  • Biochemical studies such as growth rate, blood cholesterol and ascorbic acid contents in various organs of albino male rats were studied both in the instant food (Ramyon) and rice diet fed groups. The conclusion was as the followings: 1) Either single ramyon or rice fed rats were not shown growth rate properly. In supplementation of 10% or 20% protein on ramyon, growth rate was a little increased than that of the rice diet group. 2) No essential difference of vitamin C contents in various organs was observed between ramyon and rice diet fed rats. Serum vitamin C level of the rice diet group was shown higher than that of the ramyon group. 3) Blood cholesterol level of ramyon fed rats was higher than that of the rice diet group, whether single or protein supplemented diet was fed. 4) Liver lipid contents showed higher in the rice diet group than in the instant ramyon group.

  • This study was conducted to investigate instant coffee-mix intakes and its relations with anthropometric measurements, nutrient intake, and blood lipid in Gangneung and Samcheok residents. Coffee-mix is a mixture of instant coffee, sugar and coffee-creamer. It is a standardized convenience food in Korea. Recently, Koreans appear to consume too much of instant coffee-mix. The respondents of this study were 218 Koreans (Gangneung region 133, Samcheok region 85). The average age was 56.0 years (male), 57.5 years (female). They were divided into 2 groups, the instant coffee-mix drinkers and the non-drinkers. The nutrient intake and anthropometric measurements and their relations with coffee-mix intakes were analyzed (nutrient intakes were calculated by converting per 1,000 kcal and adjusted by age, region). As for male, body fat was significantly higher in coffee-mix drinkers (18.1 kg, 25.0%) than in non-drinkers (17.1 kg, 23.8%). In the case of females, serum triglyceride was significantly higher in coffee-mix drinkers (109.1 mg/dL) than in nondrinkers (102.9 mg/dL). Coffee-mix intakes and coffee-mix's contributions to energy were higher for participants from Samcheok (21.2 g, 4.7%) than those from Gangneung (16.6 g, 3.4%). In addition, for Samcheok, coffee-mix's contribution to energy was significantly higher in male (5.6%) than in female (4.2%). Coffee-mix intakes and energy contribution of coffee-mix were not significantly correlated with anthropometric measurements. Only HDL-cholestrol showed significantly negative correlation with coffee-mix's contributions to energy. Based on the above results, we conclude that usual instant coffee-mix intake may increase intakes of sugar and fat and exert negative effects on serum lipids. Therefore, it is needed to control too much instant coffee-mix intake in the dietary management of rural residents.

  • BACKGROUND/OBJECTIVES: Increased consumption of instant noodles has recently been reported to be positively associated with obesity and cardiometabolic syndrome in South Korea, which has the highest per capita instant noodle consumption worldwide. This study aimed to investigate the association between instant noodle consumption and cardiometabolic risk factors among college students in Seoul. SUBJECTS/METHODS: The study subjects consisted of 3,397 college students (1,782 male; 1,615 female) aged 18-29 years who participated in a health checkup. Information on instant noodle consumption was obtained from the participants' answers to a question about their average frequency of instant noodle intake over the 1 year period prior to the survey. RESULTS: Statistical analysis using a general linear model that adjusted for age, body mass index, gender, family income, health-related behaviors, and other dietary factors important for cardiometabolic risk, showed a positive association between the frequency of instant noodle consumption and plasma triglyceride levels, diastolic blood pressure, and fasting blood glucose levels in all subjects. Compared to the group with the lowest frequency of instant noodle intake (${\leq}1/month$), the odds ratio for hypertriglyceridemia in the group with an intake of ${\geq}3/week$ was 2.639 [95% confidence interval (CI), 1.393-5.000] for all subjects, while it was 2.149 (95% CI, 1.045-4.419) and 5.992 (95% CI, 1.859-21.824) for male and female students, respectively. In female students, diastolic blood pressure was also higher among more frequent consumers of instant noodles. CONCLUSIONS: Our results suggest that frequent consumption of instant noodles may be associated with increased cardiometabolic risk factors among apparently healthy college students aged 18-29 years.

  • In order to enrich the nutritional value of instant noodle and diverse utilization of Alaska pollack meat paste(AMP), several quality parameters of instant noodle mixed with AMP as enrichment of protein were investigated. Protein and amino acid contents of instant noodle were increased to $4.7\%\;and\;4,\;006.1mg\%$ by incremental level up to $30\%$ of AMP. Hardness, cooking weight and volume of noodle were also increased by the increments of AMP added, but tensile strength and soup turbidity were decreased. Sensory scores in flavor, color and soup taste of instant noodle mixed with AMP were revealed higher than that of without AMP, but texture scores were decreased with the increase of the AMP over $20\%$.

  • The shelf-life of instant noodle stored at $35{\sim}65^{\circ}C$ under dark condition was estimated from the change of hexanal content, which was linearly increased as the storage time increased. The rate constants of hexanal production at various storage temperatures followed Arrhenius relationship. The activation energy and $Q_{10}$ calculated were 12.7 kcal/mole and 1.92, respectively. The rancid flavor was organoleptically detected after 6 days at $65^{\circ}C$ and 13 days $50^{\circ}C$, at which the content of hexanal was 3.5 ppm. The shelf-life of instant noddle at $21^{\circ}C$ based on $Q_{10}$ value of hexanal production was about 110 days. The changes of acid value and peroxide value of instant noodle during storage followed similar pattern to those of hexanal. The activation energy and $Q_{10}$ for both acid value and peroxide value were 16.0 kcal/mole and 2.55, respectively. The hexanal content showed a high positive correlation with acid value as well as peroxide value at all storage temperatures.

  • This study produced instant Gochujang(red pepper paste) with enhanced convenience by increasing nutritional value and palatability, and by reducing production period, adding in the red pepper seed in the red pepper paste production in order to increase the use of the red pepper seed that is not used often as a food ingredient even though its nutrition value when producing red pepper paste was proven. Moisture content, pH, L-value, a-value, b-value, sugar contents, and salinity of instant Gochujang tended to increase as the amount of red pepper seed increased, while viscosity manifested the opposite trend. Sensory evaluations were conducted on instant Gochujang to assess differences in characteristics, which demonstrated that as the amount of red pepper seeds powder increased, the intensity of redness for the red pepper paste's external appearance, luster, spicy flavor and taste, and savory taste were evaluated strong. Meanwhile, fermentation value, which is red pepper paste's foremost weakness was evaluated as weak. Moreover, there was no difference in the size of the grain when compared to the contrast group consisting of regular red pepper paste. The results of preference test demonstrated that the RG3 with 30% of red pepper seed is optimal in terms of the external appearance, taste, texture and overall preference.

  • Metabolic syndrome is associated with risk of developing cardiovascular disease and type 2 diabetes, and incidence of metabolic syndrome is showing an increasing trend. Recently, coffee intake is argued to have an effect on the gut-brain axis, and it is widely recognized has being associated with many beneficial effects, including those related to metabolic imbalance. However, it is essential to understand how the dietary aspects of coffee intake and type of coffee intake affect diet and overall health. The association between coffee consumption and health is still controversial, and the average body weight of the Korean population is increasing. Therefore, this study focused on analyzing the effects of instant coffee (particularly instant coffee mix) in Korea, especially with respect to metabolic syndrome. The study was conducted on participating subject's that visited Sun-Han hospital, and instant coffee mix intakes and metabolic risk factors during the study period were examined from July 2015 to June 2016. The results showed that waist circumference (r=0.405, P=0.036) and serum triglyceride level (r=0.435, P=0.023) were positively correlated with instant coffee mix intakes. In addition, instant coffee mix intakes were significantly associated with serum triglyceride level in subjects who consumed more than 1 cup/d of coffee (P<0.05). Therefore, subjects should be careful about fat intake and be educated about the type and frequency of coffee intakes.

  • Although instant coffee is less palatable than freshly brewed coffee, it is widely consumed primarily due to its convenience. Frequently, instant coffee is consumed in the form of a coffee-mix. It contains coffee creamer or dried skim milk, and sugar in addition to soluble coffee. The aim of this study was to investigate the volatile aroma compounds (VACs) of instant black coffee mixed with coffee creamer or dried skim milk by Gas Chromatography-Headspace-Solid Phase Microextraction (GC-HS-SPME) and sensory evaluation. A total of 16 different coffee samples including instant black coffee and coffee mixes with coffee creamer or dried skim milk, were chosen for this study. The coffee samples contained several common VACs such as pyrazine, pyridine, and pyrrole. Sensory evaluation indicated that the flavor intensity of coffee mix was less pronounced than that of instant black coffee alone. Coffee creamer and skim milk had little distinctive aroma per se; however, they significantly contributed to the flavor profile of coffee mixes, suggesting that coffee creamer and skim milk acted as flavor modifiers in coffee mix.

  • To develop the Instant Nuroong-gi in a short reconstitution time, we made puffed Instant Nuroong-gi samples and investigated their physicochemical characteristics. The Nuroong-gi was prepared using a Japonica variety with three different cooking conditions: steam cooker(process A), pressure cooker (process B) and cabinet cooker(process C). The Instant Nuroong-gi is produced by adding water to the Nuroong-gi which is broken into the size of 0.5~1.0cm. The amount of the added water is 40% of the weight of the broken Nuroong-gi. And it was puffed at 160~17$0^{\circ}C$ for 30 secands. The water binding capacity of Instant Nuroong-gi samples was 7.2 at process A, 6.5 at process B and 6.6 at process C. The total sugar content of Instant Nuroong-gi samples in hot water reached at the highest level at 3-minute cooking time. Through the sensory evaluation by a panelists, we discovered that Instant Nuroong-gi prepared by a steam cooker showed the highest roasted nutty taste, hardness, stickiness and overall acceptability. And Instant Nuroong-gi prepared by a pressure cooker showed the highest color, clearness, and roasted nutty flavor. Correlation coefficients between overall acceptability and other sensory attributes of Instant Nuroong-gi indicated that hardness had the most significant correlation to sensory evaluations. When we compared the results of color test with those of sensory evaluation of Instant Nuroong-gi prepared by three different cookers, we discovered that panelists preferred yellow Instant Nuroong-gi prepared by a pressure cooker. We found some morphological properties of Instant Nuroong-gi as a result of the comparison of the crystalization by a X-ray diffraction analysis and the observation of the shapes by a the scanning electron micrographs.
