Microbial succession and exploration of higher alcohols-producing core bacteria in northern Huangjiu fermentation [PDF]
AMB Express, 2022 Higher alcohols (HAs) are abundant compounds that provide important flavors in Huangjiu, but they also cause hangover. Previous studies have shown the production of HAs to be related to yeast, but the correlations between HAs and other microorganisms are

Development of Multifunctional Catalysts for the Direct Hydrogenation of Carbon Dioxide to Higher Alcohols. [PDF]
MoleculesThe direct hydrogenation of greenhouse gas CO2 to higher alcohols (C2+OH) provides a new route for the production of high-value chemicals. Due to the difficulty of C-C coupling, the formation of higher alcohols is more difficult compared to that of other

Catalytic Synthesis of Higher Alcohols
, 2016 This thesis deals with the synthesis of higher alcohols using modified Cu/ZnO catalysts. The rate-limiting step for this type of catalyst is regarded as C1 to C2 chain growth step. Therefore the strategy was to mix ethanol with the synthesis gas, in order to propagate the chain growth from this step. Screening of parameters is both batch and continuous-

Conversion of CO2 to higher alcohols
, 2020 I rapporten framgår det en termodynamisk analys för reverse water gas shift med att sammanmata etanol för att undvika det långsammaste steget i reaktionen för att producera högre alkoholer. Ifrån ett termodynamiskt perspektiv, verkar det möjligt att utgå ifrån reverse water gas shift för att producera högre alkoholer vid 100 bar med en temperatur på ...

Study of the volatile fraction of distillates with added donkey thistle (Onopordum acanthium L.) extracts [PDF]
Journal of Central European Agriculture, 2021 ethanol extracts of donkey thistle (Onopordum acanthium L.) was conducted. The extracts were added to the pure distillate from the grapes of Melnik-55 grapevine variety in amounts of 20, 50, 80, 100, 200, 400 and 600 ml. The remaining amount to liter was

Formation, Losses, Preservation and Recovery of Aroma Compounds in the Winemaking Process
Fermentation, 2022 A wine’s aroma profile is an important part of the criteria affecting wine acceptability by consumers. Its characterisation is complex because volatile molecules usually belong to different classes such as alcohols, esters, aldehydes, acids, terpenes ...

Effect of added sulphur dioxide levels on the aroma characteristics of wines from Panciu wine region
Agricultural Science, 2022 In the wine-making process, the yeasts form over 20 higher alcohols that improve the sensation of pala-tine veil for the wine. The amount of higher alcohols is lower for white and rosé wines obtained from clarified musts fermented at moderate ...

Studies on the Higher Fatty Alcohols
Journal of the agricultural chemical society of Japan, 1952 1) Unsaturated-long chain fatty alcohols were prepared in good yield by the reduction of cotton-seed and poppy-seed oils with sodium and ethylene glycol monoethyl ether (Cellosolve) in toluene. 2) These alcohols were fractionated by vacuum distillation and characterized by the deter-mination of iodine and hydroxyl values.

Scientific Aspects of Identification Criteria for Fruit Distillates [PDF]
Техника и технология пищевых производств, 2021 Introduction. Beverages based on fruit distillates belong to elite alcoholic drinks. As a result, there is a high risk of counterfeit. Controlled indicators do not allow identifying distillates by the type of raw material.
