The quality characteristics of cookies with 0%, 2%, 4%, 6%, and 8% acaiberry (Euterpe oleracea Mart.) powder added were analyzed through chemical and sensory evaluations. The moisture contents of the cookies were insignificant (p<0.05) as the acaiberry powder levels (0%, 2%, 4%, 6%, and 8%) increased. The pH values of the cookies were significantly reduced in all the acaiberry powder groups compared to the controls. According to the Hunter color of the cookies, tbe L-value (lightness) and the b-value (yellowness) significantly decreased (p<0.05), whereas the a-value (redness) increased when the acaiberry powder was added at different levels (0%, 2%, 4%, 6%, and 8%). The spread factor decreased significantly (p<0.05) with the acaiberry powder addition levels (0%, 2%, 4%, 6%, and 8%). The hardness of the cookies significantly decreased (p<0.05) according to the increase in the acaiberry powder level (0%, 2%, 4%, 6%, and 8%). The sensory evaluation of the cookies showed that those with 6% acaiberry powder added had the greatest of the color, taste, flavor, texture, and overall acceptability. These results showed that up to 6% acaiberry powder can be added to cookies.

The quality characteristics of Yanggaeng with 0%, 2%, 4%, 6%, and 8% acaiberry (Euterpe oleracea Mart.) powder added were analyzed for physicochemical, antioxidant effects, and sensory preferences. The moisture contents of the Yanggaeng added with acaiberry powder were significantly(p<0.001) increased as the acaiberry powder levels (0%, 2%, 4%, 6%, and 8%) increased. The pH and $^{\circ}brix$ values of Yanggaeng added with acaiberry powder were significantly reduced as the acaiberry powder levels(0%, 2%, 4%, 6%, and 8%) increased (p<0.001). According to the hunter color of Yanggaeng added with acaiberry powder, the L-value(lightness) and the b-value(yellowness) significantly decreased(p<0.001), whereas the a-value(redness) increased as the acaiberry powder levels increased(p<0.001). For the textural characteristics, the addition of acaiberry powder decreased the hardness(p<0.001), gumminess(p<0.001), cohesiveness(p<0.05), and chewiness(p< 0.01), whereas springiness not significantly changed. The total polyphenol contents and DPPH radical scavenging activities were significantly increased aciberry powder(p<0.01, p<0.001). In sensory evaluation, Yanggaeng addition with 4% acaiberry powder had excellent scores in taste and overall sensory preference. These results suggest that acaiberry powder may be a useful ingredient in Yanggaeng for the improvement of sensory preference and antioxidant potential. Considering both the functional and sensory preference aspects of the acaiberry Yanggaeng, the 4% acaiberry powder dosage level can be considered ideal.

This study was to examine the quality characteristics of sulgidduk added with acaiberry (Euterpe oleracea Mart.) powder. Rice powder was added to acaiberry (Euterpe oleracea Mart.) powder at ratios of 0, 3, 6, 9, 12 and 15%. The moisture content of sulgidduk added with acaiberry (Euterpe oleracea Mart.) powder ranged from 36.25% to 39.21%. According to the ratios of acaiberry (Euterpe oleracea Mart.) powder decreased the pH value. The addition of acaiberry (Euterpe oleracea Mart.) powder tended to decrease the L-value and the b-value of the color, but to increase the a-value of the color. In texture analysis, the hardness, gumminess and chewiness increased with increasing acaiberry (Euterpe oleracea Mart.) powder contents, but cohesiveness decreased. According to sensory evaluation, sulgidduk added with acaiberry (Euterpe oleracea Mart.) powder 9% had the highest values at color, flavor, texture and overall acceptability. These results suggested that sulgidduk added with acaiberry (Euterpe oleracea Mart.) powder 9% were considered the best.

In this study Muffins adding each 0, 1, 3, 5 7% of Acai Berry powder, which has very high anti-oxidant constituent, have been made, and its quality characteristics have been surveyed. From the volume and specific volume measurement, it has been decreased for MA1, 1% of Acai Berry powder added muffin, but the tendency thereafter has shown increasing (p<0.001). From texture characteristics gumminess and chewiness of MA0, reference group, was the highest by 885.86 g/ cm and 6645.71 g, and has shown decreasing tendency as per the adding rate of Acai Berry powder increased (0.001). The electronics scavenging activity of MA7, 7% added muffin, was the highest by 68.91%, and the ascending order was MA1 < Reference Group < MA3 < MA5 < MA7. From the preference test of Acai Berry powder added muffin, MA3, 3% added muffin, was the most preferable one from color, taste as well as total preference. As the added volume of Acai Berry powder is 5% or more, the typical taste and flavor of Acai Berry gives influence to the taste and flavor of muffin, so the preference level has been decreased. Thus the added volume of Acai Berry powder 5% or more is not recommendable.
