Reliable biotransfer factor (BTF) data are critical for animal-feed studies in human risk assessment. A wide range of BTF values have been reported (0.0015–0.83 d/kg), expressed as the ratio of total arsenic (tAs) concentration (µg/kg) in chicken to daily intake rate (µg/d) of tAs in feed (tAs/tAs). Data on inorganic As (iAs) for chicken meat and tAs concentrations for feed were obtained from our related study. Using the linear regression technique developed in this study, we estimated the BTF as 0.016 d/kg, as iAs/tAs (R 2 > 0.7702) and 0.55 d/kg as tAs/tAs (R 2 = 0.9743) for whole chicken meat. From a mass-balance perspective, we suggest that tAs be used as the denominator for the BTF unit. To illustrate our feed-risk assessment method, we analyzed commercial feeds for tAs concentration (n = 79). Consumption data for the general population (n = 2479) were obtained from a Taiwanese total diet study. Bivariate Monte Carlo simulations (n = 10,000) showed that the 95th percentile (P95) of estimated daily intake (EDI) was 0.002 µg/kg body weight (bw)/d as iAs ( © 2023 Taylor & Francis Group, LLC.

This research aims to evaluate the sensory description of arabica and canephora coffee by consumers, identify how and canephora coffee by consumers, and identify how physicochemical variables affect sensory perception. Three Brazilian coffees (two arabica and one canephora) were determined sensorial attributes by the Check-All-That-Apply (CATA) method with 190 consumers in a home test, and physicochemical (pH and caffeine content) and chromatic parameters. The results showed that visual perception, brightness, and orange coloration are the main means used to distinguish arabica coffee from commercial coffee. In addition, the perception of sweeter aromas (toffee, vanilla, and caramel spread), chocolate with greater intensity, and the less intense bitterness taste were important typicality markers to differentiate arabica coffee (cv. Typica). The analysis of the correlations between caffeine and bitterness, sweetness, and acidity demonstrates the consumer's ability to perceive basic tastes in the different coffee samples. The chromatic parameters obtained significant correlations with visual, olfactory, and gustatory attributes. This study indicated the consumer's ability to establish typical traits for Arabica coffee depending on the place of cultivation. In addition, consumers perceive the influence of physicochemical variables on sensory attributes, highlighting the need for quality in an increasingly demanding and globalized market. © 2023

Considering the importance of polyphenol intake in reducing the risk of non-communicable chronic diseases, it is essential to encourage populations around the world, especially in Brazil, to consume foods that increase the presence of these compounds in their diet. This study aimed to identify the foods with the highest total polyphenol content and classes consumed by the Brazilian population, as well as their degree of processing. The study was conducted using secondary data collected from the 2017–2018 Household Budget Survey, which included the actual per capita food consumption of the Brazilian population and the usual portion size of foods. The investigation focused on 41 food items with the highest consumption frequency. Estimates of the total polyphenol (TP) content and classes in the foods were obtained from the Phenol-Explorer database, and the degree of food processing was classified according to the NOVA classification. Based on the ranking of the main foods consumed by Brazilians with the highest total polyphenol (TP) content, coffee (169.527 mg) and beans (38.422 mg) stood out for the average per capita consumption, while corn and its preparations (187.250 mg) and oranges (72.683 mg) stood out when analyzing the portion consumed in a single occasion. Regarding the polyphenol classes, the foods with the highest amounts consumed by Brazilians predominantly contained phenolic acids. Concerning the degree of processing, based on the NOVA classification, 76 % of the foods with the highest polyphenol levels belonged to the in natura and minimally processed food category, while 15 % corresponded to ultra-processed foods. It is essential to encourage the consumption of traditional foods in the Brazilian diet, as these are important sources of polyphenols. It is worth emphasizing the relevance of in natura and minimally processed foods as the basis of the Brazilian diet, mainly concerning the total polyphenol contents. © 2024 Elsevier B.V.

Electrospinning encapsulation is a highly viable method to protect bioactive compounds and prevent their degradation. Hence, this study produced ultrafine fibers based on yellow and white sweet potato starches and a red onion skin extract (ROSE;0, 3, 6, and 9%, w/w) using electrospinning. The fibers were evaluated for morphology, thermogravimetric properties, antioxidant, in vitro release simulation, thermal resistance (100 and 180 ºC), and wettability. The fibers with ROSE presented 251–611 nm diameters, 67–78% encapsulation efficiency, and 51.6–95.4 and 13.4–99.4% thermal resistance (100 and 180 ºC, respectively);apigenin presented the highest thermal protection. The phenolic compounds showed low release using 10% ethanol and greater release with 50% ethanol. The fibers with 9% ROSE showed 2,2'-azino-bis(3-ethylbenzothiazoline) 6-sulfonic acid radical inhibition above 92%. Our findings revealed that the potential application of the fibers with ROSE depends on the conditions and purpose of the food packaging or food matrix. © 2022, The Authors. All rights reserved.

Diets rich in antioxidants from foods are linked to a lower risk of developing and progressing of noncommunicable diseases. Unlike estimates of population antioxidant intake, this study aimed to estimate the total antioxidant capacity (TAC) of meals suggested in the Dietary Guidelines for the Brazilian population (DGBP) (2014), as well as identify the main contributing foods. The research was quantitative and descriptive, based on the analysis of secondary data from photographic records of the suggested meals (breakfast, lunch, and dinner) in the DGBP. The foods, their preparation methods, and portion sizes were identified. food TAC was mainly estimated using the Ferric-Reducing Ability Power (FRAP) method, based on Carlsen et al. (2010). Subsequently, the TAC of the meals, the percentage contribution of each food item, and the TAC adjusted to 250 kcal were estimated. The average TAC found was 3.01 ± 1.35 mmol in breakfast suggestions, 1.93 ± 0.84 mmol in lunch suggestions, and 2.49 ± 3.34 mmol in dinner suggestions, with no significant differences when comparing the TAC results among the three meals (p = 0.608). However, coffee was identified as the main contributor in breakfast suggestions, while beans stood out as the main contributor in lunch and dinner suggestions. Therefore, the foods that most prominently contributed to the TAC of the meals suggested by DGBP were those that, in addition to being part of the national food culture, are classified as natural or minimally processed. These findings reinforce the public health value of promoting diets based on natural or minimally processed foods, highlighting their importance in providing bioactive compounds which may help prevent chronic diseases and improve population health. © 2025 Elsevier B.V.

This paper analyses how collaborative practices influence sustainability initiatives and the relational rents of Brazilian coffee companies supplying global supply chains (GSC)s. Multi-case study data was collected via interviews and documentary analysis and examined using the relational view theoretical lens. The results indicate that collaborative practices lead to significant improvements within the supplier’s sustainability initiatives and consequently within their processes related to the exportation of goods. Thus this study suggests that collaborative practices generate important relational rents in GSCs (for example through relationship-specific assets) and are important facilitators of sustainability for emerging economy suppliers. © 2021 Taylor & Francis Group, LLC.

Over the past decades, proteomics has become increasingly important and a heavily discussed topic. The identification of intact proteins remains a major focus in this field. While most intact proteins are analyzed using high-resolution mass spectrometry, identifying them through low-resolution mass spectrometry continues to pose challenges. In our study, we investigated the capability of identifying various intact proteins using collision-induced dissociation (CID) and electron transfer without dissociation (ETnoD). Using myoglobin as our test protein, stable product ions were generated with CID, and the identities of the product ions were identified with ETnoD. ETnoD uses a short activation time (AcT, 5 ms) to create sequential charge-reduced precursor ion (CRI). The charges of the fragments and their sequences were determined with corresponding CRI. The product ions can be selected for subsequent CID (termed CIDn) combined with ETnoD for further sequence identification and validation. We refer to this method as CIDn/ETnoD. The use of a multistage CID activation (CIDn) and ETnoD protocol has been applied to several intact proteins to obtain multiple sequence identifications. © 2024 The Authors.

作者： dos Santos, Pedro Henrique Dutra Weis, Cláudia Moreira Santa Catharina Zanette, Cristina Maria Bertan, Larissa Canhadas Tormen, Luciano Bainy, Eduarda Molardi Food Science and Technology Graduate Program Federal University of Fronteira Sul (UFFS) BR 158 Parana Laranjeiras do Sul 85319-899 Brazil Food Engineering Department Midwestern State University (Unicentro) Parana Guarapuava 85040-167 Brazil

Pink pepper (Schinus terebinthifolius) is a native plant from Brazil, and its fruits contain bioactive compounds with antioxidant properties. Meat products are naturally susceptible to lipid oxidation due to the characteristics of the raw material. Consequently, natural alternatives that can replace synthetic additives in these products may be an alternative. This study aimed to produce an artisanal smoked pork sausage with the addition of pink pepper and evaluate the product's antioxidant properties. The dehydrated pink pepper was characterized for phenolic compounds, chemical composition via GC-MS, and antioxidant activity (DPPH and FRAP assays). Five formulations of smoked pork sausage were prepared: a control, three with pink pepper powder (0.5 %, 1.0 %, and 1.5 %), and a formulation with BHT (0.01 %). The sausages were analyzed for pH, titratable acidity, instrumental color, and thiobarbituric acid reactive substances (TBARS) assay at the beginning of the manufacture and every 5 days over 30 days of storage at 25 ºC. Due to the product's artisanal nature, the analysis period was shortened. The formulation with the best results was characterized by proximate, microbiological, and sensory analyses. The pink pepper demonstrated promising antioxidant capacity in the samples evaluated. The pH remained stable at around 5.4, while titratable acidity varied across the formulations, with values increasing over the storage. The addition of 0.5 % pink pepper effectively prevented lipid oxidation compared to the control and BHT formulation. This formulation had high protein and low lipid contents. It also presented good sensory acceptance and purchase intention. Pink pepper can be a viable natural alternative to synthetic antioxidants, especially for use in meat products and artisanal smoked sausages. © 2025 Elsevier B.V.

Abstract: Agastache rugosa contains phenolic compounds and flavonoids, and has been extensively used as a traditional herbal medicine. The major components in Agastache rugosa are rosmarinic acid, tilianin, and acacetin, for which several analytical techniques have been reported. However, these substances have yet to be simultaneously quantified in human plasma. In this study, we aimed to simultaneously determine the three active components of Agastacherugosa in human plasma by developing a reliable quantitative analytical method using ultra-high-performance liquid chromatography–tandem mass spectrometry (UHPLC-MS/MS). Chromatographic separation of the plasma samples was achieved using an ACQUITY UPLC® BEH C18 column with a gradient mobile phase of water and acetonitrile containing 0.1% formic acid. Mass spectrometric detection was performed using a triple quadrupole tandem mass spectrometer in negative electrospray ionization (ESI−) and multiple reaction monitoring (MRM) modes. The developed quantitative method was validated for the three active components. All three analytes exhibited a linear response over the ranges of 0.5–50 ng/mL for rosmarinic acid, 0.1–20 ng/mL for acacetin, and 0.5–20 ng/mL for tilianin with a weighting factor of 1/x (where x is the concentration). At three quality control (QC) concentration levels (low, medium, and high), including the lower limit of quantitation (LLOQ), acceptable accuracy (±15%) was achieved in the intra- and interday validations. The concentration of rosmarinic acid was highest in plasma. Tilianin and acacetin appeared and were eliminated earlier in the plasma than rosmarinic acid. This study provides a successfully validated method that can be used in further clinical applications of Agastache rugosa extracts. © 2023, The Authors. All rights reserved.
