Article Abstract
Indoor pollution has been a growing concern, especially about its potential effects on human health. Musty odors are a good indicator of indoor mold contamination and have been shown to be associated with numerous diseases, but their association with cognitive function in older adults is unclear. The study's data came from the Chinese Longitudinal Healthy Longevity Survey. The self-reported indoor musty odors were adopted as the independent variable. The cognitive impairment was included as the dependent variable using the Chinese version of the Mini-Mental State Examination. We employed logistic regression analyses to study the association between indoor musty odors and cognitive impairment. Additionally, stratified and interaction analyses were conducted to explore potential modifiers of this association. A total of 11,888 older adults (median age = 82.00 years) were included in this study. The study indicated that indoor musty odors were significantly associated with cognitive impairments (OR 1.40, 95% CI 1.25, 1.57). In the stratified and interaction analysis, there was no significant modification effect existed for the indoor musty odors and cognitive impairment in the study subgroups. And the associations were robust in the sensitivity analyses. These findings provide valuable insights into the potential health risks associated with indoor musty odors and cognitive impairment among older adults. It also suggests the importance of concerns about indoor environment on older adults' health, especially with regard to biological pollutants.

Background: Indoor air pollution has been recognized as a risk factor for mental health, particularly depression and anxiety symptoms. Indoor musty odors are considered a component of indoor air pollution. However, evidence on the associations between indoor musty odors and mental health among older adults is limited.

To comprehend the olfaction process at a microscopic level, further elucidation of its multiple stages was essential. The content of this study served as an initial step towards achieving this goal via the examination of the adsorption of geosmin molecules on polar bear and camel olfactory receptors. The tested odorant, which is a common volatile sesquiterpenoid produced by microorganisms, was responsible for degrading the quality of various beverages, foods, and drinking water due to its unpleasant "earthy/musty" off-flavor.

Despite advances in the operation of recirculating aquaculture systems (RAS), accumulation of earthy-muddy off-flavors in the fish remains a potential risk. Myxobacteria (Myxococcota) are reported to be among the most abundant geosmin synthase-harboring groups in RAS, but previous isolation attempts have been unsuccessful, limiting the knowledge of their role in off-flavor production. For the first time, we successfully isolated two geosmin-producing myxobacteria from RAS: AT3 and AT4.

The flavor characteristics, perception, and molecular mechanisms of eight menthol isomers were investigated by sensory analysis combined with computational simulations. The sensory analysis results show significant differences in the odor profiles of the different menthol isomers. Among them, L-menthol shows a pleasant, sweet, and mint-like odor with a distinct freshness and no off-flavors, whereas the remaining seven isomers were interspersed with negative odors (musty, herbal, or earthy aromas).
