g., humic acid, phenol, pyridine or sorbate, has a minimal effect on the PMS mediated oxidation processes, highlighting the strong application potential of PMS in water treatment.For half a century, the dominant paradigm in psychotherapy research has been to develop syndrome-specific treatment protocols for hypothesized but unproved latent disease entities, as defined by psychiatric nosological systems. While this approach provided a common language for mental health problems, it failed to achieve its ultimate goal of conceptual and treatment utility. Process-based therapy (PBT) offers an alternative approach to understanding and treating psychological problems, and promoting human prosperity. PBT targets empirically established biopsychosocial processes of change that researchers have shown are functionally important to long terms goals and outcomes. By building on concepts of known clinical utility, and organizing them into coherent theoretical models, an idiographic, functional-analytic approach to diagnosis is within our grasp. We argue that a multi-dimensional, multi-level extended evolutionary meta-model (EEMM) provides consilience and a common language for process-based diagnosis. The EEMM applies the evolutionary concepts of context-appropriate variation, selection, and retention to key biopsychosocial dimensions and levels related to human suffering, problems, and positive functioning. The EEMM is a meta-model of diagnostic and intervention approaches that can accommodate any set of evidence-based change processes, regardless of the specific therapy orientation. In a preliminary way, it offers an idiographic, functional analytic, and clinically useful alternative to contemporary psychiatric nosological systems.The effects of preharvest treatments with 0.1 mM methyl jasmonate (MeJA) and 0.5 mM salicylic acid (SA) on quality parameters of lemon fruit and their relationship with antioxidant systems, gene expression and bioactive compounds at harvest and during cold storage were evaluated. Results showed that total antioxidant activity, total phenolic content and the major individual phenolics (hesperidin and eriocitrin) were always higher in treated fruit than in controls. The activity of the antioxidant enzymes catalase, peroxidase and ascorbate peroxidase was also increased at harvest by SA and MeJA treatments, especially the last enzyme, for which the expression of its codifying gene was also enhanced. In addition, treated fruit had lower weight and firmness losses, respiration rate and production of ethylene than controls. Moreover, sugars and organic acids were maintained at higher concentration in flavedo and juice as a consequence of preharvest SA and MeJA treatments, showing an effect on maintaining fruit quality properties.In order to avoid the occurrence of false positives and false negatives caused by conventional enzyme-linked immunosorbent assay (ELISA), we established a novel indirect competitive MOF-linked immunosorbent assay (MOFLISA) method for the high throughput and high sensitive detection of aflatoxin B1. This method replaces the natural enzyme with functional MOFs to catalyze a chromogenic system. As a result, the limit of detection (LOD) of the MOFLISA method was 0.009 ng·mL-1 with a linear working range from 0.01 to 20 ng·mL-1. The developed MOFLISA method for AFB1 has a 20-fold improved LOD value compared with the conventional ELISA. The recoveries and relative standard deviations (RSD) ranged from 86.41 to 99.74% and 2.38-9.04%, respectively. The results demonstrate that the recovery rate and accuracy of this detection method is better than that of conventional ELISA, reducing risks offalsepositive andfalsenegativeresults.A liquid chromatography method coupling diode-array and fluorescence detectors (DAD and FLD, respectively) has been developed for the simultaneous quantification of 32 phenolic compounds (PCs) in winemaking products. With the combination of both detectors it was possible to determine phenolic acids, flavanols, flavonols, stilbenes and other PCs in the matrices under study. An excitation wavelength of 290 nm was selected and three different emission wavelengths (315, 360 and 400 nm) were recorded. The method provided detection and quantification limits (LODs and LOQs) within the ranges of 0.01-1.46 mg/L and 0.03-4.9 mg/L, respectively. The LODs and LOQs using FLD for flavanols, stilbenes and phenyl ethanol analogues were improved between 65 and 1000% as compared with DAD. The combination of DAD with FLD increased both, sensitivity and the ability to reduce interfering signals. The developed method was applied for the characterization of PCs of wines, bunch stems and grape canes.Peptides derived from whole proteins in beef tenderloin (M. psoas major, PM) and striploin (M. longissimus lumborum, LL) associated with meat quality and muscle fiber composition were identified and quantified during 21 days of aging. Peptide quantification revealed 40-43 proteins to be significantly degraded during all aging time, and these were mostly sarcoplasmic proteins. Cooking loss of both muscles was not changed by aging (P > 0.05), whereas Warner-Bratzler shear force and meat color were affected by aging. Sensory tenderness increased in PM after 14 days of aging (P less then 0.05). PM had a higher type I fiber content, whereas LL had a higher type IIX fiber content (P less then 0.05), resulting in differences in proteolysis during all aging periods tested. These findings improve our understanding of different biochemical and physicochemical changes in aged meat according to the muscle type.The aim of the present study was to determine the impact of Saskatoon powder addition on phytochemical parameters, biological activity, and nutritional value of wheat bread. Supplementation increased phenolics content up to 72% in the bread with 6% powder content. This increase was reflected in the improved antioxidative properties of breads, especially after their supplementation with the microencapsulated additives (an increase by 93% in the bread enriched with 6% of powder covered with maltodextrin). The in vitro digestion released the antioxidative compounds, leading to higher bioaccessibility of the breads enriched with the microencapsulated powders. The highest inhibition of activities of cyclooxygenase 1 and -2, as well as amylase and glucosidase was recorded for the breads enriched with the additive microencapsulated with maltodextrin and inulin. Thus, Saskatoon berry powders, especially the microencapsulated ones, may be used as functional components in designing innovative bakery products.Plant-based protein foods are increasingly common, but data on their nutritional protein quality are scarce. This study evaluated it for seitan (wheat-based food), tofu (soya-based food), soya milk, and a pea emulsion. The true ileal digestibility (TID) of their amino acids was determined in minipigs, to calculate the digestible indispensable amino acid score (DIAAS). The TID of the proteins was high and not significantly different between the foods tested 97% for seitan, 95% for tofu, 92% for soya milk and 94% for pea emulsion. There were only minor differences in individual amino acid TIDs. DIAAS ranking was thus essentially driven by the amino acid composition of the food soya-based food > pea emulsion > seitan. Nevertheless, the lower TID of sulphur-containing amino acids in tofu than in soya milk induced a significant decrease in DIAAS (from 117% to 97%), highlighting the importance of the matrix effect on nutritional protein quality.The umami-enhancing effect of typical kokumi-active γ-glutamyl peptides was verified by sensory evaluation. To investigate the umami-enhancing molecular mechanism of the peptide on monosodium glutamate (MSG) taste, a novel hypothetical receptor, taste type 1 receptor 3 (T1R3)-MSG complex, was constructed. These peptides demonstrated strong interactions with T1R3-MSG. Moreover, four amino acid residues, Glu-301, Ala-302, Thr-305, and Ser-306, were critical in ligand-receptor interactions. In detail, γ-Glu-γ-Glu-Val (γ-E-γ-EV) readily interacts with T1R3 through hydrogen bonds and hydrophobic interactions. While γ-E-γ-EV did not bind to MSG, γ-Glu-Val (γ-EV) and γ-Glu-Leu (γ-EL) showed high binding affinity to MSG and interacted with T1R3 through hydrophobic bonds suggesting that the interactions between dipeptides and T1R3-MSG were weaker than tripeptides. These results demonstrated that kokumi-active γ-glutamyl peptides could enhance the umami taste of MSG, and exhibit synergistic effects in activating T1R3. This study provides a theoretical reference for interactions between the novel umami-enhancing substances and umami receptor.The purpose of this research was to study the effect of hot air drying, microwave vacuum drying and freeze drying combined with explosion puffing drying (HDEPD, MDEPD and FDEPD) on physicochemical properties, antioxidant activities and flavor characteristics of apples. The results showed that MDEPD and FDEPD products had better color and textural properties, exhibited a homogeneous porous structure. MDEPD and FDEPD better preserved scavenging abilities of DPPH, hydroxyl radical and FRAP, retained values of TFC and TPC. Aroma characteristics and taste properties of apples obviously changed with different drying methods, and drying qualities of products could be classified in terms of volatile compounds and taste profiles. Two principal components were able to describe 90.12% and 69.43% of the total volatile compound variance and total taste profile variance, respectively. Three main clusters of dried apples were identified, MDEPD and FDEPD can be used to enhance drying qualities of apple products.Potential improvements to the physical properties of brittle, self-assembled zein networks through microbial transglutaminase crosslinking were investigated. The formation of crosslinked heteropolymers was also explored with networks containing zein and either soy or pea protein isolates as supplemented lysine sources. The observed SDS-PAGE bands did not show any evidence of zein crosslinking. Soy and pea isolates underwent extensive crosslinking on their own, but heteropolymers were not observed in multiprotein networks with zein. Despite the lack of crosslinking observed, rheological and textural analysis revealed that the enzymatic treatment of zein produced a weaker, more brittle structure. With no significant changes in secondary structure, determined through FTIR, the observed behaviour was primarily attributed to glutamine deamidation by microbial transglutaminase in the absence of sufficient lysine through changes to the hydrophobicity of the protein such that non-covalent bonding within network was modified.UV-C treatment is a commonly known technique to inactivate microorganisms. The objective of this work was to investigate the impact of UV-C treatment of grape must on the sensory characteristics of the resulting wine and on the profile of volatile compounds of grape must and wine. Different UV-C doses were applied to Riesling must and compared with thermal pasteurization. The sensory off-flavor "ATA" and a content of 0.5 µg/L 2-aminoacetophenone were determined in the grape must and in the resulting wine after UV-C treatment with a high dose of 21 kJ/L. Sensory off-flavors did neither occur after thermal pasteurization nor after UV-C treatment with a dose of 2 kJ/L, which is sufficient for the inactivation of microorganisms. Minor changes in the volatiles' profiles of grape must and wine, involving e.g. terpenes and C13-norisoprenoids, occurred in musts treated with thermal pasteurization as well as with a UV-C dose of 2 kJ/L.
