  • This study aimed to evaluate the effects of dietary microbial-fermented molasses on egg production and egg quality in laying hens.In total, 90 Hy-line Brown laying hens were divided into two treatment groups (control and 1% microbial-fermented molasses)with three replicates of 15 birds each. During the experimental period, supplementation of hen diets with 1% microbial-fermented molassesdid not influence egg weight, hen-day egg production, egg mass, and feed conversion ratio (p > 0.05), except for feed intake. Regarding egg quality, diets containing 1% microbial-fermented molasses significantly affected eggshell thickness, Haugh unit, and albumen height (p < 0.05). However, there were no remarkable differences between control and 1% microbial-fermented molasses in eggshell color and egg yolk color (p > 0.05). These results indicate that supplementing 1% microbial-fermented molasses to the diet of laying hens improved egg quality parameters such as eggshell thickness, Haugh unit, and albumen height rather than egg production.

  • Indigenous fermented foods have played a vital role in human history, and continue to offer a multitude of diverse sensory characteristics. According to earthenware relic, the fermented fisheries products might be consumed in Korean peninsula from Paleolithic period. The traditional Korean fermented fish products are classified into four groups; Jeot-gal (sik-hae), Aek-jeot, Seasoned Jeot-gal, and Seasoned Aek-jeot. Jeot-gal is a fermented fishery with salt. Aek-jeot is a liquid part of Jeot-gal. Sik-hae is manufactured by fementing fishery with salt, cereal, malt powder, etc. Seasoned Jeot-gal is a salt-seasoned fish with red pepper powder, garlic, onion, etc. Seasoned Aek-jeot is a seasoned product by adding "salt-water" or "condiment" to Aek-jeot. The fermented fisheries industry has traditionally been succeeded mainly in a cottage scale to the middle of 20th century. Thereafter, together with the development of pelagic fishery, the fermented fisheries industry also developed constantly to an enterprise size.

  • This trial was performed to study the effects of replacing soybean meal (SBM) with fermented rapeseed meal (RSM) on growth performance, serum biochemistry variable and intestinal morphology of broilers. A total of 640 d-old Arbor Acres broiler chicks were randomly allocated to 4 dietary treatments, 4 pens per treatment and 40 birds per pen for a 6-wk feeding trial. In the four treatment groups, fermented RSM replaced soybean meal at 0, 5, 10, and 15%, respectively. On 21 d and 42 d, two birds from each pen were randomly selected and slaughtered. Blood samples and sections of duodenum, jejunum, and ileum were collected for measurement of serum biochemical variables and intestinal morphology, respectively. Results showed that body weight gain (BWG) and feed conversion (FC) were significantly (p<0.01) poorer for birds fed the 15% fermented RSM diet than those fed with 0, 5 and 10% fermented RSM diets during all periods. Compared with 0 and 5% fermented RSM groups, IgG content in the serum of birds in 10 and 15% fermented RSM groups was improved (p<0.01) urea nitrogen content of serum was reduced (p<0.01) during both growing and finishing periods. However, IgM, phosphorus and calcium levels increased (p<0.05) only during the growing period. Increased (p<0.05) villus height was observed in the duodenum and jejunum of broilers fed the diet with 10% fermented RSM. In addition, villus height to crypt depth ratio in the jejunum was significantly higher (p<0.01) for birds fed the diet with 10% fermented RSM than for those fed diets with 0, 5 and 15% fermented RSM. The present results suggest that RSM fermented with Lactobacillus fermentum and Bacillus subtilis is a promising alternative protein source and that it could be safely used replace up to 10% SBM in broiler diets.

  • There were fifty two kinds of fermented soybean sauce before 17th century thirteen recorded in ${\ulcorner}$Sangayorock${\lrcorner}$, two in ${\ulcorner}$Sasichanyo${\lrcorner}$, one in ${\ulcorner}$Yongjechongwha${\lrcorner}$, nine in ${\ulcorner}$Soowonjabbang${\lrcorner}$, one in ${\ulcorner}$Domoondaejak${\lrcorner}$, six in ${\ulcorner}$Dongyoebogam${\lrcorner}$, four in ${\ulcorner}$Gushangchalyo${\lrcorner}$, five in ${\ulcorner}$Guhwangboyubang${\lrcorner}$, two in ${\ulcorner}$Yorock${\lrcorner}$, four in ${\ulcorner}$Chisengyoram${\lrcorner}$ and five in ${\ulcorner}$Joobangmoon${\lrcorner}$. These books had thing to know when making fermented soybean sauce like kinds of soybean sauce, how to make it, its ingredients and quantities to be used, how to make fermented soybean sauce in haste, and how to remake wrong made fermented soybean sauce, etc. Before 17th century, fermented soybean malt was divided into two kinds the only soybean malt and the mixed soybean malt that had bean, wheat, wheat flour and wheat bran. The bean only soybean malt was further divided into mashed soybean malt (Beans were steamed and mashed into past.) and unmashed soybean malt (Beans maintained their shape without being mashed.) while mashed soybean malts were made in Winger, in January of February, unmashed and mixed soybean malts were made in Summer, in July. When made fermented soybean sauce, mashed and unmashed soybean malts were used as they were and mixed soybean malt was dried and powdered for use. Fermented soybean sauce before 17th century could be classified by the features of soybean malts being used, Normal fermented soybean sauce was made from bean only soybean malts and other ingredients. Shi(시) was made from unmashed soybean malts, in which beans maintained their shape, and Gowhajang and Jeupjang were made from mixed soybean and wheat bran. Fermented soybean sauce was also made from old fermented soybean sauce, yeast. water leftover after boiling bean leaves, and soybean chaff without soybean malt. There were also side dish type soybean sauce like Kongjaban today and fish and meat sauce made from flesh ingredients. To make fermented soybean sauce in haste, the soybean sauce was heated. Beside there were how to maintain fermented soybean sauce and how to remake wrong made fermented soybean sauce.

  • Bacillus cereus is a gram-positive, rod-shaped, spore-forming bacterium that has been isolated from contaminated fermented soybean food products and from the environment. B. cereus produces diarrheal and emetic toxins and has caused many outbreaks of foodborne diseases. In this study, we investigated whether B. amyloliquefaciens RD7-7, isolated from rice doenjang (Korean fermented soybean paste), a traditional Korean fermented soybean food, shows antimicrobial activity against B. cereus and regulates its toxin gene expression. B. amyloliquefaciens RD7-7 exhibited strong antibacterial activity against B. cereus and inhibited the expression of B. cereus toxin-related genes (groEL, nheA, nheC, and entFM). We also found that addition of water extracts of soybean and buckwheat soksungjang (Korean fermented soybean paste made in a short time) fermented with B. amyloliquefaciens RD7-7 significantly reduced the growth and toxin expression of B. cereus. These results indicate that B. amyloliquefaciens RD7-7 could be used to control B. cereus growth and toxin production in the fermented soybean food industry. Our findings also provide a basis for the development of candidate biological control agents against B. cereus to improve the safety of fermented soybean food products.

  • This study was conducted to understand the quality characteristics of salt fermented anchovies with heat treatment by measuring their chemical compositions. The heat-treated and non-heat treated salt fermented anchovies contained, respectively, 63.21 and 66.51% of moisture, 2.24 and 2.12% of total nitrogen (TN), and 1,537 and 1,520 mg/100 g of amino nitrogen (AN). In addition, heat-treated and non-heat-treated salt fermented anchovies contained 127 and 134 mg/100 g of volatile basic nitrogen (VBN), respectively. Moreover, measured the microbial level of heat-treated and non-heat-treated salt fermented anchovies was $2.58{\times}10^4$ and $3.61{\times}10^2$ CFU/mL, respectively. Also, the heat-treated and non-heat-treated salt fermented anchovies 3.65 and 0.30 units of protease activities, respectively. The total free amino acid contents in heat-treated and non-heat-treated salt fermented anchovies was 4,964 and 6,638 mg/100 g, respectively. The major free amino acid were glutamic acid, leucine, lysine, alanine, valine, isoleucine. Our results provide the characteristics of salt fermented anchovies and encourage their application for the food industry and cooking.

  • 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).
