Various jellies were produced depending on the type and concentration of gelling agent (nine types), which added a single or double agent in jelly production. Firstly, jelly was manufactured using nine different single gelling agents and characterized. Secondly, six suitable gelling agents were selected to combine double gelling agents among nine gelling agents. To find the optimum gelling agent condition, jelly was intentionally made around 3.6-3.7 pH and 4- 5 N fracturability. A total of 1.2% gelling agent (both single and double agents) was suitable for making jelly (3.6- 3.7 pH, 4-5 N fracturability). According to the analytical result, the optimum single gelling agent was κ-carrageenan and gellan gum, while a suitable combination of double gelling agents was κ-carrageenan and gellan gum at ratios of 1.0:0.2, 0.8:0.4, and 0.6:0.6 and agar and locust bean gum at ratios of 0.8:0.4, 0.6:0.6.
This study was done to evaluate the effects of various gelling agents on textural properties of omija pyon. As a gelling agent, mungbean starch had been used in traditional omija pyon. In this experiment, gelatin and pectin were also tried for better texture. The results of this study were as follows; 1) One percent pectin addition showed desirable textural properties in both starch and gelatin jelly. 2) No significant effect on rheological values was found according to various sugar concentration(10, 15, 20%). 3) There was a saving effect of sugar concentration when adding 1% pectin to starch jelly, comparing textual properties as sensory scores.
본 연구에서는 O/W 제형 마스카라에서의 레올로지 특성과 함께, 마스카라 내의 수상 폴리머에 따른 발림성과 볼륨과의 상관관계를 살펴보고자 하였다. 마스카라의 레올로지 특성은 최종 마스카라 내용물과 점증 수용액으로 측정하였으며, 수상 점증 폴리머는 hydroxyethylcellulose (HC), carboxymethylcellulose (CMC), hectorite, sodium magnesium silicate (SMS), hydroxyethyl acrylate/sodium acryloyldimethyl taurate copolymer (HS), polyacrylate 13/polyisobutene/polysorbate 20 (PPP)를 사용하였다. 실험결과 2.0 wt%의 수용액 점도에서 아크릴계 점증 폴리머인 HS와 PPP가 가장 높은 부착력을 가졌으며, 이는 마스카라의 품질 특성 중 볼륨과 밀접한 관계를 가졌다. 또한 HC와 SMS, HS를 0.2 wt% 함유한 마스카라를 oscillation stress가 1.0 ∼ 1,000 s-1의 범위에서 저장계수를 측정한 결과 높은 진동힘 구간인 100 ∼ 1,000 s-1 구간에서 SMS의 저장계수가 가장 낮게 측정되었고, 이는 마스카라 특성 중 발림성 항목과 밀접한 관계를 가졌다. 이는 O/W제형의 마스카라에서 수상 점증제의 구조적인 특성이 마스카라 물성에 크게 영향을 주어 최종적으로 볼륨과 발림성 등의 사용감에도 큰 영향을 주고 있음으로 해석할 수 있다.
This study was carried out to investigate the effect of polyamines, salt strength. sucrose and gelling agents on the regeneration of plantlets by meristem culture of Aloe arborescens Mill. and Aloe vera L.. Shoot multiplication was more effective when 10mg/ l spermine in Aloe arborescens and 1mg/ l spermidine in Aloe vera added into MS medium than when other polyamines were treated into media. A quarter strength of MS medium was effective for rooting of shoots regenerated. Higher concentration of sucrose (45g/ l) was more effective for shoot regeneration. Addition of 4g/ l gelrite into the medium was effective for induction of multiple shoots from Aloe than that of agar or other concentrations of gelrite. When plantlets regenerated from meristem culture were transferred to pot. survival rate of plantlets was 80% on perlite and was 95% on vermiculite. respectively.
