Physicochemical and Thermal Evaluation of a Mixed-Mode Greenhouse Solar Dryer for Guava (Psidium guajava L.). [PDF]
J Food SciABSTRACT The present study aimed to evaluate the quality and nutritional properties of guava slices dried in a greenhouse solar dryer (operated under mixed and direct modes) and an electric stove at 50°C. The results showed that mixed‐mode solar drying resulted in greater retention of vitamin C (112.60 mg/100 g), carotenoids (0.37 mg/g), and ...

Wet and dry extremes reduce arthropod biomass independently of leaf phenology in the wet tropics. [PDF]
Glob Chang Biol, 2023 Although two‐thirds of terrestrial vertebrates consume insects and spiders, how changing rainfall regimes will affect arthropods remains poorly understood. Using spatiotemporal variation in tropical montane climate as a natural experiment, we show arthropod biomass maxima at intermediate rainfall as 3 months of both wet and dry extremes reduced ...

MODELACION DEL SECADO DE COIGUE BASADA EN EL COEFICIENTE GLOBAL DE SECADO
Maderas. Ciencia y tecnología, 2001 El objetivo principal del presente trabajo fue estudiar la cinetica del secado convencional a baja temperatura del coigue ( Nothofagus dombeyi) por medio de una modelacion simple. El modelo matematico utilizado consiste en un sistema de ecuaciones diferenciales parciales de primer orden resultante del balance de masa y entalpia en cada subsistema (

Spatially resolved detection of small molecules from press‐dried plant tissue using MALDI imaging
Applications in Plant Sciences, Volume 11, Issue 5, September-October 2023., 2023 Abstract Premise Matrix‐assisted laser desorption/ionization mass spectrometry imaging (MALDI‐MSI) is a chemical imaging method that can visualize spatial distributions of particular molecules. Plant tissue imaging has so far mostly used cryosectioning, which can be impractical for the preparation of large‐area imaging samples, such as full flower ...

Energy analysis of drying basil (Ocimum basilicum) leaves in an active greenhouse solar dryer
Journal of Food Process Engineering, Volume 46, Issue 3, March 2023., 2023 Abstract The need for better utilization of solar greenhouses during summer in the hot climate conditions of Mexico led to the development of the concept of active greenhouse solar dryers. The objective of this research was energy analysis of an active greenhouse solar dryer for basil leaves drying.
