What are the factors that affect the moisture content during the study of stability?5 answersThe factors influencing moisture content stability during stability studies include the environment's relative humidity (RH), water content, temperature, and the moisture history of the samples. Excipients in tablet formulations can have RH-dependent or RH-independent moisture content, impacting drug stability. In crude oil emulsions, water content and temperature play crucial roles in emulsion stability, with higher water concentrations leading to decreased stability. For soil shear strength, the water content significantly affects stability, especially in clayey soils, where shear strength may not decrease as expected with increased water content. In high-fill compacted loess embankments, water content influences density, dry density, cohesion, and friction angle, affecting embankment stability, which can be improved with geogrid layers.
What is the moisture content of african palm oil/?5 answersThe moisture content of African palm oil, specifically crude palm oil (CPO), was determined using Fourier transform infrared (FTIR) spectroscopy. The study utilized a calibration set with varying moisture ratios and employed a partial least squares (PLS) regression technique to develop a rapid and accurate method for moisture content determination in CPO samples. The accuracy of this FTIR spectroscopic method was comparable to traditional methods like the American Oil Chemists' Society's vacuum oven method and the International Union of Pure and Applied Chemistry's distillation method. The results showed that the moisture content of CPO can be analyzed swiftly with high precision, making it a reliable technique for moisture determination in palm oil products.
What are ideal storage conditions for dried fruits?5 answersThe ideal storage conditions for dried fruits involve a combination of factors to maintain quality. Research indicates that storing dried fruits in modified atmospheres (MAPs) with low temperatures is beneficial for preserving color, nutrients, and overall quality. Additionally, the drying process plays a crucial role in determining the quality of dried fruits, with factors like temperature, air flow velocity, and duration affecting organoleptic characteristics and nutrient composition. Solar drying has also been highlighted as a feasible technique for preserving fruits, improving physicochemical qualities, reducing microbial load, and extending shelf life. Moreover, a specific storage method for dried fruits involves steps like soaking in citric acid solution, air-drying, vacuum drying, and adding a drying agent to enhance efficiency and quality. Overall, combining MAPs with low temperatures, optimal drying parameters, and solar drying techniques can provide ideal storage conditions for dried fruits.
What is the effect of moisture on cacao quality and shelf life?3 answersMoisture damage to cacao beans alters their volatile chemical signature, which can be tracked quantitatively over time. This change in chemical signature can be detected by sampling the headspace vapor above the beans and analyzing it using gas chromatography combined with mass spectrometry. Hot-water treatment at 50-55℃ for 6-8 minutes can control decay and reduce respiration intensity in 'dongzao' fruit, leading to better quality and longer shelf life. Partially drying cacao beans in a stream of carbon dioxide or nitrogen and storing them at 25-28°C can maintain their viability for up to 60 days, compared to only 45 days when dried in air. A moisture content of about 50% is optimal for reducing deterioration and promoting germination. Moisture migration in multicomponent food products, such as liqueur-filled chocolates and bakery products, can cause textural changes and spoilage. The use of barrier layers, particularly hydrophobic materials like fats and waxes, can help prevent moisture migration and maintain product quality.
What is moisture content in fresh cacao?4 answersThe moisture content in fresh cacao varies depending on the specific conditions and processing methods. In one study, it was found that the ideal moisture content for quality dried cocoa beans is between 10% and 7% on a wet weight basis. Another study mentioned that during anaerobic incubation, the fresh weight of ripe cocoa seeds (without testae) increased considerably by water absorption, indicating a high moisture content. Additionally, a study on cacao bean fermentation mentioned that the moisture content of cacao beans influences the quality of cacao during fermentation. However, the specific moisture content of fresh cacao was not explicitly mentioned in any of the abstracts provided.
What is the relationship between rainfall and storage?5 answersRainfall and storage are closely related in several ways. One aspect is the use of rainfall for natural cooling in buildings, where rainwater is collected and stored for cooling purposes. Another aspect is the regulation and storage of rainwater to manage floods and improve water utilization. This can be achieved through the implementation of rainwater collection systems, purification systems, and storage systems. Additionally, rainfall measurements and rainfall time series generation are important for understanding and modeling rainfall patterns. Stochastic simulators like STORAGE are used to generate long and high-resolution rainfall time series, which can be used for various hydrological purposes. Overall, the relationship between rainfall and storage involves the collection, regulation, and utilization of rainwater for various applications.
