  • Chicken meat is a low-fat and high-protein food and consumption of chicken meat has been increasing globally. Various food ingredients are widely added for their specific purpose to processed chicken meat. Nonetheless, concerns about the association between high sodium intake and various diseases as well as negative perceptions of artificial additives are increasing. Therefore, in meat products, it is necessary to reduce the amount of salt and to replace artificial additives with natural ingredients. Our aim was to investigate the quality characteristics of low-salt chicken sausages manufactured with the addition of a winter mushroom powder. Sausages was manufactured with sodium pyrophosphate (0.3%) or winter mushroom powder (0%, 0.5% and 1.0%) to ground chicken breast. As a result of addition of the winter mushroom powder to low-salt chicken sausages, pH of the meat batter increased, and the proportion of jelly and melted fat exuded from sausages was reduced. The texture of sausages was softened and lipid oxidation in sausages was inhibited by the winter mushroom powder. This powder did not negatively affect the color and sensory properties of the sausages. According to the results of this study, the winter mushroom powder can serve as a natural ingredient to improve quality of low-salt chicken sausages.

  • ${\gamma}$-Aminobutyric acid (GABA) is basically neurotrasmitter produced by the decarboxylation of L-glutamic acid catalyzed by glutamic acid decarboxylase (GAD), which was known to convert monosodium glutamate (MSG) to GABA. To investigate enhancement of reversion rate of GABA, the yogurt fermentation with addition of nanoparticle winter mushroom and hydroponic ginseng was used. The conversion rate was revealed to nanoparticle winter mushroom and hydroponic ginseng fermenter (88%) > winter mushroom fermenter (52%) > nanoparticle winter mushroom fermenter (44%). The results showed that nanoparticle winter mushroom and hydroponic ginseng supplemented substrates for enhancement of GABA may be used more effectively as one of potential sources of functional foods.

  • Various studies on the effect of mushroom, a member of phytonutrients, on inflammatory diseases have been reporter over the years, Among various species mushrooms, King oyster mushroom (Pleurotus eryngii) and winter mushroom (Flammulina velutipes) are popular dietary ingredients for Asian cuisine. The extracts from all the three mushrooms were used to determine the antioxidative effect and the cytotoxicity. Result analysis were repeated more than three times to get an average${\pm}$standard deviation, and statistical significance were confirmed by SPSS. As a result, total phenol content of the king oyster mushroom and the winter mushroom were $19.66{\pm}0.10mg/g$ and $22.08{\pm}1.10mg/g$, respectively. Also, the total flavonoid content was $15.21{\pm}1.31mg/g$ for the king oyster mushroom and $20.50{\pm}4.52mg/g$ for winter mushroom. The results in winter mushroom showed higher values in total phenol and flavonoid content than in the king oyster mushroom. All samples of extracts showed free radical DPPH (1,1-diphenyl-2-picrylhydrazyl) scavenging activity with their 10 mg/mL concentration. These results indicate that the extract of the king oyster mushroom (Pleurotus eryngii) and the winter mushroom (Flammulina velutipes) may be possible phytonutrients with the anti-inflammatory and the anti-cancer effect.

  • Quality change of winter mushroom were investigated during storage and distribution phase as influenced by storage temperature. According to storage period and temperature, amino acids, were analysed and quantified with the mushroom fruiting bodies using HPLC and morphological characteristics were investigated. Characteristic changes of winter mushroom fruiting bodies were described as follows during storage according to the storage temperature. Looking at the results of the analyzed amino acid contents, temperature between $-1^{\circ}C$ and $4^{\circ}C$ was optimal condition for the storage. At $4^{\circ}C$, the chemical composition tended to be maintained. On the other hand, the results indicate the rapid loss of nutrition at $-1^{\circ}C$ within 7 days of storage. Exceptionally, proline was shown to be increased. Brown line mushroom had a larger loss than white line mushroom. Based on this result, brown line mushroom have shown significant differences among varieties. Therefore, winter mushroom should be stored at $4^{\circ}C$ to minimize nutrient loss and to maintain freshness and mushrooms should be consumed within 14 days after harvest.

  • Mushroom cultivation in Korea was launched in the early 1960's. At that time Korean government started a program for increasing cultivation of button mushroom (Agaricus bisporus) and oak mushroom (Lentinula edodes) to export agricultural products and to increase farm income. National research institutes under Rural Development Administration, Korea Forest Service, etc. play a leading role in mushroom industry as follows : Development and spread of genetically superior commercial strains, good spawns, and cultivation techniques. Training and field advice to lead farmers for mass production of high quality mushrooms. Political support of facilities and establishments for mushroom cultivation. Several mushrooms including oak mushroom, button mushroom, oyster mushroom, winter mushroom, Ganoderma, P. eryngii, etc. have been popularized for their cultivation techniques and produced in large quantities in the farm. According to a recent statistics, mushrooms have been grown by about 20,000 farm households, in Korea and the gross production of fresh mushrooms is estimated about 170,000 M/T. The gross production of oyster mushroom is the highest followed by winter mushroom, oak mushroom and button mushroom. The gross amount of mushroom production stands over 700 billion won. Thus, mushroom industry goes to the most important cash crop to be produced yearly.

  • To provide a basis for the variation of fruit bodies of winter mushroom (Flammulina velutipes), the organic acid composition of its fruit bodies was investigated with several varieties of winter mushroom indifferent temperature and storage period. In the fruit bodies of winter mushroom, a total of 10 organic acids including acetic acid, butyric acid, citric acid, fumaric acid, DL-isocitric acid, L(+)lactic acid, D-malic acid, propionic acid, succinic acid, and D-tartaric acid were detected. In the most of the winter mushroom, acetic acid was the main organic acid component and fumaric acid was the least included component. Acetic acid, which is a mono-carboxyl group of organic acid, is contained in different levels according to different varieties and different storage temperature. Butyric acid is extremely variable in its quantity, depending on variety and different storage temperature. In contrast, fumaric acid, which is a dicarboxyl group of organic acid, decreased in its quantity during storage with 1.5 mg/g. Especially, ASI 4149, 4166 varieties tend to differ in their quantity. Besides, malic acid is extremely variable in its quantity according to variety and storage temperature. Citric acid, a tri-carboxyl group of organic acid, increased in its quantity according to storage period, which enables us to efficiently manage storage period. Isocitric acid is also extremely variable in its quantity according to variety, storage temperature and storage period.

  • Winter mushroom was monitored to investigate the influence of storage temperature on its quality during the storage and distribution phase. In measuring its quality, the contents of saccharides were quantified with its fruiting bodies using HPLC. Although it has been known to be difficult to separate saccharide isomers, our results indicated that Grace Prevail carbohydrate ES $5{\mu}column$ was the best in the separation to analyze the saccharide out of six columns used in this study. In our results, xylose was the main component of saccharide in the fruiting body of winter mushroom(White line mushroom:47.68mg/g, brown line mushroom: 63.28mg/g). In long-term storage, the total amount of saccharide tended to increase, but trehalose content of the disaccharide decreased. In comparison with the paramount amount of lactose and myo-inositol contents in long-term storage at $4^{\circ}C$, lactose wasn't detected when stored at $-1^{\circ}C$.

  • Total eight different winter mushroom (Flammulina velutipes) strains were characterized by comparisons of fruiting body morphology, hardness and color after growing at different temperature. Although variations depending on the strains were observed, in general, both stipe length and pilus diameter were shorter while pilus thickness was bigger as growing temperatures were decreased. No significant differences in stipe thickness were observed. The ASI4065 and 4151 had the tallest stipe and the ASI4021 had the shortest stipe. The ASI4103 strain had the biggest pilus diameter. The ASI4153 had most thick pilus, while the ASI 4021 had least thick pilus. Also, the ASI4166 had the most thick stipe and the ASI4065 had the most thin stipe. The hardness of white mushrooms were increased by decreasing growth temperatures, while no relationships between the hardness of brown mushrooms. In most strains, stipe were much stronger than pilei and white mushrooms were harder than brown ones. The strain having most strong stipe was ASI4021. Both ASI 4021 and ASI4166 had the most strong pilus. The color of pilus has much lighter than that of stipe. White mushrooms had high brightness value ranging from 70-90, while brown mushrooms showed low brightness value from 30-70. Saturation value was higher in brown mushrooms. Based on our study, it was shown that environmental conditions had some effects on winter mushrooms, but genetic differences among strains were more important factors to determine most characteristics of winter mushrooms.
