정인철,윤동화,문윤희 한국생명과학회 2007 생명과학회지 Vol.17 No.2

This study was carried out to investigate the effect of addition of red wine on the water holding capacity, surface color, pH, TBARS value, VBN content and total bacterial counts of pork patties during cold storage. Pork patties were prepared by four type such as pork patty without red wine (control), pork patty containing red wine 1% (RW-1), pork patty containing red wine 3% (RW-3) and pork patty containing red wine 5% (RW-5). The water holding capacity was increased significantly during cold storage, but was not influenced by addition of red wine (p<0.05). The L* (lightness), a* (redness) and b* (yellowness) value was low by addition of red wine, was decreased during cold storage (p<0.05). The pH of pork patties were tend to increased with increase in cold storage period, the pH of RW-3 and RW-5 were significantly lower compared to control and RW-1 (p<0.05). The TBARS value of pork patties were tend to increased with increase in cold storage period, by increasing the amount of addition of red wine, the TBARS value were tend to decreased (p<0.05). The VBN content and total bacterial counts of pork patties were tend to increased with increase in cold storage period, and by increasing the amount of addition of red wine, the VBN content and total bacterial counts were tend to decreased during cold storage. 본 연구는 적포도주의 첨가가 돈육 patty의 냉장 중 품질에 미치는 영향을 검토하기 위하여 적포도주를 첨가하지 않은 돈육 patty(대조구), 적포도주를 1% 첨가한 돈육 patty(RW-1), 적포도주를 3% 첨가한 돈육 patty(RW-3) 및 적포도주를 5% 첨가한 돈육 patty(RW-5) 등 네 종류의 돈육 patty를 제조하고, 냉장 중 보수력, 표면색깔, pH, TBARS값, VBN 함량 및 총균수를 측정하였다. 보수력은 냉장 중 현저하게 증가하였으나, 적포도주의 첨가에 의한 영향은 없었다(p<0.05). 돈육 patty의 L*, a* 및 b*값은 적포도주 첨가에 의하여 낮아졌으며, 냉장 중 감소하는 경향이었다(p<0.05). pH는 냉장 기간이 경과하면서 증가하는 경향이었으며, 적포도주를 3 및 5% 첨가한 돈육 patty가 대조구 및 적포도주 1% 첨가구보다 낮게 나타났다(p<0.05). TBARS값은 냉장 기간이 경과하면서 현저하게 증가하였으며, 적포도주 첨가량이 증가함에 따라 TBARS값은 감소하는 경향이었다(p<0.05). 돈육 patty의 VBN 함량은 냉장기간의 경과와 함께 유의하게 증가하였으며, 총균수도 냉장기간에 의하여 증가하였다. 그러나 적포도주의 첨가가 VBN 함량과 총균수의 증가를 억제하는 경향이었다.

This study was carried out to evaluate the basic characteristics of red wine processed from ‘Cheongsan (Vitis amurensis)’ grape cultivar. In order to compare the quality of ‘Cheongsan’ red wine, ‘Campbell Early’ and ‘Muscat Bailey A, MBA’ red wines were also utilized for this study. The pH of the red wines produced from ‘Cheongsan’, ‘Campbell Early’ and ‘MBA’ were 3.1, 3.6 and 4.0, respectively. Tannin, polyphenol, and anthocyanin contents of the ‘Cheongsan’ red wine were 2,939 mg/L, 1,516.2 mg/ L, and 1,882.4 mg/L, respectively. These values were about twice those of ‘Campbell Early’ and ‘MBA’ red wines. The antioxidant level of ‘Cheongsan’ red wine was found to be 5,413.9 mg/L, which was also two times higher than 'Campbell Early' and 'MBA' red wines. Although the acidity of ‘Cheongsan’ red wine is relatively high, ‘Cheongsan’ red wine contains a lot of tannin, matures over an extended period of time and has excellent antioxidant properties. These results indicated that 'Chengsan' grape could be an excellent source for production of high quality red wine.

Red wine has become very popular, in part for its professed health benefits. Anthocyanin pigments, which are the main components of the pigments in red wine, are changed in the molecular structures and the color with the solution having different alkalinity and metals. The color changes of a red wine soiled cloth after washing in various pHs and water hardness solutions were studied. Distilled and tap water, which have lower water hardness, showed the highest $L^*$ value and lowest $a^*$ and $b^*$ values at pH 9. The detergent with added oxygen bleach was more effective in removing red wine soil, even though its pH was 10.8. The effect of the red wine removal with the solution where bleach was added separately was much lower than with the solution of the detergent containing bleach. Water hardness greatly affected the color of the cloth, soiled with red wine after washing. That is, the color was the faintest when the cloth was washed with the bleach-added detergent solution having 0 ppm of water hardness. An effective and economical method or equipment for removing metals in a washing solution for a washing machine should be developed to enhance the stain and soil removal.

국내에서 시험재배한 양조용 적포도주 및 백포도주 포도품종에 대한 포도주 발효특성을 조사하였다. 사용한 포도품종은 적포도주용으로 Carbernet Sauvignon, NY 21576, Canner, SV 18315, Agawan, Black Bagal 등 6품종, 백포도주용으로 Naples, Aligote, Alicante 등 3품종을 사용하였다. 사용한 포도의 당도는 적포도주용의 경우 Carbernet Sauvignon 18.0°Bx, NY 21576 18.4°Bx, Canner 20.0°Bx, SV 18315 18.0°Bx, Agawan 17.0°Bx 그리고 Black Bagal 17.0°Bx이었으며 백포도주용의 경우 Naples 20.0°Bx Aligote 17.0°Bx 그리고 Alicante 17.0°Bx이었다. 각각의 포도의 초기 당도를 설탕을 첨가하여 21°Bx로 맞춘 후에 효모를 포도에 대하여 0.02% 접종하여 20℃에서 2주간 발효를 실시한 결과 알코올 발효 속도는 포도 품종에 관계없이 대개 비슷하였으나 Black Bagal과 Carbernet Sauvignon이 상대적으로 늦었고 백포도주의 경우 3가지 품종 비슷한 발효 속도를 나타냈다. 색도의 경우 적포도주의 경우 대부분의 품종이 국내산 캠벨에 비하여 진하였으며 Agawan과 NY 21576이 상대적으로 L 값이 낮고 색이 진하였다. 발효 2주일 후 포도주의 폴리페놀의 함량변화는 시료 중 NY21576이 1.40 ㎎/mL으로 가장 높았고 국내산 MBA 포도주가 0.55 ㎎/mL로 가장 낮았으며 백포도주는 품종에 관계없이 0.15 ㎎/mL 내외로 적포도주에 비하여 매우 낮게 나타났다. 관능검사결과 적포도주의 경우 NY 21576, Carbernet Sauvignon, Black Bagal이 백포도주의 경우 Naples의 기호도가 높게 평가되었다. Several domestic new varieties of grapes were utilized for the fermentation of wines, including Cabernet Sauvignon, NY 21576, Canner, SV 18315, Agawan, and Black Bagal red wines, and Naples, Aligote, and Alicante white wines. The °Bx values of the grapes ranged between 17 and 20°Bx. Soluble solid content was adjusted to 21°Bx by adding sugar for all grapes and fermented at 20℃ for 2 weeks. Black Bagal and Cabernet Sauvignon were relatively slower than other grapes with regard to alcohol production rate. The L value of wine made from Agawan and NY 21576 were lower and darker than those of wines prepared from other grapes. Wine made from NY 21576 grapes had a polyphenol concentration of 1.40 ㎎/mL, which was higher than that of any other wine, whereas wines made from MBA and all white wines evidenced value of only 0.55 ㎎/mL and 0.15 ㎎/mL, respectively, after 2 weeks of fermentation. The sensory evaluations demonstrated that the quality of red wines made from NY 21576, Cabernet Sauvignon, Black Bagal, and that of white wines made from Naples grapes were favorable among the different grape variants.

국산 포도주의 품질을 향상시키고 개선하기 위한 발효 방법의 일환으로 국내산 Muscat Baily A 포도 과즙을 약 24 °Brix가 되게 동결농축한 후 포도주 발효를 수행하였다. 효모로는 산업용 포도주 효모인 S. cerevisiae OC2, S. cerevisiae Fermivin, S. cerevisiae W-3를 이용하였으며 이들에 의한 농축 과즙의 알코올 발효를 행하면서 발효 특성과 발효 후 여과하여 제성한 포도주의 품질 특성을 조사하였다. 발효가 끝날 시점의 알코올 함량은 12.6-13.0%로 비슷하였으며 환원당의 함량은 거의 흔적 정도로 검출되었다. pH는 약 3.4-3.7, 총산 함량은 0.62-0.71%로 모든 시험구에서 정상적으로 발효가 일어났음을 알 수 있었다. 발효 종료 후 여과한 포도주의 아세트알데히드, 메탄올, fusel oil의 함량은 식품공전에 명시된 과실주의 기준치보다 매우 낮게 나왔으며 총 폴리페놀 함량은 1.42-1.56 mg/mL 정도를 나타내었다. 각 시험구의 포도주는 모두 농축으로 인하여 진한 색을 띄었고 특히 적색을 나타내는 520 nm에서의 흡광도가 높았으며 이는 색도인 L, a, b 값을 통해서도 확인하였다. 관능검사를 실시한 결과는 색, 향, 전반적인 기호도에서 S. cerevisiae OC2 포도주가 가장 우수한 것으로 나타났으며 향과 맛은 S. cerevisiae Fermivin 포도주가 가장 우수한 것으로 나타났다. Muscat Bailey A grapes, one of the major grape varieties in Korea, contain 18-20% (w/w) sugars, which is less than the amount required to make red wine. In the present study, fermentation of freeze-concentrated Muscat Bailey A grape juice to 24 °Brix was performed using several industrial wine yeasts, including Saccharomyces cerevisiae OC2, S. cerevisiae Fermivin and S. cerevisiae W-3. During fermentation, changes in the levels of soluble solids, alcohols, and yeast viable counts were monitored. Wine quality parameters including organic acid, minor alcohol, sensory score, etc. were also analyzed. Alcohol contents reached maximal levels after 9 days of fermentation, and were 12.6% (v/v) when Fermivin was used and 13% (v/v) when strains OC2 and W-3 were used. No major difference between strains was apparent, except that Fermivin fermentation was somewhat slower in terms of both alcohol production and sugar consumption. Similar levels of soluble solids and total phenols were measured in wines fermented by each of the three strains. The total acid level of W-3 wine was high, whereas the alcohol content of Fermivin wine was low. Although the wines were variable in terms of acetaldehyde and minor alcohol contents, the levels of these materials were much lower than the limits set by the Korean National Tax Service. Upon sensory evaluation, OC2 wine obtained the highest scores in terms of color, flavor, and overall acceptance. However, the best taste score was awarded to the Fermivin wine, which had the same flavor score as OC2 wine but a slightly lower overall acceptance score.

The physicochemical characteristics and antioxidant capacities of 15 red wines (Cabernet Sauvignon) from the US (5) and Chile (10) were investigated. The contents of soluble solid, reducing sugar, titratable acidity, and SO2 were measured. Antioxidant capacities were examined by DPPH, ORAC assay, and total phenolic contents. In addition, polyphenols composition were analyzed by HPLC. The contents of soluble solid, reducing sugar, and acidities were 7.03~8.6 °Brix, 2.7~6.7 g/L, and 0.7~0.8%, respectively, and showed no differences between wines from the two countries (p<0.05). The SO2 content of Chile wines was 50% higher than that of US wines (p<0.05). Antioxidant activities by DPPH assay ranged 5.58~9.80 mM and 6.77~9.48 mM in the US and Chile wines, respectively. The ORAC values of the US and Chile wines ranged 2.17~18.08 mM and 4.55~33.77 mM, respectively. The total phenolic content ranged from 1,315 to 2,651 mg/L among the US red wines, and from 1,653 to 2,493 mg/L among Chile red wines. Gallic acid, catechin, syringic acid, p-coumaric acid, quercetin, and kaempferol were identified by HPLC. The polyphenol contents of the Chile red wines were higher than those of the US red wines(p<0.05). There were no differences in the physicochemical characteristics and the antioxidant capacities of the wines from US and Chile, but only in their SO2 and polyphenol contents (p<0.05).

Effects of the Maceration Enzymes on Evolution of Pyranoanthocyanins and Cinnamic Acids During the Cabernet Gernischet (Vitis vinifera L. cv.) Red Wine Making

Jian-Jun He,Fu-Liang Han,Qing-Quan Yu,Qiu-Hong Pan,Chang-Qing Duan,Guo-Li Cheng 한국식품과학회 2010 Food Science and Biotechnology Vol.19 No.3

The effects of the maceration enzymes on the evolution of 4-vinylphenols pyranoanthocyanins and cinnamic acids were investigated during the Cabernet Gernischet red wine making. The results showed that the contents of p-coumaric acid and caffeic acid in the maceration enzyme-treated wine (the treated wine) were higher than those in the maceration enzyme-untreated wine (the control wine) at the alcoholic fermentation (AF),maceration (M), and malolactic fermention (MLF) stages. Malvidin-3-O-glucoside-4-vinylphenol (Mv-glu-vp) and malvidin-3-O-(6-O-acetyl)-glucoside-4-vinylphenol (Mvacet-glu-vp) were formed at the AF and M stages in the treated wine, while they were formed at the end of MLF stage in the control wine. However, the contents of these 2kinds of 4-vinylphenol pyranoanthocyanins in the control wine were higher than those in the treated wine during aging. These results showed that the use of maceration enzymes in winemaking can promote p-coumaric acid and p-caffeic acid transformed to vinylphenols and accelerate the formation of pyranoanthocyanins.
