Aflatoxigenic aspergilli inflict major economic damage to the tree nut industry of California, with the highest negative impact to almonds. Aspergilli and fungi in general are known to emit volatiles in varying quantity and composition dependent upon their growth media. The goal of the study was to determine the volatile emission of whole and blanched almonds that had been picked out and labele...

Ephedra intermedia is a dioecious plant of the Ephedraceae family whose male and female plants are quite similar in shape, but their biochemical differences are not known. The subject was the TLC and GC-MS study of fatty acids, phenols, essential oils, and alkaloids in male and female shoots of E. intermedia. Male and female shoots were collected from Markazi province in Iran, in spring. Alcoho...

Aims: This work is aimed at investigating physicochemical parameters and compositions of fatty acid, phospholipid sterol desert date (Balanites aegyptiaca) kernel pulp.
 Study Design: Balanites aegyptiaca fruit one the oldest feed-stocks in Africa which little or no attention has been given to it. The plant plays a diverse cultural traditional role different societies. Therefore, it very i...

The aroma-active compounds in Jinhua ham processed and stored for 9, 12, 15 and 18 months were extracted by dynamic headspace sampling (DHS) and solvent-assisted flavor evaporation (SAFE) and analyzed by gas chromatography-olfactometry-mass spectrometry (GC-O-MS). In GC-O-MS, volatile compounds were identified based on their mass spectrum, linear retention index (LRI), odor properties, or refer...

OBJECTIVE To produce anti-19-Nortestosterone (NT) monoclonal antibodies and identify their immunological characteristics. METHODS Hybridomas were prepared by fusing NS0 mouse myeloma cells with splenocytes isolated from immunized BALB/c mice. Noncompetitive and competitive indirect ELISA were employed to screen positive cell clones. A caprylic acid ammonium sulphate (CAAP) method was used to ...

BACKGROUND Omega hydroxy fatty acids (ω-OHFAs) are multifunctional compounds that act as the basis for the production of various industrial products with broad commercial and pharmaceutical implications. However, the terminal oxygenation of saturated or unsaturated fatty acids for the synthesis of ω-OHFAs is intricate to accomplish through chemocatalysis, due to the selectivity and controlled r...

The antimicrobial effects of natural compounds (caprylic acid, CA; citric acid, CTA; and vanillin, VNL) on the inactivation of Cronobacter sakazakii and Salmonella enterica serovar Typhimurium were examined in reconstituted infant formula. The samples were treated with: 1) CA, CTA, or VNL alone (0, 10, 20, 30, 40, 60, and 80 mM); 2) a combination of CA (10 and 20 mM) and CTA (15 and 30 mM); and...
