Creation and imitation of a milk flavour

Flavour plays a crucial role in food and is the most important aspect of milk. Milk has a pleasant smell and milk flavour can be used in several products. However, how to recreate milk flavour has rarely been reported. Therefore, the creation of milk flavour is of great interest. This study focused on the creation and imitation of milk flavour. The approach to flavour creation involves identifying the attributes of the flavour and developing an impactful, authentic flavour. Accordingly, to create a milk flavour, the notes of milk flavour were identified by smelling and tasting milk. Based on the identified notes, aroma ingredients were selected to blend into a milk-flavour. After olfactory discrimination, several modifications and adjustments were made and a typical milk flavour formula was obtained. The results showed that the milk flavour has the following notes: milky, acidic, vanilla-like, caramel-like, aldehydic, fruity, beany, buttery, meaty, and vegetative. Lactones, acids, aldehydes, alcohols, ketones, esters, sulphur compounds, furans, and nitrogen compounds can provide these notes. Based on the developed formula, a harmonious flavour with typical characteristics of milk was obtained by blending the selected aroma ingredients.

Microwave-assisted extraction and differential scanning calorimetry in the chemical identification of sliming agents apprehended in the south region of Brazil

Over the past decades, consume of slimming agents considerably increased in several countries, including Brazil, due to weight-loss and stimulant properties. Since these drugs are controlled to prevent illicit and indiscriminate use, there is a parallel illegal market that uses the Internet and irregular pharmacies in order to distribute these formulations. Slimming agents produced by these illegal sources are known for being manufactured with little or none quality control resulting in uncertain and unknown formulations. For forensic purposes, apprehended pharmaceuticals have to undergo a process of chemical identification that can be difficult due to its complex matrix. In this sense, application of assisted energies in the extraction step such as microwave irradiation can be a promising method to increase the recuperation of the target molecules of the sample. Therefore, the aim of this research was to identify four slimming agents apprehended in Brazil by means of visual inspection, Fourier Transform Infrared Spectroscopy, Differential Scanning Calorimetry and Gas Chromatography ? Mass Spectrometry. Moreover, the efficiency of solid-liquid extraction and microwave-assisted extraction was compared. It should be noted that our work was one of the few to use Differential Scanning Calorimetry and the application of microwave irradiation in the analysis of apprehended materials. Results showed that the majority of the samples was counterfeit being composed of one or several adulterants or contaminants. Initially, visual inspection resourcefully screened the slimming agents for possible signs of falsification, however it failed to detect fraudulent products that were very similar to veridical medicines. Sequentially, Fourier Transform Infrared Spectroscopy detected functional groups present in the samples while the presence or absence of the alleged active ingredients were successfully measured with Differential Scanning Calorimetry and, thus, providing a full chemical screening of the apprehended materials. Gas Chromatography- Mass Spectrometry confirmed the presence of adulterants such as caffeine, fluoxetine and phenolphthalein as well as contaminants such as sulfurol in the falsified samples. Finally, comparison of extraction procedures indicated that microwave-assisted extraction increased the recovery of compounds detected in chromatographic analysis to a greater extent than solid-liquid extraction.

Lithium-stabilized nucleophilic addition of thiamin to a ketone provides an efficient route to mandelylthiamin, a critical pre-decarboxylation intermediate

Mandelylthiamin (MTh) is an accurate model of the covalent intermediate derived from the condensation of thiamin diphosphate and benzoylformate in benzoylformate decarboxylase. The properties and catalytic susceptibilities of mandelylthiamin are the subjects of considerable interest. However, the existing synthesis gives only trace amounts of the precursor to MTh as it is conducted under reversible conditions. An improved approach derives from the unique ability of lithium ions to drive to completion the otherwise unfavorable condensation of the conjugate base of thiamin and methyl benzoylformate. The unique efficiency of the condensation reaction in the presence of lithium ions is established in contrast to the effects of other Lewis acids. Interpretation of the pattern of the results indicates that the condensation of the ketone and thiamin is thermodynamically controlled. It is proposed that the addition of lithium ions displaces the equilibrium toward the product through formation of a stable lithium-alkoxide.

To investigate the effects of beta-glucosidase on the aroma of flat peach juice, five flat peach juice samples (FPSs), including 1 fresh, 1 pasteurized and 3 enzyme-treated FPS samples, were analyzed by gas chromatography-mass spectrometry (GC-MS) and descriptive sensory analysis (DSA). Fruity, floral, peach-like, cooked, and unnatural were chosen as sensory attributes to evaluate FPS flavors. DSA results indicated a significant difference among the control samples (FPS0 and FPS1) and enzyme-treated samples (FPS2-4) for almost all sensory attributes. Compared to pasteurized sample FPS1, enzyme-treated samples with moderate temperature (FPS2 and FPS3) showed strong floral, fruity, and peach-like attributes, but weaker cooked and unnatural notes. A total of 71 volatiles were identified for comparison and evaluation of the aroma characteristics of FPSs. Partial least squares regression models (PLS1 and PLS2) were performed to analyze the correlation among 71 volatile compounds and DSA data. PLS1 results indicated that fourteen compounds, 2-hexanal, nonanal, (E,E)-2,4-heptadienal, decanal, amyl acetate, ethyl caproate, (Z)-3-hexenyl acetate, gamma-caprolactone, delta-octanolactone, dihydro-beta-ionone, (Z)-3-hexen-1-ol, (E)-6,10-dimethylundeca-5,9-dien-2-one, linalool, and geraniol, showed significant positive contribution to flat peach attribute, and PLS2 further confirmed that using beta-glucosidase under suitable temperatures would be useful for improving the sensory characteristics of FPS.

Starting from the commercially available enantiopure (1S,2S)-2-amino-1- phenyl-1,3-propanediol novel enantiomerically pure benzimidazoles were prepared; N-alkylation gave chiral benzimidazolium salts, which were tested in asymmetric benzoin condensations. The synthesis of conceptually new, enantiomerically pure, C2 symmetric bis-thiazolium and bis-benzimidazolium salts was also developed. These new chiral heterocycles were employed as catalysts in the asymmetric dimerisation of benzaldehyde to give benzoin with moderate enantioselectivity.

The effect of aliphatic aldehydes on Maillard reaction and meaty flavor formation was investigated in cysteinexylose model systems. The Maillard reaction in the absence and presence of hexanal, (E)-2-heptenal, or (E,E)-2,4-decadienal, was carried out at 90?, pH 5.5 for 5 h. Changes in the concentrations of xylose, cysteine, initial reaction intermediates (2-threityl-4-carboxythiazolidine and Amadori rearrangement product of cysteine (Cys-Amadori)) with reaction time were determined by high performance liquid chromatography with evaporate light scattering detection (HPLC-ELSD). Also, changes in the pH and absorbance values at 294 and 420 nm of the reaction mixtures were monitored. Volatile flavor compounds in the 3 h reaction mixtures were compartaively analyzed by solid phase microextraction coupled with gas chromatography and mass spectrometry (SPME-GC-MS). As indicated by decreased concentrations of Cys-Amadori and 2-threityl-4-carboxythiazolidine in the presence of aliphatic aldehydes, all the three aldehydes showed inhibitory effects on the initial stage of the Maillard reaction, among which (E)-2-heptenal was the stongest inhibitor, followed by (E,E)-2,4-decadienal and hexanal. Additionally, hexanal also showed inhibitory effect on the intermediate and final stages of the Maillard reaction, as indicated by decreased absorbance at 294 and 420 nm. However, (E)-2-heptenal and (E,E)-2,4-decadienal accelerated both the intermediate and final stages, as indicated by increased absorbance values at 294 and 420 nm, with the latter being more effective than the former. On the other hand, the reaction systems in the presence of (E)-2-heptenal and (E,E)-2,4-decadienal produced a relatively greater amount of total volatile sulfur-containing compounds than the blank model system, and additionally produced some new alkyl chain sulfur-containing compounds and furane derivatives such as 2-hexylthiophene and 2-propylfuran as detected by GC-MS analysis, due to participation of the aldehydes in cysteine-xylose reaction and reaction of the aldehydes themselves in the buffered cysteine-xylose solution.

Volatile sulfur-containing compounds (VSCs) play an important role in wine aroma conferring at high concentrations unpleasant odors but also participating positively at low concentration. A large number of VSCs are formed at different stages of winemaking and storage. To monitor this phenomenon, a HS-SPME-GC-MS/MS method has been developed. The method is proposed in order to quantify 27 different sulfur-containing compounds. SPME extraction was performed using a carboxen-polydimethylsiloxane (CAR-PDMS) fiber, which resulted the most effective fiber coating. Time and temperature extraction conditions were optimized using response surface methodology. The selectivity and sensitivity of the method were considerably increased using triple-quadrupole in multiple reaction monitoring (MRM) mode. The number of VSCs analyzed in a single run was higher than in any other method previously reported using single-quadrupole MS or other detectors. The overall process was successfully applied to identify and quantify sulfur compounds both in white and red wines.

Descriptive sensory analysis and gas chromatography-mass spectrometry (GC-MS) analysis were conducted to investigate changes in aroma characteristics of beeflike process flavours (BPFs) prepared from enzymatically hydrolyzed beef (beef base) of different DH (degree of hydrolysis) with other ingredients. Five attributes (beefy, meaty, simulate, mouthful and roasted) were selected to assess BPFs. The results of descriptive sensory analysis confirmed that BPF2 from beef base of moderate DH 29.13% was strongest in beefy, meaty and simulate characteristics; BPF4 and BPF5 from beef base of higher DH (40.43% and 44.22%, respectively) were superior in mouthful and roasted attributes respectively; while BPF0 without beef base gave weaker odour for all attributes. Twenty six compounds from GC-MS were selected as specific compounds to represent beef odour based on their odour-active properties assessed by a detection frequency method of GC-O and correlation of their contents with sensory attributes intensity. Correlation analysis of molecular weight (MW) of peptides, odour-active compounds and sensory attributes through partial least squares regression (PLSR) further explained that beef base with DH of 29.13% was a desirable precursor for imparting aroma characteristics of beeflike process flavour.
