  • The effect of fermented spinach extracts on color development in cured meats was investigated in this study. The pH values of raw cured meats without addition of fermented spinach extract or nitrite (negative control) were higher (p<0.05) than those added with fermented spinach extract. The pH values of raw and cooked cured meats in treatment groups were decreased with increasing addition levels of fermented spinach extract. The lightness and yellowness values of raw cured meats formulated with fermented spinach extract were higher (p<0.05) than those of the control groups (both positive and negative controls). The redness values of cooked cured meats were increased with increasing fermented spinach extract levels, whereas the yellowness values of cooked cured meats were decreased with increasing levels of fermented spinach extract. The lowest volatile basic nitrogen (VBN) and thiobarbituric acid reactive substances (TBARS) values were observed in the positive control group with addition of nitrite. TBARS values of cured meats added with fermented spinach extract were decreased with increasing levels of fermented spinach extract and VBN values of curing meat with 30% fermented spinach extract was lower than the other treatments. Total viable bacterial counts in cured meats added with fermented spinach extract ranged from 0.34-1.01 Log CFU/g. E. coli and coliform bacteria were not observed in any of the cured meats treated with fermented spinach extracts or nitrite. Residual nitrite contents in treatment groups were increased with increasing levels of fermented spinach extract added. These results demonstrated that fermented spinach could be added to meat products to improve own curing characteristics.

  • In this study kinds of Lamb cooking and preservation and the ingredients of lamb cooking are surveyed through the references written from 1670 to 1943. The lamb cooking found in the literature totaled to more than 53. They can be classified into fourteen different groups according to their processing features which as follows: Salnum and Pyunyuk(boiled and slices of boiled), Kui(roasted), Chim(steamed), Whe(raw meat), Hounjae(smoking), Po(dried), Juk(gruel), Tang(soup), Sundae(stuffed small interstines), Jokpyun(jellied foot), Jungol(happiness pot), Sikhae(salt+meat+malt), Oumjang(salted meat), Kunjo(dried). Korean lamb cooking methods were primarily adopted from Mogolia in late Korea Dynasty but they had unique characteristics different from Mongolian ones. Furthermore, they were creatively applied to other meat cooking such as beef, pork and dog. About twenty one ingredients were mainly used in lamb cooking, including fresh meat, ribs, breast, heart, liver and the like. In particular, most popularly used ones were fresh meat and the heart in internal organs, which coincide with the main ingredients in beef cooking of today. The number of seasoning used in lamb cooking was twelve and especially salt, vineger, ginger and stone leek were most commonly used ones. Fourteen other addition were put into lamb cooking and the rice(Korean) wine was the most frequently used addition.

  • The aim of this study is to compare the anti-inflammatory and immunological activity of different parts (bone, meat, and rind) of Yeonsan Ogye (YO). In order to evaluate cytotoxicity, MTT assay was performed. We investigated the production of nitric oxide (NO) and pro-inflammatory cytokines, such as IL-$1{\beta}$, IL-6, and TNF-${\alpha}$, in LPS-induced RAW264.7 cells. All parts of the YO showed no toxicity at concentrations of 1, 10, and $100{\mu}g/m{\ell}$. Rooster's bone, hen's bone, and rind decreased the production of NO. And rooster's bone, meat, and hen's bone also attenuated TNF-${\alpha}$ production in LPS-induced RAW 264.7 cells. In addition, all parts of the YO decreased IL-$1{\beta}$ and IL-6 production in LPS-induced RAW264.7 cells, whereas they all increased IL-$1{\beta}$, IL-6 and TNF-${\alpha}$ production in normal RAW264.7 cells. Rooster exhibited higher immune activation and inhibitory activity on inflammation than a hen, and among different parts of the YO, bone showed the highest activity. Our results demonstrated and compared the anti-inflammatory and immunological activity of different parts of the YO. These results suggest that YO may be developed as a raw material for new health supplement food and medicine to attenuate various symptoms related to inflammation and immunity.

  • The effects of additions of lotus leaf (0.1 and 0.5%) and barley leaf powder (0.1 and 0.5%) on the lipid oxidation and microbiological analysis of raw minced pork were investigated after 1, 4, 7, and 10 d at chilled storage. Days of storage caused (p<0.05) decreases in pH values in samples with lotus leaf (LP) and barley leaf powder (BP). $L^*$ and $a^*$ values decreased, and $b^*$ values increased in the treatments with increasing lotus leaf and barley leaf powder contents, respectively. The decrease in $a^*$ values was lowest (p<0.05) in the treatment with 0.1% BP. Thiobarbituric acid reaction substance values and free fatty acids in 0.5% LP were lowest (p<0.05) on day 10. Thus, the addition of lotus leaf powder significantly improved lipid oxidative stability in the raw minced pork during chilled storage of 10 d. Furthermore, the raw minced pork treatments with LP and BP presented low peroxide values and total microbes as compared to control (-) (without LP and BP). These results indicate that LP and BP can be incorporated into raw minced pork as natural additives to retard oxidation.

  • 1967년 7월부터 12월까지 상어육의 연제품 으로서의 원료학적 고찰 및 제품가공실험 결과를 요약하면 다음과 같다. 1) 상어육은 연제품 원료로서 타 어종에 비해 비교적 많은 양의 염용성 단백질을 함유하므로 연제품 원료로서 상당히 우수한 어종이다. 2) 설취에 있어서는 빙초산 농도를 $0.05\%$ 이상하지 않는 것이 제품의 탄력을 높힐 수 있다. 3) 가능한한 원료취급을 가열전까지 저온에서 행하는 것이 탄력저하를 방지 할 수 있다. 4) Setting(Sowari)의 적당한 온도 시간은 $35\~40^{\circ}C$에서 $40\~70$분으로 하는 것이 가공시간 단축과 제품탄력을 높힐 수 있다. 5) 가열시간과 온도는 $80\~90^{\circ}C$에서 $40\~60$분 정도가 가장 양호하며 보장기간을 장기간 할려면 그 이상의 시간 온도를 요하나 제품탄력을 고려치 않으면 안된다. 6) 맛의 보강을 위해 부원료 사용시 부원료량이 다량일수록 제품은 우수하나 생산원가를 고려하여 장어 $20\%$ 강달이 $30\%$ 이내로 사용하는 것이 적당하다. 7) 보장 있어서 $0.2\%$ 솔빈산 가리를 첨가한 것은 상온에서 20일 $5^{\circ}C$에서 50일간 저장가능하며 직공포장을 한다면 더 장기간 보장할 수 있으리라 사료된다.

  • The aims of this study were to examine contamination sources and provide the basic data in establishment of sanitary standard for raw pork meat. From \"Random sampling(I)\", initial total plate counts of post-slaughter samples for the group A, B and C were 1.5${\times}10^4$cfu/$textrm{cm}^2$, 5.5${\times}10^5$cfu/$textrm{cm}^2$ and 1.8${\times}10^4$cfu/$textrm{cm}^2$, respectively, and of post-prechilling samples for the group A, B and C were 1.0${\times}10^4$cfu/$textrm{cm}^2$, 4.6${\times}10^5$cfu/$textrm{cm}^2$ and 2.5${\times}10^4$cfu/$textrm{cm}^2$, respectively. Initial total plate counts of post-transportation samples for the group D, E and F did not increased, as did the group A, B and C. From \"Normal sampling(II)\", initial total plate counts of post-slaughter, post-prechilling, post-transportation and post-2 days preservation samples were 7.3${\times}10^4$cfu/$textrm{cm}^2$, 9.6${\times}10^4$cfu/$textrm{cm}^2$, 2.0${\times}10^5$cfu/$textrm{cm}^2$ and 2.5${\times}10^5$cfu/$textrm{cm}^2$, respectively. From \"Clean sampling(III)\", initial total plate counts of post-slaughter, post-prechilling, post-transportation and post-2 days preservation samples were decreased to 7.0${\times}10^2$cfu/$textrm{cm}^2$, 7.5${\times}10^2$cfu/$textrm{cm}^2$, 8.5${\times}10^2$cfu/$textrm{cm}^2$ and 5.5${\times}10^3$cfu/$textrm{cm}^2$, respectively, compared with "Normal sampling(II)". No E. coli O157:H7, Staphylococcus aureus and Salmonella were detected at each sampling step. Consequently, a slaughter method like "Clean sampling(III)" showed a better sanitary effect to low total plate counts of 10$^2$∼10$^3$times, compared with "Normal sampling(II)". The one of contamination sources for raw pork meat was at a slaughtering step, and "Clean sampling" method may be considered as the one of sanitary standards.

  • 발효에 의한 향미특성과 저장성이 양호한 새로운 저염 오징어젓갈의 제조기술을 개발하고자 원료어육의 수분활성도와 염농도, papain과 glucose의 첨가농도 등 적정 제조조건에 대하여 조사하였다. 오징어육의 수분활성도를 0.94, 0.90과 0.88로 조절하고 3, 5와 7%의 식염을 첨가하여 제조한 오징어젓갈을 $10^{\circ}C$에서 6주간 숙성하였을 때 아미노태질소는 수분활성도가 높고 염도가 낮을수록 함량이 높았으며 수분활성도 0.90이고 식염농도가 5%인 경우 관능적 품질이 양호하였고 30일 이상 유통가능하였다. 수분활성도를 0.90으로 조절하고 5% 식염으로 염장한 오징어육을 papain의 첨가농도를 달리하여 $10^{\circ}C$에서 숙성하였을 때 papain의 첨가농도가 높을수록 단백질의 분해가 빨랐으며 관능적 품질은 papain 0.1%를 첨가한 처리구가 가장 양호하였다. 또한 수분활성도를 조절하여 5% 식염으로 염장한 오징어육은 1% glucose의 첨가로 유기산 발효를 촉진시켜 5주경에 pH 5.8로 저하하므로서 대조구의 최저 pH 6.13에 비하여 비교적 낮았으므로 저장성 연장효과가 기대되었다.

  • The purpose of this study was to investigate the recent development of meat analog, industrialization, and the related legal changes worldwide. Summarizing the current status of the industrialization of meat analog, studies on plant-based meat, mycoprotein, and edible insects were mainly conducted to investigate their sensory properties (texture, taste, flavor, and color resembling meat), nutritional and safety evaluations, acquisition method of meat alternatives, and commercialization. Cultured meat is mainly studied for developing muscle satellite cell acquisition and support techniques or materials for the formation of structures. However, these technologies have not reached the level for active industrialization. Even though there are differences in the food categories and labeling between countries, it is common to cause confusion or to relay false information to consumers; therefore, it is important to provide accurate information. In this study, there were some differences in the food classification and food definition (labeling) contents for each country and state depending on the product shape or form, raw materials, and ingredients. Therefore, this study can provide information about the current research available on meat alternatives, improve regulation, and clarify laws related to the meat analog industry, which can potentially grow alongside the livestock industry.
