The locals like to chew the seeds for their distinctive flavor “sweet water taste”. In this study, enzymatic hydrolysis, gel filtration chromatography, and reversed-phase high-performance liquid chromatography were used to extract, isolate and purify flavor peptides from the seed kernels of <i>Capparis masaikai</i> Lévl. Nano-LC−MS/MS was used to identify 219 peptides in total. Five new bitter peptides (HIGP, FHP, CFR, LYR and SFR) were screened by molecular docking. The results of molecular docking indicated that hydrogen bonds and hydrophobic bonds played essential roles in the binding of the five bitter peptides to T1R2-T1R3, T2R1 and T2R34. Phe75 and Glu74 on T2R1 and Arg373 on T1R2-T1R3 might be the critical amino acids in the binding site. The taste properties of the synthesized peptides were confirmed by sensory evaluation, and it was found that five peptides exhibited a specific sweetness inhibition. Not only do these results shed light on the interaction between flavor peptides and taste receptors, but they also help explain the “sweet water taste” of the seed kernels of <i>Capparis masaikai</i> Lévl. The results of this study help to explore the potential of flavor peptides in an enzymatic hydrolysate of <i>Capparis masaikai</i> Lévl seed kernels and broaden the diversity of flavor sources for the “sweet water taste”.</p></div>","PeriodicalId":549,"journal":{"name":"European Food Research and Technology","volume":"250 9","pages":"2445 - 2459"},"PeriodicalIF":3.0,"publicationDate":"2024-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140887925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The samples (n = 30) included broths of different origins, including laboratory-prepared broths and broths prepared by professional cooks from Czech school canteens. The broths were evaluated as potential sources of essential elements in relation to their reference daily intake, as well as their potential toxicity risk in relation to Cd and Pb. Although significant variability was observed in the contents of the investigated elements, the results generally contradicted the popular narrative that broths are a good source of Ca, Cu, Fe, and Mg, as their contents did not achieve even 5% of the recommended daily intake. The amount of Ca in the broths was minimal even compared to the amount in tap water.

Compared to MS, HPS emulsions had smaller droplet size, and HPS emulsions from pea and lentil were more viscous than soy and faba bean. The HPS films were lighter and more green and yellow in colour compared to MS films. HPS also improved the mechanical properties of the films resulting in higher tensile and puncture strength for pea and soy and higher tensile elongation and puncture deformation for most of the legumes. There was an inverse relationship between legumes where overall stronger and less flexible films were prepared from pea and soy, and vice versa from lentil and faba bean. HPS resulted in pea and soy films with less swelling ability and higher water vapour permeability (WVP), indicative of a poorer moisture barrier when homogenized this way. The MS films had similar WVP regardless of legume type, while under HPS it was the lowest for faba bean and highest for soy, despite the high swelling ability for both legumes. In short, pea, lentil, and faba bean protein isolates prepared emulsion films with good mechanical properties and water resistance, suggesting the potential to replace soy as edible packaging materials.

A bibliometric and systematic analysis of the literature was carried out. First, for the quantitative analysis of the scientific production, the bibliometric study was conducted, using the WoS database for data collection and the VosViewer and Bibliometrix applications to create the network maps. Second, once the literature had been examined quantitatively, content analysis was undertaken using the PRISMA methodology. The results show, among other aspects, the uneven distribution of the examined scientific production from 1996 to 2022, that computer vision, data aggregation, life cycle assessment, precision viticulture, extreme learning machine and collaborative platforms are the major current keywords and the predominance of Spain and Italy in terms of scientific production in the field. There are various justifications which support the originality of this study. First, it contributes to the understanding of academic literature and the identification of the most recent trends in the study of automation in the wine industry. Second, to the best of our knowledge, no prior bibliometric studies have considered this topic.
