In this study, the quality characteristics of cookies with the addition of Spergularia marina Griseb powder (SMGP) were investigated and analyzed by through chemical and sensory evaluation. Cookies were prepared with different levels of SMGP (0, 1, 3, and 9%). Their moisture and crude protein contents decreased after the addition of SMGP, as did their spread factor (p<0.05). Their Hunter's color L and a values significantly decreased with the increase in SMGP level, whereas their b value increased (p<0.05). In the texture analysis, the hardness of the cookies increased according to the increase in concentration of SMGP and showed a significantly high level in the cookies with the addition of 9% SMGP (p<0.05). In the sensory evaluation, the cookies with the addition of 3% and 9% of SMGP had the highest scores in flavor, taste, and texture (p<0.05). The cookies with 3% SMGP addition had the best score in total acceptability. This study suggests that SMGP is a good ingredient for improving the acceptability and functionality of cookies.
This study was performed to investigate the effects of lemon balm (Melissa officinalis L.) on various quality and antioxidant activity of hamburger patties. Lemon balm extract (LBE) showed the highest amount of total polyphenol (801.00 mg TAE/g DW) and flavonoids (65.05 mg RA/g DW). The IC50 value of DPPH hydroxyl scavenging of LBE was 132 μg/mL. The hamburger patties were prepared by 0% (N), 0.1% (L1), 0.5% (L2), and 1.0% (L3) of the lemon balm powder. The addition of lemon balm powder increased the chewiness value, but did not affect the hardness, cohesiveness, and springiness values. Lemon balm powder had positive effects on sensory evaluation of patties. The pH of all patties decreased with longer storage period. 2-Thiobarbituric acid value, volatile basic nitrogen content, and the total microbial counts of hamburger patties in the L3 group were lower, compared to those of the normal (N group). In conclusion, the L3 group had significantly delayed lipid peroxidation compared to other treatment groups. However, the addition of lemon balm powder into patties showed no significantly influence on proximate composition, calorie contents, water holding capacity and cooking loss of patties. Therefore, lemon balm might be a useful natural antioxidant additive in meat products.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
