The purpose of this study was to examine the effect of noni (Morinda citrifolia) powder on the physicochemical properties and antioxidant activities of ground pork meat. Four samples of ground pork meat were prepared as follow: CON without noni powder, NP0.5 with 0.5% noni powder, NP1.0 with 1.0% noni powder, and NP1.5 with 1.5% noni powder. The moisture content of CON was the highest (p<0.05). The ash, fiber, fat retention, hardness, cohesiveness, gumminess, chewiness, lightness, and yellowness increased with the addition of the noni powder (p<0.05). The protein, fat, water holding capacity, cooking yield, moisture retention, springiness,and redness of the cooked meat were not significantly different among the samples. The pH of CON was the highest among the samples (p<0.05). The TBARS of CON, NP0.5, NP1.0, and NP1.5 were 0.48, 0.41, 0.36 and 0.34 mg/kg, respectively, and the NP1.5 was the lowest (p<0.05). The DPPH radical scavenging activity of CON, NP0.5, NP1.0, and NP1.5 were 10.4%, 20.8%, 34.6% and 45.3%, respectively, and the NP1.5 was the highest (p<0.05). Consequently, these results support the possible use of noni powder for meat product industry, as addition of noni powder enhances the antioxidant activities of ground pork meat.

The purpose of this paper was to study cookies that could be sweetened by consumers through the addition of Morinda citrifolia powder, and also to examine the quality characteristics of such cookies in order to expand the uses of Morinda citrifolia. The addition of Morinda citrifolia powder did not have an observable affect on cookie density, although it did decrease pH levels. A central finding was the lack of significant differences in moisture content of cookies made with Morinda citrifolia powder at the significance level of 5%. Significant differences were found in the diameter, which represents spreadability, in the group of cookies made with Morinda citrifolia powder. The L value decreased considerably with the addition of Morinda citrifolia powder. The control also recorded the highest hardness points and had significant differences from the groups added with 3% and 6% Morinda citrifolia powder. The sensory evaluation results showed no significant differences in the taste, flavor, texture, and overall preference between the group of 6% Morinda citrifolia powder and the control except for color, which suggests that cookies made with 6% Morinda citrifolia powder seem to be ideal.
