  • Sugar snap cookies were prepared with the addition of carrot powder (2~12%) as a source of dietary fiber. Analyses of physiochemical properties, rheology and sensory evaluation of the cookies were conducted. Increasing carrot powder content weakened the flour, as evidenced by decreased diameter and increased thickness, which resulted in decreased spread factor. The water content of the carrot powder-amended cookies and unamended flour was not significantly different. The pH and L values progressively decreased and a and b values progressively increased with increasing addition of carrot powder. Textural analysis revealed no significant differences in brittleness with carrot powder addition, even though brittleness did decrease with the addition of more carrot powder. Sensory evaluation revealed a preference for cookies prepared with 2~4% carrot powder, with decreased preference at powder concentrations exceeding 6%. Addition of a dried vegetable with high fiber content caused the dietary fiber to absorb much water content, resulting in decreased diameter, increased thickness and decreased spread factor. Therefore, it is deemed desirable to increase the spread factor by controlling the water content and adding emulsifiers so as to enhance the functionality and maintain the quality of cookies.

  • In this study, optimized pre-treatment conditions were investigated to improve the quality of gochujang apple jangachi. The moisture content was decreased by 14% in 60% sugar solution and 17% in 30% salt solution during 12 hours. On the one hand, in the case of dry sugar and salt method, moisture content was decreased rapidly by 20% and 24%, respectively during 12 hours. Compared with the sugar and salt solution method, the dry sugar and salt method was more effective in reducing moisture content during 12 hours. In the case of osmotic dehydration of the apple parts in the dry sugar method, the moisture content of the flesh, flesh including peel, and peel of apple decreased by 23%, 20%, and 16%, respectively during 6 hours. However, in the dry salt method, the moisture content of the flesh, flesh including peel, and peel of apple decreased by 19%, 12% and 13%, respectively during 2 hours. During this time, the pH tended to decrease, regardless of the presence of sugar and salt. Total acidity was slightly increased in the case of salt. In hot air drying after osmotic dehydration, the moisture content of flesh including peel of apple decreased from 64% and 67% to 31% and 27%, respectively at 90 minutes, and from 64% and 67% to 11% and 18% at 150 minutes, respectively. The moisture content of the peel decreased from 51% to 10% at 120 minutes. As a result of the sensory evaluation, the overall acceptance of the flesh and flesh including peel was highly evaluated, resultantly, the products were considered to be suitable for the production of gochujang apple jangachi.

  • Influence of garlic on the quality characteristics of apple jam was investigated. Apple jams with various amounts of sugar and garlic were prepared, and their sweetness, color difference, and instrumental texture were evaluated. The results were as follows: 1. When equal amount of sugar was added, the sweetness of apple jam decreased as the garlic content increased. 2. As the garlic content increased, the lightness and yellowness tended to be high and the redness and ΔE tended to be low, resulting that the color of apple jam was improved. 3. As the sugar content increased, the hardness and adhesiveness of the jam tended to increase when garlic was added at 10%. 4. Apple jam with 60% sugar and 10% garlic was the best in adhesiveness, glossiness, and overall quality by sensory evaluation. As the addition of garlic did not cause any significant difference in flavor, cooked garlic could be applied in apple jams.

  • Recently, due to the cognition that obesity is the cause of adult diseases, interests of consumers in low-sugar and low-calorie foods are growing more and more. While various policies are being implemented to reduce sugar contents in processed foods, the reduced sweetness caused by lesser sugar content is complemented by using high-intensity sweeteners. Some of the typical high-intensity sweeteners are sucralose, aspartame, acesulfame potassium and stevia, etc. Since the relative sweetness degree, sweetness profile, and physical properties of these sweeteners should be different from one another, it is important that all these characteristics are well-understood before applying them. Thus, the objective of this study is to introduce the properties and applications of high-intensity sweeteners in order to reduce sugar content of processed foods.

  • For waxy corn hybrid development, 23 waxy corn hybrids were planted and surveyed in both pericarp thickness and sugar content. Pericarp thickness showed average 50 to $49{\mu}m$ in field and greenhouse. Results like these advanced than previous other hybrids. Also, sugar content in developed waxy corn evaluated as 13.6 to 15.3 brix. Here, we concluded that edible quality of waxy corn depended on combing of two factors. Especially, CNU11H8 hybrid at field and CNU11H-38 at greenhouse were good in both factors. Accordingly, these hybrids will be planted in next time for productivity and area adaptation.

  • The present study has been performed to select the osmotic tolerant lines using polyethylene glycol (PEG 6000) through an in vitro and in vivo mutagensis with a gamma-ray. During the screening, we selected three mutant lines that seemed to confer elevated osmotic tolerance in high concentrations of PEG 6000. Fruits of these mutants (Os-HK101, Os-HK102 and Os-HK103) were increased to sugar concentration, L-glutamine acid, vitamin C content and lycopine content than those of the wild type. Also the chlorophyll contents were few decreased more in the three mutant lines than the WT plants. Our results suggest that the Os-HK101 is characterized as osmotic stress tolerance considering the sugar concentration and lycopine content. It is expected that the result of this study can be used for breeding more competitive species with respect to contents in sugar or functional chemicals from the selected osmotic resistant lines.

  • 본 연구에서는 대전과 충남북 지역에서 지역별로 8개의 학교를 선정하고 각 학교당 4주간의 급식을 수거하여 842개 메뉴의 당 함량을 분석하였고, 수거된 급식메뉴에 대해 초등학교 2학년과 5학년, 중학교 2학년 남녀학생의 급식섭취량을 직접 측정하여 급식을 통한 2,806건의 당 섭취량을 산출함으로써 해당학교 및 지역의 당 섭취 특성을 대표할 수 있는 자료를 확보하였다. Fructose, glucose, sucrose, maltose, lactose의 함량 합으로 구한 총 당류의 함량은 가공식품에서와 달리 학교별로 임의의 조리법에 의해 조리된 음식이므로 그 범위가 넓게 나타났다. 주식류의 당 함량은 급식 100 g당 평균 0.20 g, 부식류는 2.08 g, 후식류는 5.13 g으로 과일음료와 유제품, 과일 등을 포함한 후식류의 당 함량이 다른 군에 비해 훨씬 높은 것으로 나타났으며, 부식류 중에서는 소스류와 조림류의 당 함량이 높았다. 급식메뉴 중 가장 많은 양을 섭취하는 음식은 일품식류, 음료 및 차류, 탕 및 전골류, 찌개류 순이었으며, 주스나 식혜와 같은 음료는 정해진 규격이 있어 다른 부식류에 비해 섭취량이 높게 나타났다. 부식류중에서는 국 종류를 제외하면 30~50 g 범위에서 찜류, 튀김류, 볶음류, 부침류, 조림류, 구이류 순으로 많이 섭취하였으나 무침.나물류와 김치류는 각각 13 g, 10 g만을 섭취하였다. 급식메뉴 중 후식류, 특히 음료 및 차류, 유제품류섭취로 인한 당 섭취량이 가장 많았으며 이들 식품은 당 함량도 높고 규격화된 중량으로 인해 섭취량도 많았기 때문이다. 일품식류는 낮은 당 함량에 비해 급식섭취량이 많아 후식류 다음으로 당 섭취에 크게 기여하였으며, 부식류에서도 조림류에 비해 당 함량이 낮은 튀김류의 급식섭취량이 많으므로 튀김류로 인한 당 섭취량이 조림류로 인한 것보다 높게 나타났다. 급식 한 끼니를 통한 당 섭취량은 평균 4.22 g으로, 학년이 높을수록 급식섭취량과 함께 끼니당 당의 섭취량도 많아 중학생이 5.31 g, 초등학생이 4.03 g을 섭취하였으며, 성별이나 수거시기에 의한 차이는 크지 않았다. 학교급식을 통한 한 끼니의 당 섭취량은 열량섭취량을 기준으로 정한 한국인 총 당류 섭취기준이나 한국인영양조사 결과의 하루 총 당류 섭취량의 10분의 1 이하 수준으로, 한 끼니 해당량으로서도 높지 않은 것으로 판단된다. 다만 과일주스, 식혜 등의 음료나 요구르트 등의 당 함량이 높은 식품이 제공되거나 이러한 후식류가 일품식류와 함께 제공되어 한 끼니당 당의 섭취량이 높은 급식일이 없도록 하는 데에는 관심을 가질 필요가 있을 것으로 판단된다.

  • The purpose of this study was to analyze the amount of sugar from the afternoon snack menu of childcare facilities in Gyeongsangbuk-do. The amount of sugar was analyzed for afternoon snacks provided by childcare facilities between March and April 2016. The snacks provided were the same for processed and non-processed foods at 50.0% respectively. White milk accounted for the largest portion with 26.4%, followed by fruits with 19.9% and grains (sweet potatoes, rice cakes, etc.). It has been confirmed that the larger the facility, the lower the frequency of provision of non-processed foods, and the higher the provision of processed foods (p<0.05). Snacks served as non-processed foods showed the highest frequency of fruits and sweet potatoes. On the other hand, processed foods provided many sugar-rich products, such as liquid yogurt, hot cakes, and cereal, excluding white milk. The average sugar content was highest in processed milk products (13.9 g), followed by white milk (8.6 g), bread and snacks (8.0 g), other (4.6 g), and mixed grains (1.6 g). Of the total 216 snacks, banana flavored milk had the highest sugar content of 27.0 g, followed by strawberry milk (15.0 g) and castella (21.6 g). The findings are expected to be used as basic data for choosing the right snacks provided by childcare facilities and practicing reducing sugar intake.

  • The objective of this study was to investigate the effects of replacing sucrose with sugar alcohols (sorbitol, glycerol and xylitol) on the quality properties of semi-dried jerky. Total 7 treatments of jerkies were prepared as follows: control with sucrose, and treatments with 2.5 and 5.0% of sucrose replaced by each sugar alcohol, respectively. Drying yield, pH, water activity, moisture content, shear force, myofibrillar fragmentation index (MFI), 2-thiobarbituric acid reactive substance (TBARS) value, sugar content, and sensory evaluation were evaluated. Xylitol slightly decreased the pH when compared to the other sugar alcohols (p>0.05). The water activity of the semi-dried jerky was significantly reduced by treatment with glycerol and xylitol (p<0.05). The moisture content of semi-dried jerky containing various sugar alcohols was significantly higher than that of the control (p<0.05), while replacing sucrose with glycerol yielded the highest moisture content. The shear force of semi-dried jerky containing sugar alcohols was not significantly different for the sorbitol and glycerol treatments, but that replacing sucrose with 5.0% xylitol demonstrated the lowest shear force (p<0.05). The TBARS values of semi-dried jerkies with sugar alcohols were lower than the control (p<0.05). The sugar content of the semi-dried jerkies containing sorbitol and glycerol were lower than the control and xylitol treatment (p<0.05). In comparison with the control, the 5.0% xylitol treatment was found to be significantly different in the sensory evaluation (p<0.05). In conclusion, semi-dried jerky made by replacement with sugar alcohols improved the quality characteristics, while xylitol has applicability in manufacturing meat products.
