The aim of this study was to evaluate the quality characteristics, antioxidant activities, and sensory properties of macaron with cabbage powder (CP). Physicochemical and sensory properties of macaron with different amounts (0%, 1%, 3%, 5%, and 7%) of CP were examined. The quality of macarons was evaluated based on spread factor, baking loss rate, color, texture, antioxidant activities, and sensory evaluation. As amount of CP addition increased, spread factor, baking loss rate, and L and a values decreased, whereas b value increased (p<0.05). For texture properties, hardness, cohesiveness, and springiness were increased by addition of CP (p<0.05). The gumminess and brittleness did not show significant changes up to 3% CP addition although significant changes in 5-7% CP addition (p<0.05) were evident. The total polyphenolic contents, DPPH radical scavenging activities, and reducing power were significantly increased by addition of CP at high concentrations (p<0.05). In the consumer acceptance of macarons, 3% CP showed the highest in color, flavor, texture, and overall acceptance and 5% CP showed the highest in taste. Meanwhile, macaron containing 7% CP showed the lowest scores in texture and overall acceptance (p<0.05). These data suggested that adding 3% of CP was the optimal concentration for making macaron.

A cultivar (Malus domestica cv. Fuji) of apple was selected to make apple peel (AP) powder by three different powdering methods. Frozen AP was thawed and subsequently was dried or ground without drying. After AP was dried by hot-air drying at 60°C or freeze-drying, the dried AP was ground using a conventional blender. Separately, the thawed AP was powered by using a cryogenic micro grinding technology (CMGT). The ground AP and three types of AP powder were extracted using deionized water, 20, 40, 60, 80, or 100% methanol, followed by vacuum evaporation. The total phenolics contents (TPC), total flavonoids contents (TFC), DPPH, and ABTS radical scavenging capacities of each extract were compared to determine an efficient powdering method. Lyophilized AP powder extract using 60% methanol showed the highest TPC and DPPH radical scavenging capacity. In contrast, 60% methanol extract of the powder by CMGT, resulting in the smallest particle, exhibited the highest TFC and ABTS radical scavenging capacity. This study suggests that the extraction yield of bioactive compounds from AP may be varied according to different powdering methods and that a new powdering process such as CMGT may be applicable to develop functional foods efficiently.

This study was conducted in an effort to investigate the effect of Maillard reaction products (MRPs) on enzymatic browning of burdock and their anti-oxidant activity. The MRPs were prepared by heating glucose and amino acids at 90°C, which served to produce a strong inhibitory effect on burdock polyphenol oxidase. As the reaction time of the solution containing glucose and amino acid increased at 90°C, the production of MRPs increased and intensity of the brown color deepened. When MRPs were prepared by heating at 90°C for five hours, the absorbance of MRPs from glucose and lysine was 6.44, while those of glucose and glycine was 1.95. The MRPs synthesized from the glucose and lysine also reduced the pH of MRPs from 5.60 to 4.51, but those from glucose and glycine decreased slightly from 5.57 to 5.33. The Michealis-Menten constant value (Km) of burdock PPO with pyrocatechol as a substrate was 16.0 mM, and MRPs were a non-competitive inhibitor against burdock PPO. The anti-oxidant activity of MRPs was measured by evaluating its radical scavenging activities of DPPH radicals, ABTS radicals and reducing power. The color intensity of MRPs produced by lysine and glucose were deeper than that produced by glucose and glycine. It was also found that MRPs produced from glucose and lysine exhibited stronger anti-oxidant properties than those produced by glucose and glycine.

We examined the quality characteristics of pound cake with prepared Aronia melanocarpa powder, which included the physical characteristics, antioxidant activity and sensory evaluation in this study. Pound cakes were prepared with various ratios of Aronia powder (0, 5, 10, 15, 20%). No significant difference in loss rate or weight was found from increased Aronia powder concentration. The color of pound cake was darker and reddish with the addition of Aronia powder. Lightness (L) and yellowness (b) significantly decreased with the addition of Aronia powder, whereas redness (a) increased (p<0.05). the qualities of hardness, cohesiveness, gumminess and chewiness of the pound cake prepared with the addition of Aronia powder were significantly increased when compared to control(p<0.05), with exception of 20% addtion. Total phenolic contents and DPPH radical scavenging activity was significantly elevated by the addition of Aronia powder(p<0.05). The pound cake with 10% Aronia powder showed the strongest positive sensory properties with regard to taste and overall palatibility. These results suggest that the addition of 10 % Aronia to pound cake batter could well serve to improve the overall quality, texture and taste of the final product.

The IC50 for ABTS radical scavenging ability was 0.070±0.00 mg/mL for Nypa fruticans Wurmb flower stalk, 2.918±0.13 mg/mL for blueberry, and 4.131±0.24 mg/mL for ginseng. For this reason, it is considered that containing plenty of polyphenol and antioxidant, Nypa fruticans Wurmb is related to antiinflammation. This research will contribute to production of functional foods and high value materials using Nypa fruticans Wurmb.

In order to verify the quality characteristics of soybean milk added chickpeas, the following characteristics were investigated: pH, solid contents, color, DPPH radical scavenging, as well as electric nose and sensory evaluation. Physicochemical and the sensory characteristics were analyzed based on the experimental data. The pH value was different in the control and the treatments (p<0.005). As the quantity of chickpea content increased, the solid content was augmented (p<0.0001). The L value was 56.86 in the control, and with the amount of chickpea addition increasing, the L value increased to 57.43 in 100% chickpea soybean milk (p<0.0001). The a value and b value also increased significantly (p<0.0001). However, the DPPH radical scavenging in the control was the lowest but the antioxidant activity of 100% chickpea milk was more than 2.5 higher than that of the control (p<0.0001). In the electric nose experiment, the flavor component of 20%, 30% and 100% chickpea treatment showed a significant difference compared to the control in the flavor components. In the sensory evaluation, for the score of flavor (p<0.001) and taste (p<0.0001), the score was higher in the treatments where 20% and 30% of chickpeas were added. In the sensory test of texture, there was no significant difference in the different experimental conditions except for the 100% chickpea addition treatment. In the overall acceptability test, the scores of 20% and 30% chickpea treatment were the highest results, compared to other treatments (p<0.0001). According to the correlation analysis, both antioxidant activity (0.797) and solid content (0.834) had shown high correlation to pH among the physiochemical characteristics (p<0.01). In the sensory evaluation, color, flavor, taste, texture and overall acceptability had shown a positive correlation to the amount of the soy bean milk added chickpea (p<0.01). In particular, the overall acceptability had shown the highest correlation to the taste (0.803), and it was the texture which resulted in the next highest correlation for overall acceptability (0.666).

This study was performed to determine the effects of different processing methods (AD: drying at 50°C for 15 h; ADR: roasting after drying; SAD: drying after steaming; SADR: roasting after steaming and drying) on the quality characteristics, total phenolic content, anthocyanin content, DPPH radical scavenging activity, and reducing powder of red radish (Bordeaux and watermelon radish) tea. The pH of red radish tea was the highest with SAD. In terms of the total sugar content, Bordeaux radish tea showed the highest level with AD, ADR, and SAD, and watermelon radish tea showed the highest level with SADR. The a value of Bordeaux radish tea was higher with AD and ADR. The b value of Bordeaux radish tea was increased with steaming and roasting treatment. In terms of measuring the colors of watermelon radish tea, the L value was decreased while the b value was increased with roasting treatment. The total phenolic content, DPPH radical scavenging activity, and reducing powder with ADR and SADR were higher than those in samples prepared by different processing methods. AD and SAD resulted in higher anthocyanin contents than ADR and SADR. In terms of sensory evaluation, the appearance and color were rated higher with AD and SAD, whereas the flavor and taste were ranked higher with ADR and SADR than in the other samples. The results suggest that red radish (Bordeaux and watermelon radish) tea prepared by ADR and SADR processing methods can be utilized as health functional tea material with antioxidant activity.

The insects have been investigated as novel sources for foods and biomaterials in several recent studies. However,its effects on hair growth have not been sufficiently researched. To develop novel and natural materials for preventingalopecia and promoting hair growth, we investigated the antioxidant activity and hair growth promoting effect of Tenebriomolitor larvae extract (TME). As a result, DPPH radical scavenging activity was 81.17%, and nitrite scavenging activitywas 43.69%, which were similar to blueberry extract. And TME promoted the proliferation of human DPCs and NIH3T3cells, concentration dependently. In addition, the TME prevented not only DHT-induced DPCs cytotoxicity but also actionof TBM as a potassium channel blocker in NIH3T3 cells. These results suggest that TME can be used as a functionalmaterial for alopecia therapeutic reagent by preventing hair loss and promoting hair growth.

The antioxidant and antitumor properties of natural products, often recognized in traditional medicine systems, represent therapeutic modalities to reduce or prevent uncontrolled oxidation processes which in turn potentially ameliorate or tumor based symptoms of chronic diseases. We have studied the antioxidant and antitumor effects of Amanita muscaria (A. muscaria) in vitro and examined whether the A. muscaria has synergistic effects on antioxidant and antitumor properties. Although A. muscaria induced a dose-dependent increase in antioxidant activity, the latter has a consistently higher antioxidant effect. In mouse monocytes, the lipopolysaccharide- (LPS-) induced tumor necrosis- (TNF-) synthesis was significantly inhibited by A. muscaria in a dose dependent manner and synergistic effects were clearly demonstrated with the A. muscaria on TNF- inhibition. A. muscaria effect was also evident on inhibition of nuclear factor-kappa B activity, cyclooxygenase-II activity, and lipid peroxidation in mouse monocytes. This presented results may be a starting point for a comprehensive characterization of biological effects of A. muscaria.

The purpose of this study was to expand the utility of the Polygonum multiflorum. Also, we fermented P. multiflorum by mushroom mycelial, and analyzed for chemical compositions and biological active of fermented P. multiflorum root. The crude protein content did not show a significant difference between control and fermented P. multiflorum root, crude fat, ash and crude fiber content of fermented P. multiflorum root were lower than control. The content of soluble nitrogen free extract of P. multiflorum root was significantly higher than fermented P. multiflorum root. The major amino acids of P. multiflorum root were determined the arginine. The content of arginine and glutamic acid were 586.67 mg%, and 283.78 mg%, respectively. Sixteen kinds of amino acids were detected in fermented P. multiflorum root, and the major amino acids were determined the arginine and threonine. The total amino acid contents of control and fermented P. multiflorum root were 3,469.03 mg%, and 3,630 mg%, respectively. As the results of antioxidant activity test, the antioxidant capacity of fermented P. multiflorum had a higher than the control. As the mushroom fermentation progresses, it is confirmed that the amino acid content and antioxidant capacity were increased, and it is expected to develop the product using the fermented P. multiflorum using mushroom mycelials.
