  • Kimchi is a traditional fermented food of Korea and made by salting and fermenting vegetables. A negative impression on kimchi as a great source of sodium intake has grown in Korea since 1980 as people argue that sodium is a major cause of high blood pressure and metabolic syndrome. While people are more interested in healthy living in Korea, the negative impression is stronger now. This study analyzes the sensitive and negative reaction to sodium intake from kimchi, and suggests an alternative in the viewpoint that the sensitive reaction is one of food faddism which is a very popular topic currently in Korea.

  • Alternative protein sources with greater nutritional value and a lower environmental footprint have recently attracted interest in the production of meat substitutes. However, it is required that these alternatives mimic the texture and structure of meat. This study investigated varying ratios of textured vegetable proteins (TVP) to Tenebrio molitor larvae (brown mealworm; TM) with the addition of transglutaminase (TG) to determine the quality characteristics of these emulsions. The results demonstrated low protein solubility of the emulsions as TVP content increased. Furthermore, when the proportion of TM was high, the TG-treated emulsion had a low pH. Additionally, when there was a high TM ratio to TVP in the TG treatment, the emulsions demonstrated better thermal stability and water holding capacity. Regarding the rheological properties of the emulsion, both the frequency-dependent storage modulus (G') and loss modulus (G'') increased as the proportion of TVP in the emulsion increased with and without the addition of TG. Differential scanning calorimetry analyses demonstrated two protein denaturation peaks in all treatments, with high peak temperatures for both treatments with a high proportion of TM. The hardness and chewiness of the emulsion were highest in the treatment (T6 and T8) with TG, and the gumminess of the emulsion was greatest when TM only or when equal ratios of TVP and TM were treated with TG, respectively. In conclusion, the addition of TM to TVP with TG improves the overall texture of the protein mixture, making it a suitable meat alternative.

  • Among 12 lactic acid bacteria examined for their abilities to activate the complement system by hemolytic complement assay $(TCH_{50})$, Lactobacillus plantarum previously isolated from Kimchi showed high anti-complementary activity. The anti-complementary activity of the cell wall fraction of L. plantarum was more potent than that of the cytosol fraction, and both activities showed dose dependency. These high activities of the cytosol and the cell wall fractions were relatively resistant to the digestion with pronase, but sharply decreased after the treatment of $NaIO_4$. These results suggested that the complement activation by the cytosol and the cell wall fractions was mainly due to their polysaccharides. By the cross-immunoelectrophoresis using anti-human C3, the C3 activation products from both fractions were identified in $Ca^{++}$-free condition. Anti-complementary activity $(ITCH_{50})$ of the cell wall fraction was retained under the same condition, whereas that of the cytosol fraction was reduced considerably. From these results, it was inferred that the mode of complement activation by the cell wall fraction was mainly via alternative pathway, and that of the cytosol fraction was via both alternative and classical pathways.

  • This study was conducted with a view toward enhancing the industrial utilization of a male sailfin sandfish Arctoscopus japonicus based on its application in the preparation of Sik-hae, a Korean traditional fermented fishery product prepared using hard-boiled rice and enzymatic malt sprouts. As an alternative to rice and malt sprouts, we evaluated the utility of rice Koji for Sik-hae fermentation by investigating the physicochemical changes that occur during fermentation. The sailfin sand fish Sik-hae fermented with 10% or 20% rice Koji was found to show similar fermentation characteristics to the control fermentation with 20% hard-boiled rice and 4% malt sprouts, with respect to acid production, texture profile, and the softening of bones during the entire fermentation period. In particular, compared with the control, the addition of 10% rice Koji reduced the dehydration of Sik-hae and increased the content of free amino acids, which contributed to preventing a marked reduction in pH during fermentation. Accordingly, 10% rice Koji is proposed as a viable alternative enzymatic agent for the preparation of Sik-hae, which can contribute enhancing the desired properties of this traditional food product.

  • Food sovereignty is the right of peoples to healthy and culturally appropriate food produced through ecologically sound and sustainable methods, and their right to define their own food and agriculture systems. An increase in the price of food that occurs as a result of increased demand from human consumption and use as an alternative energy resource. Furthermore, agflation, a combination of the words "agriculture" and "inflation", will also affect non-vegetative foods as the price increases for grain will make livestock feed more expensive as well. Food sovereignty implies new social relations free of oppression and inequality between men and women, peoples, racial groups, social classes and generations.

  • This study was performed to develop and evaluate beverage prepared with optimally roasted seoritae to maximize the isoflavone content and antioxidant activities of the beverage. Isoflavone content was maximized at the roasting temperature of $110^{\circ}C$ for 20 min. Both DPPH radical scavenging activity and ABTS radical scavenging activity along with total polyphenol content were highest when seoritae was roasted at $110^{\circ}C$ for 20 min. Western blotting was used to determine the level of nuclear factor of activated T-cells 1(NFATc1) involved in controlling osteoclast differentiation. The results showed that NFATc1 had a concentration-dependent inhibitory effect when the RoS110 (roasted seoritae at $110^{\circ}C$ for 20 min) samples were processed at varying concentrations (10, 50, and $100{\mu}g/mL$). Tea samples were prepared from optimally roasted seoritae by varying brewing times (5~90 min) at $65^{\circ}C$, and tea brewed for 60 min had the highest preference with $65^{\circ}C$ as the preferred temperature for drinking.

  • To identify the effect of sodium-alternative curing salts on the quality properties of salami through the ripening process, four salami treatments were prepared with different curing salts, T1 (-control, NaCl 1.9%), T2 (+control, NaCl 1.9%+NaNO2 0.01%), T3 (KCl 1.9%+NaNO2 0.01%), and T4 (MgCl2 1.9%+NaNO2 0.01%), under 40 days ripening conditions. Sodium-alternative salts (T3 or T4) showed characteristically different quality traits compared with T2. Especially, T3 had lower pH, water activity, volatile basic nitrogen, and lipid oxidation after 20 days of ripening period, compare with T2 or T4 (p<0.05). Sodium nitrite had critical impact on increased a* values, and T3 showed higher a* values compared with T2 or T4 (p<0.05). Sodium nitrite reduced initial growth of coliforms but sodium-alternative salts did not affect microbial growth patterns. T2-T4 containing sodium nitrite had higher content of umami nucleotide flavor compounds compared with T1, regardless of the chlorine salt species. The combined use of sodium-alternative curing salts and minimal sodium nitrite was found to be an applicable strategy on development of low sodium salami without a trade-off of the product quality.

  • In this study, we investigated the optimal conditions for 3D structure printing of alternative fats that have the textural properties of lard using beeswax (BW)-based oleogel by a statistical analysis. Products printed with over 15% BW oleogel at 50% and 75% infill level (IL) showed high printing accuracy with the lowest dimensional printing deviation for the designed model. The hardness, cohesion, and adhesion of printed samples were influenced by BW concentration and infill level. For multi-response optimization, fixed target values (hardness, adhesiveness, and cohesiveness) were applied with lard printed at 75% IL. The preparation parameters obtained as a result of multiple reaction prediction were 58.9% IL and 16.0% BW, and printing with this oleogel achieved fixed target values similar to those of lard. In conclusion, our study shows that 3D printing based on the BW oleogel system produces complex internal structures that allow adjustment of the textural properties of the printed samples, and BW oleogels could potentially serve as an excellent replacement for fat.
