The physiological activities of 70% ethanol extracts of grape seed (GS) prepared by freeze-drying (GSFD), infrared drying (GSIR), hot-air drying (GSHD), or sun-drying (GSSD) were investigated. The moisture contents of GSFD, GSIR, GSHD and GSSD powders were 4.53, 6.71, 6.91 and 5.55% respectively. Hunter’s color value analysis revealed that the L* value of GSIR was lower, and the a* and b* values of GSIR were higher, than those of GSFD, GSHD, and GSSD. The total polyphenol and proanthocyanidin contents of GSFD were significantly higher than those of the other extracts. The flavonoid related substance contents were in the order of GSFD (7.68 g/100g) = GSSD (7.59 g/100g) = GSHD (7.33 g/100g) > GSIR (6.45 g/100g). The electron donating abilities of 500 μg/mL solutions of GSFD, GSIR, GSHD and GSSD were 88.71, 52.62, 65.20, and 65.22%, respectively, while their reducing powers (OD700) were 1.633, 1.097, 1.217 and 1.054 absorbance units, respectively. Additionally, the same trend was observed for the ABTS radical-scavenging abilities of the extracts as that observed for their electron-donating abilities and reducing powers. These results suggest that GSFD is the best method for preparing GS extracts with enhanced antioxidant activities, and that GS extracts may be used as a natural antioxidant material for use in health foods.

In order to develop a sprayable ethylene antagonist, unlike 1-methylcyclopropene (MCP), we synthesized 2-decylcyclopropene-1-carboxylic acid ethyl ester (DCPE) as a derivative of cyclopropene and tested its effect on the flesh softening of ‘Fuyu’ persimmon fruits. The fruits on trees were sprayed with 4·10-4 M DCPE solution before harvest. After harvest, the persimmon fruits were stored at a low temperature for 1.5 months. The ripening progress of the fruits was then evaluated during storage at ambient temperature (20℃). Flesh softening, a measure of ethylene response, was considerably delayed up to 7 days after DCPE treatment. However control fruits was rapidly softened after 3-day storage. The treatment effect of DCPE at 4·10-4 M was also compared to that of 1-MCP at 1 ppm. DCPE was storable at refrigerated conditions for at least one month without any loss. The results show that DCPE could be a potential sprayable agent for the prevention of flesh softening of persimmon fruit.

This study was conducted to determine CO2 treatment condition to extend the shelf-life of ‘Seolhyang' strawberry. Fresh strawberries with red color on 80% of the fruit surface were harvested. The samples at two different stages (on the 1st and 3rd day after harvest) were placed in a gas-tight chamber with 0, 5, 15, or 30% CO2 concentration for 3 hours at 4℃. Then, the strawberry samples were immediately packaged in a PET tray and stored at 4℃. The carbon dioxide treatment was effective in maintaining the quality of ‘Seolhyang’ strawberries treated on the 1st day after harvest. These samples had higher firmness, lower redness, softening index, and decay rate compared to samples treated on the 3rd day after harvest. Treatment with both 15 and 30% of CO2 concentration on the 1st day after harvest induced an increase of firmness of ‘Seolhyang’ strawberry after the treatment. Samples treated with 15 and 30% CO2 the 1st day after harvest maintained quality for 10 days. However, samples treated with CO2 on the 3rd day after harvest lost marketability at 10 days of storage. At the atmosphere containing 30% CO2 on the 1st day after harvest was most effective in reducing decay rate and fruit softening, and maintaining bright red color of strawberries among different CO2 concentrations. Therefore, a 30% CO2 treatment within one day after harvest can be a practical postharvest technology to extend shelf-life of ‘Seolhyang’ strawberry.

In this study, the anti-inflammatory effect of hyaluronidase (HAase) inhibition was determined from 92 species of oriental herbal medicine extracted with water and ethanol solvents because of their non-toxicity in the human body. The water extracts of Evodia officinalis (86.8%), Thuja orientalis (80.8%), Carthami semen (66.5%), Melia azedarach (74.7%), Siegesbeckia pubescens (61.3%), Saururus chinensis (49.15%) showed a relatively greater anti-inflammatory activity. The ethanol extracts of Ailanthus altissima and Saururus chinensis demonstrated the highest anti-inflammatory effect at above 90%. Saururus chinensis was selected for its high anti-inflammatory effect in both water and ethanol extract. Ethanol was more effective than water and optimal extraction conditions for phenolic compounds was determined to be extraction with 50% ethanol for 12 hours. The extracts from Saururus chinensis in optimal condition showed 70~80% anti-inflammatory effect when 100~250 μg/mL phenolic concentration was treated. Concentration of above 500 μg/mL decreased the inhibitory effect. The anti-inflammatory effect and extraction yield were increased by ultra-fine grind technology, indicating that this method can be used to increase the extraction yield of phenolic compounds from medicinal plants.

This study investigated the effect of heat treatments on the quality characteristics of fresh-cut 'Romaine' lettuce by treating in hot water (45, 50, and 55℃) for 2 minutes. Sensory properties, respiration rate, ethylene production, microbial growth, browning index, total phenolics (TP), vitamin C, and antioxidant properties (DPPH, ABTS, and FRAP assays) of samples were evaluated after 5 days at 5℃. All heat treatment conditions tested in this study did not affect the change in TP after storage. Treatment at 45℃ enhanced respiration rate and ethylene production wheres decreased vitamin C content and antioxidant activities. There was no significant difference in browning index at 45℃ treatment. The rapid tissue softening occurred when treated with 55℃ hot water for 2 minutes. The 50℃ heat treatments exhibited the best quality index including texture and color, and inhibited microbial growth and browning after storage. In addition, the 50℃ heat treatment showed the highest vitamin C content and antioxidant activities (DPPH, ABTS, FRAP assay) after storage. Therefore, the 50℃ heat treatment can be used to maintain quality and antioxidant property of fresh-cut ‘Romain’ lettuce.

In order to investigate the utilization of the Omija (Schizandra chinensis Baillon) extract as a natural coagulant for manufacturing soybean curd, the quality characteristics of white (Baktae) and black (Seoritae) soybean curds, coagulated by the Omija extract or MgCl2, were evaluated. Crude protein (6.14±0.30 and 6.25±0.18%, respectively) and crude lipid (10.86±1.74 and 11.29±1.69%, respectively) contents of white and black soybean curds coagulated using the Omija extract were higher than those coagulated using MgCl2. Black soybean curds coagulated using the Omija extract showed higher L, a, and b values than those using MgCl2. The most abundant amino acid in white and black soybean curds coagulated using the Omija extract was arginine (3.74 and 3.71 mg/100 g, dry basis, respectively). The amounts of Ca, K, Mg, and Na were the highest in both soybean curds prepared with the Omija extract. The sensory evaluation (color, flavor, taste, texture, and overall preference) showed that white and black soybean curds coagulated using the Omija extract were more preferred than those produced using MgCl2. The results suggested that using the Omija extract as a natural coagulant agent could improve the quality and sensory characteristics of soybean curds.

This study analyzed the physicochemical characteristics of Astragalus membranaceus (AM) fermented with seven different mushroom mycelia. Physicochemical characteristics, such as contents of moisture, pH, total reducing sugars, free sugar, and isoflavonoid, were investigated. The moisture content was increased in most of the samples. The pH values of AM fermented with Phellinus linteus and Flammulina velutipes were increased, while the pH of other samples were similar to that of non-fermented AM. The reducing sugar content was in the range of 211.69~391.74 mg/100 g. The extraction yield using water was higher than that when extracted with 80% ethanol. The free sugar content was increased through fermentation with mushroom mycelia. However, the glucose contents of the 80% ethanol and water extracts were decreased. Finally, the calycosin and formononetin contents in 80% ethanol and water extracts of AM fermented with Phellinus linteus were 2,549.24 mg/g, and 827.66 mg/g for calycosin, and 1,366.69 mg/g and 221.28 mg/g for formononetin, respectively. These results suggest that fermentation with mushroom mycelia could be used to increase the bioactivity of AM. The mycelium-fermented AM might be a valuable source of functional material and edible resource for industry.

The volatile flavor components of the fruit pulp and peel of orange (Citrus sinensis) and grapefruit (Citrus paradisi) were extracted by simultaneous distillation-extraction (SDE) using a solvent mixture of n-pentane and diethyl ether (1:1, v/v) and analyzed by gas chromatography-mass spectrometry (GC-MS). The total volatile flavor contents in the pulp and peel of orange were 120.55 and 4,510.81 mg/kg, respectively, while those in the pulp and peel of grapefruit were 195.60 and 4,223.68 mg/kg, respectively. The monoterpene limonene was identified as the major voltile flavor compound in both orange and grapefruit, exhibiting contents of 65.32 and 3,008.10 mg/kg in the pulp and peel of orange, respectively, and 105.00 and 1,870.24 mg/kg in the pulp and peel of grapefruit, respectively. Limonene, sabinene, α-pinene, β-myrcene, linalool, (Z)-limonene oxide, and (E)-limonene oxide were the main volatile flavor components of both orange and grapefruit. The distinctive component of orange was valencene, while grapefruit contained (E)-caryophyllene and nootkatone. δ-3-Carene, α-terpinolene, borneol, citronellyl acetate, piperitone, and β-copaene were detected in orange but not in grapefruit. Conversely, grapefruit contained β-pinene, α-terpinyl acetate, bicyclogermacrene, nootkatol, β-cubebene, and sesquisabinene, while orange did not. Phenylacetaldehyde, camphor, limona ketone and (Z)-caryophyllene were identified in the pulp of both fruits, while α-thujene, citronellal, citronellol, α-sinensal, γ-muurolene and germacrene D were detected in the peel of both fresh fruit samples.

Eruca sativa (known as rocket plant) is a member of the Brassicaceae, which is considered an important chemo-preventive plant family. Although Eruca sativa has positive biological effects such as antioxidant and renal protective activities, the effect of the Eruca sativa extract as a therapeutic agent for skin whitening has not been reported. In this study, we investigated the applicability of the extract of Eruca sativa as a functional materials by examining the its physiological activities. The Eruca sativa extract showed low cytotoxicity against murine melanoma B16F10 cells. At concentrations (below 100 mg/L) that showed none or little cytotoxicity, the Eruca sativa extract showed high DPPH radical scavenging activity (ID50, 17.60 mg/L). In addition, the Eruca sativa extract inhibited tyrosinase activity (ID50, 132.54 mg/L) and decreased melanin content (ID50, 158.90 mg/L). Finally, the treatment with the Eruca sativa extract suppressed the protein expression of tyrosinase in a concentration-dependent manner. These findings suggested that the Eruca sativa extract inhibited melanin synthesis by not only suppressing intracellular tyrosinase expression but also directly inhibiting tyrosinase activity. Therefore, these results indicate that the Eruca sativa extract may be an effective material for functional cosmetics such as skin whitening materials.

Seven kinds (acacia, cochineal, catechu, grape peel, persimmon, gallnut and clove) of color powders obtained from natural resources and their mixtures were evaluated for their biological activities, such as antioxidant (ABTS and DPPH radicals scavenging), cholesterol absorption, and COX-2 inhibitory activities. Catechu, gallnut and clove were selected for the further studies due to its the best activities. The cholesterol absorption, COX-2 inhibitory, α-amylase inhibitory and α-glucosidase inhibitory activities were measured using the mixtures of catechu, gallnut and clove. The ABTS radical scavenging activity of the seven types of natural color powders were higher than the DPPH radical scavenging activity. The cholesterol absorption activity was significantly higher in cloves. The COX-2 inhibitory activity was significantly lower in acacia. The α-amylase inhibitory activity was higher in catechu and gallnut, indicating that there were no significant difference between two mixtures. The α-glucosidase inhibitory activity was the highest in catechu, which was higher than that of the catechu-containing mixtures. From all these results, a synergistic effect could be obtained when utilizing a mixture of powders rather than using only individual type. Since the activity of each powder was different, further studies will be required for clarifying the interactions between mixtures.

The antioxidant and digestive enzyme inhibitory effects of Eisenia bicyclis extracted by various extraction methods (RE, reflux extraction; SE, ultrasonification extraction; AE, autoclave extraction; LE, low-temperature high-pressure extraction) were investigated. The extraction yield (55.21%) and the laminarin (39.03%), fucoidan (24.75%), total polyphenol (115.68 mg GAE/g) and flavonoid (36.67 mg RHE/g) contents of AE were higher than those in other methods. The DPPH radical (86.60%, 500 mg%), ABTS radical (58.56%, 25 mg%), nitrite (86.38%, 100 mg%) scavenging activities of the Eisenia bicyclis extracted by AE were higher than those of Eisenia bicyclis extracted by other methods. The ABTS radical and nitrite scavenging activities were above 98% in all tested Eisenia bicyclis extracts and these activities were dependent on its concentration. The inhibitory effects of AE against amylase (50 mg%) and α-glucosidase (5 mg%) were 64.76% and 86.71%, respectively. The AE showed the best inhibitory effect of Eisenia bicyclis extracts (50 mg%) against trypsin (24.37%) and α-chymotrypsin (49.05%), respectively. These results suggest that Eisenia bicyclis extracted by AE can be used as a bioactive and functional material in the food industry.

The purpose of this study was to evaluate the inhibitory effect of commercial Makgeolli on tumor growth in human gastric adenocarcinoma cells (AGS) in a xenograft cancer model, transplanted with AGS cells. Commercial Makgeolli was first dealcoholized by evaporation and used as the test sample. We detected a significant increase in the volume and weight of tumor in nude mice (induction) that were transplanted with AGS cells. Administration of 100 mg/kg·day group (ML), and 500 mg/kg·day group (MH) dealcoholized commercial Makgeolli significantly decreased tumor growth. In this study, 5-FU 18 mg/kg·day was used as a positive control for tumor growth inhibition. Additionally, determination of the body weight of both the groups revealed no side effects after the administration of dealcoholized commercial Makgeolli. Using the cell culture system, we also evaluated the effect of dealcoholized commercial Makgeolli on caspase-3/7 activity in the AGS cells. Treatment with dealcoholized commercial Makgeolli increased the activation of caspase-3/7 and the apoptotic markers in AGS cells in a dose-dependent manner. Therefore, dealcoholized commercial Makgeolli can be used for cancer prevention.

In this study, the antioxidative activity and functional food activities of water and ethanol extracts from Pinus densiflora root were examined. It was more effective to use ethanol than water when extracting phenolic compounds. The extracted phenolic compounds from Pinus densiflora root for biological activities were examined. The phenolic compounds extracted with water and 80% EtOH were 1.86±0.04 mg/g and 6.85±0.16 mg/g, respectively. DPPH free radical scavenging activity of water and EtOH were each 86% and 85% at 100 μg/mL phenolics, respectively. ABTS radical decolorization activity was 48% in water and 68% in EtOH at 200 μg/mL. Antioxidant Protection Factor (PF) were 1.74 PF in water and 1.96 PF in EtOH at 50 μg/mL. TBARs of water and EtOH were 93% and 98%, respectively at 100 μg/mL. The inhibition activity on xanthine oxidase was 83.7% in water extracts and 79.6% in ethanol extracts. Inhibition on xanthine oxidase of water and ethanol extracts showed a higher inhibition effect than allopurinol. The inhibition activity on α-glucosidase was 14.8% in water extracts and 91.6% in ethanol extracts. The result suggests that P. densiflora root extracts may be useful as as functional food material.

This study was performed to provide information for improving the quality characteristics of tangerine peel Soksungjang. Tangerine peel Soksungjangs were prepared with 10% tangerine peel powder by addition of different koji such as Rhizopus oligosporus (RS, RTS) and Aspergillus oryzae (AS, ATS). As a result, the moisture content was not changed and crude protein content decreased during fermentation in all samples. The pH of RS (Soksungjang manufactured with Rhizopus oligosporus koji) and RTS (Soksungjang manufactured with Rhizopus oligosporus koji and 10% tangerine peel powder) was not changed, whereas pH of AS (Soksungjang manufactured with Aspergillus oryzae) and ATS (Soksungjang manufactured with Aspergillus oryzae koji and 10% tangerine peel powder) decreased rapidly after 10 days of fermentation. The acidity values of all the samples increased during fermentation. The major free sugars were glucose, fructose, and maltose; while, the major organic acids were citric acid, succinic acid, acetic acid, and lactic acid in all the samples. The amino nitrogen content and protease activity were highest in the AS and ATS. Conversely, the reducing sugar content and α-amylase activity were highest in the RS and RTS. The major free amino acids in all samples were glutamic acid, lysine, leucine, and arginine. Sixty kinds of volatile flavor compounds were identified from all samples; the majority of which were 21 alcohols, 14 hydrocarbons, 5 esters, and others identifies as acids, ketones, and aldehydes.

This study was conducted to investigate the change in the quality of early season Fuji apples that were subjected to eight different storage conditions using the developed controlled atmosphere (CA) storage system. Early season Fuji apples grown at Mungyeong, in the South Korea, were harvested in September 2014 for storage studies. Flesh firmness, titratable acidity, total soluble solid content, weight loss, and internal browning disorder were used as quality indicators for the stored apples. Flesh firmness and weight loss were better than that of the control after 70 days of storage. However, there was no significant difference in the titratable acidity or total soluble solid content among the apple samples from eight chambers after storage. The internal browning disorder of apple samples in CA chambers occurred when exposed to 1% CO2+2% O2 and 1% CO2+0.5% O2, resulting in a higher incidence rate of 2 and 8% after 70 days of storage than that in the control. In addition, the CA storage conditions at 3, 4 and 5% CO2+2% O2 increased the rate of internal browning disorder by 26%. Therefore, CA storage can be used to maintain the quality of the apple if the optimal gas concentrations in the CA are applied to the storage strategy.

This study investigated the effect of electron beam (EB) treatment on the microbial reduction of dried laver (Porphyra tenera) and identified EB-resistant bacteria from the treated dried laver. After EB treatments of 4 kGy and 7 kGy, the numbers of total bacteria and EB-resistant bacteria were measured using tryptic soy agar and mannitol salt agar, respectively. The morphological and biochemical characteristics of each isolated EB-resistant bacteria were investigated and these bacteria were identified. Compared to the control (1.5±0.2)×106 CFU/g, the total bacterial number was significantly decreased to (5.4±0.5)×104 CFU/g and (1.1±0.6)×104 CFU/g after EB treatments of 4 kGy and 7 kGy, respectively. With a higher EB dosage, the number of red colonies was almost same, whereas the number of yellow colonies was significantly decreased to (3.3±1.2)×103 CFU/g and 0 CFU/g for 4 kGy and 7 kGy, respectively. All red and yellow colonies were gram-positive cocci, catalase-positive, and resistant to 3% and 5% NaCl media. From the 16S rDNA sequence analysis, yellow and red colonies were identified as either Micrococcus flavus or M. luteus, with 99% similarity for the yellow colonies, and Deinococcus proteolyticus and D. piscis, with 99% and 97% similarity for the red colonies, respectively.
