The market size of home meal replacement (HMR) products has been gradually growing worldwide, even in Korea. In Korean HMR products, meat is the most important food ingredient compared with rice and vegetables. Therefore, this study aimed to evaluate changes in physiochemical and sensory aspects of beef under different preparation processes. For preparing four treatments, beef eye of round (ER) added with salt and sugar (treatment 1) and that without salt and sugar (treatment 2) were mixed with rice and frozen at $-50^{\circ}C$. Beef ER without salt and sugar was also topped onto the rice and frozen (treatment 3), and that was topped onto the rice and precooled before freezing (treatment 4). Physiochemical analyses included cooking and drip losses, shear force, color, salt soluble protein, and sensory attributes were tested. The results showed significantly higher drip loss and total loss in beef ER samples 1 and 2, which were mixed with rice, compared to beef ER samples 3 and 4, which were not mixed with rice. A significantly higher discoloration was also observed in beef ER samples 1 and 2, compared to that in samples 3 and 4. In the partial least squares regression (PLSR) analysis, beef ER sample 4 (precooled before freezing) was highly related to sensory attributes, such as flavor, overall acceptability, and juiciness, and far from non-preferred shear force. As a result, beef ER in HMR sample 4 was the most preferable to the sensory panel, and it had the most desirable physicochemical analysis outcomes.

The effects of salt and bicarbonate solution on overall meat quality in beef biceps femoris muscle were investigated with the application of chilling and freezing conditions. Muscles were injected to a target of 120% of original meat weight with a solution containing 1.2 M sodium chloride, 0.25 M sodium bicarbonate and 0.1% ascorbic acid (pH 7.2). Half of the meat samples, considered as chill treatment and chill control, were stored at $4^{\circ}C$ up to five days; while the other half, frozen treatment and frozen control, were kept in a freezer at $-20^{\circ}C$ for seven days. Compared with untreated control, treated meats had higher water holding capacity (p<0.05), lower drip loss (p<0.05) and lower shear force (p<0.07) with higher overall acceptability (p<0.05) in sensory evaluation. Morphological observations demonstrated smooth and gummy meat surface due to the solubilization of myofibrillar proteins and the distortion of connective tissue in treated raw meats; and in the case of cooked meat, treatment caused the fragmentation of myofibrils, which might be responsible for a lower shear value in salt-bicarbonate treated beef biceps femoris muscle.

This study was conducted to develop low-salinity Kimchi with acetic acid, starters and fruits added for health and taste. The quality characteristics of the developed Kimchi by storage period and salt concentrations were investigated herein. The effects of salinity and fermentation temperature ($0^{\circ}C$, $5^{\circ}C$) on the quality characteristics of low-salinity Kimchi were investigated through physicochemical and microbiological analysis. The sensory characteristics are shown in the results below. The pH and acidity were quickly changed by higher temperature over longer storage periods, with gradual decrease in the pH accompanied with an increase in acidity. The microbiological analysis revealed increase in the total cell number regardless of the concentration and strain added during the storage period. Finally, test of the overall acceptability with regard to sensory characteristics according to the different strain sets in low-salinity Kimchi showed the average score for smell, salty taste and overall acceptability were highest in the hetero-fermentation strain group.

Seolleongtang, a traditional broth in Korea, is expected to become a hot global item for its unique flavor and healthiness. In this study, the correlations between sensory attributes and physicochemical characteristics were studied for the popular seolleongtang stock products through descriptive analysis, sensory evaluation and analysis of salt, soluble solid, protein, viscosity and color for the quality control. Our results indicate that color, concentration, viscosity, and freshness are important attributes in evaluating the quality of seolleongtang stock. There were significant differences between preference and sensory attributes among the stock products. Significant correlations were found between flavor and texture and overall acceptability, as well as beany odor and aroma. Preference and physicochemical aspects also correlated, and indicate that a range of salt, solubility, and viscosity are applicable as quality control factors in seollengtang stock.

Characteristics of six commercial samjangs were analyzed such as proximate composition, free amino acids, organic acids and free sugars. Also color, taste and odor were evaluated by 36 panelists. They were composed of moisture content 41.4-48.4%, crude protein 9.2-10.4%, crude fat 2.2-3.4%, pH 5.3-5.7, amino nitrogen 194.0%-375.6 mg% and sodium chloride 7.7-9.1%. Total free amino acids of samjangs were 975.89-2304.98 mg%. Glutamic acid was the highest amino acid among free amino acids as 231.7-788.01 mg%. Proline, arginine, alanine and lysine were higher than other free amino acids while histidine, cystine and methionine were lower than other. Eleven free amino acids including glutamic acid were the highest in samjang (B) which contained more doenjang than any other makers did. Total organic acids were 401.01-640.27 mg%. 69.65-269.07 mg% of succinic acid was the highest among organic acids. Lactic acid was the highest in samjang (F) which was home made. Total free sugars was the highest in samjang (A) which contained more wheat flour than any other makers did it. Glucose was 9.30-23.99% and fructose was nd-2.69%. The result of proximate composition showed a different pattern comparing with that sensory evaluation. Samjang (A) which contained less salt showed the highest overall acceptability while samjang (F) which contained more dark color, more salt was the lowest one among the samples.

Fermentation temperature and salt concentration of Dongchimi were studied for the development of low salt Dongchimi juice. The juice was prepared by soaking the radish in brine solution of 0.3∼3.0% and fermented at the temperature range of 10∼30$^{\circ}C$. The fermentation proceeded faster at higher temperature. However, the salt concentration effect was dependent on the temperature. Fermentation in 3.0% NaCl solution resulted the fastest reach to pH 3.8 followed by 0.5% NaCl at 10 and 20$^{\circ}C$, while higher NaCl concentration caused a decrease in the fermentation rate at 30$^{\circ}C$. Comparison of flavor of the juice of pH 3.9 showed that fresh sourness was high in the juice prepared at 20$^{\circ}C$ and in 0.5% NaCl. The preference test also showed the juice of pH 3.8∼4.0 fermented in 0.5% NaCl at 20$^{\circ}C$ to be the most preferable one. The salt concentration lower than 0.5% at 20$^{\circ}C$ resulted in faster fermentation and high values in turbidity. However 0.5% NaCl was scored high in flavor acceptability.

Recrystallization characteristics of salt after removing bittern and impurities from solar salt (SD) were investigated. To remove the bittern, the SD was treated at 30, 40 and $50^{\circ}C$ under 95% humidity. 86% of the bittern was removed when the SD was kept at $30^{\circ}C$ for three weeks. Total amount of impurity in SD was 6.94% (w/w) with organic impurity (5.58%) and inorganic impurity (1.36%). Most organic impurities (89%) were soluble. When the SD was roasted at $350^{\circ}C$ for 40 minutes, 90.14% of the soluble organic impurities were removed; however, the removable organic impurity was reduced, when the SD roasted for 50 minutes at $350^{\circ}C$. L* value decreased while a* and b* values increased when the SD was roasted until 40 minutes at $350^{\circ}C$. In contrast, L* value increased while a*, b* values decreased with SD roasted over 50 minutes at $350^{\circ}C$. The size of recrystallized pure salt was positively correlated to temperature and depth of salt solution, while the crystallization time was negatively correlated to temperature and salinity. Yield of recrystallized salt was negatively correlated to temperature. Overall acceptability tended to increase at low crystallization temperature and high salinity.
