Butanoic acid (No.1) detected in the non-fermented pork jerky wass not found in the pork jerky.
Conversion of the methionine hydroxy analogue DL-2- hydroxy-(4-methylthio)
butanoic acid to sulphur-containing amino acids in the chicken small intestine.
Other identified volatiles found in this study were pyrazines (2-methyl and 2,5-dimethyl),
butanoic acid and 2(5H)-furanone.
2-Benzamido-4-methylpentanoic acid-2-cyclohexyl carboxamide (2-BMCA), 2-{[2-(cyclohexycarbamoyl) benzoyl] amino}-4-(methylsulfanyl)
butanoic acid (2CA4MBA), 2-{[2-(cyclohexylcarbamoyl) benzoyl] amino}-3-methylbutanoic acid(2CA3MBA), 2-{[2-(cyclohexycarbamoyl) benzoyl] amino} propanoic acid(2CMPA), and 2-Benzamido acetic acid 2- cyclohexyl carboxamide (2BA2C).
A 5-day fermentation period of the Forastero cacao yielded predominant amounts of floral and sweet aroma volatiles such as epoxylinalool, pentanoic acid, benzeneacetaldehyde, and benzaldehyde but compounds with potential undesirable rancid, fatty, fishy, cheesy, and acid aroma including
butanoic acid, hexanoic acid, pyridine, heptanoic acid, and peracetic acid as well as 1-phenylpent-4-en-2-ol with no aroma record were also among the main compounds found in fermented samples of this cultivar (Figure 1).
Among them, acetic acid, 3-(methylthio)propanal (methional), 2-methylpropanoic acid,
butanoic acid, 3-methyl-butanoic acid, 4-hydroxy-2,5-dimethyl-3( 2H )-furanone (HDMF), 4-hydroxy-2-ethyl-5-methyl-3(2H)-furanone (HEMF) and 2-phenylacetic acid had the highest flavor dilution factors.

butanoic acid (0.35%), hexadecanoic acid (0.29%), propanoic acid (0.15%), 9-octadecenamide (0.13%), benzene acetic acid (0.09%) and 4-(1-1-dimethyl ethyl)-methyl acetate (0.08%) (Fig.
2-(5-Amino-2-oxo-1, 2-dihydrospiro (indole-3, 3-(1, 2, 4) triazol)-4(2H)-yl)-4-(methylsulfanyl)

The broiler growth performance and immune response were determined by using different doses of liquid dl-2-hydroxy-4-methylthio
butanoic acid (LMA).
* the testing of and factors related to the biodegradability of poly(hydroxy
butanoic acid) (PHB) copolymers in various environments--including soil, fresh water, seawater, compost, and anaerobic digesters (Xiudong Sun, Telles);
