  • We investigated the physical properties and color values of surimi mixtures with added natural red pigments from laver Pyropia yezoensis. After adding the natural red pigment from seaweed extract to surimi, the hardness, gumminess, and chewiness of the surimi decreased compared to the negative controls. The L* color value was lower for the surimi mixture than the negative controls, but the a* and b* color values were higher. After cold storage for 7 days, the unheated surimi mixture showed increased firmness, but decreased adhesiveness. Moreover, the gumminess and chewiness of the surimi mixture stored after heating were increased compared to the pre-storage values. These results indicate that seaweed extract pigments may be used as additives for surimi, to increase the color preference, with little effect on the physical properties.

  • A strain antagonistic to Fusarium solani, CHO104, was selected from approximately 100 microorganisms isolated from soil. Strain CHO104 was identified as Bacillus amyloliquefaciens and found to be Gram-positive based on the Biolog system and 16S rRNA methods. A culture broth of B. amyloliquefaciens CHO104 also exhibited antimicrobial activity against various microorganisms. As such, the EtOAc extract of the culture broth was isolated by various column chromatographic procedures and HPLC. The antimicrobial and antifungal substance was then characterized as macrolactin A $(C_{24}H_{34}O_5)$ using high-resolution EI-MS and NMR analyses, and found to be very effective in inhibiting the growth of Staphylococcus aureus, E. coli, and Botrytis cinerea, even when using a concentration of one-twentieth of the benzoic acid as the control compound.
