In-shell, peeled and blanched peanut samples were characterized in relation to proximate composition and fatty acid profile. No difference was found in relation to its proximate composition. The three major fatty acids were palmitic acid, oleic acid, and linoleic acid. In order to investigate irradiation and storage effects, peanut samples were submitted to doses of 0.0, 5.0, 7.5 or 10.0 kGy, s...

The pH-dependence of acid-induced growth in excised segments of Avena sativa coleoptiles has been reinvestigated in the pH range 3 to 7. In contrast to previous reports (e.g. DL Rayle [1973] Planta 114: 63-73), only acidic buffers with a pH below 5.0 induce an extension response. A pH of 3.5 to 4.0 is required to mimic auxin-mediated growth. Very similar pH-response curves are obtained with bot...

Single muscle fibers from rabbit soleus and adductor magnus and from semitendinosus muscles were peeled to remove the sarcolemma and then stimulated to release Ca2+ by (a) caffeine application or (b) ionic depolarization accomplished via substitution of choline chloride for potassium propionate at constant [K+] X [Cl-] in the bathing solution. Each stimulus, ionic or caffeine, elicited an isome...

Chlorpropham (isopropyl 3-chlorocarbanilate) is a pesticide used to control sprouting of potatoes during long-term storage. The objective of the present study was to establish the total chlorpropham residue balance (residues in unwashed and washed whole tubers, peeled tubers, peels, boiled and pureed tubers, and washing and cooking waters) for two potato varieties after uniform application as a...

Garlic storage is important to provide product for fresh market and fresh peeled processing. Garlic bulbs (cv. California Late) and unpeeled cloves were stored in several experiments in air and CA (0.1, 0.5, 1% O2 in combination with 0, 5, 10, 15 and 20% CO2) at 0-1°C for up to 6 months. Quality changes, especially sprout growth, decay and discoloration, were reduced by CO2-containing atmospher...

As typical anchorage-dependent cells myocytes must balance contractility against adequate adhesion. Skeletal myotubes grown as isolated strips from myoblasts on micropatterned glass exhibited spontaneous peeling after one end of the myotube was mechanically detached. Such results indicate the development of a prestress in the cells. To assess this prestress and study the dynamic adhesion streng...

This work aimed at highlighting the role played by the skin in the light propagation through the apple flesh. A multispectral Visible-Near Infrared (Vis-NIR) steady-state imaging setup based on the use of four continuous laser sources (633, 763, 784, and 852 nm) and a charge–coupled–device (CCD) camera was developed to record light diffusion inside apple tissues. Backscattering images and light...
