박정숙,나환식,Park, Jung-Suk,Na, Hwan-Sik 한국식품영양과학회 2007 한국식품영양과학회지 Vol.36 No.2

영양학적, 생리학적 장점이 많은 표고버섯을 다양한 식품으로 이용하기 위한 적절한 가공방법을 모색하여 고부가가치를 갖는 식품으로 개발을 하고자 표고버섯을 첨가한 강정을 제조하여 첨가 수준별 품질특성을 조사하였다. 표고버섯 첨가 강정의 일반성분은 첨가량이 증가하면서 수분, 조단백질과 회분 함량은 증가하였고, 탄수화물 함량은 감소하였으며, 조지방은 차이를 보이지 않았다. 색도를 분석한 결과 L값은 대조구가 59.10로 가장 높았으며, 표고버섯 첨가량이 증가할수록 유의적으로 감소하였다. b값은 L값과 같은 경향을 보였으며, a값의 경우 증가하였다. 또한 모든 첨가구에서 대조구와 현저한 색의 차이를 보이는 것으로 나타났다. 강정의 물성 측정 결과 gumminess, brittleness, cohesiveness, springiness는 대조구와 20%, 30% 시료에서는 큰 차이를 보이지 않았으며, 40% 첨가구부터 그 값이 유의적으로 증가하였고, hardness의 경우 40% 첨가구까지 큰 차이를 보이지 않았다. 시료별 관능검사 결과는 색(color), 향미(flavor), 맛(taste), 바삭바삭한 정도(crispiness)와 전반적인 기호도(overall acceptability) 등 모든 검사 항목에서 30% 첨가구가 가장 높은 점수를 받았으며 40% 이상 첨가시 기호도가 조금씩 감소하는 것으로 나타났다. 쌀강정에 표고버섯을 일정 비율로 첨가하여 표고버섯 강정을 제조하고, 여러 특성을 조사한 결과 기존의 쌀강정에 비하여 표고버섯 첨가 강정이 더 우수한 제품이 될 수 있었고, 최적의 첨가량은 쌀 튀밥을 기준으로 30%로 나타났다. Gangjeong was prepared by adding Lentinus edodes to improve quality of the gangjeong and to give some functional properties. Contents of the crude protein and ash increased with increasing amount of L. edodes, while carbohydrate contents decreased. As the ratio of mushroom in gangjeong increased, lightness and yellowness in Hunter's color value tended to decrease. In terms of texture, 20% and 30% contents of L. edodes made no significant differences in gumminess, brittleness, cohesiveness, and springiness compared to control, whereas hardness showed no difference to control. Gangjeong with 30% L. edodes obtained the highest scores in quality and sensory characteristics.

Metformin is antihyperglycemic, not hypoglycemic. It causes neither insulin release from the pancreas nor hypo glycemia, even when taken in large doses. But, there are several reports of metformin-associated lactic acidosis (MALT). We present a case report of severe lactic acidosis most probably resulting from high doses of metformin in a patient with no known contraindications for metformin. A 43-year-old female was admitted to the emergency department due to a metformin overdose. She had diabetes for 6 years, well-controlled with metformin and novolet. One hour before admission, she impulsively took 50g metformin (100 mg or 100 tablets). Physical examination for symptoms revealed only irritability, and laboratory evaluation revealed only mild leukocytosis. After one hour the patient was drowsy, and arterial blood gas analysis showed severe lactic acidemia Seven hours after ED arrival, she commenced hemofiltration treatment and was admitted to the intensive care unit. Continuous venovenous hemodiafiltration was initiated. Forty-eight hours later, full clinical recovery was observed, with return to a normal serum lactate level. The patient was discharged from the intensive care unit on the third day. A progressive recovery was observed and she was discharged from the general word on the thirteenth day.

표고버섯 추출액을 이용한 조청의 품질특성

박정숙(Jung-Suk Park),나환식(Hwan-Sik Na) 한국식품영양과학회 2005 한국식품영양과학회지 Vol.34 No.7

건강식품으로서의 각광을 받고 있는 표고버섯을 이용하여 적절한 가공방법을 모색하여 고부가가치를 갖는 식품으로 개발을 하고자 표고버섯 추출액을 첨가하여 조청을 제조하고 여러 가지 실험을 행한 결과 다음과 같은 결과를 얻었다. 표고버섯 추출액을 당화액에 일정 비율로 첨가하여 졸이기를 한 조청의 일반성분은 조단백질, 회분과 조지방 함량은 거의 변화가 없었으며, 탄수화물 함량은 감소하였다. 무기성분의 경우 무첨가구가 2,642.34 ㎎/㎏, 추출액을 7 : 3의 비율로 첨가한 첨가구가 1,916.03 ㎎/㎏, 5 : 5 첨가구는 2,674.24 ㎎/㎏, 3 : 7 첨가구가 2,558.35 ㎎/㎏으로 버섯 추출액 첨가량에 따른 변화는 관찰할 수 없었다. 시료별 유리당 함량은 maltose>glucose>fructose 순으로 분석되었으며 표고버섯 추출액의 첨가 수준이 높아질수록 유리당 함량은 증가하였고, 아미노산 분석 결과 총 17종의 아미노산이 검출되었는데, 가장 많이 함유된 아미노산은 glutamic acid이었으며, 그 외 성분은 함량이 조금씩 차이를 보였다. 조청의 지방산 조성은 무첨가구의 경우 linoleic acid가 23.8%로 가장 높은 비율을 차지하였고, palmitic acid(22.3%), oleic acid(19.0%), myristic acid(14.2%)와 caproic acid(9.4%) 순이었으며 버섯 추출액을 첨가한 시료의 경우 그 양상이 다양하게 분석되었으며, 포화지방산(SFA)과 불포화지방산(USFA)의 비율도 변화가 없었다. 조청의 pH를 측정한 결과 5.5~5.7로 시료간 차이를 보이지 않았으며, 환원당의 경우 무첨가구가 40.38%, 당화액과 추출액의 혼합비가 7 : 3인 시료는 39.94%, 5 : 5 첨가구는 39.16%, 3 : 7 첨가구의 경우 44.70%로 나타나 무첨가구에 비해 큰 차이를 보이지 않았으며, 단지 3 : 7 첨가구만이 다소 높은 결과를 보였다. 또한 점도와 고형분 함량은 무첨가구가 각각 132×10³ cps와 74.32%, 당화액과 추출액의 혼합비가 7 : 3인 첨가구가 27.6×10³ cps와 64.96%, 5 : 5 첨가구가 25.6×10³ cps와 60.90%, 3 : 7 첨가구가 각각 21.9×10³ cps와 55.19%로 첨가량이 증가하면서 두 항목 모두 크게 감소하는 결과를 보였다. 색도를 분석한 결과 L값, a값, b값 모두 표고버섯 분말 함량이 증가하면서 감소하였고, 모든 처리구에서 기존 무첨가구와 극히 현저한 차이를 보이는 것으로 나타났다. 시료별 관능검사 결과에서 색(color), 먹을때의 느낌(chewiness)과 단맛(sweetness)의 경우 무첨가구와 모든 처리구가 유의적인 차이를 보였으며, 향미(flavor)와 전반적인 기호도(overall acceptability)에서 당화액과 추출액의 혼합비가 7 : 3인 시료구만이 무첨가구와 유의적인 차이를 보이지 않았다. 이러한 결과로 보아 표고버섯 추출액을 당화액에 첨가하여 조청을 제조할 경우 적정 첨가 수준으로 당화액과 추출액의 비가 3 : 7의 범위를 넘지 않아야 버섯의 장점을 살리면서 기존 조청의 특성을 변화시키지 않는 제품을 제조할 수 있을 것으로 보인다. Jocheong was prepared by adding Lentinus edodes extract to improve its quality and to give some functional properties. Contents of crude protein, ash and crude lipid were similar to those of control, while carbohydrate content was decreased. Total mineral content were 1,916.03~2,674.24 ㎎/㎏ that was no difference between test samples. From HPLC determination of free sugars, Jocheong was found to contain maltose as the highest sugar, followed by glucose and fructose. In amino acid analysis, seventeen amino acid were identified and quantified. Glutamic acid in Jocheong was major amino acid. The major fatty acids in Jocheong (0%, control) were linoleic acid, palmitic acid, oleic acid, myristic acid and caproic acid. There was no significant differences in fatty acid composition, pH and reducing sugar content among the Jocheong samples. The viscosity and solid contents tended to decrease with the addition of Lentinus edodes extract. Increasing the ratio of mushroom extract in Jocheong tended to decrease the lightness, yellowness and redness in Hunter's color value. Although sensory value decreased with increasing Lentinus edodes extracts, use of mushroom extracts (7 : 3; saccharification liquids : Lentinus edodes extracts) is recommended for making Jocheong.

Peppermint ( Mentha piperita L. ) belongs to a member of the mint family (Lamiaceae) and is widely used in food, cosmetics and medicines. This study was carried to investigate the variation of essential oil content and its composition during callus subculture of M. piperita. For callus induction from the leaf explant of peppermint, the basal medium was supplemented with various concentrations of 2, 4-D. The best callus induction rate (93%) of M. piperita. was obtained in MS medium containing 2 ㎎/l 2, 4-D. The induced peppermint callus maintained on Lin-Staba medium were studied during a period of 20th subcultures for the stability of essential oil production. Growth rates of peppermint callus increased during prolonged subculture. However, there was a progressive decrease of essential oil content and unstability of monoterpene productions when callus cultures were serially subcultured.
