The objective of this study was to evaluate the influence of sugar composition on the sensory attributes of seven baked sweet potatoes. The sugar composition was analyzed using high performance liquid chromatography. Results showed that the total sugar content of baked sweet potatoes increased significantly because of the formation of maltose. The maltose content dramatically increased after baking, and became the major sugar component of baked sweet potatoes. On the other hand, baked sweet potatoes were evaluated on a 7-point hedonic scale for sensory analysis. Overall acceptability results showed that the panelists preferred baked CYY95-26 and TNG66 over the other baked varieties. Because the correlation between overall acceptability and sweetness was the highest (r00.69, p<0.01), sweetness was determined as the most important factor determining the overall acceptability of baked sweet potatoes. Although sugar composition changed on baking, the overall acceptability of baked sweet potatoes was highly associated with the sucrose content.

Purpose -The purpose of this paper is to examine the impact of knowledge creation mode (e.g. goal-driven and goal-free) and organizational culture on knowledge creation performance in the context of high-tech manufacturing companies having received at least 20 patents. Design/methodology/approach -This paper uses an empirical study to examine the research model. Findings -Both goal-free and goal-framed creation modes are more likely to support knowledge creation, while the goal-driven mode is not likely to be favorable for knowledge creation. Manufacturing companies who are frequently looking for new ideas for product design and manufacturing technologies are more likely to adopt the goal-free creation mode. Adhocracy culture is more likely to be a predicator of product and manufacturing creation. Practical implications -This work provides policy implications for government and high-tech industry associations. A company whose cohesion comes mainly from the task achievements is likely to emphasize manufacturing creation. Companies who would like to emphasize goal achievement with respect to creation in manufacturing should form an organizational culture with a characteristic of market competition. Also, a company with both goal-free and/or goal-framed creation modes is more likely to be willing to frame its strategic decisions (or goals) and then freely look for creative ways to reach the goals. Originality/value -Manufacturing creation-based companies are becoming increasingly knowledge-sensitive as the competition becomes more intense, and thus may try multiple modes of knowledge creation to strengthen their creation capability in some areas. The research findings are quite remarkable because the impacts of culture and creation mode on creation performance are statistically examined.
