Abstract:
... In the last few years organoleptic and nutritional traits have become the major breeding targets in most strawberry breeding programs all over the world. Furthermore, the joint improvement of the nutritional value and the sensory key parameters of strawberry might increase the consumption rate of this fruit, which in turn will have a positive effect on consumer's health and a positive economic imp ...
... Abscisic acid (ABA) is crucial in fruit maturation and senescence and is considered as the other ripening control factor other than ethylene. Important components in ripening fruit are soluble sugars, which make the fruit sweeter and carotenoids, important flavor compounds in ripened fruit. The purpose of this study was to examine the effects of foliar ABA and calcium (Ca) fertilizer treatments (i ...

Abstract:
... The complex mixture of volatile organic compounds (VOCs) present in the headspace of Trappist and craft beers was studied to illustrate the efficiency of thermal desorption (TD) comprehensive two-dimensional gas chromatography time-of-flight mass spectrometry (GC×GC-TOFMS) for highlighting subtle differences between highly complex mixtures of VOCs. Headspace solid-phase microextraction (HS-SPME), ...
... Soy sauce contains a variety of volatiles that are highly valuable to its quality with regard to sensory characteristics. This paper describes the analysis of volatile compounds influencing the flavor quality of Chinese-type soy sauces. Gas chromatography–mass spectrometry (GC–MS) combined with headspace-solid phase microextraction and electronic nose (E-nose) were applied for identifying the vola ...

Abstract:
... Diacetyl is a natural fermentation by-product and is an important flavor component of certain liquors. This paper aims to validate the high performance liquid chromatography (HPLC) method based on derivatization with 1,2-diaminobenzene for diacetyl quantification in liquor samples. A limit of quantitation of 0.039 mg/L was obtained. Coefficient regression (R²) of calibration curve for the HPLC–UV ...
... Hickory milk and reconstituted milk (about 12 g/100 g total solid) were mixed in the proportion of 3:7 by volume to prepare hickory milk yogurt. Cow milk yogurt was used as control. The acidity and total count of lactic acid bacteria of hickory milk yogurt were not significantly different from cow milk yogurt (p > 0.05). Compared with cow milk yogurt, hickory milk yogurt had higher total solids, f ...
... Fortification of queso blanco (QB) with flaxseed oil (FO) containing omega‐3 polyunsaturated fatty acids may provide a functional food with health benefits such as improved cell, brain, and retina functionality, and protection against cardiovascular and immune‐inflammatory diseases. However, QB experiences a short shelf life because of the early development of yeasts and molds and addition of FO m ...
... The use of starter cultures (Tetragenococcus halophilus TS71, Zygosaccharomyces rouxii A22, and Meyerozyma (Pichia) guilliermondii EM1Y52) in reduced-salt moromi fermentation was investigated. Reduced-salt moromi fermentation (12%NaCl) with starter cultures was monitored for changes of microbiological and biochemical properties including volatile flavor compounds (VFCs) and biogenic amines (BAs) d ...
... A targeted approach using HS-SPME-GC-MS was performed to compare flavour compounds of ‘Navelina’ and ‘Salustiana’ orange cultivars from organic and conventional management systems. Both varieties of conventional oranges showed higher content of ester compounds. On the other hand, higher content of some compounds related with the geranyl-diphosphate pathway (neryl and geranyl acetates) and some ter ...
... The aim of this study was to investigate the possibility of using tomato and red pepper pomaces for the production eight-carbon volatiles by Trichoderma atroviride and Aspergillus sojae. The fermentation of tomato and pepper pomace-based media by both moulds was conducted in shake flasks and bioreactors. Microbial growth behaviours and fermentation abilities of T. atroviride and A. sojae under bot ...
... Products that bear the label “natural” have gained more attention in the marketplace. In this approach, the production of aroma compounds through biotransformation or bioconversion has been receiving more incentives in economic and research fields. Among the substrates used in these processes, terpenes can be highlighted for their versatility and low cost; some examples are limonene, α-pinene, and ...
... Three fungal endophytes from the genus Nodulisporium were studied for volatile organic compound (VOC) production. All three fungi grew on a wide range of carbon substrates ranging from simple sugars to waste biomass sources. The fungi synthesized a number of long and short-chain VOCs, including eucalyptol; 1-butanol, 3-methyl; 1-octen-3-ol; and benzaldehyde, all with potential applications as biof ...

Abstract:
... Protein and its degradation products are the main nutrients and flavor precursors in pork products. In this study, protein, total nitrogen (TN), water‐soluble nitrogen (WSN), peptides, and free amino acids (FAAs) were analyzed during the production process of Chinese traditional dry‐cured bacon, “Laròu.” Results indicated that the TN content showed no significant changes throughout the whole proce ...

Abstract:
... The volatile constituents of cocoa liquor and the differences between cocoa liquors from different origins were studied. Direct solvent extraction-solvent assisted flavor evaporation and gas chromatography-olfactrometry-mass spectrometry in conjunction with aroma extract dilution analysis were used to identify the key flavor compounds in five cocoa liquors. There were significant differences of sp ...
... ObjectivesConsumers have varied preferences for beef flavor and it is known that dry-aging changes the flavor profile of beef. Therefore, the objective of this study was to characterize flavor differences and compositional changes of ground beef blends with varying levels of dry-aged beef. Materials and MethodsBeef shoulder clods were collected from a commercial processing facility and ground to c ...
... The aroma-active compounds in three Chinese Moutai liquors, aged 1 year, 15 years and 30 years were investigated in this study. The aroma compounds were analysed by gas chromatography–olfactometry (GC–O) coupled with gas chromatography–mass spectrometry (GC–MS). A total of 79 aroma compounds were identified. Aroma extract dilution analysis (AEDA) was further employed to identify the aroma-active c ...
... In Japan, many flavors of instant soup stock (dashi) are available and are often chosen on the basis of preference, the type of dish being prepared, and dietary habits of individuals. However, the complete characterization of all flavor components in Japanese instant dashi is unknown. Therefore, in the present study, we characterized the flavor components (free amino acids and 5′-ribonucleotides) ...
... Application of the sensomics concept elucidated the key odorants of heat-processed licorice (Succus Liquiritiae). Forty-nine aroma-active compounds with flavor dilution (FD) factors between 16 and 2048 were detected; 47 thereof were identified, 23 for the first time in heated licorice. 4-Hydroxy-2,5-dimethylfuran-3(2H)-one revealed the highest FD factor of 2048, followed by 3-hydroxy-4,5-dimethylf ...
