  • Sensory and consumer science is one of the four core sciences in food science training. In early years, this field of studies are focused on providing food technologists information of sensory attributes of food for quality control and product optimization, and referred as sensory evaluation or sensory science interchangeably. Yet, during the last decades, its scope has been much broadened looking at sensory properties of food not just as product attributes but consumer-perceived properties, emphasizing human experience. Attentions are increased for sensory fundamentals(sensory psychology and physiology) and multidisciplinary integration of theories and measurement methods for improving satisfaction of consumers' sensory experience and promoting healthy eating and wellbeing. The Sensory Evaluation(SE) division of Korean Society of Food Science and Technology(KoSFoST) has recently changed its name to Sensory and Consumer Science(SCS) division in order to address such evolution of the field and sensory professional's role.

  • Consumer's interest in sustainable livestock farming methods has grown in response to concerns for the environment and animal welfare. The purpose of this study is to examine the different influences of sustainability product information on sensory characteristics and purchase behaviors. To accomplish this aim, the study used salami, which is an Italian-style sausage processed by fermentation and drying. Three different types of information were provided: salami made from the pork of an antibiotic-free pig (SMAFP), of an animal welfare pig (SMAWP), and of a grazing pig (SMGP). This study was conducted as an off-line experiment with Korean participants (n=140). As a result, there were sensory differences according to the sustainability information. For the SMAFP, it had a significant difference in, sourness (p<0.05). With the SMAWP, there was a difference in gumminess (p<0.10), and the SMGP had significant differences in sourness (p<0.01), sweetness (p<0.01), andmoisture (p<0.05). Moreover, the purchase intention and willingness to pay were significantly higher when the sustainability information was given. Especially, among the three types of salamis, participants were willing to pay the most for the SMAWP. This is one of the first consumer studies to investigate sensory evaluation and purchase behavior for various types of sustainable livestock production. These results contribute by helping sustainable meat producers and marketers become aware of the kind of sustainable information to which consumers are sensitive.

  • Volatiles in Artemisia princeps Pampan. cv. sajabal (sajabalssuk) and A. princeps Pampan. (ssuk) treated with different processing were analyzed using headspace-solid phase microextraction (HS-SPME)/gas chromatography- a mass selective detector (GC-MS). Sajabalssuk and ssuk were treated with steam distillation (SD) and freeze-dried/steam distillation (FD/SD) while controls were raw sajabalssuk and raw ssuk. Sajabalssuk had significantly more total volatiles than ssuk in control and FD/SD treated samples (p<0.05). Major volatiles in raw sajabalssuk were 2-hexenal, 1,8-cineol, trans-caryophyllene, and hexanal while those in raw ssuk were 1-hexanol, ${\beta}$-myrcene, limonene, and 2-hexenal, which implies that substantial lipid oxidation occurred in raw samples. Sajabalssuk with SD and FD/SD treatment had higher peak areas of 1,8-cineole, 4-terpineol, 1-octen-3-ol, and ${\alpha}$-terpineol while ssuk with SD and FD/SD treatment possessed 1,8-cineol, camphor, borneol, artemisia ketone, ${\alpha}$-thujone, and 1-octen-3-ol, which showed that steam distillation produced more volatiles from terpenoids than raw samples. Based on the results of HS-SPME/GC-MS, relative amounts of volatiles from lipid oxidation including 2-hexenal, hexanal, and 1-hexanol were reduced in sajabalssuk and ssuk with freeze-drying and/or steam distillation treatment.

  • Volatile profiles of beverages and encapsulated powders containing Artemisia princeps Pampan extracts were analyzed by solid-phase microextraction-gas chromatography/mass spectrometry during production and storage. Beverages containing 0.32 and 0.64% extracts were stored at room temperature for 8 weeks and $60^{\circ}C$ for 8 days, respectively. Encapsulated particles were stored at room temperature and $60^{\circ}C$ for 8 days. Total volatiles in beverages decreased significantly during storage, irrespective of storage condition (p<0.05). Terpenoids, including cymene, thujone, and ${\beta}$-myrcene, were major volatiles in beverages, and some volatiles including ethylfuran, vinylfuran, and 2-fufural increased in 60oC samples only. Total volatiles in microcapsules at room temperature were not significant different for 8 days (p>0.05), whereas those at $60^{\circ}C$ increased by 16.5 times. Limonene was the most detected volatile in microcapsules, and aldehydes such as hexanal, pentanal, and octanal, and furans such as 2-butylfuran and 2-pentylfuran increased in the $60^{\circ}C$ samples, which may have originated from oxidized lipids used in the microcapsules.
