Post-meal blood glucose measurements were taken in the fasting state and after 30, 60, 90, and 120 minutes. The phenolic, flavonoid, and antioxidant properties of ginger extract were measured. The intervention group's glucose levels demonstrated a noteworthy decline in the incremental area under the curve (p<0.0001) and a substantial decrease in the peak glucose concentration (p<0.0001). A polyphenolic content of 1385 mg gallic acid equivalent per liter, coupled with a flavonoid content of 335 mg quercetin equivalent per liter, characterized the extract, which exhibited an impressive superoxide radical inhibitory capacity of 4573%. This study highlighted ginger's positive influence on glucose regulation during acute situations, suggesting ginger extract as a compelling natural antioxidant source.
A patent repository concerning blockchain (BC) technology within the food supply chain (FSC) is methodically collected, elucidated, and analyzed through Latent Dirichlet Allocation (LDA) modeling, with the goal of extracting insights into the emerging trends in the sector. Patent databases were searched using PatSnap software, yielding a patent portfolio of 82 documents. An LDA analysis of latent topics in patents relating to blockchain technology (BC) and forestry supply chains (FSCs) reveals four primary categories: (A) BC-based tracing and tracking procedures in FSCs; (B) devices and methods enabling blockchain application in FSCs; (C) integration of BCs with other information and communication technologies in FSCs; and (D) BC-driven trading operations within FSCs. The second decade of the 21st century saw the first instance of patenting BC technology applications within forestry science certification systems (FSCs). In consequence, patent forward citations have been relatively low, and the family size highlights the fact that BCs in FSCs have not yet gained wide acceptance. The post-2019 period witnessed a substantial escalation in patent applications, indicating a predicted upsurge in the number of prospective users in the FSC industry. China, India, and the United States account for the highest number of patent filings.
The impacts of food waste on the economy, the environment, and society have propelled increased awareness of the problem over the past decade. Prior research has investigated consumer buying habits concerning sub-optimal and upcycled foods, yet the buying patterns related to acquiring surplus meals are understudied. This research, accordingly, performed consumer segmentation by employing a modular food-related lifestyle (MFRL) methodology and further examined consumer buying behavior towards leftover meals in canteens through the lens of the theory of reasoned action (TRA). A validated questionnaire was utilized to survey a conveniently selected group of 460 Danish canteen users. A k-means segmentation analysis identified four consumer lifestyle clusters based on food preferences: Conservative (28%), Adventurous (15%), Uninvolved (12%), and a substantial Eco-moderate (45%) segment. PLS-SEM structural equation modelling indicated that attitudes and subjective norms had a substantial and significant impact on the intention to buy surplus meals, leading to variations in buying behavior. The environmental objective knowledge substantially impacted environmental concerns, which subsequently affected attitudes and behavioral intent. Although environmental understanding of food waste existed, it did not substantively affect views on surplus meals. this website Surplus food purchasing behavior was more pronounced among male consumers who held higher educational attainment, displayed higher food responsibility, exhibited lower food involvement, and scored highly on convenience. These findings provide valuable insights for policymakers, marketers, business professionals, and practitioners, enabling them to promote surplus meals in canteens and similar locations.
The cold-chain aquatic products quality and safety issues, which resulted in an outbreak in 2020 in China, ignited public panic and ultimately caused a major crisis in the country's aquatic industry. Utilizing topic clustering and emotion analysis, this research delves into online commentary on Sina Weibo, identifying key characteristics of public opinion regarding the administration's handling of imported food safety crises, ultimately providing practical guidance for future management. Based on the findings, the public's response to both the imported food safety incident and the risk of viral infection encompassed four key characteristics: a noteworthy prevalence of negative sentiment; an extensive demand for information; a concern for the entirety of the imported food industry; and diverse reactions to control policies. In response to online public sentiment regarding imported food safety crises, the following strategies are proposed to enhance crisis management: The government should pay close attention to trends in online public opinion; concentrate on understanding the core concerns and emotional expressions of the public; conduct a thorough risk assessment of imported food, implementing specific classification and management protocols for food safety incidents; establish a comprehensive imported food traceability system; develop a dedicated recall mechanism for imported food safety incidents; and reinforce cooperation between government agencies and media, bolstering public trust in policies.
The widespread application of pesticides and the resulting pesticide residue contamination in agricultural products are a cause for growing health concerns worldwide. 2021 witnessed a monitoring program for pesticide residues, targeting 200 specimens of green leafy vegetables, including 80 dill, 80 rocket, and 40 parsley, purchased from greengrocer shops, markets, and bazaars within the Corum Province of Turkey. A rapid, economical, and robust QuEChERS sample preparation method was employed to analyze 363 pesticides in green leafy vegetables, followed by liquid chromatography-mass spectrometry (LC-MS/MS) for 311 residues and gas chromatography-mass spectrometry (GC-MS/MS) for 52 residues. Internal validation of the method was performed at two fortification levels, yielding satisfactory recoveries and precision for all detected residues. 35% of the samples contained no quantifiable residues, contrasting with the discovery of 43 residues belonging to 24 different chemical classes in 130 green leafy vegetables. Rocket, dill, and parsley represent a gradient of occurrence frequency among the green leafy vegetables, with rocket being the most frequent. Residue levels in 46% of green leafy vegetables exceeded the permissible limits set by the European Union (EU MRLs). In dill, pendimethalin was the most prevalent pesticide, exceeding expected levels by 225%, while rocket exhibited a diuron concentration 387% above normal, and parsley displayed the highest pymetrozine concentration, 525% above the average.
Following the COVID-19 pandemic and escalating food prices, alternative food sourcing methods gained widespread acceptance. The present study, on urban foraging in the U.S., explores the determinants of food foraging behavior, examining the distinct patterns of discarding food or consuming all available items, specifically in garden and non-garden settings. For sustainable foraging practices to thrive, it is essential to leave some food behind, facilitating the regeneration of plants and ecosystems, and ensuring equitable access for foraging communities. this website The online consumer survey provided data that was analyzed using SmartPLS 4, enabling partial least squares structural equation modeling (PLS-SEM). For intricate exploratory studies, PLS-SEM is exceptionally appropriate, as it does not necessitate distributional presumptions. Analysis reveals that perspectives on nature and nourishment strongly correlate with viewpoints on urban foraging. The significant obstacles inherent in food foraging and the profound benefits it provides to people and the Earth are the critical determinants in deciding whether to engage in foraging practices, across diverse locations. Stakeholders in municipal management, landscape design, and horticulture, as well as other parties responsible for food-foraging landscapes, benefit from the insights presented in these findings.
The antioxidant activities of seven polysaccharide degradation products (GLPs) originating from Gracilaria lemaneiformis, each differing in molecular weight (Mw), were compared. The respective molecular weights of GLP1, GLP2, GLP3, GLP4, GLP5, GLP6, and GLP7 were found to be 106 kDa, 496 kDa, 105 kDa, 614 kDa, 506 kDa, 371 kDa, and 242 kDa. The experimental results highlight the superior radical-scavenging activity of GLP2, with a molecular weight of 496 kDa, towards hydroxyl, DPPH, and ABTS radicals, coupled with the highest reducing power observed. The antioxidant activity of GLPs, characterized by a molecular weight (Mw) below 496 kDa, augmented in tandem with increasing Mw; however, beyond 106 kDa, this activity exhibited a decline. this website The ability of GLPs to capture Fe2+ ions increased with a reduction in the polysaccharide's molecular weight, a phenomenon that is related to the greater accessibility of the active groups (-OSO3- and -COOH), and a decrease in steric impediments in the Fe2+ binding event. The influence of GLP1, GLP3, GLP5, and GLP7 on calcium oxalate (CaOx) crystal growth kinetics was assessed via XRD, FT-IR spectroscopy, zeta potential, and thermogravimetric analyses. Calcium oxalate dihydrate (COD) formation was encouraged, and calcium oxalate monohydrate (COM) growth was suppressed by four varieties of GLPs, with varying degrees of efficacy. A decline in the molecular weight of GLPs was accompanied by an increase in the percentage of COD. Crystal surface Zeta potential's absolute magnitude was augmented by GLPs, leading to a decrease in crystal aggregation. Cell studies on HK-2 cells exposed to CaOx crystals indicated that the toxicity was inversely correlated with the GLP-regulation. Specifically, GLP7, the protein with the smallest molecular weight, exhibited the strongest protective effect, which was mirrored by high SOD activity, lower ROS and MDA levels, reduced OPN expression, and a decreased incidence of cell necrosis.
