Effects of mustard seed (Brassica juncea) on the preservation of soup for Naengmyon were investigated, and morphological changes of E. coli treated with extract of mustard seed were examined. Titratable acidity of soup for Naengmyon treated with mustard seed was higher than that of control at initial stage, but became lower than control after 24 hours of preservation. The number of bacteria and E. coli in soup for Naengmyon added with mustard seed was lower than that of control, and the more mustard seed was added, the less bacteria and E. coli were observed. The content of volatile basic nitrogen (VBN) increased during preservation of soup for Naengmyon. The VBN content of soup for Naengmyon added with mustard seed was higher than that of control, and the more mustard seed was added, the lower VBN was detected. Scanning eletron microscopys of E. coli treated with extract of mustard seed showed that cell surface was distorted with shrinked cell mass.

Effects of mustard seed(Brassica juncea) on the preservation of raw gizzard-shad slice were investigated, morphological change of Vibrio Parahaemolyticus treated with water-extract of mustard seed was examined, the results are as following. The pH of raw gizzard-shad slice soaked in water with mustard seed slightly increased during preservation, and the pH was in inverse proportion to the added amount of mustard seed. The number of bacteria and Vibrio of raw gizzard-shad slice treated with mustard seed were lower than control, and the higher the mustard seed concentration, the lower the number of bacteria and Vibrio. The TMA-N content of raw gizzard-shad slice gradually increased during preservation, and the TMA-N was in inverse proportion to the added amount of mustard seed. Scanning electron microscopy of Vibrio Parahaemolyticus treated with water extract of mustard seed showed that surface membrane was destroyed with expended ellipsoidal shape.

To investigate the food preservative effects of mustard seed(Brassica juncea), mustard seed were added to Kimchi. Titratable acidity of Kimchi treated with mustard seed was higher than that of non-treated control at initial stage, but it was lower than control after 2 days of fermantation. The number of bacteria and lactic acid bacteria increased rapidly at the initial stage of fermentation and reached plateau by 2 days of fermentation. The number of bacteria and lactic acid bacteria of Kimchi treated with mustard seed was lower than that of control, and the more mustard seed added the less bacteria and lactic acid bacteria were observed.

This study investigated the effects of mustard seed extracts on physicochemical and storage characteristics of dry-aged pork loin ham during the aging period. In experiment 1, antioxidant activity was assessed for mustard seed extracted with varying ethanol concentrations and the results showed high antioxidant activity at 25%, 50%, and 75% ethanol concentrations. In experiment 2, pork loin was treated with mustard seed extracts obtained using different ethanol concentrations: not treated (control), 25% (MS25), 50% (MS50), and 75% (MS75). Physicochemical and storage characteristics of pork loin ham were measured in wk 0, 2, 4, and 6. The pH, a_w, CIE b^*, thiobarbituric acid reactive substances and volatile basic nitrogen values were lower in treated samples compared to the control (p<0.05). In conclusion, applying mustard seed extracts, particularly MS75, in the dry-aged pork loin ham production process could enhance storage stability and improve color attributes without having negative impacts on product quality.

To investigate the antimicrobial activities of mustard seed(Brassica juncea), a series of solbents were examined for extraction of antimicrobial substances from mustard seed and then antimicrobial substances were identified by simultaneous distillation extraction(SDE) and GC-MS methods. Water and methanol extracts of mustard seed showed antimicrobial activitries against experimental strains while those from hexane extract almost was not observed. The distilled components of mustard seed by SDE method showed strong antimicrobial activities, methanol extract of residues fraction exhibited a little, and water layer with the exception of distilled components showed no antimicrobiol activities. The 30 varieties of distilled components including 3 types of isothiocyanate such as 3-isothiocyanate-1-propene, 4-isothiocyanate-1-butene, and 3-isothiocyanatoethyl benzene were identified from mustard seed.

Seed mustard is high in nutrient quality and grows continuously under cold condition. Accordingly, it possessess high potential to bring about more efficient use of land when it is grown as a seasonings crop at paddy field in winter season. Recently, Seed mustard has aroused people‘s interest as a catch crop. The purpose of this trial is to examine productivity and chemical components of seed mustard and to select suitable variety in the southern area of Korea. Seed-mustard cv. Yeongsanpo local showed higher seed yield than any other varieties used in the experiment. It showed relatively high content of Oil, Protein, Ash, Carbo, $P_2O_5$, $K_2O$, Ca and T-N. The heritabilities of all the characters were estimated to be high. Therefore, it was concluded that Youngsanpo local was the most suitable variety with high yield and high nutrient quality at the southern area of Korea.

This study compared the nutritional value of canola (B. napa) and mustard (B. hirta) press cakes obtained from the biodiesel industry as ingredients for use in diets fed to broiler chickens. A total of 210, one-day old, male broiler chicks were randomly assigned to one of seven dietary treatments. The control diet was based on wheat and soybean meal and contained 15% canola meal. For the experimental diets, 5, 10 or 15% of the canola meal was replaced with an equal amount of either canola or mustard biodiesel press cake. Dry matter and neutral detergent fiber digestibility were significantly higher for birds fed diets containing either canola or mustard biodiesel press cake compared with canola meal. Dry matter and neutral detergent fiber digestibility of the canola biodiesel press cakes was higher than the mustard biodiesel press cakes. Ether extract digestibility and nitrogen retention were significantly higher for birds fed canola biodiesel press cake compared with canola meal and mustard biodiesel press cake. Body weight gain and feed intake did not differ between birds fed canola or mustard biodiesel press cake and canola meal. In addition, there was no significant difference in body weight gain or feed intake between birds fed diets containing canola or mustard biodiesel press cake. Feed conversion was significantly improved for birds fed either canola or mustard biodiesel press cake compared with canola meal. Mortality was unaffected by treatment. Since the performance of broilers fed canola biodiesel press cakes was essentially the same as that of broilers fed canola meal, it is difficult to justify a premium to be paid for canola biodiesel press cake over that paid for canola meal. In addition, there was no difference in the performance of broilers fed biodiesel press cake obtained from canola or mustard seed. As mustard seeds are generally available at a lower price than canola seed, there may be some incentive to use mustard rather than canola seed for producing biodiesel press cake for use in poultry production.

This study investigated the effect of yellow, black, and brown mustard seeds on color, lipid oxidation (thiobarbituric acid-reactive substances [TBARS]), and microbiological and sensory qualities of meatballs during storage. Heat treatment of mustard seeds affected the TBARS value of meatball samples (p<0.0001). The addition of mustard seeds decreased TBARS value of meatball samples (p<0.0001). Heat treatment of mustard seeds decreased the $L^*$, $a^*$ and $b^*$ values of meatball samples (p<0.0001). The meatball samples with mustard seeds increased $b^*$ value of meatball samples however it decreased $a^*$ value of meatball samples (p<0.0001). The addition of mustard seeds decreased aerobic mesophilic bacteria count (p<0.0001), Enterobacteriaceae count (p<0.0001), psychrophilic bacteria count (p<0.0001) and yeast and mold count of meatball samples (p<0.0001). On a given storage day, the yellow mustard added meatballs sample was given higher color, appearance, flavor, acceptability ratings than those added black and brown mustard. Regarding sensory and microbiological properties, mustard seed contributed to microbiological quality and sensorial properties of meatball samples.

Investigations of the effects of pickle product ingredients on lipoxygenase (LOX) and methemoglobin (MHG, a nonenzymatic oxidant) catalyzing oxidation of linolenic acid were conducted. In addition, activities of LOX, peroxidase (POD) and catalase (CAT) in dry spices used in pickle products were determined. Some commercial pickle brines were observed to inhibit oxidation of linolenic acid by LOX and MHG. The ingredients in pickle products, such as dill oil emulsion, onion concentrate, oil cassia, polysorbate 80 and turmeric acid, reduced LOX and MHG catalyzed oxidation. Lipoxygenase activity was present in garlic, mustard seed and red pepper. Only in mustard seed, peroxidase activity was observed. Catalase activity was observed in garlic, black pepper, allspice and red pepper.
