Kernels.

Pecan (Carya illinoinensis) is an important nut tree in the world. The high concentration of flavonoid in its kernels makes it an excellent healthy food. However, the molecular basis of flavonoid biosynthesis in pecan remains unclear, which hinders quality breeding in this plant. Therefore, in order to obtain crucial genes involved in flavonoid biosynthesis, the changes […]

Effects of Pecan Nut (Carya illinoiensis) and Roselle Flower (Hibiscus sabdariffa) as Antioxidant and Antimicrobial Agents for Sardines (Sardina pilchardus).

The effects of pecan nut (Carya illinoinensis) and roselle flower (Hibiscus sabdariffa) as antioxidant and antimicrobial agents on shelf life extension of sardines (Sardina pilchardus) were evaluated over a period of 5 days at 7 ± 1 °C. Treatments consisted of the addition of 5% and 10% w/w pecan nut, 5% w/w roselle flower and a combination of 5% of […]
