  • This study was carried out to investigate the effect of the addition of lotus (Nelumbo nucifera) root and leaf powder on the quality characteristics of pork patties. The pork patties were of four types: nothing added (CTL), 0.5% lotus root powder added (LRP), 0.25% lotus root and 0.25% lotus leaf powder added (LRLP), and 0.5% lotus leaf powder added (LLP). There was no significant difference in $L^*$ value (whiteness), cohesiveness, gumminess, chewiness, water holding capacity, VBN content, and total bacterial amount. The moisture was highest in CTL, protein was highest in LRLP, fat was highest in LRLP and LLP, and ash was highest in LRLP (p<0.05). The total polyphenol content of the CTL, LRP, LRLP, and LLP were 3.34, 3.64, 3.90 and 3.90 mg/100 g, respectively. The $a^*$ value was highest in CTL, and the $b^*$ value of LRLP and LLP were higher than those of CTL and LRP (p<0.05). The hardness of CTL and LRP were higher than those of LRLP and LLP, and springiness was lowest in LLP (p<0.05). The cooking loss, thickness change, diameter changes, and pH were highest in CTL (p<0.05). The TBARS was highest in CTL, and was lowest in LLP (p<0.05).

  • This study was carried out to investigate the effect of safflower seed powder on the physicochemical characteristics of ground pork during refrigerated storage. Three types of ground pork were evaluated: 20% pork fat added (PF, control), 10% pork fat and 10% added safflower seed powder (PFS), and 20% added safflower seed powder (SS). The pH increased during storage, but decreased after 10 days of the storage (p<0.05). The pH was lower in PFS and SS than that in PF after 10 days of storage (p<0.05). The TBARS (2-thiobarbituric acid reactive substances) values increased with longer storage period (p<0.05), and those of PF, PFS and SS were 1.186, 0.686 and 0.577 mg MA/kg, respectively, after 10 days of storage. The $L^*$ values for external color of PF and PFS decreased (p<0.05), but that of SS was not significantly different after a longer storage period. The $a^*$ values decreased (p<0.05), but the $b^*$ values were not significantly different with longer storage period. The $L^*$ values for internal color of PFS and SS decreased (p<0.05), but that of PF was not significantly different with longer storage period. The $a^*$ value of PF decreased (p<0.05), but that of SS increased with longer storage period. The $b^*$ value decreased (p<0.05), but those of PFS and SS were not significantly different with longer storage period. Water holding capacity decreased with longer storage period, and that of SS was the highest (p<0.05). Cooking loss of PFS and SS was not significantly different with longer storage period, and that of PF was the highest (p<0.05). The reduction in diameter of the samples was not significantly different with longer storage period, and that of PF was the highest (p<0.05). Hardness and chewiness of samples increased, but springiness and cohesiveness decreased with longer storage period (p<0.05). Replacing animal fat with safflower seed powder was effective and may be useful as an innovative meat product.

  • This study was carried out to investigate the effect of the addition of safflower seed (Carthamus tinctorius L.) on the physicochemical properties of ground pork as an animal fat replacer. Three types of ground pork were evaluated: 20% pork fat added (control), 10% pork fat and 10% safflower seed powder added (10% SS), and 20% safflower seed powder added (20% SS). The moisture, protein, and ash contents were highest in 20% SS, and the fat content was highest in the control (p<0.05). The cooking yield, moisture retention, fat retention, and water-holding capacity were highest in 20% SS, and the control showed a reduction in the diameter (p<0.05). The external and internal L-, a-, and b-values of the control were higher than those of the 10% SS and the 20% SS (p<0.05). The cholesterol content of the control, the 10% SS, and the 20% SS was 50.85, 21.77, and 17.91 mg/100 g, respectively, and that of the 20% SS was lowest among the samples (p<0.05). The linoleic acid content of the control, the 10% SS, and the 20% SS was 28.68%, 41.04%, and 54.26%, respectively. The total unsaturated fatty acid content of the control, the 10% SS, and the 20% SS was 50.53%, 55.76%, and 64.93%, respectively. The linoleic acid and the total unsaturated fatty acid content were highest in the 20% SS (p<0.05). There was no significant difference in amino acid composition.

  • The effect of aeration process in causing changes in the prosapogenin content and the antioxidant activity of red ginseng powder extracts was investigated. With respect to the color change of the extracts, the L-value and b-value decreased significantly with the lapse of extraction time both with and without the aeration process. The a-value increased with the lapse of the extraction time in the non-aeration process but decreased in the aeration process. This result suggests that when the aeration process was performed, the lightness, yellowness, and redness decreased with the lapse of the extraction time, resulting in a darker color. The total polyphenolic and total flavonoid contents were the highest at 0.84 and 0.96 mg Gallic Acid Equivalent (GAE)/mL, 21.77 and 21.93 mg GAE/mL at 24 h and 36 h, respectively for the aerated red ginseng powder extracts. The DPPH, ABTS, H2O2 scavenging activity, and reducing power were measured to confirm the antioxidant effects of red ginseng powder extracts after the aeration process. Thus, the antioxidant activity was increased in the aerated red ginseng powder extracts. In addition, when comparing the contents of Rb1, Rg1, and Rg3, the content of Rg3 was significantly different, and it was confirmed that a large amount was produced in the aerated red ginseng extracts. These results indicate that the red ginseng extracts subjected to the aeration process are superior than the ones processed by the non-aeration process.

  • In this study, solubilized yuzu pulp powder (EYP) was produced using enzyme treated yuzu pulp powder (YP) and used to manufacture yuzu granules (0-20% EYP content). The physicochemical, product stability, and functional properties of Yuzu granules were compared among five enzyme treatments. Among the five treatments, CL had the highest YP solubilization yield (48.68%). Microstructural observation of EYP using FE-SEM revealed that its surface became irregular and porous after enzymatic treatment. Compared to YP, EYP had 2 times lower insoluble dietary fibers and 3 times lower hemicellulose and cellulose content. Among the yuzu granules, IV (yuzu granules with 15% EYP) had an excellent water and oil holding capacity and flowability. IV granule had the highest narirutin and hesperidin content of 3.4 mg and 2.2 mg/g DW, respectively and the highest antioxidant (68.4%) and tyrosinase inhibitory activities (82.5%). Therefore, EYP or granule with EYP can be used as a functional component in food industry or pharmaceutical field.

  • This study was carried out to investigate the quality characteristics of muffins with added Pholiota adiposa powder. Muffins were prepared with different amounts of Pholiota adiposa powder (in 0, 2.5, 5, 10, and 15% ratios to the flour quantity). For analyzing the quality characteristics during the manufacturing of muffins, the pH, moisture content, dough density, height, specific volume, baking loss, texture, color, antioxidant activity, total polyphenol content, and sensory test results were determined. As the Pholiota adiposa powder content increased, the moisture content of the muffins decreased from 26.72 to 22.56%. The hardness of the muffins was increased with increasing Pholiota adiposa powder content, with the muffins with 15% Pholiota adiposa powder the hardest among all the samples. The inner color of the muffins, particularly the L and b values, decreased with increasing powder content compared to those of the control, but the a value increased. As the Pholiota adiposa powder content increased, the antioxidant activity and total polyphenol content of the muffins also increased. In the sensory evaluation, the muffins with 5% Pholiota adiposa powder showed higher values than the control and the other samples in all aspects, showing that 5% Pholiota adiposa powder could be incorporated into muffins to meet the taste and functional needs of the consumers.

  • This study evaluated the quality characteristics for optimization of premix-type Buckwheat (Fagopyrum esculentum) Soksungjang (BS). First, according to the amount of salt (8, 10, 12%), coliform counts were not detected in BS with 10 or, 12% salt at 21 days and Bacillus subtilis HJ 18-4 as a starter at 7 days. Therefore, 10% salt with starter culture might be considered as suitable conditions for safety. Second, according to the ratio of water (1:1, 1:1.5, 1:1.8), BS prepared with the same weights of meju powder and water showed the highest aminotype nitrogen content (688.76mg%) at 35 days; thus, an adequate fermentation state was established at this condition compared to others. Third, according to the type of container (pot, plastic, glass), the aminotype nitrogen contents were higher in the plastic container and pot than in the glass bottle. Lastly, according to the batch size (1.25, 2.5 kg), the coliform of the 2.5 kg sample decreased faster than that of 1.25 kg samples at 14 days. These results suggest that BS prepared with the same ratio of water and meju powder fermented with HJ 18-4 as a starter and 10% salt in a pot, plastic container (3 weeks) and glass container (4 weeks) showed desirable fermentation qualities.

  • This study was peformed to determine the antioxidative, antimutagenic and cytotoxic effects of the natural seasoning using Lentinus edodes powder (NSLP) by DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical donating method, Ames test, and cytotoxicity, respectively. The scavenging effect on DPPH radical in ethyl acetate fraction of NSLP showed $155{\mu}g\;of\;RC_{50}$. The direct antimutagenic effects of ethanol extract and its solvent fractions of NSLP were examined by Ames test using Salmonella Typhimurium TA98 and TA100. In the Ames test, ethanol extract of NSLP alone did not exhibit any mutagenicity and most of the samples showed high antimutagenic effects against mutation induced by N-methyl-N'-nitro-N-nitroso guanidine (MNNG) and 4-nitroquinoline-1-oxide (4NQO). Ethyl acetate fraction of NSLP ($200{\mu}g/plate$) showed approximately 82% inhibitory effect on the mutagenesis induced by 4NQO against TA98 strain, whereas 84% and 80% inhibitions were observed on the mutagenesis induced by 4NQO and MNNG against TA100 strain. In anticancer effects of ethanol extract and its solvent fractions of NSLP against cancer cell lines including human lung carcinoma (A549), human breast adenocarcinoma (MCF-7), human hepatocellular carcinoma (Hep3B), human cervical adenocarcinoma (HeLa) and human gastric carcinoma (AGS) were investigated. The treatment of 1 mg/mL ethyl acetate fraction of NSLP showed strong cytotoxicity of 56.7%, 84.9%, 64.6%, 85.1% and 71.5% against A549, MCF-7, Hep3B, HeLa and AGS, respectively. In contrast 1 mg/mL treatment of NSLP extract and its solvent fractions had only $4{\sim}40%$ cytotoxicity on human transfomed primary embryonal kidney cell (293). From this result, it is suggested that NSLP is believed to have possible antioxidative, antimutagenic and anticancer capacities.

  • This study was conducted to confirm the application as ingredients of cosmetics through an examination of the function for anti-cancer and anti-microbial of the fraction isolated from Pyrus ussuriensis leaves. The dried leaf of P. ussuriensis were extracted with acetone-$H_{2}O$ (6:4, v/v), concentrated and fractionated with the upper layer of acetone on a separatory funnel. Each fraction was freeze dried, then a portion of acetone soluble powder was chromatographed on a Sephadex LH-20 column using a series of aqueous methanol as eluents and also used the MIC-gel using a series of aqueous methanol as developing solvent. The isolated compounds were identified by silica-gel TLC. The growth inhibition activity was measured using the MTT assay by the mouse meltioma (B16F10) cell. The cancer cell growth inhibition rate of fractions isolated from P. ussuriensis leaf was 80%. In anti-microbial activity test, the fraction of P. ussuriensis with 0.25 mg/disc resulted in the clear zone of 1.3 cm and 2 cm for Staphylococcus aureus and S. epidermidis of gram positive bacillus, respectively. In Escherichia coli of gram negative bacillus, the fraction with 0.5 mg/disc resulted in the clear zone of 1.1 cm~1.5 cm each fraction. From these results, we confirmed that acetate fraction of P. ussuriensis has a great potential as a natural ingredients with a anti-cancer and anti-microbial source.

  • The present study investigated the relationship between physical conditions and sensory properties of red pepper powder stored at different temperatures ($-20^{\circ}C$, $0^{\circ}C$, $20^{\circ}C$) and in different wrap materials (linear low density polyethylene, LLDPE; aluminum/linear low density polyethylene, Al/LLDPE). Red pepper powders with initial moisture contents of $17.35{\pm}0.32$% were not affected by the packaging material or storage temperature. Hunter a values of red pepper powder decreased while Hunter b values increased as storage temperature increased. There were no significant differences according to packaging materials. The American Spice Trade Association (ASTA) color value ($60.85{\pm}0.13$) significantly decreased with increasing temperature from $-20^{\circ}C$ to $20^{\circ}C$ ($21.70{\pm}0.06$ to $56.03{\pm}0.24$). The ASTA color value of samples packed with LLDPE ($21.70{\pm}0.06$) decreased more compared to samples packed with other materials. Further, capsanthin contents ($13.74{\pm}0.02$ mg/100 g) significantly decreased with increasing temperature from $-20^{\circ}C$ ($0.25{\pm}0.01$ to $0.28{\pm}0.01$ mg/100 g) to $20^{\circ}C$ ($0.13{\pm}0.01$ to $0.25{\pm}0.01$ mg/100 g). In the sensory evaluation of red pepper powder, overall acceptability was influenced by redness, yellowness, and pungency color. All physicochemical and sensory properties of red pepper powder were compared. Hunter a values, ASTA color values, and capsanthin contents were significantly associated with sensory preferences. In particular, ASTA color value showed a close relationship with color preference for red pepper (R2=0.922). Thus, we suggest that the preference for red pepper powder can be determined based on instrumental measurements of Hunter a values, ASTA color values, and capsanthin contents.
