Astuti, Retno Dwi published the artcileThe Volatile Compounds and Aroma Description in Various Rhizopus oligosporus Solid-State Fermented and Nonfermented Rice Bran, Name: Isobutyl palmitate, the publication is Fermentation (2022), 8(3), 120, database is CAplus.

Rice bran is known to have beneficial nutrients. Current studies suggest that solid-state fermentation affects the rice bran’s volatile profile. The aim of this study is to identify the volatile compounds and aroma description of fermented and nonfermented rice bran (FRB and NFRB) of Ciherang, Inpari30, IR64 and Inpari42. The fermentation was conducted using Rhizopus oligosporus solid-state fermentation Headspace-solid phase microextraction coupled with GC/MS was performed, and the aroma was translated by 10 trained panelists through quant. descriptive anal. (QDA). The result showed that 72 and 68 compounds were identified in FRB and NFRB, resp. They are aldehydes, ketones, alcs., acids, esters, fatty acid, phenol, benzenes, furan, thiazole, pyrazines, pyridine, lactones, terpenes, and hydrocarbons. The PCA showed that FRB was dominated by alcs., whereas NFRB was dominated by aldehydes. The QDA described nine aromas, i.e., rancid, smoky, musty, grassy, green, earthy, cereal, and sweet in NFRB. The fermentation process added fermented attributes to the aroma description to FRB and enhanced the rancid, smoky, and musty aromas. These studies indicated that fermented rice bran might increase the volatile compound of rice bran. Thus, it may provide opportunities to develop the production of fermented rice bran as a functional ingredient.

Schulz, Stefan published the artcileAn Antiaphrodisiac in Heliconius melpomene Butterflies, Recommanded Product: Isobutyl palmitate, the publication is Journal of Chemical Ecology (2008), 34(1), 82-93, database is CAplus and MEDLINE.

Gilbert (1976) suggested that male-contributed odors of mated females of Heliconius erato could enforce monogamy. The authors investigated the pheromone system of a relative, Heliconius melpomene, using chem. anal., behavioral experiments, and feeding experiments with labeled biosynthetic pheromone precursors. The abdominal scent glands of males contained a complex odor bouquet, consisting of the volatile compound (E)-β-ocimene together with some trace components and a less volatile matrix made up predominately of esters of common C₁₆– and C₁₈-fatty acids with the alcs. ethanol, 2-propanol, 1-butanol, isobutanol, 1-hexanol, and (Z)-3-hexenol. This bouquet is formed during the first days after eclosion, and transferred during copulation to the females. Virgin female scent glands do not contain these compounds The transfer of ocimene and the esters was shown by anal. of butterflies of both sexes before and after copulation. Addnl. proof was obtained by males fed with labeled D–¹³C₆– glucose. They produced ¹³C-labeled ocimene and transferred it to females during copulation. Behavioral tests with ocimene applied to unmated females showed its repellency to males. The esters did not show such activity, but they moderated the evaporation rate of ocimene. The authors’ investigation showed that β-ocimene is an antiaphrodisiac pheromone of H. melpomene.

Berger, Ralf G. published the artcileThe flavor of cape gooseberry (Physalis peruviana L.), SDS of cas: 110-34-9, the publication is Zeitschrift fuer Lebensmittel-Untersuchung und -Forschung (1989), 188(2), 122-6, database is CAplus.

The volatile constituents of cape gooseberry (P. peruviana) were characterized after liquid/liquid extraction and fractionation of the flavor concentrates on SiO₂ gel by high resolution gas chromatog. and coupled gas chromatog.-mass spectrometry. Sniffing gas chromatog. on serially diluted extracts showed Me 2-methylbutyrate, 2,5-dimethyl-4-hydroxy-3(2H)-furanone and its 4-methoxy derivative, 4- and 5-octanolide, β-ionone, and β-damascenone to be impact components. The nonvolatile flavor fraction contained glucose, fructose, sucrose, citric acid, and smaller amounts of organic aliphatic and benzoic acids. The bound forms of volatiles were dominated by benzyl alc., 2-methylpropanol, and 2-methylbutanol. The presence of high amounts of activated acyl moieties in the fruit was concluded indirectly from various data.

Sen, Supriyo published the artcileChemometric analysis reveals links in the formation of fragrant bio-molecules during agarwood (Aquilaria malaccensis) and fungal interactions, Application of Isobutyl palmitate, the publication is Scientific Reports (2017), 44406, database is CAplus and MEDLINE.

Fragrant agarwood, arguably the costliest wood in the world, is formed by plant-fungal interactions in Aquilaria spp. However, very little is known about this fragrant outcome of interaction. Therefore, mimicking the ancient traditions of agarwood production in Assam (Northeast India), a chemometric assessment of the agarwood-fungus interaction was made by chem. profiling (GC-MS) coupled with statistical anal. (principal component, correlation network anal.) across three platforms, viz. callus, juvenile plants and resinous wood-chips with an associated Fusarium. In the study of callus-fungus interaction, increased accumulation of key aroma compounds such as pentatriacontane {fold change (log2FC) = 3.47}, 17-pentatriacontene (log2FC = 2.95), tetradecane, 2-methyl- (log2FC = 1.10) over callus and activation of pathways related to defense and secondary metabolism indicated links to aroma production Study on fungal interactions in juvenile plants and resinous wood-chips indicated formation of terpenoid precursors (e.g. farnesol, geranylgeraniol acetate) and agarwood sesquiterpenes (e.g. agarospirol, γ-eudesmol). Correlation network anal. revealed the possible regulation of sesquiterpene biosynthesis involving squalene. Also a direct role of fungus in aroma (e.g. dodecane, 4-methyl-, tetracosane) was highlighted. Appearance of fragrant mols. unknown to agarwood during interaction featured as a new possibility for future research.

Griffith, W. L. published the artcileNovel neutral solvents fermentations, Related Products of esters-buliding-blocks, the publication is Developments in Industrial Microbiology Series (1983), 347-52, database is CAplus.

Earlier fermentations producing neutral solvents generally have been single-stage batch fermentations with distillation for product recovery. One step in this group of fermentations, the production of BuOH [71-36-3], provides the major rate and concentration limitation of the product. The organic/aqueous distribution coefficients of a number of potential BuOH extractants were measured and tested several in culture. The most effective appeared to be polyoxyalkylene ethers, which had distribution coefficients in the range of 1.5-3 and showed little or no fermentation toxicity. The esters and alcs. tested generally had better distribution coefficients but higher biotoxicity. Pressurization of the fermentation vessel with H₂ appeared to decrease, rather than increase, the formation of neutral solvents.

Nan, Li-jun published the artcileEffect of trellises on aroma compounds of dry white wines, Recommanded Product: Isobutyl palmitate, the publication is Shipin Kexue (Beijing, China) (2014), 35(4), 101-106, database is CAplus.

The aim of this study was to establish a new pruning system for dormant grapevines. The traditional independent long-stem pruning (ILSP) was used as control to compare the effect of single crawled cordon training (SCCT) on the aroma compounds of Ecolly dry white wine. The aroma compounds of dry white wines from Ecolly grapes harvested at three time points (80, 90 and 120 days) after anthesis were extracted by solid-phase micro-extraction and analyzed by gas chromatog.-mass spectrometry (GC-MS). A total of 30 compounds with contents ranging from 3.9 μg to 1.5311 mg and a total amount of 14.0407 mg were identified in these wine samples. Esters were accumulated mainly by ILSP except for ethanol esters at 80 days after anthesis. SCCT led to higher contents of higher alcs., ethanol esters and organic acids than ILSP at 80 days after anthesis whereas ILSP wines brewed at 120 days after anthesis displayed more complex aroma characteristics. SCCT could improve the earlier accumulation of aroma compounds in wine and guarantee the stable yield and quality of wine, thereby favoring the sustainable development of wine industry.

Objective: To find out and expand the utilization potential of Phallus impudicus L. by analyzing the chem. composition of petroleum ether and ethanol extracts from its pileus, stipe and volva. Methods: The volatile components of the pileus, stipe and volva of Phallus impudicus L. were obtained by successive extraction with petroleum ether and ethanol under room temperature (25-30°C). The chem. composition of each extract was identified by gas chromatog.-mass spectrometry (GC-MS) using a polar column HP-INNOWAX. Temperature programming was as follows: initial temperature was set to 60°C hold for 2 min, followed by an increase of 10°C/min to 160°C held for 6 min, and another increase of 3°C/min to 220°C held for 17 min. The spectra were compared with those published in the mass spectral library NIST 08. Results: A total of 67 volatile components were identified from the two different solvent extracts of Phallus impudicus L., 66 compounds of which were first reported in this study. A total of 35 compounds were extracted with petroleum ether from Phallus impudicus L., 24, 18 and 18 of which were identified from the extracts of pileus, stipe and volva, resp. A total of 38 components were extracted from Phallus impudicus L. including 26, 28 and 12 compounds identified from the extracts of pileus, stipe and volva, resp. Conclusions: The presence of 9,12-octadecadienoic acid (Z,Z)-, butylated hydroxytoluene, 1,2-benzenedicarboxylic acid, bis(2-methylpropyl) ester, isosorbide, 1,2-cyclopentanedione, 2-pyrrolidinone, niacinamide, 9,12-octadecadienoic acid, and Et ester can provide the scientific basis for reasonable utilization of Phallus impudicus L.
