Abstract
Purpose
The purpose of this study is to compare the oxidative stability of non‐hydrogenated cottonseed oil with that of the partially hydrogenated oils commonly used as a deep‐fat frying medium by the restaurant industry when used to prepare French fries in order to reduce trans‐fatty acids.
Design/methodology/approach
Stability characteristics of non‐hydrogenated cottonseed oil and two hydrogenated oils, canola and soybean, were evaluated in deep‐fat frying applications. French fries were analyzed for total polar compounds, and the oils were analyzed for iodine, peroxide, p‐anisidine and totox values, and free fatty acids.
Findings
Canola and soybean oil had significantly lower iodine values than cottonseed oil. Free fatty acid values were not significantly different among the oils (0.256 per cent oleic acid). Initially cottonseed oil had higher peroxide, p‐anisidine, and totox values compared with canola and soybean oil. However, as days of frying increased, values trended closer together. Total polar compounds were similar. All oil types were comparable in terms of their stability characteristics under the conditions used in this study.
Research limitations/implications
Research with additional food product and under more stressful conditions would be beneficial.
Practical implications
Hydrogenation increases trans‐fatty acid content. Consumption of trans‐fatty acids has been associated with increased risk of heart disease. Non‐hydrogenated cottonseed oil may be a viable alternative to popular hydrogenated oils currently used in the restaurant setting.
Originality/value
Restaurants are being pressured by health officials to choose healthier oil. This research article can help restaurants make an informed choice.

Abstract
The deadhead subculture – centered around the band Grateful Dead – has been active for 50+ years. Despite its longevity, academic work is sparse compared to other music subcultures. Given its durability and resilience, this subculture offers an opportunity to explore subcultural development and maintenance. I employ a contemporary, symbolic interactionist approach to trace the development of deadhead subculture and subcultural identity. Although identity is a basic concept in subculture research, it is not well defined: I suggest that the co-creation and maintenance of subcultural identity can be seen as a dialectic between collective identity and symbolic interactionist conceptions of individual role-identity.
