Irisin-Associated Neuroprotective as well as Rehabilitative Approaches for Cerebrovascular event.
These effects started from the addition of subthreshold concentration of chemesthetic flavor ingredients and further increased with increasing the concentration of chemesthetic flavor ingredients added. By adding the subthreshold concentration of chemesthetic flavor ingredients, the flavor lastingness was increased by 32% for mint flavor and 22% for watermelon flavor. The acceptability of these weak-flavored soft chewable candy test samples was significantly increased towards 'just right' with increasing concentrations of chemesthetic flavor ingredients, even at subthreshold level. However, chew time and saliva flow rate were not affected by the addition of chemesthetic flavor ingredients. The increased flavor lastingness by the addition of chemesthetic flavor ingredients could therefore be explained by perceptual interaction between chemesthesis and flavor perception.Gastronomy is one of the cultural emblems of each region and represents the way each society feeds. The aim of this article was to understand the cross-cultural representations of the concept of gastronomy among consumers in Argentina (ARG) and Mexico (MEX). A survey in which 479 consumers of both countries were recruited (ARG = 249, MEX = 230), who had to complete a word association task, was designed. selleck chemicals Words were grouped into categories and the differences in the frequency of mention were analyzed with the Chi Square test. Furthermore, results were analyzed to identify the central core and the peripheral areas of the social representations. Cognitive Salience Index (CSI) was calculated to determine the most important representations. The representations of the gastronomy concept in both countries indicate a strong link to culture, food, pleasure by eating and sensory characteristics of foods and dishes. However, the field of representation, the hierarchy of representations and the cognitive and attitudinal importance were different among Mexican and Argentine consumers, which suggests that gastronomy promotion campaigns for both countries should be oriented according to consumers' perceptions.Red kidney bean coat (RKBC) extract contains bioactive compounds that are known to exhibit anti-melanoma activity in vitro. However, knowledge on antitumor component and mechanism of RKBC extract has not been fully clarified. Here, RKBC extract was portioned with different solvent sequentially, and based on the cell viability assay, cell migration assay, AO/EB and Hoechst 33342 staining assay, and Annexin V-FITC/PI double staining, n-BuOH (BU) fraction was identified as the most potent antitumor fraction. It exhibited potential anti-melanoma activity via the induction of apoptosis and vacuolization in B16-F10 cells. Transcriptomic and bioprocess-target network analysis revealed that BU fraction triggered apoptosis and vacuolization through regulating PI3K-AKT-FOXO, MDM2-p53 pathway and increasing the expression of Bcl-xl. In addition, quercetin might be served as one of the key anti-melanoma compounds in BU fraction through the similar mechanism. Although the anti-melanoma activity and mechanism of BU fraction have not been elucidated completely, this study effectively expands our understanding for the anti-melanoma activity of RKBC extract and provided the basis for the further functional food research and development using red kidney bean, as well as a new possibility for treating melanoma.3-Monochloropropanediol esters (3-MCPDEs) and glycidyl esters (GEs) with high toxicity have drawn global concerns due to their widespread occurrence in refined oils and oil-based foods. The effect mechanisms of organic chlorine compound lindane, inorganic chlorine compounds tetra-n-butylammonium chloride (TBAC) and sodium chloride (NaCl) on the formation of 3-MCPDEs and GEs were investigated in model oils and chemical models at 240 °C. Results showed that 3-MCPDEs contents increased with the addition of lindane and TBAC, whereas, surprisingly, GEs presented the same tendency as the results of 3-MCPDEs. This suggested that although chlorine compounds were not involved in the formation reaction of GEs, they could also promote GEs formation. Chemical model experiments confirmed that the presence of chlorine compounds led to the transformation of GEs to 3-MCPDEs and conversely 3-MCPDEs could also transform to GEs. The latter transformation rate from 3-MCPDEs to GEs was higher than the former, which might account for the fact that chlorine compounds promoted GEs formation. Additionally, it was also observed that solid NaCl did not induce the increase of 3-MCPDEs and GEs levels in chemical models, suggesting that the chlorine in NaCl, different from lindane and TBAC, was not available for 3-MCPDEs formation. The present findings give novel insights into the interactions between 3-MCPDEs and GEs formation mechanisms, which offer the theoretical basis for efficient and simultaneous inhibition of 3-MCPDEs and GEs.Aflatoxins are toxic secondary metabolites mainly produced by Aspergillus fungi, posing high carcinogenic potency in humans and animals. Dietary exposure to aflatoxins is a global problem in both developed and developing countries especially where there is poor regulation of their levels in food and feed. Thus, academics have been striving over the decades to develop effective strategies for degrading aflatoxins in food and feed. These strategies are technologically diverse and based on physical, chemical, or biological principles. This review summarizes the recent progress on novel aflatoxin degradation strategies including irradiation, cold plasma, ozone, electrolyzed oxidizing water, organic acids, natural plant extracts, microorganisms and enzymes. A clear understanding of the detoxification efficiency, mechanism of action, degradation products, application potential and current limitations of these methods is presented. In addition, the development and future perspective of nanozymes in aflatoxins degradation are introduced.The current study applied gas chromatography-mass spectrometry (GC-MS), liquid chromatography-mass spectrometry (LC-MS), and thermal desorption direct analysis in real-time mass spectrometry (TD-DART-MS) methods to the analysis of black pepper (Piper nigrum L.) samples from different countries. The black pepper powder samples were analyzed directly by TD-DART-MS without any extraction, but for GC-MS and LC-MS methods, a methanol extraction procedure was employed before the analysis. Various compounds, such as piperamides and terpenes, were detected. Partial least squares-discriminant analysis (PLS-DA) was used to classify black pepper samples based on their origins. Total ion mass spectrum (TMS) data profiles from GC-MS, LC-MS, and TD-DART-MS methods were constructed and evaluated for the performance of classification. A cubic-root data transformation was tested in the data preprocessing and found to be effective for improving the classification rates. The average classification rates of PLS-DA models with GC-MS-cubic-root-TMS, LC-MS-cubic-root-TMS, and DART-MS-cubic-root-TMS data representations were 94.1 ± 0.6%, 87.7 ± 0.6%, and 97.0 ± 0.3% respectively, for 100-time bootstrapped-Latin-partition cross-validation. This study presents for the first time the analysis of plant-based food materials by using TD-DART-MS, and it has been demonstrated as a simple and high-throughput method for classification studies.Microorganisms play an important role in the flavor formation of Chinese Baijiu. Mechanization is the way to develop Baijiu. Therefore, it is necessary to study the effects of mechanization on microbial community and flavor in Baijiu production. The microbial communities exhibited differences between two technologies with the fermentation, and the numbers of yeasts and bacteria in new mechanical technology were significantly higher than those in traditional technology at the peak of fermentation. Both metagenomic and metatranscriptomic analyses showed 5 core microorganisms in the fermentation, namely Saccharomyces cerevisiae, Rhizopus delemar, Pichia kudriavzevii, Lactobacillus helveticus, and Rhizopus oryzae. S. cerevisiae was generally regarded to be the most dominant yeast in Baijiu fermentation, but our metatranscriptomic data showed that P. kudriavzevii was more active than S. cerevisiae. These two analyses indicated that higher initiation abundance of S. cerevisiae and P. kudriavzevii and lower initiation abundance of R. delemar and R. oryzae were observed in traditional technology than in new technology, and that Lactobacillus displayed apparent advantages in traditional technology, whereas Lactobacillus and yeast exhibited obvious advantages in new technology at the end of fermentation. In addition to S. cerevisiae, other microorganisms including non-saccharomyces yeasts, molds, and bacteria were involved in higher alcohol formation. This work provides insight into the microbial dynamics and higher alcohol formation, as well as an efficient strategy for process improvement in Baijiu fermentation.Edible bird's nest (EBN) is built by seven species of Aerodramus and Collocalia (Apodidae), using salivary gland secretion mixed with feathers or grass during the breeding. Its rich nutritional values such as anti-aging activity, immunomodulatory and antioxidant activity make consumers flock to it. Consumers' pursuit, on the one hand, aroused the arrogance of counterfeiters, which eventually leads to food safety problems. On the other hand, it promotes the in-depth studies of EBN in all aspects, such as compositions, biological activities, authenticity identification, quality control, and so on. This paper presented the origins and classifications of EBN and the current situation of EBN industry in detail; reviewed the nutritional compositions, pharmacological actions, identification, inspection and content determination of EBN comprehensively; and prospected the future research directions to provide suggestions for the further study.Fried foods have potential adverse effects on health. However, the compounds produced during the process of frying in different vegetable oils are unknown. In this work, ultra performance liquid chromatography (UPLC), quadrupole time-of-flight mass spectrometry (Q-TOF MSMS) and chemical pattern recognition analysis was first conducted to analyze the changes in compounds in 8 different vegetable oils before and after thin-layer heating (without food) and to reveal the potential markers of oil used for deep-frying food. Then, these markers were validated in used frying oil. Our results of principal component analysis (PCA), partial least-squares discriminant analysis (PLS-DA) indicated that both thin-layer heating and deep-frying significantly change the compounds of vegetable oils. Thirty-six of the markers associated with thin-layer heating from the 8 different oils were identified in used frying oils and can be used as common markers of oil used for deep-frying. Additionally, 22 markers detected in individual vegetable oils provided unique markers of used frying oils. These markers can be used to distinguish used frying oil and have the potential to reveal the associated physiological harm.Sea urchin gonads are receiving increasing attention for their exclusive sensorial attributes. However, the sensory profile of this highly demanded gourmet product has not yet been well described, and it may potentially help enhancing the gonads' marketability and acceptability. The main goal of this study was to build a sensory profile of sea urchin (Paracentrotus lividus) gonads, to evaluate differences between sex, harvest location, as well as the impact of presentation on consumer acceptance. Sixty untrained panellists (regular consumers of seafood) were asked to evaluate eight samples of raw sea urchin gonads, divided by sex, harvest location and presentation (in a clear translucent glass bowl or inside a sea urchin test). The panellists evaluated overall liking and acceptance (Food Action Scale), followed by a Check-All-That-Apply (CATA) ballot with a list of 38 sensory attributes divided into four dimensions appearance (9), odour (8), texture (7) and taste (14), launched in Sense Gest. From a three-way ANOVA, no significant effect of sex, harvest location and presentation were identified for both liking and acceptance.
