This study was conducted to develop a healthy functional food material using mycelial extract of Phellinus sp. Jangsoo and GMPL48007 were selected as suitable strains because of good mycelial growth and high functionality. The highest total polyphenols and reducing power were observed in the Jangsoo strain and the radical scavenging was shown in GMPL48007. Among grains media, whole-grain wheat had the highest extraction yield from mycelia of selected strains; especially, the GMPL48007 strain showed the highest content of beta-glucan.

Beverages can vary in their appropriateness depending on the context of their different uses; therefore, an intention to consume a beverage is likely dependent on the context of its use. This study associated the consumer acceptability of commercial beverage products examined in a previous study (Kim and others, 2013) with its appropriateness under different use contexts. Consumers (n=360) were divided into two conditions: blind and brand. Consumers rated appropriateness for 13 use contexts for each beverage product. The results indicated that the contextual appropriateness were significantly different among the beverage samples and seemed to be positively influenced by the acceptability of beverages. The beverages with higher liking scores were more appropriate in a greater number of contexts, including "when tired", "refreshing", and "rest". However, there were inappropriate contexts (e.g., "while weight watching", "after exercise", "with a meal", and "health care") regardless of degree of acceptability. In the brand condition, some differences in contextual appropriateness were observed when comparing results from the blind condition (e.g., "with a meal", "health care").
