This study was conducted to investigate the physical, textural and sensory properties of Seolgiddeok prepared with different amount of radish leaf powder, and stored for 3 days. The moisture content decreased gradually during storage and the decrease was less in the groups with radish leaf powder than in the control. The color L value decreased significantly as the amount of radish leaf powder increased, while the redness (a) and yellowness (b) both increased. Measurements with a texture analyzer, showed that the hardness, chewiness, gumminess and adhesiveness of Seolgiddeok tended to decrease in proportion to the amount of radish leaf powder in the formula. The gelatinization properties of Seolgiddeok were investigated by amylograph. Breakdown and setback in Seolgiddeok were low following the addition of radish leaf powder. In the sensory evaluation, Seolgiddeok with radish leaf powder was superior in flavor, chewiness, and softness than the control. Seolgiddeok with 3% radish leaf powder had the highest overall acceptability score. Therefore, we concluded that the addition of radish leaf powder to Seolgiddeok improves the sensory characteristics and delays retrogradation.

The aim of this study was to optimize the best recipe to make acorn bread containing milk as a functional food. The color value, textural, and sensory properties of the acorn bread added with 10~40% ratio of milk were measured to develop the best recipe. As a result, the L-value of color increased with the amount of milk added, but the a- and b-values decreased. As the textural measurement, the hardness increased with increasing milk added. Cohesiveness and springiness decreased, but the gumminess and brittleness increased with the addition of 20% milk, and decreased with further addition. The sensory evaluation revealed color, taste, and overall acceptances to have high scores at 20% addition of milk. Softness and chewiness were good at 10% addition. During the storage periods at room temperature, the L- and b-values increased with the addition of milk, whereas a-value decreased. In freezer storage, the L-value increased with milk content added, but the a- and b-values decreased during the storage periods. The textural properties increased during the storage at room temperature. The addition of milk decreased the cohesiveness and springiness, but the gumminess and brittleness increased significantly after one day storage. In freezer storage, all textural properties increased significantly during the storage periods, but the hardness decreased after two days storage. With the increasing amount of milk added increased the cohesiveness, springiness, and the gumminess except for four days, but decreased hardness and brittleness after two days storage. Therefore the addition of milk in acorn bread improved the textural properties significantly.

The textural and rheological properties of cheese are major attributes for the characterization of cheese types, ripening, and consumer preferences. The use of small amplitude oscillatory rheological testing has made it possible for cheese researchers to assess the major properties of cheese, such as melting behavior and storage modulus, without irreversible deformation. In addition, large deformation testing such as textural profile analysis can assess properties such as hardness of cheese. While the sensory properties of cheese are valued by consumers, objective and reliable measurements are paramount for researchers. Ongoing development and refinement of scientific measurement methods of cheese are vital.

To find the possibility in utilizing the fish meat processing by-products, protein nutritional quality and textural properties of crucian carp extraction residue (CCER, feeze dired) incorporated into cookies were investigated. Moisture, ash and protein contents in cookies were increased with the higher residue treatments, but lipid contents were similar within all levels (3%, 9% and 15%). Major constitutional amino acids were revealed as glutamic acid, proline, leucine and arginine, and the sum of those amino acids was about 50% of total amino acid contents. Cookies with residue (CCER) had higher (80.74~84.50%) in vitro protein digestibility than standard cookies (83.32%), while slightly lower trypsin indigestible substrate (TIS) contents were showed in CCER containing cookies than control. CCER treatments resulted the decreased protein nutritional quality in C-PER (computed protein efficiency ratio) value from 2.41 (standard) to 1.15 (cinnamon flavored. 9% CCER), and those C-PER of all cookies were lower than ANRC casein (2.50). Lipophilic browning was developed steadily till 60 days storage and a significant (p<0.05) changes of browning ws not noteed between 60 days and 90 days storage. Color of cookies, expressed as L, a and b value, was significantly (p<0.05) lightened with the increased CCER. Similar trends by treatments were noted for hardness. Cookies containing 9% CCER were similar to control regarding textual and sensory properties.

In order to increase the use of waxy barley, cakes were made and the textural and sensory properties were investigated. The moisture content of cakes made out of waxy barley grain and flour were 51.0 and 52.1%, respectively. L values in color of the waxy barley cakes tended to decrease during 3 day storage at 15$^{\circ}C$. Textural analysis showed that there were no differences among two waxy barley and waxy rice cakes in hardness at fresh state. But after 3 day storage at 15$^{\circ}C$, the hardness of the waxy barley cake was lower than that of waxy rice cake. These results implied that the degree of retrogradation of waxy barley cake might be low due to its high dietary fiber content. The hardness and adhesiveness of the waxy barley cake thawed after 15 day freezing were not significantly different from those of the fresh cake. In sensory evaluation, the overall preference of waxy barley cake was lower than that of waxy rice, but the sensory score of the cake made of waxy baley flour was above 4 point in the 5 point scale, showing a patency of waxy barley for the cakes.

Objective: This study was conducted to evaluate the effect of red glasswort (RG) (Salicornia herbacea L.) curing on the physicochemical, textural and sensory properties of cooked pork loin ham (M. longissimus thoracis et lumborum). Methods: All treatments were cured with different salt and RG powder levels. RG0 treatment was prepared with only 4% NaCl (w/w) as a control, and RG25, 3% NaCl:1% RG (w/w); RG50, 2% NaCl:2% RG (w/w); RG75, 1% NaCl:3% RG (w/w); RG100, 0% NaCl:4% RG (w/w) treatments were prepared sequentially. All samples were individually vacuum packaged in polyethylene bags and stored for 7 d at 3℃±1℃. Results: The results showed that as the rate of RG substitution increased, pH value, redness, myofibrillar protein solubility, and myofibrillar fragmentation index increased (p<0.05), but salt concentration and shear force decreased (p<0.05). However, there were no significant differences in cooking loss and moisture content. In terms of sensory evaluation, RG100 exhibited higher scores in tenderness and juiciness than RG0 (p<0.05). Conclusion: The partial substitution of NaCl by RG could improve the physicochemical properties, textural and sensory characteristics of cooked pork loin. Therefore, it is suggested that RG as a natural salt replacer could be an effective ingredient for developing low-sodium cured hams.

This study was carried out to investigate the textural and sensory properties of pork jerky with differently added sources of tenderizer or humectant at final concentrations of 2 or 5% (v/w). Pork jerky treated with 5% glycerol, kiwi, or pineapple had lower moisture content and water activity than that of control pork jerky (p<0.05). The addition of tenderizer or humectant resulted in a lower shear force than that of control (p<0.05). The addition of 2 or 5% glycerol resulted in higher equilibrium moisture content (EMC) than other treatments, and addition of tenderizer or humectant produced a higher EMC than that of control (p<0.05). Furthermore, addition of pineapple and kiwi to the samples affected the structures of the myosin heavy chain and the actin filaments of myofibrillar protein, respectively. Trained panel sensory evaluations indicated that pineapple enhanced the flavor score, whereas tenderness score was improved by the addition of tenderizer or humectant (p<0.05).

While attempting to develop low salt, low fat and high fibre chicken nuggets, the effect of partial (40%) common salt substitution and incorporation of chickpea hull flour (CHF) at three different levels viz., 5, 7.5 and 10% (Treatments) in pre-standardized low fat chicken nuggets (Control) were observed. Common salt replacement with salt substitute blend led to a significant decrease in pH, emulsion stability, moisture, ash, hardness, cohesiveness, gumminess and chewiness values while incorporation of CHF in low salt, low fat products resulted in decreased emulsion stability, cooking yield, moisture, protein, ash, color values, however dietary fibre and textural properties were increased (p<0.01). Lipid profile revealed a decrease in total cholesterol and glycolipid contents with the incorporation of CHF (p<0.01). All the sensory attributes except appearance and flavor, remained unaffected with salt replacement, while addition of CHF resulted in lower sensory scores (p<0.01). Among low salt, low fat chicken nuggets with CHF, incorporation CHF at 5% level was found optimum having sensory ratings close to very good. Thus most acceptable low salt, low fat and high fibre chicken nuggets could be developed by a salt replacement blend and addition of 5% CHF.
