Application


  • Characterization of key aroma compounds of fried pepper sauce under different pretreatment processes.: This study identifies the key aroma compounds in fried pepper sauce, highlighting methional′s role in contributing to the sauce′s overall flavor profile. The research underscores methional′s importance in food chemistry and its potential applications in flavor enhancement and food product development (Luo et al., 2024).

Biochem/physiol Actions

Odor at 0.1%
Taste at 5 ppb-5 ppm

General description

Methional is the main sulfur-containing flavor compound in potatoes.

Other Notes

A novel technology (Olfactoscan screening) was applied to screen for volatiles including saturated aldehydes that mask the perception of methional, an off-flavor commonly found in orange juice. For the screening experiment, methional odor pulses were generated by an olfactometer and

Lactic acid bacteria were screened for methional production from 4-methylthio-2-ketobutanoate. Only Lactococcus lactis IFPL730 produced high amounts of methional. It was demonstrated that production of this compound was an exclusively enzymatic reaction. The present work describes for the first time

Three tasty (BR-139, FA-624, and FA-612) and two less tasty (R-144 and R-175) fresh greenhouse tomato cultivars, which significantly differ in their flavor profiles, were screened for potent odorants using aroma extract dilution analysis (AEDA). On the basis of AEDA

Carcinogenic benzo[a]pyrene (BP) is generally considered to show genotoxicity by forming DNA adducts of its metabolite, BP-7,8-diol-9,10-epoxide. We investigated oxidative DNA damage and its sequence specificity induced by BP-7,8-dione, another metabolite of BP, using (32)P-5'-end-labeled DNA.
