  • The quality characteristics of fish cakes containing different amounts of mealworm powder were analyzed. The moisture content decreased while water absorption index increased with the addition of mealworm powder. The L value was decreased but a value was increased as the amount of mealworm powder added increased. The hardness and cutting forces were 2.63 and 0.09 kg, respectively, in the 0% fried fish cake. With an increase in the amount of mealworm powder, the hardness and cutting force increased to 3.18 and 0.14 kg in the 9% fried fish cake. The pH did not differ with the addition of mealworm powder. During the sensory evaluation, 0 and 3% groups had the highest scores in color, flavor, taste, texture and overall acceptance. These scores decreased with increasing mealworm powder content. Based on the results of the quality characteristics and sensory evaluation, the amount of mealworm powder addition suitable for fish cake production was 3%.

  • Inhibitory effects on bacterial growth by using lysozyme and mixtures of it with other antibacterial substances (sodium hexametaphosphate and sodium pyrophosphate) were investigated against the 7 kinds of hacterial strains isolated from putrefied surumi products. The growth inhibitory concentrations of lysozyme and lysozyme + sodium hexametaphosphate + sodium pyrophosphate against the bacteria were added to kamaboko, imitation crab meat and fried surumi, then viable cell count, pH and VBN were examined during the storage at $30^{\circ}C$ for 7 days. Lysozyme showed growth inhibitions against 6 of 7 isolates and the inhibition effect of mixture of antibacterial substances was multiplied against all the isolates compare with those of its individual use. Growth inhibitory effect of the substances on the bacteria was high in order of lysozyme + sodium pyrophosphate + sodium hexametaphosphate, lysozyme + sodium hexametaphosphate, lysozyme + sodium pyrophosphate and lysozyme. The most effective inhibitory concentration of mixture of the antibacterial substances in kamaboko and imitation crab meat was $0.05\%$ of lysozyme, $0.5\%$ of sodium pyrophosphate and $0.1\%$ sodium hexametaphosphate. But the bacterial growth was slightly inhibited in fried surumi even if the same concentration of the dipped mixture and the effect of the mixture was less than that of $0.2\%$ sorbic acid.

  • Quality stability and utilization of sardine protein concentrates were investigated. pH, water activity and amino-nitrogen contents of autoclaved and boiled products were little changed during the storage of 60 days. Available lysine contents of the both products at the initial stage of storage were 5.58g/16g-N and 5.69g/16g-N, respectively. But the available lysine contents and digestibility of the both products decreased slightly with increasing of storage time. Lipophilic and hydrophilic brown pigment formation of the both products increased during storage of 60 days, but peroxide value(POV) and thiobarbituric acid(TBA) value decreased. Total amino acid contents of the both products were in the range of $88.99{\~}89.90g/16g-N$, and the predominant ones were glutamic acid, aspartic acid, leucine and lysine. From the sensory scores of model snack, it is concluded that the sardine protein concentrate can be used as a source material for snack.

  • Flavor compounds of pentane, hexane, hexanal and total volatiles formed during $65^{\circ}C$ storage of ramyon fried in palm oil with ${\alpha}-tocopherol$, RHA, TRHQ, rosemary extract or defatted ricebran extract were determined by static headspace gas chromatography. The levels of the antioxidants used in the frying oil were 100 or 200 ppm, and an additional level of 300 ppm was employed in the case of ${\alpha}-tocopherol$ ${\alpha}-Tocopherol$ decelerated the formation of all the flavor compounds when used at 100 or 200 ppm, and the former was more effective than the latter. However, 300 ppm of ${\alpha}-tocopherol$ accelerated the flavor compound formation in ramyon during storage. One hundred ppm of BHA and TBHQ contributed to the reduction in flavor compound formation in the stored ramyon, whereas 200ppm level accelerated the compound formation. Rosemary extract and defatted ricebran extract lowered the flavor compound formation in ramyon when used at 100 or 200 ppm in palm oil. Their lowering effects were similar to that of ${\alpha}-tocopherol$, and superior to that of TBHQ. suggesting a possible utilization of defatted ricebran extract as a new natural antioxidant.

  • The oxidative stability of the ramyon prepared with ricebran oil fortified with ${\alpha}-tocopherol$, BHA, TBHQ, and ascorbyl palmitate+citric acid or blended with palm oil was studied to assess the suitability of the oil as the frying oil. The antioxidants were added to a ricebran oil at 0.02% level, respectively, while blended oils were prepared by adding a palm oil to the ricebran oil at ratios of 3:7, 5:5, and 7:3. Ramyon samples were prepared by frying steamed noodel with the oils. They were stored in dark at $35.0{\pm}0^{\circ}C$. for 90 days. Peroxide, acid, iodine values, dielectric constant, and fatty acid composition of the oils extracted from the samples were determined regularly. The oxidative stability of the extracted oils and storage stability of the samples were estimated from the results of the determinations. ${\alpha}-tocopherol$ did not exert any appreciable antioxidant effect on the extracted oil while BHA demonstrated some effect. Ascorbyl palmitate with citric acid and especially TBHQ exerted a considerable effect. The storage stability of the samples fried with the oil fortified with TBHQ was as good as that of the samples prepared with the palm oil. The stability of the samples improved as the palm oil content In the frying oil increased. The stability of the samples fried with the blended oil containing 70f) palm oil was comparable to that of the samples prepared with the pure palm oil

  • 최근 초등학생들은 간식은 물론 끼니를 위해서 스스로 식품이나 음식을 선택하고 구매하는 식생활 관리의 주체자가 되고 있다. 본 연구는 초등학생의 간식구매실태와 이에 영향을 미치는 식생태적 요인을 파악하고자, 서울과 충청남도의 대도시, 소도시 및 농촌의 4개 지역의 초등학생 4, 5, 6학년 총 431명(남 223, 여 208)과 그 학부모를 대상으로 간식섭취, PC와 TV 이용도, 학부모의 영양지식과 식태도, 간식구매빈도 등을 설문지 조사를 하였다. 조사대상 초등학생의 평균 신장과 체중은 교육부의 학생 신체검사 결과보다 약간 높거나 비슷하였으나, 조사대상의 30.6%가 저체중이고 10.8%가 비만이었다. 가정의 월 소득은 101-200만원이 가장 많았고(56.3%), 아버지는 대졸 이상이 59.7%, 어머니는 고졸 이상이 55.9%로 가장 많았으며, 어머니는 44.1%가 직업을 갖고 있었다. 학생의 월 용돈은 2,001-5,000원이 31.0%로 가장 많았으며 간식 비는 1일에 500원 미만이 46.0%로 가장 많았다. 간식섭취 빈도는 1일에 1번 섭취가 51.5%로 가장 많았고 간식 구매 시 고려사항은 맛, 가격, 영양가와 유통기한의 순 이었다. 조사대상의 46.9%가 PC통신 또는 인터넷을 사용하였고 사용시간은 1시간 미만이 53.8%로 가장 많았으며, 하루 평균 TV 시청시간은 2~4시간미만이 46.4%로 가장 많았다. 학부모의 평균 영양지식 점수는 13개 문항 중 8.16 $\pm$ 2.16으로서 평균 62.8%의 정답 율을 보였으며, 식 태도 점수는 총 50점 만점에 전체 평균이 43.22$\pm$4.04로서 비교적 양호하였다. 식품별 구매빈도를 보면 1주에 1회 이상으로 나타난 것은 우유, 과자류, 빙과류, 라면, 주스 및 껌의 순 이었고, 햄버거, 피자, 호떡은 한 달에 1회 또는 그 이하로서 가장 낮았다. 과자, 라면, 빙과류의 구매빈도는 가정수입과 아버지와 어머니의 교육수준과 음의 상관 관계를, 학생의 월 용돈, TV 시청시간 및 간식섭취 빈도가 높을수록 와는 양의 상관관계를 보였다. 라면과 탄산음료는 부모의 영양지식이나 식 태도와 음의 상관관계를 나타냈고, 햄버거 구매빈도는 가정수입과 아버지와 어머니의 교육수준이 높을수록 잦았다. 학생의 간식빈도가 높을수록 우유섭취빈도는 낮았으며, 과자, 빙과, 사탕, 닭 꼬치, 감자튀김, 돈까스, 튀김의 구매빈도가 증가하여 간식내용이 영양적으로 양호하지 않음을 알 수 있다. 또한 TV 시청시간이 길수록 간식빈도와 유사한 구매 양상을 나타냈다. PC이용시간이 길수록 과자와 빵의 구매빈도가 낮아지고 껌의 구매빈도가 높아져 흥미롭다. 결론적으로 조사대상 초등학생은 간식 구매시 영양가보다는 맛을 중요시하며, 우유를 제외하면 주로 탄수화물과 당류식품의 구매빈도가 높다. 또한 가정 소득, 부모 교육수준과 영양지식, TV시청시간, 학생의 간식 비와 간식빈도 등 환경요인들이 식품구매에 영향을 주었다. 따라서 영양사를 중심으로 간식 선택의 중요성과 식품 구매 원칙에 대한 체계적인 영양교육을 학생과 아울러 학부모에게도 실시하여 초등학생의 바른 간식 구매능력을 향상시켜야 할 것이다.

  • The physicochemical properties, antioxidant activity, color value, sensory evaluation, and sinigrin content of chicken breast jerky supplemented with Dolsan leaf mustard powder (DLMP) were evaluated over a period of 120 days. The control groups contained no DLMP, and the product groups contained 0.04 g (S-1, S-3) and 0.3 g (S-2, S-4) of DLMP. These samples were stored at 25℃ and 60℃ and then compared. The pH changes decreased at 25℃ and 60℃ over the storage period, with S-1 maintaining the highest pH value over the course of the experiment. The acid and peroxide values increased at room temperature and 60℃ but were better controlled in the DLMP-containing groups. Overall, the antioxidant activity of these products decreased during storage; the most marked reduction was observed in the control group, and the greatest activity was retained in S-2 and S-4. Hardness and gumminess were higher in the S-2 and S-4 groups and thus correlated with increased DLMP concentration. Sinigrin content also increased with increasing DLMP concentration. Product color remained similar at days 0 and 120 but underwent daily fluctuations over the course of the 120-day storage period. Sensory evaluation scores for color, flavor, taste, texture, and overall acceptability were highest for the S-2 and S-4 groups stored at 25℃. This suggests that higher concentrations of DLMP were more effective at retaining good quality characteristics for fried chicken breast jerky. This was facilitated by its suppression, which decreased changes in textural and color properties while increasing the antioxidant activity of these products.

  • This study aimed to investigate the acrylamide content in frozen food products after cooking. Twenty samples of bread (Group 1) and 30 samples of processed tuberous and corn vegetable products (Group 2) were selected. Acrylamide levels were quantified using liquid chromatography tandem-mass spectrometry (LC-MS/MS). The frozen food samples were heated using the air fryer cooking method according to the product packaging and were compared to ready-to-eat French fries (Group 3). The results showed that the acrylamide content was the highest in group 3, followed by that in group 2 and group 1. The acrylamide content of all the samples was found to be within the domestic recommended standard of 1 mg/kg. However, when the samples that exceeded EU benchmark level (0.5 mg/kg) were selected and cooked using the deep-fat frying method according to the product packaging, one of them showed the acrylamide content of 1.83 mg/kg, which exceeded the domestic recommended standard. The present study highlights the need for continued evaluation and management to reduce acrylamide contents in frozen foods, as increasing domestic exposure to acrylamide is concerning.

  • The effect of heated oil on human nutrition has recently become of great interest to nutritionists and food chemists. However, the detrimental effect of heated oil has been hardly studied extensively and many problems have still remained unsolved. This study was carried out to investigate the storage stability of the heated oils at room temperature (25$\pm$5$^{\circ}C$), with the variation in storage conditions (addition of spices and herbs) for 7 weeks period. The rancidity of the oils according to storage time and condition was measured and compared with TBA, ferric thiocyanate, and DPPH method. For fresh oil, when stored for 7 weeks at room temperature, her was no significant change in the degree of oxidation. But for the heated oil with frying materials, the degree of oxidation significantly increased at 5 weeks(p<0.05). When stored with spices and herbs, the degree of oxidation significantly decreased with storage period(p<0.05). Antioxidative activity of herbs, especially sage group was higher than that of any other group.

  • Chemical characteristics of soybean oil after deep-frying with potato sticks (200 g, 10% w/w of soybean oil) were studied according to the 34 deep-frying times. After consecutive 34 deep-frying, total polyunsaturated FA contents was gradually decreased while the total saturated FA and trans FA were increased. Acid value and peroxide value were increased while iodine value decreased, respectively. The Hunter $L^{\ast}$ value decreased while each $a^{\ast}\;and \;b^{\ast}b$ value were gradually increased. Electronic nose equipped with 12 metal oxide sensors was used for the discrimination of odor pattern of frying oils against the times of deep-trying. The proportions of 1st and 2nd principal component analysis showed 75.97% and 21.23%, respectively. While 6 among total 12 sensors well responded to discrimination of odor in the repented frying oils, suggesting that the odor pattern of each oil after deep-frying would be discriminated against fresh soybean oil, especially after 14 times. From the results, electronic nose could differentiate the degree of quality deterioration of the repeated deep-frying oils.
