Aroma chemistry of African Oryza glaberrima and Oryza sativa rice and their interspecific hybrids.

Background: To increase rice production in Africa, considerable research has focused on creating interspecific hybrids between African (Oryza glaberrima Steud.) and Asian (O. sativa L.

Production of trans-free margarine with stearidonic acid soybean and high-stearate soybean oils-based structured lipid.

Unlabelled: Omega-3 fatty acids (n-3 FAs) have been positively associated with prevention and treatment of chronic diseases. Intake of high amounts of trans fatty acids (TFAs) is correlated with increased risk of coronary heart disease, inflammation, and cancer. Structured lipid (SL) was synthesized using stearidonic acid (SDA) soybean oil and high-stearate soybean oil catalyzed by Lipozyme(®) TLIM lipase.

Update on the healthful lipid constituents of commercially important tree nuts.

Uncharacteristic of most whole foods, the major component of tree nuts is lipid; surprisingly, information on the lipid constituents in tree nuts has been sporadic and, for the most part, not well reported. Most published papers focus on only one nut type, or those that report a cultivar lack a quality control program, thus making data comparisons difficult. The present study was designed to quantify the healthful lipid constituents of 10 different types of commercially important tree nuts (i.

Comparison of odor-active compounds from six distinctly different rice flavor types.

Using a dynamic headspace system with Tenax trap, GC-MS, GC-olfactometry (GC-O), and multivariate analysis, the aroma chemistry of six distinctly different rice flavor types (basmati, jasmine, two Korean japonica cultivars, black rice, and a nonaromatic rice) was analyzed. A total of 36 odorants from cooked samples were characterized by trained assessors. Twenty-five odorants had an intermediate or greater intensity (odor intensity >or= 3) and were considered to be major odor-active compounds.

Does the alternative pathway ameliorate chilling injury in sensitive plant tissues?

Free radical processes have been observed in senescence and several membrane-associated disorders of plants including chilling, freezing, and desiccation injuries. The mitochondria of plant tissues exposed to low temperatures, and other abiotic and biotic stresses, produce superoxide and/or hydrogen peroxide when electron transport through the cytochrome pathway is impaired due to the energy state of the cell or to stress-induced physical changes in the membrane components. The superoxide and/or hydrogen peroxide produced can diffuse throughout the cell causing peroxidation of membrane lipids which results in membrane disruption, increased permeability and metabolic disturbances, and eventually the visible symptoms of chilling injury.
