  • Meat provides high quality proteins, lipids, minerals and vitamins. The meat protein is especially high in essential amino acids that are crucial for human health, growth & development and for the formation of enzymes, hormones and antibodies. Relatively cheap and nutritionally sound vegetable proteins that are similar to animal proteins are being developed to replace the animal proteins in texture, nutrition and food characteristics. In this study a nutritionally sound meat lipid replacing food Oatrim that has been produced by converting oat starch into maltodextrin by ${\alpha}$-amylase, have been partially substituted for beef and general component analysis, texture measurement and sensory tests have been conducted. The results are 1. Water content of the non-treated (0% treated) was 67.1% and the treated (10% treated) was 77%. The treated showed better water holding capacity. 2. Protein content of the non-treated was 21.2 g/100 g; the 4% treated, 18.4 g/100 g; the 6% treated, 18.2 g/100 g; the 8% treated, 17.2 g/100g; and the 10% treated, 16.0 g/100 g. The protein content tended significant. 3. Amino acid analysis results showed that glutamic acid content was the highest in Oatrim and as its amino acid make up is exellent, it is valuable as a fine low fat protein food. 4. Sensory tests show that the increased Oatrim content increased the appearance quality but food characteristics were high only in the 4% and 6% treated groups, indicating that the replacement ratio should not exceed 10%. 5. Texture measurement analysis results show that the higher the replacement content, lower the springness, cohesiveness, hardness, chewiness and gumminess, resulting in relatively soft overall texture. However, in order to better the food characteristics, more studies must be continuously done, and so by being able to increase vegetable substitution over meat, it may be able to contribute to the prevention of adult disease.

  • Replacement of sucrose with sugar alcohols in high methoxyl pectin(HMP) jellies were studied. HMP jellies were sweetened with 100% sucrose, 75% sucrose and 25% maltitol, 50% sucrose and 50% maltitol, and 50% sucrose, 25% maltitol, 12.5% sorbitol and 12.5% mannitol. The effect of sugar alcohols in HMP jellies were investigted. There was only slight differences in sweetness intersity in HMP jellies. Color(p<0.05), texture(p<0.01) and preference(p<0.01) of 100fl sucrose jelly were significantly higher than other Jellies sweetened with sugar and sugar alcohols mixtures. Hunter's L(lightness), a(redness), b(yellowness) values of 100%, sucrose jellies and jellies substituted with maltitol up to 25% were not signignificantly different. But as the ratio and the number of sugar alcohols used for substition were increased, L, a and b values had been lowered signigicantly(p<0.01). Instru-mental characteristics of jelly texture were examined. Hardness of 100% sucrose jelly sweetened with sucrose and 3 kind of sugar alcohols were higher than others(p<0.05). As substitution ratio was higher, springiness and chewiness of HMP jellies were lowered(p<0.01). Springiness of HMP jellies indicated positive correlation with general acceptance of sensory scores at 5% significant level. Brittleness, gum-miness and cohesiveness in all types of jellies were not significantly different.

  • Salt is an essential ingredient for cheese production, and it influences various aspects of cheese, including the shelf life, enzyme activity, flavor, casein hydration, and microbial proliferation during ripening. Several consumers avoid cheese with high salt content, mainly due to health problems such as hypertension, cardiovascular disease (CVD), stroke, and heart attacks. Salt has been commonly used for several purposes in cheese production, including for obtaining the required flavor and texture, for its preservative properties, and as a taste enhancer. However, salt usage has been opposed by the public and governmental bodies, who have been advised by health authorities that salt should be reduced or avoided in cheese for healthier life. However, salt replacement or reduction in cheese manufacturing requires formulation of intensive strategies. This review provides information about several strategies and innovations for reduction and replacement of salt in cheese manufacturing without seriously affecting the quality, microbial safety, and sensory properties of cheeses.

  • This study was conducted to develope carbohydrate-based fat replacement for use in the preparation of non-(trans) fatty acid and low-caloric bread. Characteristics such as leavening height of batter, pH, titratable acidity, specific volume, sensory evaluation, shelf life and texture change of bread made using 11 types of carbohydrate-based fat replacements were measured. The 11 carbohydrate-based fat replacers (No. $1{\sim}11$) were prepared using maltodextrin as a base, and different ratios of calcium sulfate, ascorbic acid, sodium stearoyl lactylate and methyl cellulose. The pH was lowered and the total titratable acidity was increased after four hours of fermentation in the control and the samples of dough that contained the fat replacement. In addition, the leavening height of the control was 5.0cm (maximum) after two hours of fermentation and 4.6 cm after four hours of fermentation, which was similar to the heights observed when No.$9{\sim}11$ were evaluated. When the specific volume of the bread was evaluated, the 3% of fat replacement No. 10 produced the best results. When taste was evaluated, there was no significant difference between the control and the bread produced using 1% No. 10, however, there was a significant difference between the control and all samples that contained 2% or more of the fat replacement. Furthermore, the addition of a greater concentration of the fat replacer resulted in a greater moisture. However, there were no significant differences in the color of the control and any of the samples. Additionally, measurement of the firmness of the bread during four days of storage at $25^{\circ}C$ revealed that it decreased as the concentration of fat replacer increased. In addition, the sample that contained 3% of sample No. 10 showed a firmness of 18kgf after three days of storage, while the control showed a firmness of 18kg after two days, which indicates that the degradation of the bread that contained the fat replacer was delayed by one day. The bread made using fat replacers was found to have a better taste, flavor, color, texture and firmness than the control, and the best results were observed in response to the addition of 3% of replacement No. 10. The results of this study will be useful in the production of non-(trans) fatty acid, low caloric bread.

  • Experiments were conducted to assess the quality properties of steamed fish paste by addition level, along with a fish meat replacement(dried bovine plasma). The moisture, crude protein, crude fat and ash contents evidenced partially significant difference among the controls, DBP1, DBP2 and DBP3 groups(p<0.05). The pH values of the steamed samples were higher than those of the non-steamed samples, and when the content of the dried bovine plasma as meat replacement agent was increased, the pH was increased. The water holding capacity of the steamed fish past samples, along with the replacement levels were significantly higher than in the samples without the meat replacer(p<0.05). The range of cooking loss was $5.19{\sim}5.38%$. Structural weakening of the boiled samples was significantly higher than that observed in the fried sample. Hardness and chewiness were increased slightly by the addition of bovine plasma, but gel strength evidenced a pattern of decreased in DBP1, DBP2 and DBP3 groups. The result of our sensory evaluation on taste, texture, color and overall acceptance evidenced significant differences among the controls, DBP1, DBP2 and DBP3 groups, and the sensory score of color was the highest.

  • This effect of replacing pork with corn starch, chicken breast and surimi on the chemical composition, physical, texture and sensory properties of sausage were investigated during storage. Five treatments of sausage such as; T1 (10:0:0, %), T2 (10:5:0, %), T3 (10:10:5, %), T4 (10:15:10, %) and T5 (10:20:15, %) were prepared with replacement of pork with corn starch, chicken breast and surimi. The sausage made with pork meat served as control (C). The sausage in the control had higher moisture and fat contents, but lower protein content than the treatments (p<0.05). The sausages in the T2 and T5 had decreased pH values after 3 wk storage (p<0.05). The lightness value was lowest in the T3, while the yellowness values were lowest in the T5 during the storage. The TBARS (2-thiobarbituric acid reactive substance) values were lowest in the control in all storage times (p<0.05). However, the sausage in the control had higher VBN (volatile basic nitrogen) value than the treatments during the 1 wk storage (p<0.05). All treatments had significantly higher hardness, cohesiveness, springiness, gumminess and chewiness values (p<0.05) than the control. The results indicated that corn starch, chicken breast and surimi can used as a pork replacer, that it also improves the physicochemical and texture properties of pork sausages.

  • Sodium chloride (NaCl) replacement with calcium chloride (CaCl2) effect on protein solubility, proteolytic enzyme and quality characteristics of a chicken soup prepared from spent hen (SH) chicken were investigated. By means of immerse marination prior to cooking, a total of 60 skinless SH breast meat were randomly allocated into ten groups admitted to treatments with marinade solution containing sodium tripolyphosphate (STPP) and reduced percentage of NaCl with CaCl2 at 0%, 25%, 50%, 75%, and 100% at 4±2℃ for 20 h. STPP was adjusted to 0.5% for all treatments and NaCl replacement at 0% was used as control. The different methods, particularly boiling at 100℃ and retorting at 121℃, 1.5 kgf/cm2 for 60 minutes, were applied following marination. An upregulation of cathepsin-B and caspase-3 enzymes were a consequences from a higher percentage of CaCl2 within meat environment. Accordingly, modified the protein solubility in particular the myofibrillar and total protein solubility. In addition, a significant increase in water holding capacity (WHC), pH value, myofibril fragmentation index (MFI), and moisture content was obtained due to salt replacement (p<0.05). Limited effect was observed for shear force value, collagen content and cooking yield. Eventually, this study implied that although protelytic enzyme and protein solubility was upregulated by the replacement of NaCl with CaCl2 at >75%, extensive effect on texture properties was not observed. Therefore, NaCl replacement at 75% could be a promising strategy for quality improvement of SH chicken soup.
