In rice (Oryza sativa), the presence of a dominant Badh2 allele encoding betaine aldehyde dehydrogenase (BADH2) inhibits the synthesis of 2-acetyl-1-pyrroline (2AP), a potent flavor component in rice fragrance. By contrast, its two recessive alleles, badh2-E2 and badh2-E7, induce 2AP formation. Badh2 was found to be transcribed in all tissues tested except for roots, and the transcript was dete...

Rice bread is a potential alternative to wheat bread for gluten-sensitive individuals. Incorporation of rice bran into bread made from white rice flour adds flavor but also phytic acid, which can reduce the bioavailability of minerals. Breads with varied amounts of defatted bran and yeast were prepared to determine their effects on the phytate and mineral contents of the bread. A completely ran...

Ferulago angulata subsp. carduchorum (Boiss. & Hausskn.) D.F. Chamb is a perennial species of the family Apiaceae and is locally used as a flavouring agent and for some medicinal properties. The essential oil of this plant if found to possess antibacterial and antifungal activities. The present study is aimed to determine constituents of essential oils from inflorescence of four F. angulata sub...

Linolenic acid is an important fatty acid, and volatiles generated by its oxidation are the major components of food flavor. In this study, volatile from linolenic during heating were detected analyzed using thermal desorption cryo-trapping system coupled with gas chromatography-mass spectrometry. A total 52 compounds identified, including aldehydes (18), ketones (12), alcohols (6), furans (4),...

Reduction of foodborne illnesses and deaths by improving the safety of poultry products is one of the priority areas in the United States, and developing and implementing effective food processing technologies can be very effective to accomplish that goal. Irradiation is an effective processing technology for eliminating pathogens in poultry meat. Addition of antimicrobial agents during process...

With the advent of the -omics era, classical technology platforms, such as hyphenated mass spectrometry, are currently undergoing a transformation toward high-throughput application. These novel platforms yield highly detailed metabolite profiles in large numbers of samples. Such profiles can be used as fingerprints for the accurate identification and classification of samples as well as for th...

Purple rice is a strain of glutaneous rice rich in anthocyanins and γ-oryzanol. Both types of compounds are involved in antioxidant and lipid metabolism of mammals. Three experimental diet types were used which consisted approximately by half either of purple rice, white rice or corn. Diets were fed to 3×10 pigs growing from about 30 to 100 kg. Meat samples were investigated either as raw or cu...
