  • 백미와 현미, 발아현미 찹쌀떡에 대한 소화율과 품질 특성을 살펴보았다. 또한, 소비자들에게 선호도가 높은 제품의 발아조건을 찾고자 백미와 현미, 발아현미찹쌀떡을 제조하여 색도, 기계적 품질 특성, in vitro 소화율 그리고 관능적 특성을 살펴보았다. 떡의 밝기를 나타내는 명도(L)는 현미보다 발아현미가 낮았으며 발아시간이 길어질수록 감소하였다. 반면 적색도(a)와 황색도(b)는 발아가 진행될수록 증가하여 전체적으로 색이 진해지는 것을 알 수 있다. 현미와 발아현미의 조직감 특성에서 경도, 부착성, 검성, 씹힘성은 현미가 가장 높았고 발아시간이 증가할수록 감소하는 경향을 보였으며 이로써 노화 지연에 도움을 줄 것으로 생각한다. 탄성은 시료 간의 큰 차이를 보이지 않았으며, 응집성은 현미와 발아현미가 백미보다 낮은 값을 보였다. 현미, 발아현미 찹쌀떡의 in vitro 소화율 결과 발아시간이 증가할수록 빠르게 소화되는 전분인 RDS 함량은 증가하고 소화되지 않는 전분인 RS 함량은 감소하는 특성을 나타내어 소화율이 크게 증가함을 알 수 있었다. 관능검사에서는 현미가 색, 부착성, 전체적인 기호도에서 높게 평가되었고, 발아시간이 증가할수록 색, 향에서 높은 점수를 받았지만, 부착성과 전체적인 기호도에서는 낮게 평가되었다. 이상의 결과로 찹쌀떡보다는 높고 찰현미떡과 비슷한 관능적 평가를 받은 10시간 발아한 현미로 만든 발아찰현미떡이 소화조절용 쌀가공식품으로 개발하기에 가장 적당할 것으로 생각된다.

  • In this study an automatic germinating system for germinated brown rice (GBR) was developed for accelerating germination and sprouting of brown rice. With the developed germinating system, the effects of anion radiation treatment on germination ratio, sprout growth, color quality and ${\gamma}$-aminobutyric acid (GABA) content of brown rice were investigated. This system can fast produce GBR by controlling the environmental conditions such as ambient temperature, relative humidity, and proper anion radiation. Air-phase germination with intermittent water spraying improved both germination ratio and sprout growth by about 2.2 and 2.3 times, respectively, compared to the conventional water soaking method. Our results strongly suggest that this germinating system that provides air-phase germination with intermittent water spraying and anion radiation can produce germinated brown rice with good color quality, high GABA content, and fast germination ratio as well as sprout growth.

  • Germinated brown rice (GBR) flour (0%, 25%, 50%, 75% and 100%) was added to brown rice (BR) and white rice (WR) flours and the densities of pound cake batters, morphology, color value, textural properties, sensory preference test, and hardness during storage were investigated, in order to develop health functional gluten-free rice pound cakes with high nutritional value. The rice was milled with the newly developed rice milling method. The entire shape and cross section of all cakes were symmetrical and desirable. The density of pound cake batter and weight of cake increased with addition of increasing GBR. Specific volume was not significantly different (2.1-2.4 mL/g). Textural properties of cakes between WR-GBR and BR-GBR showed different trends with adding GBR. On the sensory test, overall quality of rice pound cake did not significantly differ between rice flour types. Hardness of rice pound cakes and brittleness decreased with increasing addition of GBR flour. The hardness and the peak intensity at $2{\theta}=17^{\circ}$ decreased with increasing addition of GBR. The results, that addition of GBR flour improved the nutrition value and functionality of gluten free rice pound cakes and prevented staling of rice pound cakes during storage.

  • Objectives: This study is experimental comparison of brown rice (BR) and germinated brown rice (GBR) on upper gastrointestinal diseases animal models.Methods: The ICR mice were divided randomly into four groups of six animals each (Normal mice, gastritis mice, gastritis mice treated with BR, gastritis mice treated with 48h GBR). Gastritis was induced by administration of 0.5 mL 150 mM HCl-60% ethanol. Six-week-old male Sprague-Dawley (SD) rats were randomly divided into 7 groups after 1 week adaptation. (Normal rat, reflux esophagitis (RE) rat, RE rat treated with BR, RE rat treated with 24,30,36,48h GBR). Reflux esophagitis was induced by ligation with a 2-0 silk thread both the pylorus and the transitional junction between the forestomach and the corpus in SD rats.Results: HCl/ethanol-induced gastric mucosal injury mice were ameliorated mucosal damage upon histological evaluation by treatment of 48h GBR than BR. Optical changes such as hyperemia and multiple erosions were observed in the rats with RE and damage to the normal rats was not apparent. The oral administration of GBR significantly diminished against gross mucosal damage in a germination time-dependent manner. Also, the administration of GBR suppressed the biomarker of oxidative stress, reactive oxygen species (ROS) and produces peroxynitrite (ONOO-) in serum. However, the administration of GBR could not affect to the pH level secreted from stomach when compared with Control group.Conclusions: These findings suggest that GBR could have improving effects on upper gastrointestinal diseases in a germination time-dependent manner.

  • 본 연구에서 현미의 발아에 키토산을 활용함으로써 곰팡이 발생을 억제하고 기능성 생리활성 물질인 GABA의 생성을 증진시 킬 수 있음을 확인하였다. 100 ppm 키토산액에서 72시간 발아 는 현미파우더 그램당 1,035 nmole의 GABA를 보유하게 되어, 발아되지 않은 현미의 136 nmole, 불침종 발아 현미의 771 nmole, 100 ppm 젖산침종 발아 현미의 728 nmole GABA에 비하여 높은 것으로 조사었다. 발아에 의한 GABA 생성증진과 더불어 알라년의 생성증진 및 글루탐산, 아스파틱산, 세련의 함량 감소가 뚜렸하였다. 키토산처리에 의한 GABA의 생성 증진은 GABA 생성에 관여하는 글루탐산 탈탄산효소의 활성증진이 기여한 것 으로 조사되었다. 키토산액에서의 침종 발아는 물침종 발아나 젖산침종 발아에 비하여 곰팡의 발생빈도를 현저하게 낮추었다. 이들결과를 종합할 때 발아현미 제조시 키토산액을 사용하면 기 능성 물질인 GABA 함량이 증진되고 곰팡이등의 잡균의 오염을 줄힐 수 있어 양질의 발아현미를 얻을 수 있을 것으로 기대된다.

  • Brown rice is more nutritious than the commonly consumed white rice, however, the former is not widely accepted because of its coarse texture and difficulty in cooking. Germination is an easy technique to minimize the drawback of normal brown rice. The objective of this study was to investigate the effect of three different concentrations (1, 3, and 5% w/v) of turmeric extracts on the nutrient and antioxidant activities of germinated brown rice (GBR). The b (yellowness) values of the turmeric-treated GBR were significantly higher than that of the untreated control. Lower concentration (1%) slightly increased (3395.5 mg/kg) but higher concentrations (3 and 5%) reduced (1735.8 - 2393.7 mg/kg) the total mineral content in GBR, as compared to the control (3377.4 mg/kg). The amount of essential, non-essential, and total amino acids, including GABA, were increased with the concentration of turmeric extracts. The amount of essential amino acids was increased by 58.3, 71.5, and 88.3% with the application of 1, 3, and 5% extracts, respectively. The antioxidant potential of GBR was also enhanced with turmeric treatment. Overall results indicated that 1 or 3% turmeric treatment could be appropriate to enhance the nutritional and functional value of GBR.

  • This study was conducted to investigate the effects of electric current stimuli and high-voltage electric field treatments on brown rice germination. The brown rice stimulated by electrical current stimuli, functional electrical stimuli of a pulse type, and high-voltage electric field treatments were observed (Type I, II and III). Treatment Type I was a method of semi-soaking brown rice with electric current stimuli of 0.13 V/cm, 0.19 V/cm, and 0.25 V/cm into Petri-dishes for 72 hours. Type II was a method of semi-soaking brown rice with functional electrical stimuli of a pulse type(DC 1 V, 1 Hz, 5%, and duty cycles of 5%, 20%, and 35%) into Petri-dishes for 72 hours. Type III was a method of water-soaking with high-voltage electric field treatments for 60 hours. High-voltage electric field treatments at 15 kV/cm were also conducted for 2.5 min, 7.5 min, and 10 min, respectively. The germination rate and the sprout growth of brown rice germinated by electric current stimuli with 0.13 V/cm, 0.19 V/cm, and 0.25 V/cm were increased by about 10-15% compared with those of the control group. The germination rate and the sprout growth of brown rice germinated by functional electrical stimuli of pulse type(DC 1 V, 1 Hz, 5% duty cycle) were increased by about 10∼15% compared to those of the control group. Also, the best effective treatment among high-voltage electric field treatments was the 10 min group at 15 kV/cm. The germination rate and the sprout growth of brown rice germinated by this treatment of 10 min at 15 kV/cm were increased by about 10∼20% compared to those of the control group. The treatments of electric current stimuli and high-voltage electric field accelerated the germination rate and sprout growth of brown rice by about 10∼15% compared to those of the control group.

  • 발아현미 농축액(GBRC) 첨가량을 0, 1, 3 및 $5\%$(w/w)로 각각 달리하여 담근 배추김치의 품질변화를 조사하였다. 그 결과, pH는 발효가 진행됨에 따라 감소하는 경향으로 나타났고 총산도는 증가하는 경향을 보였다. 총당은 담금 직후 GBRC 첨가량이 많을수록 높은 함량을 나타내었고 발효가 진행됨에 따라 모든 구간들의 총당 함량이 꾸준히 감소하는 경향을 보였다. 환원당은 발효 3일째 약간 증가한 후 꾸준히 감소하는 경향을 나타내었다. 총균수와 Leuconostoc sp.은 발효가 진행됨에 따라 꾸준히 증가하여 숙성 12일째 최대치에 도달한 후 감소하는 경향으로 나타났고 Lactobacillus sp.은 숙성 9일째 최대치를 나타낸 후 일정한 균수를 유지하였다. 관능적 기호도에서는 발효전반에 걸쳐 GBRC $1\%$ 첨가구에서 전반적인 기호도가 높게 나타났다.
