  • Today, producers of ginseng spray prohibited fertilizers or use excessive amount of fertilizers whereas distributers either claim that they are selling domestic ginseng when in fact they are selling imported ginseng, cheat on the age or weight of ginseng, or mix domestic and imported ginseng. In terms of quality in comparison with foreign ginseng, 90% of the people surveyed responded that domestic ginseng is more efficacious. When asked whether they would purchase foreign ginseng products when they become available in the market, only one of the respondents responded that he or she would purchase foreign ginseng whereas 50 respondents or 81% of the total surveyed responded that they wouldn't purchase foreign ginseng. About half of the respondents answered that when Chinese red ginseng, ginseng, or wild ginseng products cultivated with harmful fertilizers become available in the market, they would either reconsider purchasing ginseng products or stop purchasing ginseng products all together. In order to develop the ginseng industry 20 respondents (25%) chose the establishment of the standards, 33 respondents (42%) chose marking the place of origin, 15 respondents (19%) quality improvement, 7 respondents (9%) research on the efficacy, and 4 respondents (5%) said improvement on the storage methods as the important factors of the ginseng industry. Considering the fact that 77% of the respondents selected either the standardization or marking of the place of origin, the consumers seem to be demanding reliability in the distribution of ginseng products. Therefore, those people who work in the industry such as the producers, distributors and others should have a sense of mission to develop ginseng, which is a gift from God, and do their best to produce and distribute ginseng products.

생강 및 인삼 분말 첨가가 돈육포의 휘발성 염기태 질소, 미생물 수 및 관능평가에 미치는 영향 (Effects of Storage and Supplementation with Ginger and Ginseng Powder on Volatile Basic Nitrogen, Aerobic Plate and Sensory Evaluation of Pork Jerky)

  • 본 연구는 돈육 중의 후지육을 이용하여 천연 향신료인 생강 및 인삼 분말을 첨가비율별로 처리(무처리 대조구, T1구(A-생강 분말 0.1% 첨가, B-인삼 분말 0.1% 첨가), T2구(A-생강 분말 0.2% 첨가, B-인삼 분말 0.2% 첨가), T3구(A-생강 분말 0.3% 첨가, B-인삼 분말 0.3% 첨가)하여 돈육포를 제조한 후, 저장기간에 따른 VBN, 미생물 수 및 관능평가에 미치는 영향을 조사하였다. 돈육포의 VBN 함량은 대조구와 처리구간에서는 통계적인 유의차가 나타내었고(p<0.01), 저장기간이 길어짐에 따라 VBN 함량과 총 세균수 및 대장균 수도 점차 증가하는 경향을 나타내었다. 또한 처리구에 상관없이 생강 분말 첨가군(A)이 인삼 분말 첨가군(B)군보다 유의적으로 낮게 나타났다(p<0.01). 돈육포의 관능평가의 경우, 육색과 맛은 처리구에 상관없이 저장기간이 길어짐에 따라 저장 2주째에 가장 높아 통계적인 유의차가 나타났고(p<0.05), 그 이후는 서서히 낮아졌다. 특히 육색의 경우, T1구의 A군이 다른 처리구보다 크게 높게 나타났다(p<0.05). 이상의 결과로 볼 때 돈육포 제조 시 생강 분말 첨가는 미생물의 증식 억제에 다소 영향을 미치며, 육포 제조 후 2주째에 가장 맛이 좋은 것으로 판단된다.

  • 인삼은 다년생 식물로 종자 번식을 하는데, 수확 시 미성숙한 배(embryo)를 가지고 있어 후숙이 필요하다. 기후변화에 대비하고 안정적인 종자 보급을 위해서는 단기 및 장기간 대량으로 종자를 저장할 수 있는 기술이 필요하다. 본 연구에서는 2개 지역에서 얻은 개갑된 인삼 종자를 수분함량을 달리하여 -3.5℃에 보관하고, 저장 3, 15, 27개월 후에 유근과 지상부 출현을 관찰하여 발아력 검정을 통해 종자 저장성을 조사하였다. 3개월 후, 전반적으로 batch #1보다 batch #2에서 발아율이 높았고, 그리고 수분함량이 35% 이상에서만 발아가 원활하였다. 15개월 후, batch #2에서 수분함량이 45~54%인 부분 건조된 종자들에서 가장 높은 발아율을 보였고, 대부분의 무건조 종자는 부패하며 발아에 실패하였다. 수분함량 25% 이하로 건조된 종자들 역시 유근발아 또는 출아가 불량하였다. 부분 건조 종자들은 토양에서의 발아 및 생육도 우수하였지만, 1년 뒤에는 역시 활력을 유지하지 못하였다. 요약하면, 인삼 종자는 온대성 난저장 종자의 특성을 가지는 것으로 보이며, 부분 건조 조건에서는 종자의 수명을 연장할 수 있어 1년 정도의 단기 저장에 활용할 수 있을 것으로 판단된다.

  • Electron beam, electrically produced from an electron accelerator, was compared with gamma energy in terms of its influence on color and organoleptic qualities of ginseng powders when exposed to the energy used for their microbial decontamination. Hunter color L and b values were suitable for measuring color characteristics of ginseng powders, which were not significantly changed by the exposure to 5 to 7.5 kGy electron beam and gamma energy. Fifty percent ethanol extracts of irradiated ginseng powders at 10 key showed negligible differences from the non-irradiated control in the pattern of absorption spectra at 280∼800 am, but showed increased values in overall color difference (AE) as compared with powdered samples. Irradiation more than 10 kGy and storage at ambient temperature for 4 months caused browning of powdered samples. Irradiation at more than 10 kGy of electron beam was found a critical level to bring about appreciable changes (p<0.05) in or-ganoleptic qualities such as color and odor of sterilized samples, and red ginseng powder was more susceptible than white one to organoleptic changes by irradiation.

  • Stability of nitrogen compounds in the water-extract of ginseng has been investigated in terms of concentration and SDS-PAGE protein pattern as functions of times and temperature. The concentration of free amino-nitrogen in the extract of fresh ginseng varied with time at various temperatures. Especially at temperature over 90$^{\circ}C$, it showed a tendency of steady declease at a considerably fast rate. In the case of red ginseng which had been commercially processed and stocked for 1-7 years, it was found that the free amino-N concentration diminished gradually depending on the length of stock period of samples. This result may be comparative to another observation that the amount and density distribution of precipitate from extract varied with the lapse of stock time, based on accelerated sedimentation test. The number of SDS-PAGE protein bands was observed to be at least seven when determined with the extract of fresh ginseng. However, it tended to reduce finally to be one band when the extract was kept at a rather high temperature for a long time.

  • Ginseng root starch, prepared by conventional method, contained crude lipid of 0.5%, crude protein of 0.4%, crude mineral of 0.17% and phosphorous of 12.5mg% as noncarbohydrate constituents. The amylose content of ginseng root starch picked in Summer (May to August) and Winter (November to March) was 32-35% and 15-20%, respectively, and it was decreased with a growing preiod of ginseng. The blue value, alkali number and ferricyanide number of the starch were 0.14-0.17, 8.50 and 0.781, respectively. The molecular weight of amylose in the starch was estimated to be 1.27-7.95${\times}$105 by means of periodate oxidation, and the degree of branching and glucose unit per segment of amylopectin were 3.50-3.53% and 28.3-28.5, respectively, The starch content of ginseng root was decreased when dried under sunlight and stored at 5$^{\circ}C$ for twenty days. In contrast, sucrose content in the root was increased from 3.8% in fresh state to 11.5% during storage at the above condition. In the other hand, starch was converted to maltose by heating at temperature above 70$^{\circ}C$.

  • Sprout ginseng paste were prepared with pine nut, dry oyster and dry shrimp to examine the antioxidant properties(total polyphenols, total flavonoids, and electron donating ability) and sensory test(attribute difference and acceptance). Sprout ginseng paste were measured based on color value, pH, viscosity, total bacteria cell numbers for 0 and 20 days at $4^{\circ}C$. The higher total polyphenol and total flavonoid content of sprout ginseng paste added with pine nuts, dry oyster, and dry shrimp were higher antioxidant capacity. DPPH radical scavenging activity was increased from 52.2% (SGP0) to 79.5.0 % with SGP5. The attribute test results reveal that the color intensity, bitter taste, and oily taste were decreased in SGP3 to SGP6. Taste, flavor, and coarseness did not show significant difference in SGP0 to SGP6. Thickness and After taste were increased in SGP4 to SGP6. The preference test results reveal that the appearance, flavor, and texture level did not show significant difference in SGP0 to SGP6. Taste and overall preference were increased in SGP4 to SGP6. L value, pH, decrease while a value and b value show no change in sprout ginseng paste with pine nut, dry oyster and dry shrimp. Total cell number was not detected during storage.

  • This study evaluates the microbial safety of ginseng sprouts packaged in moss and a modified atmosphere (MA) film within Styrofoam boxes. Ginseng sprout samples were stored at 4℃ for seven days, and the total fungi and aerobic bacteria counts, relative humidity, and moisture content were measured at 0, 1, 3, 5, and 7 days. During the storage period, both packaging treatments caused an increase in the total fungi and aerobic bacteria counts. However, by the seventh day, the ginseng sprouts packaged in the MA film demonstrated significantly lower counts of total fungi (3.03 log CFU/g) and aerobic bacteria (7.32 log CFU/g) than those in moss (3.66 and 7.63 log CFU/g, respectively). Moss packaging alone resulted in the total fungi count reaching up to 3.36 log CFU/g, with the aerobic bacteria count consistently exceeding 7 log CFU/g, highlighting the importance of hygienic management. Moreover, no significant differences were observed in the moisture content and relative humidity between the MA-film- and moss-packaged groups throughout storage. These findings indicate that the functional MA film is a more hygienic packaging solution for ginseng sprouts than moss.
