Response surface optimization of the effect natural essential oils from clove, cumin and fennel in golden delicious apple fruit peroxidase inactivation

this study was carried out to examine the effects of kaolin spray for reducing the adverse effects of high radiation and temperature, especially on fruit sunburn in apple. treatments were four concentration of kaolin (0, 2, 4, and 6%) and two important and commercial apple cultivars in fars province; ‘golden delicious’ and ‘starking delicious’. trees physiological parameters, fruit sunburn and ...

Epiphytic micro-organisms isolated from fruits and leaves surfaces of apples from different orchards were screened for antagonistic activity against Penicillium expansum. From all micro-organisms tested the new strain CPA-5 of Pseudomonas syringae, isolated from organic orchard, was selected. This strain was very effective against Botrytis cinerea, P. expansum and Rhizopus stolonifer at various...

Currently, destructive methods are often used to measure the quality parameters of agricultural products. These complex, time consuming and costly. Recently, studying find a solution disadvantages has become major challenge for researchers. Non-destructive can be useful rapid detection In this study, hyperspectral imaging was evaluate non-destructive Red Delicious (Red Delicious) Golden (Golden...

The initial analysis of a quality classification system for ‘Jonagold’ and ‘Golden Delicious’ apples is shown. Color, texture and wavelet features are extracted from the apple images. Principal components analysis was applied on the extracted features and some preliminary performance tests were done with single and multi layer perceptrons. Keywordscomputer vision; image processing; defect segme...

Aging cylinders excised from ;Golden Delicious' apple (Pyrus malus L.) pulp, like the intact fruit, exhibit some characteristic phenomena such as rise in respiration (climacteric), ethylene synthesis, enzymic changes, and increase in ribosomes and mRNA. Aging of cylinders of pulp tissues may offer a useful physiological tool for the study of maturation and senescence.

In this article, biochemical analyzes have shown that the highest amount of dry soluble substances (16.9%) and ascorbic acid (8.6 mg / 100 g raw substance) apple fruits Golden Delicious variety had during crown formation according to a sparse tiered type. Laboratory autumn Delicious, winter Fuji showed fructose accounts for largest share total sugars, is, its content in varieties reaches 82.4–8...

Four of five apple cultivars (Golden Delicious, Red Delicious, McIntosh, Macoun, and Melrose) inoculated with Escherichia coli O157:H7 promoted growth of the bacterium in bruised tissue independent of the date of harvest (i.e., degree of apple ripening) or the source of the apple (i.e., tree-picked or dropped fruit). Apple harvest for this study began 4 September 1998 and ended 9 October, with ...
