This study investigated the quality characteristics and antioxidant activities of wet noodles as well as their cooking properties following the addition of peanut sprout extract (PSE) and powder (PSP), which are known to contain a significant level of resveratrol. Wet noodles were prepared with 0, 2.5, 5, 7.5 and 10% PSE and PSP. Quality characteristics such as increasing volume of noodle, water ratio, turbidity of cooking water and color, texture, and sensory evaluation were then assessed. Additionally, the total resveratrol content in the cooked noodles was analyzed by HPLC and DPPH free radical scavenging capacity. As the amount of PSE and PSP increased, the L value of wet and cooked noodles significantly decreased, whereas the a and b values increased (p<0.001). The L value of cooked noodles was significantly lower compared to wet noodles (p<0.001) whereas the a and b values were higher. For the cutting intensity properties of the cooked noodles, hardness was reduced with increasing amounts of PSE (p<0.001), and was significantly increased in proportion to the amount of PSP (p<0.05). Meanwhile, springiness was not significantly different in all groups. Total resveratrol content and free radical scavenging activity significantly increased in proportion to the amounts of PSE and PSP (p<0.001), especially in noodles containing 5%, 7.5% and 10% PSE and PSP. Finally, sensory evaluation of PSE noodle revealed that color, flavour, taste were significantly decreased (p<0.05). But there was no difference in overall acceptance among cooked noodles with 2.5% to 5% PSE comparison to the control. Sensory characteristics in the PSP noodle showed similar results. In conclusion, these findings suggest that peanut sprout extract and powder could be potentially used as functional food ingredients. In addition, up to 5% PSE and PSP can be substituted for wheat flour.

To develop and industrialize functional foods containing peanut sprout extract (PSE) and powder (PSP), the present study investigated the quality characteristics and antioxidant effects of breads prepared with 0, 0.5, 1, 2, 2.5, 5, 7.5, and 10% PSE and PSP. The expansion ratio of the dough, the quality characteristics such as volume, weight, specific volume, baking loss, color, texture, and sensory preference were evaluated. There were significant differences in the bread volume and specific volume among the control, PSE and PSP groups (p<0.001). Additionally, the weight and baking loss were decreased with an increasing amount of PSP (p<0.001). As the amount of PSE and PSP were increased, the L value of the crumb decreased, whereas the a and b values of the crumb significantly increased (p<0.001), suggesting that the crumb color of the bread may be significancy (p<0.001). As the amount of PSE and PSP increased, the hardness of bread significantly and rapidly increased from 5%. Meanwhile, there was no significance in springiness among the control, PSE and PSP groups. The total resveratrol content and DPPH free radical-scavenging activity of the bread significantly increased depending on the amounts of PSE and PSP (p<0.001). In the overall acceptance test, no significant differences were observed in the color, flavour, or texture, however, the taste and overall acceptance were significantly decreased between the control and the PSE group. All the sensory characteristics in the PSP group were significantly reduced compared with the control. Considering the above results, it can be expected that the suitable amount of PSE and PSP substituted for wheat flour will be from 1.0 to 2.5%. Furthermore, follow-up studies are being carried out continuously.

Objective: The purpose of this study was to investigate whether addition of konjac gel with three different vegetable powders can increase quality of low-fat frankfurter-type sausage. Methods: Low-fat frankfurter-type sausages were manufactured with formulations containing konjac gel and three vegetable powders (aloe vera, cactus pear, or wheat sprout) as pork fat replacers. The formulations of frankfurters were as follows: NF (normal-fat; 20% pork fat), LF (low-fat; 10% pork fat), KG (low-fat; 10% pork fat+10% konjac gel), and konjac gel with three vegetable powders (KV), such as KV-AV (10% pork fat+10% konjac gel with aloe vera), KV-CP (10% pork fat+10% konjac gel with cactus pear), and KV-WS (10% pork fat+10% konjac gel with wheat sprout). Proximate analysis, pH value, color evaluation, cooking loss, water-holding capacity, emulsion stability, apparent viscosity, texture profile analysis, and sensory evaluation were determined. Results: The konjac gel containing groups showed lower fat content (p<0.05) and higher moisture content than NF group (p<0.05). The pH value of frankfurters was decreased in three KV groups (p<0.05). The three KV groups had increased dark color (p<0.05) compared with KG, and KV-CP had the highest redness (p<0.05). The water-holding capacity and emulsion stability were higher in the three KV groups than KG and LF (p<0.05). Cooking loss was generally decreased in the three KV groups, compared with KG (p<0.05). The apparent viscosity of KV groups was similar with NF group and overall texture properties were improved in KV-CP. In the sensory evaluation, the highest overall acceptability was found in KV-CP groups (p<0.05). Conclusion: The four fat replacers improved physicochemical properties of low-fat frankfurters. Particularly, konjac gel with cactus pear powder seems more acceptable as a pork fat replacer.

The objective of this study was to investigate the effects of different concentrations of WSP (wheat sprout powder) and ISP (isolated soy protein) on the quality of breakfast sausage. Treatments were formulated as follows: Control, T1 (2.0% ISP), T2 (1.5% ISP + 0.5% WSP), T3 (1.0% ISP + 1.0% WSP), T4 (0.5% ISP + 1.5% WSP) and T5 (2.0% WSP). The treatments were analyzed for color, pH, cooking loss, emulsion stability, protein solubility, viscosity, texture properties and sensory evaluation. Lightness and redness were reduced and yellowness was increased as increased level of WSP, due to the dark green color of WSP (p<0.05). The pH values of all samples were affected by WSP which has lower pH (p<0.05). The emulsion stability and cooking loss of treatments were improved with increasing level of WSP (p<0.05). The protein solubility, viscosity and overall texture properties of the sausage indicated significant differences in relation to the level of WSP and ISP (p<0.05). The sensory evaluation indicated that the greatest flavor and overall acceptability in sausage was achieved at WSP 1% combination with ISP 1% (T3) (p<0.05). Therefore, these results indicate that breakfast sausage containing 1% WSP and 1% ISP is the optimal formulation, taking into consideration the overall physico-chemical properties and sensory evaluation.
