This study was conducted to investigate the growth and antioxidant activity of Pleurotus ostreatus mycelia grown in medium supplemented with Aronia. The diameter and dry weight of the mycelia were increased in the medium supplemented with Aronia compared with the untreated medium. The total polyphenol content of mycelia grown in medium supplemented with Aronia and untreated medium was 6.54 mg GAE/g and 5.77 mg GAE/g, respectively. The 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity of mycelia grown in medium supplemented with Aronia and untreated medium was 61.81% and 49.65%, respectively. Moreover, the 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activity of mycelia grown in medium supplemented with Aronia and untreated medium was 59.83% and 52.66%, respectively. These results confirmed that P. ostreatus mycelial growth and antioxidant activity were increased when Aronia was added to the culture medium.

뽕나무, 복분자, 블루베리의 전정 가지 대부분은 버려지고 있다. 따라서, 이들 버려지는 전정 가지를 활용하여 흰점박이꽃무지의 사육 가능 성을 검토하기 위하여 발육 및 산란 특성을 조사하였다. 베리류 발효톱밥을 먹인 흰점박이꽃무지 유충 발육 기간은 뽕나무 발효톱밥 157.3일, 복 분자 발효톱밥 130.3일, 블루베리 발효톱밥은 140일로 참나무 발효톱밥 169.3일에 비하여 짧아지고, 유충 무게가 증가하였으며, 생존율이 높았 다. 흰점박이꽃무지 유충 집단 사육시 2.5 g 이상인 유충 비율은 3종류의 발효톱밥 모두 6주에서 8주사이에 60% 이상인 반면 같은 기간에 참나무 발효톱밥은 10% 이내였고, 10주가 지나야 2.5 g 이상인 유충의 비율이 높아졌다. 흰점박이꽃무지의 평균 산란수는 80개 이상으로 평균 산란기 간은 9주정도 소요되었지만, 개체당 편차가 커서 유의차는 없었다. 3종류의 베리류 발효톱밥은 서로 혼합하여 사용해도 참나무 발효톱밥에 비해 유충 발육속도가 빠르고, 산란수는 차이가 없었다. 따라서, 흰점박이꽃무지를 사육하는데 있어서 베리류 발효톱밥이 참나무 발효톱밥에 비하여 효과적으로 추정된다.

장과류의 방사능 안전성 확보를 위해 2016년부터 2018년까지 경기도 내 유통 중인 장과류 및 가공식품 15품목 258건을 수거하여 방사능 오염을 분석하였다. 방사능 분석은 게르마늄 감마핵종 분석기를 이용하였으며, 인공 방사성 물질인 요오드(131I)와 세슘(134Cs, 137Cs)을 분석하였다. 모든 제품에서 131I와 134Cs은 MDA (Minimum Detectable Activity)값 이상으로 검출되지 않았고, 39건에서 0.69-808.90 Bq/kg 범위로 137Cs이 검출되었다. 국내산 제품 6건은 0.70- 3.29 Bq/kg 범위에서 검출되었지만, 원재료는 모두 수입산 이었다. 수입산 제품 33건은 0.69-808.90 Bq/kg 방사능 농도를 나타내었으며, 폴란드산 블루베리 분말 제품 1건(808.90 Bq/kg) 및 링곤베리 분말 제품 2건(103.93, 188.46 Bq/kg)은 국내 방사성 세슘의 허용 기준을 초과하였다. 이러한 결과는 식품 안전 확보를 위해 수입산 장과류와 장과류 가공식품에 대한 방사능 검사 강화와 함께 수입 과정에서 더 철저한 관리가 필요한 것으로 판단된다.

This study was conducted to evaluate the time required to sell Protaetia brevitarsis larvae when larvae fed on three kinds of fermented berries sawdust, such as mulberry, raspberry, and blueberry. The first instar larvae were reared in a plastic container(543x363x188mm) with designated feeds, and investigated the cumulative proportion of larvae more than 2.5g at rearing room regulated at 25±1℃ with 50~60% under 16:8(L:D). When we reared larvae for about 45 days with fermented blueberry sawdust, the cumulative proportion of larvae with more than 2.5g was over 70%. It was about 40 days shorter than fermented oak sawdust. For each group, the average survival rates of larvae at the possible time for sale were 72~93%.

Background : Haskap berries commonly refer to fruits of Lonicera caerulea L., recognized by the Japanese aborigines as the “The elixir of life.”. Due to their recent arrival on the North American market, haskap berries have not yet been positioned among other berries and compared in terms of their phytochemical content. And haskap berries have higher ascorbic acid and anthocyanin content than other berries known for their health-promoting benefits, such as blueberries. However, no study has reported on the antioxidant and anti-cancer activity of Lonicera caerulea stem. The purpose of this study is to present the current research on the chemical content, antioxidant and anti-cancer activities of Lonicera caerulea stem. Methods and Results : The stem of Lonicera caerulea L. ware dried in the shade at room temperature and extracted with 100% methanol. The extract was suspended in deionized water and partitioned sequentially with n-hexane, chloroform, ethyl-acetate and butanol (water saturated BuOH) fractions. Antioxidant activities were measured by determination of antioxidants, DPPH (2,2-diphenyl-1-picrylhydrazyl). Cell viability was determined by the MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide] assay. All cell lines were purchased from the Korean Cell Line Bank (Seoul, Korea). All results were performed with three replications were processed statistically. By DPPH assay, the Lonicera caerulea L. the highest activity was obtained from the ethyl-acetate fraction (IC50=15.46 ㎍/㎖). By MTT assay, the chloroform fraction showed a significant growth inhibiting effect on MCF-7 (Human breast cancer, IC50=225.91 ㎍/㎖), COLO 205 (Human colon cancer, IC50=179.55 ㎍/㎖), but on AGS (Human stomach cancer) and other fractions it did not show effect. Conclusion : We demonstrated that Lonicera caerulea L. stem extract and fractions has antioxidant and antiproliferation activity in vitro. Further studies should identify the active constituents in Lonicera caerulea L stem to evaluate the potential in vitro antioxidant and antiproliferation activities of the extract.

'Green King', a new green tetraploid table grape cultivar with large berries, was originated from a cross between ‘Tensyu’ and ‘Beni Fuji’ grape cultivar in 2000. The cultivar was preliminarily selected among the elite breeding lines for its superior growth characteristics in 2005. After an extensive three-year evaluation of fruit and tree characteristics as 'GWG2002-02', 'Green King' was finally selected in 2008. Under Chuncheon’s ecological conditions, the average harvest date for 'Green King' is 6 September, and the number of days from flowering to harvest is 88 days. Hence, it is 12 days shorter than 'Rosario Bianco'. The average weight of a cluster in 'Green King' is 379.6 g, and its yield is 1,852 kg/10a. It has larger fruit size and higher fruit productivity than ‘Rosario Bianco’ (Registration No. 3560).

Edible berries are rich in anthocyanins and phenolic acids, compounds that possess antioxidant, anti-inflam-matory, and other biological activities. Antioxidant and anti-inflammatory activities of five berries including acaiberry(Euterpe oleracea Mart.), Aronia/black chokeberry (Aronia melanocarpa), blueberry (Vaccinium angustifolium), black cur-rant (Ribes nigrum L.), and cranberry (Vaccinium macrocarpon) were assessed. The Aronia G (prepared by GreenField s.c.)exhibited the highest antioxidant activities as shown in total phenolic (138.81㎎ CAE/g), flavonoid (3.68㎎ QE/g), andanthocyanin (20.31㎎/g) contents compared to the other berries. It also showed the strongest scavenging activities such asDPPH (69.69㎎ vitamin C/g) and ABTS radical scavenging activity (757.79µmol trolox/g). Aronia G exhibited strong ferricreducing antioxidant power (553.98µmol vitamin C/g), and oxygen radical absorbance capacity (820.92µmol trolox/g). Inaddition, black currant and Aronia showed stronger inhibition of nitric oxide production in lipopolysaccharide-stimulatedRAW 264.7cell than the other berries. According to the above results, the Aronia and other edible berries have notably highlevel of antioxidant activities and they could be used as a potential source of natural antioxidants.

Wild grapes have been used as traditional medicinal use and alcoholic beverage production in Korea. The objective of this study is to improve antioxidant properties in Sae-muru by far infrared ray (FIR) treatment, with expecting potential benefits of FIR treatment for wild grape products during manufacturing processes. FIR treatment in berries induced increased content of catechin, epicatechin gallate, epigallocatechin gallate, gallic acid, rutin, ellagic acid, and resveratrol, while content of epicatechin and epigallocatechin was decreased. Although FIR treatment resulted either increased or decreased chemical component groups, presenting in HPLC chromatograms, antioxidant activity in Sae-muru extract was significantly increased by the FIR treatment. Our results suggest that FIR treatment should be an efficient process in the production of high content of bioactive molecules in Sae-muru.
