Molecular gastronomy is a science that deconstructs the classic haute cuisine and applies science knowledge and laboratory techniques to create textures and flavors in unusual ways. The term 'Molecular Gastronomy' was introduced in 1988 by French chemist 'Herve This' and Oxford physicist 'Nicholas Kurti'. It has since been adopted by both world culinary establishments and scientists, from 'El Bulli' to 'Harold McGee'. Since most world-top prestigious restaurants and chefs were enthralled by this revolunary culinary movement, molecular gastronomy and molecular cooking have drawn a growing interest of lots of Korean people in the food industry until now. However, Korean foodservice industry is unlikely to be ready to develop this advent-garde culinary movement because molecular gastronomy is still an insufficiently established concept of culinary science and philosophy in Korea. Besides, there are many clumsy abuses of putative and clinically unproven bio-chemical components in kitchens and restaurants in the name of culinary science or culinary arts. Such a careless approach and attitude towards an important exercise like a cooking is highly deplorable. Thus it is still too far early to expect the prospective path of molecular gastronomy in Korea without understanding the core principle of molecular gastronomy and having any cultural support.

The purpose of this study was to apply molecular gastronomy and spherification methodology to persimmon deserts. We prepared 'persimmon calcium alginate beads' and investigated their physical and sensory characteristics by adding different concentrations of sodium alginate (0.4, 0.6, 0.8, and 1.0%). Lightness and yellowness decreased significantly as the concentration of sodium alginate increased. However hardness, springiness, chewiness, cohesiveness, and resilience but not adhesiveness tended to increase as the concentration of sodium alginate increased. The thickness of the beads increased as the concentration of sodium alginate increased. In contrast, the thickness of the membrane decreased as the concentration of alginate increased from 0.8 to 1.0% suggesting that the amount of sodium alginate had reached a critical point. Quantitative descriptive analysis showed that voluminosity, springiness, hardness, chewiness, and residue tended to increase as the concentration of sodium alginate increased. Overall preference reached a peak at 0.4% sodium alginate.

본 연구는 분자요리 기법인 spherification 기법을 이용하여 감(Diospyros kaki)을 구형화시켜 염화칼슘의 농도와 반응시간에 따른 감 칼슘 알지네이트 비드의 물리적 및 관능적 특성을 연구하였다. 염화칼슘의 농도(0.5, 0.75, 1.0 %)와 겔화 반응시간(2, 4, 6, 8, 10 min)에 따른 감 칼슘 알지네이트 비드의 색도 측정결과, 염화칼슘의 농도와 반응시간이 증가될수록 명도와 황색도는 감소하고 적색도는 증가하였다. 부착성을 제외한 경도, 탄력성, 씸힙성, 응집성, 복원성은 염화칼슘의 농도와 반응시간이 증가될수록 증가하는 경향을 보였다. 비드의 막 두께와 형태의 분석결과 염화칼슘의 농도와 반응시간이 증가할수록 비드의 감퓨레 속에 있는 염화칼슘과 소디움 알지네이트의 반응이 활발해져 막 두께가 두꺼워지는 경향을 나타냈다. 정량적 묘사분석 결과 염화칼슘의 농도와 반응시간이 증가할수록 입체감, 탄력성, 단단함, 씹힘성, 잔여감은 모두 증가하였으며, 노란정도, 투명성은 증가할수록 감소하는 경향을 보였다. 기호도 검사 결과 색상, 향, 맛에서는 염화칼슘의 농도와 반응시간에 따른 유의적 차이를 보이지 않았으나 질감과 전반적인 기호도에서는 염화칼슘 0.5%의 Control 시료가 가장 높은 평가를 받았다. 칼슘 알지네이트 비드의 물리적 관능적 특성에 염화칼슘의 농도와 반응시간이 영향을 끼침을 알 수 있다.

This study was performed to investigate the changes in meat quality characteristics of the sous vide cooked chicken breast during refrigerated storage at 4℃ for 14 d between before and after sous-vide cooking. Cooking loss and shear force were significantly increased, whereas expressible drip was significantly decreased along with reduction in the water holding capacity in both of two groups. Redness of meat juice was significantly (p<0.05) increased during storage, and considerably increased in the refrigerated samples after sous-vide cooked at the 7 to 10 d. The thiobarbituric acid reactive substances (TBARS) was significantly increased and was higher in the refrigerator stored chicken breast samples after sous-vide cooking. The volatile basic nitrogen (VBN) value was significantly increased in both groups, but the VBN value of the stored raw meat sample before sous-vide cooking was increased at an early storage, while the VBN value of the stored sample after sous-vide cooking was increased gradually in this study. Total viable counts and coliform counts were significantly decreased during storage, and coliforms were not detected after 7 d of storage in both groups. Salmonella spp. was not detected during the whole studied period. The outcome of this research can provide preliminary data that could be used to apply for further study of chicken breast using sous-vide cooking method that could be attractive to consumers.
