  • Numerous studies on the ablactation have been reported since Jundell’s report in 1924. This paper deals with the comparison in nutritional values, composition, economical sense and recommended dietary allowances to Korean infants of the weaning foods sold in Seoul, Jeonju and Gunsan together with the analysis of nutritional compositions of the most recommendable weaning food among those investigated. The results obtained from this study were; 1. Among ten kinds of the weaning foods produced in Korea, only nine sorts could be purchased in Seoul, seven in Jeonju and five in Gunsan. 2. It was difficult to compare directly the compositions of the weaning foods each other because of the differences of the unit indicated. 3. Not only the price of the same product in the same area was differentiated by 10 to 100 won but also the standard of nutritional composition was not identically indicated by the company produced. 4. Since the amount of directed dietary intake was much more than the actual nutritional requirements of Korean infants, waste of money was considered, if used according to the directions. 5. The nutritional compositions of the most recommendable weaning food among those investigated were indicated in Table. 6. More nutritious and economical weaning food adequate to Korean infants must be developed through further scientific, in vivo experiments.

  • Analysis of nutritional compositions of soybean sprouts cultivated with bamboo ash was carried out. Bamboo ash was utilized as sprouting water of soybeans and adjusted to 0.2, 0.6, 1.0, 1.4, 2.0, 6.0 and 10.0 g/L. Stem length and contents of isoflavone (daidzin, glycitin, genestin, daidzein, glycitein, and genestein) and vitamin C in soybean sprouts cultivated with 0.2 g/L were higher than those in soybean sprouts cultivated with only water. Potassium, magnesium, and calcium of all cultivation methods were detected in higher contents than others. In particular, potassium showed a high absorption rate in the soybean sprouts. The major amino acid was asparagine (616.05~849.15 mg/100 g, soybean eq.), and contents of lysine, leucine, and ornithine in soybean sprouts cultivated at 0.2 g/L were higher than those of methods by only water and addition of 6-benzylaminopurine. According to the results, soybean sprouts cultivated with 0.2 g/L of bamboo ash were effective for increasing nutritional compositions.

  • Nutritional assessment of transgenic crops to improve safety evaluations is important for food production. An oxidative stress-tolerant rice was generated by stable insertion of the TC gene-a tocopherol cyclase isolated from tobacco-into the genome of a common variety of japonica colored rice. The nutritional composition of the brown rice grains from the transgenic TC line was compared with that of the parental rice cultivar Heugnambyeo and two different varieties of non-transgenic rice. The results indicate that the analyzed nutritional compositions of the brown grains from the transgenic TC line were within the range of values reported for other commercial lines, and measurements of nutritional compositions were equivalent to those of the non-transgenic rice.

  • In this study, the changes in microbial communities of lamb meat packaged in the air (plastic tray, PT) and in a vacuum pouch (VAC) were assessed by polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) during the storage at $4^{\circ}C$. For the PT lamb, the total viable count (TVC) was $10^7CFU/g$ on Day 5, and the dominated bacteria were Pseudomonas fragi, P. fluorescens, and Acinetobacter spp. For the VAC lamb, the TVC was $10^7CFU/g$ on Day 9, and the dominated bacteria were lactic acid bacteria, including Carnobacterium divergens, C. maltaromaticum, and Lactococcus piscium. One strain of Pseudomonas spp. also appeared in VAC lamb. The relative abundance of Enterobacteriaceae in VAC lamb was higher than that PT lamb, indicating a more important role of Enterobacteriaceae in spoilage for VAC lamb than that of PT lamb. The microbial compositions changed faster in the lamb stored in a PT than that stored in a VAC, and microbial community compositions of the late storage period were largely different from those of the early storage period for both the conditions. The findings of this study may guide improve the lamb hygiene and prolong the shelf life of the lamb.

  • Objective: In this study, we evaluated the nutritional value and antioxidant activity of black goat loin (BGL) and black goat rump (BGR) meat. Methods: We evaluated the proximate compositions, collagen and mineral contents, and fatty acid compositions of BGL and BGR with respect to their nutritional value. The levels of bioactive compounds such as L-carnitine, creatine, creatinine, carnosine, and anserine were also measured. The ferric reducing antioxidant power (FRAP), 2,2-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging, and oxygen radical absorption capacity (ORAC) were assessed to evaluate the antioxidant activity of BGL and BGR. Results: BGR showed higher collagen, Fe, Ca, P, and Na contents than did BGL (p<0.05). Notably, the Ca/P ratio was high in both BGR and BGL (1.82 and 1.54, respectively), thus satisfying the recommendation that the Ca/P ratio is between 1 and 2. BGL showed a significantly higher content of desirable fatty acids (stearic acid and total unsaturated fatty acids) than did BGR. In addition, the levels of creatine, carnosine, and anserine in BGL were higher than those in BGR (p<0.05). There was no significant difference in the antioxidant activity between BGL and BGR, as assessed by FRAP (both $15.92{\mu}mol$ Trolox equivalent [TE]/g of dry matter [DM]), ABTS (12.51 and $12.90{\mu}mol\;TE/g\;DM$, respectively), and ORAC (101.25 and $99.06{\mu}mol\;TE/g\;DM$, respectively) assays. Conclusion: This was a primary study conducted to evaluate the differences in nutritional value and antioxidant activity between loin and rump cuts of black goat meat. Our results provide fundamental knowledge that can help understand the properties of black goat meat.

  • Mulberry (oddi) is one of the most popular functional foods with many physiological components. This study investigated and compared the nutritional compositions and physiological activities of four mulberry fruits from Morus albo L. including Cheongilppong, Iksuppong, Suwonppong and Cheongsuppong (a new cultivar from Chungcheongbuk-do). To analyze the nutrient contents, mulberry fruits were freeze-dried. The results showed that the proximate compositions of the four mulberry cultivars ranged from 9.61~14.11% for moisture, 8.28~11.90% for crude protein, 3.70~4.86% for crude ash, 4.28~5.54% for crude lipid and 7.46~10.78% for crude fiber. The above proximate contents of mulberry cultivars were not significantly different. However, Cheongsuppong had the highest content of reducing sugar, 74.7%. Chungsuppong and Iksuppong showed higher contents of total polyphenol and anthocyanin than other mulberry cultivars, while all mulberry cultivars showed high antioxidant activities. Hypoglycemic effect had a slightly higher level in Suwonppong and Cheongsuppong than in the other samples. Taken together, the new cultivar "Cheongsu" oddi can be suggested as a potential source of functional food.

  • This study investigated the nutritional compositions and physiochemical properties of three domestically cultivated jujube fruits (Boeun, Sangwhang, and Bokjo). Nutrient contents were analyzed by freeze-drying the jujube fruits. The results showed that the proximate compositions of the three jujube cultivars ranged from 7.85~13.52% for moisture, 4.65~5.24% for crude protein, 1.29~2.38% for crude ash, 0.17~1.09% for crude lipid, and 7.66~16.63% for crude fiber. The above proximate contents of jujube cultivars were significantly different. Mineral contents of Al, Fe, Mg, Ca, Na, and K in the three jujube fruits were also determined. Mn, Cu and Zn were not detected in any of the varieties. The content of Al was higher in Sangwhang, while Boeun had higher contents of Ca and K. The total polyphenol, ABTS values, and hypoglycemic effect were slightly higher in Boeun as compared to the other varieties. Taken together, Boeun could be an important source of natural antioxidant as a functional food.

  • To compare the nutritional quality of TPG (Teleaulax / Plagioselmis / Geminigera) clade species of cryptomonads with that of RHO (Rhodomonas / Rhinomonas / Storeatula) clade species 6 Teleaulax amphioxeia (TA) and 1 Rhinomonas sp. strains were mass-cultured in newly designed 500-L photobioreactors to the end of exponential growth phase. Intraspecific variations (IVs) in terms of one standard deviation among the 6 TA strains in the compositions of the three macronutrients were 41.5 (protein), 89.8 (lipid), and 15.6% (carbohydrate) of the mean. When harvested from stationary growth phase mean compositions of essential amino acids (EAAs, 47.3%) and non-EAAs (52.7%) of the 2 TA strains, CR-MAL07 and CR-MAL08-2, were similar to those of a Chroomonas strain. The IVs between the 2 TA strains in the composition of EAAs (10.3 and 2.4) and non-EAAs (8.5 and 2.1% of the mean) were rather smaller than those of saturated fatty acids (30.3 and 26.1) and unsaturated fatty acids (UFAs, 12.0 and 12.5% of the mean) in f/2-Si and urea-based compound fertilizer (UCF) culture media, respectively. Mean compositions of eicosapentaenoic acid (EPA, 17.9%) and docosahexaenoic acid (DHA, 12.7%) of total fatty acids of the 2 TA strains were higher than those that of a Chroomonas strain. EPA and DHA compositions exhibited similar level of IVs between the 2 TA strains in f/2-Si (14.6 and 11.0) and UCF media (12.6 and 13.5% of the mean). Thus, the nutritional quality in terms of amino acids, UFAs, EPA, and DHA in a TPG clade species, T. amphioxeia was comparable to those of RHO clade species with notable IVs. Practically, biotechnological targets for TPG clade cryptomonad strains might be subspecies or clone level.

  • Though the edible bovine by-products are widely used for human consumption in most countries worldwide but the scientific information regarding the nutritional quality of these by-products is scarce. In the present study, the basic information regarding the yields, physicochemical and nutritional compositions of edible Hanwoo bovine by-products was studied. Our results showed that the yields, physicochemical and nutritional composition widely varied between the by-products examined. The highest pH values were found in rumen, reticulum, omasum and reproductive organ. Heart, liver, kidney and spleen had the lowest CIE $L^*$ values and highest CIE $a^*$ values. Liver had the highest vitamin A, B2 and niacin contents whereas the highest B1 and B5 contents were found in kidney. The highest Ca content was found in rumen, reticulum, omasum, head and leg while the highest Mn and Fe contents were found in rumen, omasum and spleen, respectively. Liver had the highest Cu content. Total essential amino acids (EAA)/amino acids (AA) ratios ranged between the by-products from 38.37% to 47.41%. Total polyunsaturated fatty acids (PUFA) levels ranged between the by-products from 2.26% to 26.47%, and most by-products showed favorable PUFA/SFA ratios. It is concluded that most of by-products examined are good sources of essential nutrients and these data will be of great importance for promotion of consumption and utilization of beef by-products in future.

  • In this study, Artemisia capillaris, which has been used in oriental medicine and folks remedy, was investigated to characterize the nutritional composition (protein, lipid, ash, fiber, amino acids, fatty acids, Na, K, P, Mg, Ca and Fe) and effective substance (scopoletin). Artemisia capillaris has often been cited in medical literature for its medicinal effects. The Korean Food and Drug Administration allowed Artemisia capillaris as a food stuff and indicated as In-Jin-Sook. From the view point of the subjects who eat In-Jin-Sook products, most of them ingested it for a certain pharmacological efficacy rather than as a beverage or a food. Therefore, we need to develop functional foods using In-Jin-Sook. Artemisia capillaris was superior in protein, crude fiber, amino acid and fatty acid compositions to wild greens according to Korean Nutritional Composition Table. Also scopoletin, blown for blood vessel relaxation and hypotensive effect, was detected at the level of 326.13 $\mu\textrm{g}$/g. These results demonstrated that Artemisia capillaris has both pharmaceutical effects and balanced nutritional contents. Artemisia capillaris has sufficient values to use as a food stuff for functional foods.
