What is the optimal concentration and quantity of beta glucosidase to add during curing for vanilla beans?5 answersThe optimal concentration and quantity of beta-glucosidase to add during curing for vanilla beans can significantly impact vanillin production. Research suggests that the addition of exogenous enzymes like beta-glucosidase can enhance the conversion of glucovanillin to vanillin, increasing yields up to 7.00% on a dry weight basis. Studies have shown that the enzyme activity of beta-glucosidase in vanilla beans is maximized at pH 6.5 and 38°C, with Vmax and Km values of 62.05 units and 2.07 mm, respectively. Furthermore, optimizing the enzyme amount, reaction temperature, time, and pH can lead to a substantial increase in vanillin production, with an experimental yield of 4.63% achieved under specific conditions. Therefore, incorporating beta-glucosidase at an appropriate concentration, such as 84.2 mg under optimal conditions, can significantly boost vanillin extraction from vanilla beans.
What is curing?4 answersCuring is a preservation or processing technique used in various fields. In the food industry, curing involves the addition of salt, nitrate, or nitrite to create specific sensory characteristics, color, flavor, and stability in meat products. This method has evolved to include natural sources of curing ingredients from vegetables, meeting consumer demands for "natural" and "organic" products while maintaining quality and safety standards. In the construction sector, curing refers to maintaining adequate moisture and temperature in concrete after placement to enhance its strength, impermeability, and durability over time. Additionally, in manufacturing processes, curing can involve UV light exposure to workpieces in intervals to achieve desired properties. Overall, curing plays a crucial role in enhancing properties, preserving quality, and ensuring longevity in various applications.
What is the impact of curing temperature and time on mechanical behavior of PDMS?5 answersCuring temperature and time significantly influence the mechanical behavior of polydimethylsiloxane (PDMS). Research shows that for PDMS nanocomposites, an increase in curing temperature led to an increase in hardness but a decrease in ultimate tensile strength (UTS) with the addition of c-Fe2O3 nanoparticles. Additionally, the curing process of PDMS revealed a two-step decrease in the diffusion coefficient, indicating changes in crosslinking density during curing. Moreover, PDMS samples cured at different temperatures exhibited varying storage and loss moduli, emphasizing the importance of curing temperature for viscoelastic stability. Post curing at high temperatures was found to enhance the Young's modulus and strain-dependent behavior of PDMS films. Understanding these effects is crucial for optimizing the mechanical properties of PDMS in various applications.
How temperature effect curing on concrete pavement?3 answersThe temperature has an effect on the curing of concrete pavement. Elevated temperatures can improve the mechanical properties of concrete at earlier ages, but have no effect on permeability. Plastic sheet curing method can affect the development of pavement temperature, and the duration of curing with a plastic sheet can also impact the pavement temperature. The influence of elevated curing temperature on the mechanical properties of concrete has been studied, and it has been found that temperature has a strong effect on the strength of concrete. In the case of ceramsite concrete, the long-term compressive strength decreases significantly when cured at higher temperatures, but the addition of an accelerating agent can further decrease the strength. For geopolymer concrete, curing at elevated temperatures can increase compressive and tensile strength, while decreasing porosity.
Does w/c ratio greater than 0.4 requires internal curing in concrete pavements?5 answersConcrete pavements with a water/cement (w/c) ratio greater than 0.4 may benefit from internal curing. Internal curing involves providing water inside the concrete to enhance curing and improve its performance. Studies have shown that internal curing can be effective in improving the properties of concrete with high w/c ratios, such as delaying cracking, enhancing freeze-thaw resistance, and increasing dynamic modulus of elasticity. Additionally, internal curing has been found to be useful in concrete mixtures with relatively high w/c ratios under poor curing conditions, as it can lead to higher hydration, compressive strength, and lower permeability. Therefore, incorporating internal curing techniques, such as using recycled concrete aggregates or superabsorbent polymers, can be beneficial for concrete pavements with w/c ratios greater than 0.4, as it can improve their durability and performance.
