Nutritional evaluation of Kedrostis africana (L.) Cogn:An edible wild plant of South Africa

Objective:To evaluate the nutritional composition and elemental constituents of Kedrostis africana and their safety aspect.Methods:Proximate parameters(moisture,ash,crude fibre,crude fat,proteins,and carbohydrate and energy) were evaluated using ALASA methods,and elemental analysis by ICP-OES technique.Results:The results from nutritional analysis showed that the tuber used for this study had a low content of crude fat and high content of ash,crude protein,crude fibre,carbohydrate and energy having the recommended dietary allowances.The tuber was rich in major minerals Na,K,Ca and Mg,there was sufficient amount of trace elements Fe,Cu,and Zn while the anti-nutrients oxalate,phytate,alkaloids,and saponins were detected in amounts that are not harmful according to Food and Agriculture Organization/World Health Organization.Conclusions:The outcome of this study suggests that this wild plant has very good nutritional potentials to meet the recommended dietary allowance and it could be a cheap source of essential nutrients that may ameliorate most nutritional challenges and can contribute remarkably to the amount of nutrient intake in human and animal diet.

Perceptions of Local People toward Wild Edible Plant Gathering and Consumption:Insights from the Q-method in Hani Terraces

Wild edible plants(WEPs)can provide a variety of provisioning services and cultural services but they are currently under-utilized.Understanding farmers’perceptions of the collection and consumption of wild edible plant resources is essential for promoting local socio-ecological system resilience and local wild plant resource use.This paper uses the Q-method to investigate the main perspectives of farmers toward collecting and consuming wild edible plants in the Honghe Hani Terraces region of Yunnan Province.This analysis identified four main perspective types among the farmers,including market-driven,household user-driven,cultural service seekers,and tradition followers.It revealed the main factors that limit and facilitate farmers’WEP collection and consumption,including limitations due to loss of traditional knowledge,and changes in socioeconomic conditions that negatively affect WEP collection and consumption;while,on the other hand,the demand for WEP-related cultural services and the presence of a strong culture slowed down changes in dietary structure,which in turn have maintained WEP collection and consumption.The Q-method can help in identifying the relationship between community residents and local wild plant resource use in rapidly transitioning areas and in identifying the barriers that affect the resilience of local socio-ecological systems.
