The study was aim to investigate the effects of grafting on volatile compounds and sensory quality of black tea. Seven groups of black tea were prepared from one nongrafted tea tree “Yinghong9 (YJ)” and six grafted tea trees by grafting scion of “YingHong9” on different rootstocks. Sensory analysis indicated marked/slight variations among seven samples, among which, the one grafting on HuangZhiXiangDanCong (HZX) stood out with floral and fruity aroma. The result of chemometrics analysis suggested various effects on compounds caused by different rootstocks. A total of 38 differential compounds were identified, showing mainly quantitative variations, with 36 being identified in all samples. The significant higher contents of volatiles, such as geraniol, phenylethyl alcohol, ( E )-nerolidol, decanal, and linalool oxides, in HZX compared with YJ were observed, which explained why floral and fruity aroma stood out among the whole aroma profile of HZX. Both results of sensory and instrumental analysis suggested certain correlation between compound variations and aroma characteristics. Moreover, different rootstocks influenced the aroma quality in different ways. Practical Application In conclusion, the study illuminates the various effects of grafting on the volatile compounds and aroma quality, which enlightens the possibility of changing aroma quality of black tea by grafting scions on different rootstocks. And thus, it can help guide the practical production when cultivating new varieties.

The impact of gum arabic (GA) (10 and 15% w/v) on the quality and postharvest-shelf life of strawberry at storage condition of 4 ± 1°C for 10 days were evaluated. Significant ( p < .05) differences were found for the overall 15% GA-coating as compared with the control. The application of GA-coatings maintained the total contents of phenolic, anthocyanin and total soluble solid (TSS) but significantly ( p < .05) retarded the increase in polyphenol oxidase (PPO) activity, reduced weight loss, and completely inhibited fungal infections. Moreover, the 15% GA edible coating retained the color, improved the firmness, and increased antioxidant activity compared with control. Likewise, sensory analysis results also showed the effectiveness of 15% GA-coating by retaining the quality of strawberry fruits. The results show that 15% of GA-coating can be an effective strategy for enhancing the quality of strawberry fruits during cold storage without any negative effect. Practical applications The edible coating has demonstrated to be a promising food preservation method and is progressively used for the commercial processing of many fruits and vegetables. However, gum arabic has not been used for preserving the quality of highly perishable fruit such as strawberries. The result suggests that gum arabic coatings can be a valuable biochemical means of preserving strawberries during refrigerated storage and could be used as an alternative to the synthetic formulas of fruit and vegetable packaging. Thus, gum arabic coating could provide horticultural and food processors a useful way to improve the quality, prolong shelf life, and marketing strategy.

Marinating is a Chinese meat-processing technique that involves treating meat products in an aged brine containing traditional Chinese spices and other condiments. In this study, beef meats were marinated in different seasoning recipes, including marinade solution of water as control (BS1), marinade solution consisting of water and 2% salt (BS2), marinade solution consisting of water, 2% salt, and 0.5% sugar (BS3), and marinade solution consisting of water, 2% salt, 0.5% sugar, 0.5% soy sauce, and spices (BS4). The effects of different marinade solutions through the tumbling on the flavor profile of roasted beef meat were comprehensively analyzed via chemical and sensory analysis. A total of 82 volatile flavor compounds were identified. Among them, 36 compounds were identified in BS1, 40 compounds in BS2, 46 compounds in BS3, and 64 compounds in BS4. Besides, 4 compounds showed high odor activity values (OAVs) in marinated samples, including decanal, trans -2-decenal, linalool, and nonanal. The metal oxide sensors of E-nose distinguished the differences among the different marinated samples. Marinated beef samples BS2 and BS3 showed a significant increase in the values of thiobarbituric acid reactive substances (TBARS). In contrast, marinated beef sample BS4 significantly reduced TBARS value to 4.11 µg MDA/kg beef. It can be concluded that using this different seasoning processing enhances the aroma profile and provides a reference for the production of marinated meat products. Practical applications Marinating is a Chinese meat-processing technique that involves treating meat products in an aged brine containing traditional Chinese spices and other condiments. Processing beef meat with different marinade solutions could enhance its aroma profile. Therefore, this study aimed to evaluate the effect of marination in different marinade solutions through the tumbling on the volatile flavor compounds of roasted beef meat using HS-SPME-GC-MS and E-nose. The obtained results from this study could enrich the theoretical knowledge of the flavor chemistry of marinated beef meat and provide a reference for the production of marinated meat products.

Taste is one of the main chicken soup characteristic quality factors as it affects palatability as well as consumer acceptability. Metabolomics coupled with sensory analysis method were applied to explore the differences of taste-chemical compositions in chicken carcasses and their correlation to the sensory qualities. Results showed that organic acid were the main taste compounds contained in the five kinds of chicken soup samples. The umami taste intensity of chicken breast meat soup was significantly higher than that of the other four parts (p < 0.05). Seven organic acids (oxalic acid, tartaric acid, formic acid, lactic acid, acetic acid, citric acid, and succinic acid) and a small peptide (anserine) were the main differential taste compounds among chicken soup with five different parts, and they contributed significantly to the taste of chicken soup (taste activity value (TAV) >1).

To improve the functional property and flavor quality of kiwi wine, the performance of 11 strains of non- Saccharomyces yeasts from 5 species were comprehensively characterized in kiwi wine. Chemical compositions and sensorial profiles of all kiwi wines were assessed. The results indicated that most non- Saccharomyces cerevisiae produced more polyphenols than Saccharomyces cerevisiae WLS21 (Sc21). A total of 130 volatiles were observed in the kiwi wines. Zygosaccharomyces rouxii IFO30 (Zr30), Zygosaccharomyces bailii IFO37 (Zb37) and Schizosaccharomyces pombe 1757 (Sp57) were found to produce more concentration of volatile compounds than the other strains including Sc21. 25 volatiles with a rOAV ≥0.1 were identified. Principal component analysis (PCA) revealed that Zr30 and Zb37 specifically increased the concentrations of ethyl esters, 2-methylbutan-1-ol and phenethyl acetate, while Sp57 primarily enhanced the contents of phenylacetaldehyde, 2-methylbutan-1-ol and phenethyl acetate. The sensory analysis demonstrated that Zr30 and Zb37 strains were more optimal than S. cerevisiae in aroma generation. In addition, the partial least-squares regression (PLSR) analysis revealed that tropical fruits, red fruits, dried fruits, flowers and floral odors showed an intensely positive impact on the overall acceptability of the kiwi wine.

This work aims to explore the contribution of prickly ash (Zanthoxylum bungeanumMaxim) on the taste perception of stewed sheep tail fat. Liquid chromatography-tandem quadrupole time of flight mass spectrometry (LC-QTOF-MS) was applied to analyze the taste-related compounds. A total of 99 compounds in different sheep tail fat samples were identified. The semi-quantitative results showed that there were differences between the samples. The partial least squares discriminant analysis (PLS-DA) model without overfitting was used to investigate the effect of prickly ash. Eleven marker compounds were predicted with a variable importance for projection > 1, fold change > 2 andp< 0.05. An additional experiment showed that guanosine 5′-monophosphate, malic acid, inosine and adenosine 5′-monophosphate could improve the umami and saltiness taste of stewed sheep tail fat.Keywords:sheep tail fat;taste compounds;LC-QTOF-MS;PLS-DA;sensory analysis;additional experiment

The objective of this study was to identify the released behavior of odor-active compounds of Pu-erh tea during the water-boiling extraction, as well as to explore the feasibility of aroma recovery using absorption oils. The behavior of odor-active compounds was identified by using piecewise recovered condensed water combined with sensory, GC-O, and GC–MS analysis. The power-function type kinetic model was the model that best fitted odor intensities, alcohols, methoxy-phenolics, esters, aldehydes, ketones, and total compounds of condensed water. The sensory quality of the condensed water was the best when 16% of added water was evaporated. Six absorption oils were evaluated, and paraffin oil (35 cSt) performed the best in terms of both absorption efficiency and sensory quality of the essential oil. Under the optimized conditions, the absorption and recovery efficiency of odor compounds reached 54.49% and 39.52%, respectively. The alcohols, aldehydes, and methoxy-phenolics exhibited higher absorption and recovery efficiency.

New insight was systematically elucidated on variations of overall flavor characteristics in shiitake mushrooms ( Lentinula edodes ) affected by different drying techniques (hot air-drying (HD), vacuum freeze-drying (VFD), and VFD combined with HD (VFD-HD)). The volatile fingerprints of shiitake mushrooms were successfully established by headspace-gas chromatography-ion mobility spectrometry (HS-GC-IMS), and taste profiles and concentrations of non-volatile substances in mushrooms were analyzed. Comparison of aroma fingerprints associated with three drying approaches demonstrated that HD caused considerable losses of volatile compounds except for volatile acids, while VFD and VFD-HD preserved aroma compounds effectively. By application of PLSR analysis, strong “seasoning-like” and “fruity” aromas of VFD-HD mushrooms were closely correlated with 2,6-dimethylpyrazine and esters respectively. Additionally, the umami intensity of VFD-HD mushrooms was similar to HD samples and significantly higher than VFD ones. Furthermore, the correlation between the electronic tongue and sensory attributes was explored. The results obtained from this study revealed that VFD-HD could combine the advantages of single HD and VFD, producing high flavor quality mushroom products.

Qingke baijiu is a typical light-flavor baijiu and considered as one of the geographical indication products in China. The aroma of newly fermented original Qingke baijiu is unique and popular with consumers. In this work, the key aroma-active compounds of original Qingke baijiu (QKJ) were characterized by combined instrument analysis with sensory analysis. A total of 54 aroma compounds with high flavor dilution factors (FD values≥ 9) were screened out by gas chromatography–olfactometry (GC–O) combined with aroma extract dilution analysis (AEDA). After quantitation, 28 aroma-active compounds had odorant activity values (OAVs) > 1 in QKJ. Recombinant and omission experiments further proved that the esters and alcohols, especially ethyl lactate, phenylethyl acetate, ethyl hexanoate , 2-methyl-1-butanol, ethyl acetate , γ -nonalactone and 2,3-dimethyl-5-ethyl pyrazine were critical to the flavor of QKJ. Consequently, this research reveals the characteristics of QKJ and provides theoretical support for production and quality control assurance.

The mixed fermentation of non- Saccharomyces yeasts with Saccharomyces cerevisiae ( S. cerevisiae ) is regarded as a promising strategy to improve the quality of fruit wine. In this study, we investigated the effects of sequential inoculation fermentation involving four non- Saccharomyces yeast species ( Tourlaspora delbrueckii ( T.d. ), Metschnikowia pulcherrima ( M.p. ), Schizosaccharomyces pombe ( S.p. ) and Issatchenkia terricola ( I.t. )) and an S. cerevisiae strain on the physiochemical properties, volatile compounds and sensory profiling of strawberry wine. The sequential fermentations exhibited a significant reduction in ethanol and organic acids content, while free amino acids content increased by 0.28–3.74 times, particularly in the M.p.+S.c. group. The GC-IMS identified 68 volatile compounds, among which isoamyl acetate, ethyl hexanoate, and isobutanol were found to be the predominant volatiles of strawberry wine. Samples more frequently characterized as “strawberry”, “honey” and “preserved fruit” in Check-all-that-apply analysis were preferred by the panelists ( n = 93). The I.t.+S.c. elicited emotional responses of “fascinated” and “surprised” leading to a higher liking rating. Furthermore, the PLSR analysis demonstrated a significant contribution of esters and higher alcohols, such as ethyl 3-methylbutanoate-D, ethyl propanoate, along with isoamyl acetate-D, to the fruity and sweet notes. The present study provided useful information into the mixed inoculation fermentation strategy, which involves combining appropriate non- Saccharomyces yeasts with S. cerevisiae , for developing distinct styles and enhancing the oenological quality of strawberry wine.

Qu -aroma is of great significance for evaluation the quality of Daqu starter. This study aimed to decode the Qu -aroma of medium-temperature Daqu (MT- Daqu ) via “top-down” and “bottom-up” approaches. Firstly, 52 aroma descriptors were defined to describe the MT- Daqu aroma by quantitative descriptive analysis . Secondly, 193 volatile organic compounds (VOCs) were identified from 42 MT- Daqu samples by HS-SPME-GC–MS, and 43 dominant VOCs were screened out by frequence of occurrence or abundance. By Thin Film (TF)-SPME-GC-O-MS, 27 odors and 90 VOCs were detected in MT- Daqu mixture, and 14 odor-active VOCs were screened out by odor intensity. Thirdly, a five-level MT- Daqu aroma wheel was constructed by matching 52 aroma descriptors and 37 aroma-active VOCs. Finally, Qu -aroma of MT- Daqu was reconstructed with 37 aroma-active VOCs and evaluated by omission experiments. Hereinto, 26 key aroma-active VOCs were determined by OAV value ≥1, including isovaleric acid, 1-hexanol, isovaleraldehyde, 2-octanone, trimethylpyrazine, γ-nonalactone, 4-vinylguaiacol, etc.

The main objective of this study was to optimize the fermentation conditions of goji and to analyze the sugar, organic acid, amino acid, and flavor compounds before and after the fermentation of goji. Based on the single-factor experiment, orthogonal array design and the range analysis, the optimized conditions for fermented goji were 30% raw material concentration, 28 h fermentation time and 0.05% inoculum size, respectively. Under optimal conditions, the biomass of Lactiplantibacillus plantarum NCU137 and sensory score of fermented goji reached to 8.84 ± 0.05 log CFU/g and 81.3 ± 1.5, respectively. After fermentation, the content of malate, succinic acid, and lactate increased, while the content of pyruvate, glucose, fructose, and the overall free amino acid decreased. After fermentation, volatile components except for the phenols and acids are declining. This study would provide theoretical basis and experimental data for the industrialization of Lycium barbarum fermentation. Novelty impact statement After Lactiplantibacillus plantarum NCU137 fermentation, the contents of organic acids and total acidity acid in fermented goji significantly increased, which could inhibit microbiological spoilage and growth. Moreover, we get a delicious fermented goji juice through the optimization of fermentation conditions. Therefore, the data obtained in this study provides a better understanding of the effects of raw material content, fermentation time, and inoculum size on the quality of fermented goji, which would be very beneficial for the production of high-quality fermented goji for subsequent consumption.
