오디 과실을 이용한 고부가가치의 가공식품의 개발에 관한 연구 일환으로 먼저 최소가공기술을 이용한 오디 과실주스 제조 방법을 조사하였다. 오디 과실의 물추출액을 면포여과, 감압여과(Whatman No. 4 filter paper를 이용한) 및 원심분리를 각각 실시한 결과 원심분리가 가장 좋은 청징효과를 나타내었다. 그리고 여러 여과보조제 및 청징제를 첨가한 후 원심분리하여 얻은 오디 과실즙의 색의 변화는 처리한 여과보조제, 청징제 및 청징 효소의 종류에 따라 차이가 있었으며, 특히 casein, gelatin, chitin, chitosan 및 PVPP는 오디 색소를 강하게 흡착하였으며, 그리고 청징효소 중 ${\alpha}-amylase$ 처리구가 가장 좋은 청징효과를 나타내었다. 다음, 오디 과즙을 원심분리한 후 $0.01\;{\mu}m$ 막여과를 실시한 결과 오디주스의 청징효과가 매우 우수하였으나 한외여과방법은 오디 색소의 강한 흡착으로 적절하지 않았다. 한편, 4가지 갈변저해제 처리에 따른 오디 과실주스의 갈변억제 효과를 측정한 결과 200ppm sodium hydrosulfite 처리구가 가장 갈변억제 효과가 우수하였으며, 아울러 0.1% L-ascorbic acid(L-AsA) 및 citric acid(CA)도 갈변억제 효과가 있었다. 그리고 위의 3가지 갈변저해제를 2중 복합병행 처리한 결과 0.1% L-AsA+0.1% CA 처리구가 가장 좋은 갈변억제 효과를 나타내었다. 마지막으로 관능검사를 실시한 결과 오디주스의 최적 당/산비는 40-50이었으며, 또한 상업적 살균 온도($85-90^{\circ}C$)에서 처리시간은 10분이 가장 적합함을 알 수 있었다.

본 연구는 뽕나무 열매 착즙 분말 (MJ)이 지방세포 분화과정에서 염증에 관여하는 유전자 발현 및 miR-132/143 조절에 미치는 효과에 중점을 두고 조사하였다. MJ는 3T3-L1 지방세포 분화 동안 지질축적이 억제되었고 PPAR-γ, CEBP-α 및 aP2와 같은 지방형성 유전자 발현을 억제하였다. 또한 염증 조절 매개체인 TNF-α, IL-6, MCP-1 및 iNOS 유전자 발현이 MJ 처리에 의해 감소되었다. MJ의 지질 축적 억제 효과는 염증과 지방분화에 관여하는 miR-132/143의 발현 감소와 관련이 있음을 확인하였다. 따라서 MJ는 염증을 동반하는 비만 예방 및 치료에 도움이 될 수 있는 식품 소재로서 가능성이 있음을 시사하고 있다. 그러나 MJ의 주요 성분인 안토시아닌의 생체이용율은 1-2% 미만으로 추정되며 예상되는 표적 조직이나 혈류에서 미량 검출되는 것으로 알려져 있다 [33]. 이를 해결하기 위해서는 생체 내 동물실험을 통한 다각적인 분석이 향후 진행되어야 할 것으로 판단된다.

This study was carried out to investigate of the quality characteristics of the starch Oddi Dasik(MSOD) manufactured with various addition levels (0, 5, 10, 18 and 28%) of mulberry fruit (Oddi) juice (MFJ), with various levels(55%, 50%, 45%, 37% and 27%) of sucrose syrup, and with the ratio of rice powder: mungbean starch (1:4) according to the traditional Korean Dasik (a kinds of cookie) methodology. The nutritional components of Oddi and MSOD were examined, and sensory evaluation and physical tests of MSOD added MFJ were conducted. The results are summarized as follows. In Oddi, the contents of moisture, crude fat, crude protein, crude ash, and vitamin C, and the levels of acidity, pH and sugar were 88.45%, 0.245%, 2.23%, 0.88%, 53.20 mg%, 8.00%, 4.41 and 11.0 Brix%, respectively. In MSOD (Oddi 10%), the contents of moisture, crude fat, crude protein, and crude ash, were 22.8%, 0.117%, 9.2% and 0.8%, respectively, and were all increased with increasing MFJ amount. In MSOD (Oddi 10%), the contents of Ca, Mg, K and Fe were 63.2 mg%, 70.9 mg%, 376.0 mg% and 7.7 mg%, respectively. and were increased with increasing MFJ amount. For the establishment of the additional amount of MFJ, sensory evaluation and physical tests were conducted. From the total characteristics of sensory evaluation, the MSOD with 10% MFJ was judged as the best. Color L and b values of MSOD significantly decreased and a value increased with increasing MFJ percentage. Hardness, gumminess, adhesiveness and chewiness among the texture characteristics of MSOD were significantly increased with increasing MFJ amount. However, there were no significant differences in springiness and cohesiveness of the MSOD. In conclusion, the optimal added amount of MFJ for the manufacture of the MSOD was proposed to be 10% of the total weight.

This study investigated the effect of added freeze-dried mulberry fruit juice (FDMJ) (1, 3 and 5%) on the antioxidant activity and fermented characteristic of yogurt during refrigerated storage. A decrease in pH of yogurt and increase in acidity was observed during fermentation. The yogurts with FDMJ exhibited faster rate of pH reduction than control. Initial lactic acid bacteria count of yogurt was 6.49-6.94 Log CFU/g and increased above 9 Log CFU/g in control and 1% in FDMJ yogurt for 24 h. The total polyphenol and anthocyanin content of FDMJ yogurt was higher than that of control due to the presence of phytochemical contents in mulberry. Moreover, antioxidant activity such as DPPH and reducing power was highest 5% FDMJ yogurt. During cold storage, pH decreased or remained constant in all yogurts with values ranging from 4.08 to 4.78 units. In sensory evaluation, the score of 1% FDMJ yogurt was ranked higher when compared with other yogurts. It is proposed that mulberry fruit juice powder can be used to improve sensory evaluation and enhance functionality of yogurt.

For this study, we designed and produced mulberry low-fat ice cream supplemented with synbiotics (MLF-ISS). The sensory characteristics and physical, chemical, and microbiological qualities of MLF-ISS were then determined. Mulberry juice inoculated with or without probiotic (Lactobacillus plantarum TISTR 926 and Saccharomyces boulardii CNCM I-745) was also tested at 37℃ for 24 h to determine probiotic growth rate, pH, total anthocyanin content (TAC), total phenolic content (TPC), and antioxidant activity (AA). Only the TAC of mulberry juice inoculated with S. boulardii CNCM I-745 increased considerably (p < 0.05) among these parameters. MLF-ISS was produced with varied mulberry fruit concentrations (0, 10, 20, 30, or 40%) (w/w). The MLF-ISS prepared with 30% mulberry fruit (w/w) (30-MLF-ISS) had a higher score in appearance, color, and sweetness (p < 0.05) when sensory qualities were measured using the 9-point hedonic scale method. In the CIE lab system (L^*, a^*, b^*), the color values of 30-MLF-ISS were 27.80 ± 0.26, 12.99 ± 0.59, and 1.43 ± 0.05, respectively. The 30-MLF-ISS was also subjected to a proximate analysis. The melting rate of 30-MLF-ISS was 0.29 ± 0.03 g/min and the time it took for the first drop to fall was 37.00 ± 7.00 min. TAC, TPC, and AA of 30-MLF-ISS were observed to alter significantly (p < 0.05) during varied intervals of storage at - 18℃ (0, 30, and 60 days). The viability of probiotics in 30-MLF-ISS slightly decreased after storage at -18℃ for 8 weeks, but remained about 6 log CFU/g. During storage at -18℃ for 0 and 120 days, no pathogenic bacteria were detected in 30-MLF-ISS. These findings show that 30-MLF-ISS has nutritional and functional value, is free of foodborne pathogenic bacteria, is safe for consumers' health, and is suitable for application in the ice cream and related food industries.

Morinda citrifolia, also known as Great Morinda, Indian Mulberry, or Noni, is a plant belonging to the family Rubiaceae. A number of major chemical compounds have been identified in the leaves, roots, and fruits of the Noni plant. The fruit juice is in high demand in alternative medicine for different kinds for illnesses such as arthritis, diabetes, high blood pressure, muscle ached and pains, menstrual difficulties, headache, heart diseases, AIDS, gastric ulcer, sprains, mental depression, senility, poor digestion, arteriosclerosis, blood vessel problems, and drug addiction. Several studies have also demonstrated anti-inflammatory, antioxidant and apoptosis-inducing effects of Noni in various cancers. Based on a toxicological assessment, Noni juice was considered as safe. Though a large number of in vitro, and, to a certain extent, in vivo studies demonstrated a range of potentially beneficial effects, clinical data are essentially lacking. To what extent the findings from experimental pharmacological studies are of potential clinical relevance is not clear at present and this question needs to be explored in detail before an recommendations can be made.

꾸지뽕 열매의 부가가치를 증대하기 위해 꾸지뽕 발효식초를 제조하고 그의 발효조건을 확립하였다. 전통발효식품으로부터 초산내성, 초산 고생산능, ethanol 내성 및 아황산 내성이 우수한 49종의 초산 균주를 분리하였고, 16S rRNA 유전자 염기서열의 해독 결과, Acetobacter indonesiensis, A. cerevisiae, A. orientalis, A. tropicalis, A. fabarum, A. pasteurianus 및 A. syzygii으로 동정되었다. 이들 중 GRAS 균주인 A. pasteurianus SCMA5와 SCMA6를 발효 균주로 최종 선정하였다. 최적 발효는 꾸지뽕 열매 함량이 40%(v/v)인 즙액과 5%(v/v) ethanol을 첨가하여 $25^{\circ}C$에서 72시간 발효가 가장 적절하였다. 관능평가 결과, SCMA06 균주를 적용한 발효액의 선호도가 SCMA05 균주를 적용한 발효액보다 높았다. SCMA06 균주를 사용한 발효식초에서 항산화 능력을 측정하는 DPPH 라디컬 소거활성의 경우 대조구에 비해 $53.02{\pm}0.78%$이상 높게 나타났고, 항당뇨 능력을 측정하는 AGI활성은 발효 72시간에 $91.40{\pm}2.43%$ 저해능을 보여 시판중인 acarbose보다 활성이 높았다. 이번 연구는 꾸지뽕 열매를 활용한 발효식초 제조를 위한 산업화 연구에 기여할 수 있을 것이다.
