Quality and Consumer Studies in the USA of African Herbal Teas for the Natural Product Industry Development in Sub-Sahara Africa

摘要

In Africa, many plant products have been used over the centuries as herbal teas, and as popular local drinks used as refreshing beverages and for their perceived health and medicinal attributes. With the regionalization and globalization of foods, beverages and natural products, the introduction of new drinks such as African teas into other countries and even regions in Africa can provide new herbal teas to a wide range of new consumers. African herbal teas can also be exported outside the continent into Europe, North America and Asia and in doing so have potential to contribute to the economic development of those involved in the collection or production, processing, packaging and distribution of such products. Information on the quality, chemical analysis and health attributes, and consumer response to new products contribute to the commercialization and marketing success of any product. The aim of this study was to assess the quality parameters, proximate analysis of a few selected African herbal teas (Honeybush, Kinkeliba, Lemongrass, Lippia, Rooibos) during three consecutive years (2004 through 2006). This study also sought to conduct a consumer study to evaluate the intensity of color and flavor and liking ratings for four different African teas to an American college-based audience in the USA.
