  • Microalgae are unicellular microorganisms inhabiting various ecosystems of the world, including marine and freshwater systems and extreme environments. Only a few species have been actively used as food. Microalgae are attracting attention as a means of biological CO2 reduction because they play an important role in absorbing atmospheric CO2 through their rapid growth by photosynthesis in water. Besides, microalgae are considered to be an eco-friendly energy source because they can rapidly produce biomass containing a large quantum of lipids that can be converted into biodiesel. Several microalgae, such as Chlorella spp., Spirulina spp. and Haematococcus spp. have already been commercialized as functional health supplements because they contain diverse nutrients including proteins, vitamins, minerals, and functional substances such as docosahexaenoic acid (DHA), β-glucan, phycocyanin, astaxanthin, etc. Moreover, they have the potential to be used as food materials that can address the protein-energy malnutrition (PEM) which may occur in the future due to population growth. They can be added to various foods in the form of powder or liquid extract for enhancing the quality characteristics of the foods. In this review, we analyzed several microalgae which can be used as food additives and summarized their characteristics and functions that suggest the possibility of a role for microalgae as future food.

  • In this study, the effects of feeding citrus by-products on the quality and fatty acid compositions of chicken eggs were investigated. Two samples of chicken eggs were used for this study: T0 (eggs of chickens that were not fed citrus byproducts) and T1 (eggs of chickens that were fed 4% citrus byproducts). There was no statistically meaningful difference between T0 and T1 in terms of various properties, such as chemical composition, cholesterol content, minerals, vitamins, pigments, and total structural amino acid. The caloric content of the egg yolk was higher in T1 than in T0, and total free amino acid of egg albumin and egg yolk was higher in T1 than in T0 (p<0.05). There was a not significant difference in SFA:UFA ratio between T0 and T1, but the linolenic acid content was higher in T1 than in T0 (p<0.05). The results of this study show that citrus by-products can be used for feed for laying hens by adding them to general feed.

  • This study investigated the effects of astaxanthin, which is used to improve the muscle color of fish, on the nutritional composition of rainbow trout (Oncorhynchus mykiss). The trout were fed extruded pellets containing astaxanthin (pigmented rainbow trout) or without astaxanthin (non-pigmented rainbow trout). No significant differences in the contents of crude protein and crude ash between the two muscles of the two groups were observed. However, the crude fat composition of the muscle of pigmented rainbow trout was about two times higher than that of control muscle. In the muscle of pigmented rainbow trout, the contents of docosahexaenoic acid (DHA, 22:6n-3) and eicosapentaenoic acid (EPA, 20:5n-3), which are functional polyunsaturated fatty acids, were 1.6 fold higher than in non-pigmented muscle. In addition, the contents of minerals such as Zn and Fe, vitamins (B group, C, and E), free amino acids, carotenoids and astaxanthin were increased in the muscle of rainbow trout fed pellets supplemented with astaxanthin. Specifically, the content of the bioactive compound astaxanthin, was increased six times in the pigmented muscle, as compared to the control muscle. The results suggest that a diet supplemented with astaxanthin improves the nutritional composition of rainbow trout muscle as well as improving the muscle color.

  • The purpose of the present study is to develop a simple, fast and sensitive LC/MS method for simultaneous separation and the determination of an active component in the oriental medicinal mushroom Cordyceps militaris. Based on this work, the contents of cordycepin in Cordyceps militaris fruiting cultivated on various media were determined and compared. And also, the nutritional components such as minerals and vitamins were determined in order to provide useful information to consumer as a food material. The analysis methods of nutritional components were chosen on the basis of AOAC. The optimum separation for cordycepin was achieved using a solvent gradient consisting of the mixture of 0.1% formic acid in methanol (solvent B) in a background of 0.1% formic acid in water (solvent A) as a mobile phase and a 3.0${\times}$150 Waters XTera column. Selective ion monitoring (SIR) mode ([M+H]+ at m/z 252) was used for quantitative analysis of cordycepin. The cultivated Cordyceps militaris on various media contained 1~14 /g of cordycepin, 0.65~1.08% of thiamine, 0.86~7.17% of riboflavin, and 3.01~5.26% of niacin. The content of mineral components varied on categories, especially contained 500~3500% of potassium as a major mineral. Cordycepin, niacin and potassium were found much higher in the fruiting cultivated with soy power media (gold 10) than other media.

  • Solanum lycopersicum, commonly known as tomato, is widely used in raw, cooked, or liquid forms because it contains nutritional compounds that are beneficial for human health, including carotenoids, lycopene, ascorbic acid, vitamins, and minerals. The tomato is perhaps the most widely studied fruit, especially with respect to its cardioprotective effects. In this study, we aimed to identify the anti-inflammatory mechanisms by which the tomato elicits its anti-inflammatory properties. We treated murine macrophage RAW 264.7 cells with a tomato ethanol extract and performed various biochemical assays including nitric oxide inhibition, cell viability, RNA extraction, expression of pro-inflammatory mediators and cytokines, and immunoblotting, as well we assessed cell survival rates. Our results have shown for the first time that a tomato ethanol extract treatment can suppress nitric oxide production in a dose-dependent manner without cytotoxicity. Moreover, it inhibits the expression of pro-inflammatory mediators and cytokines and elicits its anti-inflammatory effects via the nuclear factor kappa-light-chain-enhancer of activated B cells ($NF-{\kappa}B$) and mitogen-activated protein kinase (MAPK) pathways. In addition, administration of tomato syrup potently rescued mice from septic shock induced by lipopolysaccharide injection. Collectively, our results elucidate details regarding the anti-inflammatory mechanisms of tomato.

  • Potatoes were first introduced outside the Andes region four centuries ago, and have become an integral part of much of the world's food. Potatoes were first introduced into Europe in the 16th century and Korea in the early 19th century. It is the world's fourth-largest crop, following rice, wheat, and maize. In the nutritional aspects, potatoes contain abundant vitamins and minerals, as well as an assortment of phytochemicals such as carotenoids and natural phenols. Chlorogenic acid constitutes up to 90% of potato natural phenols. Due to the high content of potato functional compounds, it has known that potatoes are effective in the prevention of various human diseases. Recently, potato 'Seohong' was developed by RDA, and it has reported that they have a high-yield and dry matter content. Processing industry of potato generates high amounts of peel as a byproduct. It was reported as a good source of several beneficial functional ingredients including antioxidant effect. This study was conducted to enhance the utilization of the peel of Potato 'Seohong'. The anti-inflammatory effects on solvent fraction was evaluated. The anti-inflammatory activities of Ethylacetate fraction was evaluated for inhibitory activities against lipopolysacchride (LPS) induced nitric oxide (NO) in RAW264.7 cell lines. The fraction inhibitory activity for tests with $IC_{50}$ values showed in the ranges of $50{\mu}g/ml$. This result revealed that n-butanol fraction of 'Seohong's peel is expected to be good candidate for development into source of anti-inflammatory agent.
