The major phenolics of 'd' Anjou' pear (Pyrus communis L.)
tissues were chlorogenic acid and arbutin. Chlorogenic acid
inhibited mycelial growth and spore germination of Penicillium
expansum and mycelial growth of Mucor piriformis. Slight increases
in radial growth and spore germination of Botrytis cinerea occurred
on chlorogenic acid media. Chlorogenic...
Alcoholic off-flavor and accompanying volatile compounds produced by bananas (Cavendishii spp) held at 20°C and subjected to aerobic (air control treatment) or anaerobic conditions (nitrogen treatment) were compared by solid phase micro extraction (SPME), a newly developed method for volatile separation. In general, volatile production was suppressed under anaerobic conditions...
Blackberry varieties were evaluated with modified atmosphere packaging, using films Cryovac D-940 and D-955 in 0° and 5°C storage. Moisture loss was kept extremely
low (less than 3%) in packaged fruits, but mold infection was excessively high because of high humidity accumulated inside the container. Blackberries selectively harvested
into 3...
Free abscisic acid (ABA) in Yellow Globe Danvers onion tissues was
determined during maturation and storage. The amount of ABA in leaf
tissue reached a maximum (1.81 ng/gm dry weight) at 40% top fall. Neck
tissue ABA reached a maximum (0.33 ng/gm dry weight) at 60-70% top fall.
ABA of...
This thesis research is a series of five studies dealing
with various aspects of hazelnut quality:
1. Identification of kernel mold and its incidence among
hazelnut varieties.
2. Seasonal development and composition of kernels.
3. Hazelnut oil composition (fatty acids and
tocopherols) of seventeen varieties.
4. Hazelnut oil composition compared...
'Anjou' pears were sprayed with 2 concentrations of
CaCl₂ during fruit development and harvested at 70 N flesh
firmness. Pears were held at -1.1°, 5°, 10°, or 20°C for up to
100 days then ripened at 20°C for 11 days. Unexpectently,
fruits stored at 20°C lost firmness and chlorophyll after...
The effect of some factors that can affect quality characteristics of broccoli
florets in storage was evaluated. Quality characteristics of broccoli florets with
different rates of field nitrogen (N) application (0, 90, 180, and 270 Kg N/ha from
urea) were evaluated in modified atmosphere packaging (MAP) (B-900 Cryovac
film) storage...
