In Cote d’Ivoire, they are commonly known as “bissap” and are of great interest to local people, who use them to make an eponymous herbal tea. This drink has potential medicinal and nutritional value (Khan et al., 2022). Nine (9) samples of dried flowers of the plant, packaged in 3 g sachets of a local Kuinafo brand, were used for physico-chemical analyses. Heavy metals, mineral salts, ash and moisture content were determined using methods adapted from the Association of Official Analytical Chemists (AOAC). The results showed the presence of heavy metals at levels whose intake should take into account the weight of the consumer in the case of mercury and arsenic (0.5 mg/Kg and 0.7 mg/Kg respectively). Apart from lead, whose level was not compliant (1.310 mg/Kg for a CSHPF standard of 0.5 mg/Kg), cadmium had a regulatory level (0.18 mg/Kg for a CSHPF standard of 0.20 mg/Kg). Nutrient intakes were significant (calcium, iron and potassium respectively at 1.79 g/100g;17.27 mg/100g and 1.76 g/100g of dried Hibiscus sabdarrifa flowers) and the moisture content suggested that the dried flowers were better preserved. The study of the physico-chemical characteristics of Hibiscus sabdarrifa flowers has enabled us to highlight the importance of quality control and the need to prevent any adverse effects on consumer health.展开更多

文摘Based on the requirements of local high-quality economic development and addressing the critical task of transformation and upgrading in the tea industry,this paper systematically discusses the necessity and feasibility of constructing an optimal industrialization operation system driven by the dual wheels of"branding+standardization".The article first clarifies the connotation of high-quality development and the synergistic mechanism between branding and standardization.It then analyzes the current situation and bottlenecks of China's tea industry development.Subsequently,it proposes a dual-wheel drive strategy where branding enhances value and standardization guarantees quality,and designs a systematic implementation plan involving industrial chain synergy optimization and integrated support from government,industry,academia,research,and application.On this basis,strategies and suggestions are proposed,encompassing the starting point,standard focal points,key effort areas,innovation points,and target achievement points.The aim is to promote the tea industry to break through homogeneous competition,achieve value ascent,and provide important industrial support for regional high-quality development through the construction of the aforementioned system.
文摘Hibiscus sabdarrifa flowers are known the world over. In Cote d’Ivoire, they are commonly known as “bissap” and are of great interest to local people, who use them to make an eponymous herbal tea. This drink has potential medicinal and nutritional value (Khan et al., 2022). Nine (9) samples of dried flowers of the plant, packaged in 3 g sachets of a local Kuinafo brand, were used for physico-chemical analyses. Heavy metals, mineral salts, ash and moisture content were determined using methods adapted from the Association of Official Analytical Chemists (AOAC). The results showed the presence of heavy metals at levels whose intake should take into account the weight of the consumer in the case of mercury and arsenic (0.5 mg/Kg and 0.7 mg/Kg respectively). Apart from lead, whose level was not compliant (1.310 mg/Kg for a CSHPF standard of 0.5 mg/Kg), cadmium had a regulatory level (0.18 mg/Kg for a CSHPF standard of 0.20 mg/Kg). Nutrient intakes were significant (calcium, iron and potassium respectively at 1.79 g/100g;17.27 mg/100g and 1.76 g/100g of dried Hibiscus sabdarrifa flowers) and the moisture content suggested that the dried flowers were better preserved. The study of the physico-chemical characteristics of Hibiscus sabdarrifa flowers has enabled us to highlight the importance of quality control and the need to prevent any adverse effects on consumer health.
文摘The water conservancy construction and soil and water conservation projects in New China have reshaped the tea industry landscape in Xinyang City of Henan Province from multiple dimensions.In terms of hydraulic technology,engineering systems represented by the Nanwan Irrigation District redefined the watershed irrigation pattern,while the application of modern agricultural technologies such as sprinkler and electric irrigation accelerated the shift from traditional experience to scientific management in tea garden practices.Ecologically,systematic soil and water management significantly improved growing conditions,making it possible for tea cultivation to break through the traditional geographical limitation of"tea does not grow north of the Huai River."This integrated governance model not only laid the foundation for the northward expansion of Xinyang's tea industry across the Huai River but also facilitated the transition toward scale and intensification through improved irrigation infrastructure and the breeding of cold-resistant tea varieties.Ultimately,driven by the tripartite interactive mechanism of"engineering governance-ecological improvement-spatial expansion,"the tea industry in Xinyang achieved a historic leap from traditional production to modern intensive development.
