This study was conducted to investigate the physical and sensory properties of ice cream containing fermented pepper powder. Three ice cream formulas were manufactured: 1, control; 2, supplemented with 0.1% fermented pepper powder; and 3, supplemented with 0.2% fermented pepper powder. Formulas 2 and 3 had significantly higher viscosity and lower overrun than formula 1 (p<0.05). Additionally, ice creams supplemented with fermented pepper powder were harder and maintained their forms longer than the controls. 0.2% fermented pepper powder added ice cream had no pungency as much as that of control and overall sensory attribute was not significantly different from control. Therefore, ice cream containing fermented pepper powder maintained physical and sensory properties similar to the controls, and maintenance was better. It means fermented pepper powder ice cream can be utilized as the material of functional food (dessert).

This study was carried out for the purpose of inquiring into the effects on shelf-life, quality characteristics, and antioxidant activities, of Majakgwa. This study also regards to the use fermented turmeric powder at varying concentrations in the recipe. The proximate composition of fermented turmeric powder, crude fat, carbohydrate, crude protein, and crude ash was decreased. Viewed division compared to the freeze-dried turmeric curcumin content was increased during fermentation due to the increase of mineral content. With an increased of the amount of fermented turmeric powder used in Majakgwa recipes, the pH of the dough was higher than that of the controlled group. The acid value of Maejakgwa was lowered down, and most effectively controled when adding Turmeric power by 3~6%, and the peroxide value shows high antioxidant ability from the initial storagr period when adding 6%. TBA value appears to have the highest antioxidant ability, when adding 6%, showing lower increasing rate than that of sample group added 0~3% Turmeric powder. When added 9% or more, however, it shows higher TBA value comparing with normal Maejakgwa, the reference group, which indicates on the contrary that the antioxidant ability is lowering. The bitter taste, exterior color, incense of Turmeric, solidity, and crispy level of Maejakgwa with fermented Turmeric powder have been increased significantly as per increase of fermented Turmeric powder, and the sample group added with 9% have shown the best result in the overall taste level. It is anticipated that adding 6~9% of fermented Turmeric powder can increase the storage capability to give the best taste level and effective antioxidant ability by minimizing the off-flavor and bitter taste, through the research as above, which would be the most appropriate blending ratio of Turmeric powder for producing Maejakgwa.

The effects of fermented garlic powder on production performance, egg quality, blood profiles and fatty acid composition of egg yolk in laying hens were studied in a 35-d experiment. Two-hundred and forty (ISA brown) layers aged 41 weeks were randomly allocated into the following four treatments: i) CON (basal diet); ii) G1 (CON+fermented garlic powder 1.0%); iii) G2 (CON+fermented garlic powder 2.0%) and iv) G3 (CON+fermented garlic powder 3.0%). There were no differences (p>0.05) among treatments in egg production, egg weight, eggshell breaking strength and eggshell thickness throughout the whole experimental period. However, yolk height was increased significantly (p<0.05) by the addition of fermented garlic powder during the 5th week while yolk color was greater (p<0.05) in G2 and G3 than in CON and G1 in the 5th week. Compared with CON, Haugh unit was increased (p<0.05) in response to fermented garlic powder treatments during the 5th week. No significant effects on total protein, albumin and IgG were observed in response to any of the treatments over the experimental period (p>0.05). There was a significant (p<0.05) reduction in plasma cholesterol concentration when the dietary level of fermented garlic powder was increased from 0.0 to 3.0%. The levels of saturated fatty acids (SFA) were significantly decreased (p<0.05) in response to G2 and G3 while monounsaturated fatty acids (MUFA) were higher (p<0.05) in G2 and G3 treatment groups than in CON and G1. Compared with other treatments, polyunsaturated fatty acids (PUFA) and PUFA:SFA ratio were higher (p<0.05) in G3. In conclusion, this study demonstrated that addition of fermented garlic powder reduced plasma cholesterol concentration and did not cause adverse effects on production performance. Moreover, addition of 3.0% garlic powder decreased SFA but increased PUFA and PUFA:SFA ratio in egg yolk.

The aim of this study was to investigate biological activity and biochemical properties of extracts from Bacillus subtilis-fermented silkworm (Bombyx mori L., SP) powder of different origin (Buan, Namwon, and Boeun). An additional aim was to determine the inhibition of cancer cell (B16-F10, HT-29, LNcaP, and MCF-7) proliferation and nitric oxide (NO) production from lipopolysaccharide (LPS)-induced RAW264.7 cells. Biological activities (${\alpha},{\alpha}^{\prime}$-diphenyl-${\beta}$-picrylhydrazyl [DPPH], free radical scavenging activity, fibrinolytic activity, antiproliferation activity, and anti-inflammatory activity) and biochemical properties (compositional amino acid contents, and mineral contents) were examined in water extracts from silkworm powder and B. subtilis-fermented silkworm powder. The highest amino acid contents were detected in Buan silkworm powder (BU). After fermented, the highest contents were found in B. subtilis-fermented Buan silkworm powder (BBO). The major minerals detected were K, Ca, and Mg. Rates of these minerals, especially those of Na increased after fermented. DPPH radical scavenging activity and fibrinolytic activity were stronger in the fermented group than non-fermented group. DPPH radical scavenging activity and fibrinolytic activity were highest in the extract from BBO. The inhibition activities of LNcaP and MCF-7 cells viability were significantly decreased in the BBO, and there was no inhibition activity in other cancer cells (B16-F10 and HT-29). An SRB assay of the cell viability of RAW 264.7 cells exposed to extracts of silkworm powder and B. subtilis-fermented silkworm powder revealed no toxicity in any of the groups. Compared with the LPS-treated group, the biggest reduction in NO production was detected in the BBO group. Based on these results, extracts from Boeun silkworm powder fermented with B. subtilis could be a candidate material as a dietary supplement for use in healthy functional foods.

Background: Excessive alcohol consumption is at the root of serious social problems such as hangovers, liver dysfunction, and alcoholism. Objectives: This study was carried out to determine the hangover ameliorating effect of fermented rice extract and a combination of yeast-fermented powder and lysate containing aldehyde dehydrogenase (ALDH) (improved new ingredients) in an ethanol-induced rat study. Methods: The concentrations of alcohol, acetaldehyde, and malondialdehye in serum were evaluated to assess the anti-alcohol and anti-aldehyde hangover effect in two experiments, one with fermented rice extract) and a second with yeast-fermented powder and lysate, using animal studies. Results: Experiment 2 with yeast-fermented powder and lysate containing ALDH showed similar and higher activity, respectively, in reducing ethanol and acetaldehyde concentration compared with Experiment 1 with fermented rice extract. Experiment 2 also significantly reduced malondialdehyde, a type of lipid peroxide. The ALDH-related compound (ARC) lysate showed better hangover relief effect than ARC powder. Conclusions: These results indicate that ALDH-related compounds exhibit a hangover relief effect, and fermented lysate is considered to be a better candidate for hangover relief.

The present study was designed to determine the physicochemical properties of yam (Dioscorea) solution fermented by L. bulgaricus, the protective effect of fermented Dioscorea opposita Thunb. on stomach lesions, and the possibility of its application to fermented dairy products. When the concentration of yam increased, the pH increased in raw powder samples but not in extracted powder samples. In 6% raw powder containing the sample, the viable cell counts showed a dramatic increase, whereas those in extracted yam powder significantly decreased in all concentrations during 32 h of fermentation. The viscosity of extracted yam powder showed a lower value than that of raw powder, which was maintained throughout the fermentation. The solution of Dioscorea opposita Thunb. raw powder showed a significantly higher allantoin content compared with the extracted powder (p<0.05). At 2% of added Dioscorea opposita Thunb., 0.65 mg/mL was contained in both samples; however, when 6% of Dioscorea opposita Thunb. was added, the amount of diosgenin increased up to 1.9 mg/mL. When 200 mg of powder/kg body wt. was injected, gastric lesions were apparently reduced compared with those of control rats. With 100 mg/kg body wt. injected into rats, the protective effect was a little lower than that in 200 mg/kg body wt. Based on these data, the present study indicated that yam powder fermented by L. bulgaricus showed a protective effect on gastric lesions in rats; therefore, it may be included as an added ingredient in yogurt manufacture.

Insects have been proposed as new protein sources for human nutrition, and protein availability is affected by insect characteristics. Fermentation can be used to obtain a variety of insect-based ingredients and products with unique properties, but its effect on protein availability is unknown. Fermented cricket (Gryllus bimaculatus) powder consists mainly of protein, and its oral administration has been reported to improve hair growth in androgenetic alopecia. The purpose of this study was to evaluate the hair-promoting activity of fermented cricket powder in an animal model using male C57BL/6 mice (25-30 g). The abdominal hair of the mouse (2x2.5 cm) was gently removed, and the groups fed as follows: Intact controls (no cricket powder); cricket powder only; and fermented cricket powder only. Food was applied daily for 11 weeks. Observational and physical examinations were performed and the results of the different groups compared. The application of fermented cricket powder significantly (p<0.01) promoted hair growth compared to the intact controls. The C57BL/6 results confirmed increased growth after seven weeks when the proportion of anagen follicles had increased by about 125% and 120% in the control and cricket powder groups, respectively. In conclusion, fermented cricket powder can be seen as a promising alternative alopecia treatment because it promotes hair growth, and, given the powder's composition, trace elements such as amino acids may have contributed to these effects.

The comparative effects of the fibrinolytic action, antioxidative activity, and tyrosinase inhibition of Cordyceps militaris powder and fermented Cordyceps militaris powders were investigated using several microscopic organisms. The nutritional components such as phenolic compounds, flavonoids, and minerals were also measured. The total phenolic compounds and flavonoid concentrations were highest in the Cordyceps militaris powder fermented by Aspergillus oryzae. Major minerals were K, Ca, Mg, and Zn. Native polyacrylamide gel electrophoresis (native-PAGE) analysis of the total protein patterns of Cordyceps militaris powder and fermented Cordyceps militaris powders revealed slight varietal differences. Fibrinolytic activity was highest in the Cordyceps militaris powder fermented by Bacillus subtilis and Aspergillus kawachii. The DPPH radical scavenging activity was slightly stronger in the powder fermented by Monascus purpureus; however, these samples all exhibited a relatively low activity when compared with butylated hydroxytoluene (BHT). Tyrosinase inhibition activity was stronger in the powder fermented by Aspergillus oryzae than in unfermented powder. These results may provide basic data for understanding the biological activities and chemical characteristics of Cordyceps militaris powder fermented by several microscopic organisms for the development of functional foods.
