Recent epidemiological studies have explored the association between organic food consumption and the risk of obesity, but the results remain controversial. A systematic review and meta-analysis were conducted to determine the association between organic food consumption and the risk of obesity. Rigorous methods for a comprehensive search were employed to search for literature in PubMed/MEDLINE, Web of Science, and Embase for relevant articles published until 30 November 2021. Pooled odds ratio (OR) with 95% confidence intervals (Cis) were calculated using a DerSimonian and Laird random-effects model to understand the risk of obesity based on exposure to organic food. Four studies, comprising 104,488 healthy subjects and 39,425 adults who consumed organic food, reported 1625 incident cases of obesity. Compared with the unexposed group, organic food consumption was associated with a lower probability of obesity (OR: 0.89, 95% CI: 0.80-0.97, < 0.001). Subgroup analysis showed that this association was higher in the cohort (OR: 0.78, 95% CI: 0.63-0.92) than cross-sectional studies (OR: 0.95, 95% CI: 0.91-1.00), respectively. Overall, organic food consumption had a modest reduction (11%) in the risk of obesity and can be an appropriate strategy to prevent obesity.

Selenium-enriched probiotics have attracted much attention due to the physiological activities of both probiotics and selenium (organic selenium). In this study, we investigated the mitigating effect of selenium-enriched GG (LGG@Se) and its pathway on alcohol-induced liver injury (ALI) in mice. The results showed that LGG@Se was superior to LGG and sodium selenite in alleviating ALI.

Protein concentrate (PC) is a potential solution to address the global protein shortage, with Indonesian shortfin eel being a suitable raw material. This research investigates the impact of ultrasound pretreatment and extraction parameters on the nutritional quality of eel protein concentrate (EPC). The study involved ultrasonic pretreatment at different times and power, and solvent extraction with different solvents, temperature, and solvent-solid-feed-ratio (SSFR).

Aiming to enable online freshness-monitoring of meat within modified-atmosphere package, we developed a ratiometric array that was fluorescently responsive to volatile organic compounds-ammonia (NH) released by protein decaying. The array was consisted of two 3 mm × 6 mm rectangles precisely and uniformly printed with fluorescein isothiocyanate (FITC) as indicator and rhodamine B (RhB) as internal reference on the filter-paper, respectively. The fluorescence intensity of the array area was calibrated according to Green/Red ratio of the digitalized pixels extracted from images facilitated by a smartphone.

Biomineralization of enzymes inside rigid metal-organic frameworks (MOFs) is appealing due to its biocompatibility and simplicity. However, this strategy has hitherto been limited to microporous MOFs, leading to low apparent enzymatic activity. In this study, polysaccharide sodium alginate is introduced during the biomineralization of enzymes in zeolitic imidazolate frameworks (ZIFs) to competitively coordinate with metal ions, which endows the encapsulated enzyme with a 7-fold higher activity than that in microporous ZIFs.
