What is the standard method for measuring ash value in honey?5 answersThe standard method for measuring ash value in honey traditionally involves gravimetric analysis, which determines the mineral content through incineration of the sample. However, alternative methods like thermogravimetry (TG/DTG) have been explored. Electrical conductivity (k) measurement is also utilized as a proxy for ash content, with a linear regression model established for Slovenian honey. Another innovative approach involves a new indirect method based on a multiple regression model for determining total ash content in bee honey varieties, offering a time-saving and effective solution for quality control. Additionally, Thick-Target Particle Induced X-ray Emission (TTPIXE) analysis directly on honey ashes provides quantitative data on various elements, aiding in sample characterization and environmental monitoring. These diverse methods showcase the evolving techniques for ash value determination in honey.
How does the taste and texture of dishes compare when honey is used instead of sugar?5 answersWhen honey is used instead of sugar in dishes, the taste and texture can vary based on the specific dish. Research indicates that in cake making, consumers highly prefer cakes baked with honey over those with sugar due to the implications of sugar on diabetic consumers. In chiffon cake, panelists favored the flavor and overall aspects of cakes made with honey, while cakes with sugar were preferred in terms of appearance and texture. Additionally, in ice cream production, samples with honey were found to be more palatable and smooth compared to those with sugar, with no microbial issues observed in the honey samples. Moreover, honey-incorporated sweet rolls had a lower glycemic index compared to rolls made with cane sugar and jaggery, making them suitable for individuals with impaired glucose tolerance.

How can we measure the nectar volume of flowers in a community?5 answersNectar volume of flowers in a community can be measured using various methods. One approach is to use small filter paper strips as wicks to collect floral nectar, which provides information on nectar sugar production throughout the day and flowering season under natural conditions. Another method involves the use of optical fibers to deliver light directly inside the flower and measure the refractive properties of the nectar without extracting it, which is particularly useful when the nectar is secreted in small quantities. Additionally, floral abundance and nectar sugar production data can be combined to quantify the nectar supply of different landscapes, including urban areas, farmland, and nature reserves. This allows for the comparison of nectar sugar distribution among different land uses within cities and the identification of high-nectar plants of conservation importance.
How to extract fulvic acid from ash?5 answersFulvic acid can be extracted from ash using different methods. One method involves mixing the ash with sulfuric acid, hydrochloric acid, citric acid, or phosphoric acid at room temperature, followed by blending and static settlement. Another method involves using a sulfuric acid-ethanol method, which includes air drying, sieving, water washing, and centrifugal separation of coal samples, followed by adding ethanol water and concentrated sulfuric acid for oscillating reaction and leaching. Additionally, a method for preparing sulfuric acid by desulfurization ash can also be used, where the ash is mixed with pyrite powder and sprayed into a fluidized bed combustion boiler for decomposition reaction. These methods provide cost-effective ways to extract fulvic acid from ash and achieve high product purity.
