Tomato sauce is widely known as a health food, In this study perilla leaf was added to a tomato sauce and the resulting functional improvements were assessed. The moisture of the tomato sauce WITH 2% added perilla leaf was 89.52%, the highest observed likewise, sample pH also significantly increased with 2% perilla leaf, to the highest pH of 4.71, (p>0.001). Lightness L value of the control group was the highest at 40.70, and the redness a value and yellowness b value were highest in, the control group, at 15.77, and 17.70, respectively. The highest salinity was foung with 2% perilla leaf, 0.96, and the sugar content with 2% perilla leaf, was 9.57. The reducing sugar was highest in the control with 63.08. The change in the total bacterial counts was measured during 9 days of storage at $4^{\circ}C$, When perilla leaf was added to, the tomato sauce, no microorganisms were detected until 0~1 days of storage. After five days of storage, microorganisms were detected in the group with 2% perilla leaf. The control group ($1.8{\times}10^5$ CFU/ml) had the highest levels of microorganisms. As the amount of perilla leaf, the total viable count of microorganisms detected was less. In the acceptability test results, the color 6.9 of the 1.5% treatment group, received the highest evaluation. Flavor and taste of the 2% perilla leaf treatment group were highly appreciated at 6.1 and 6.6, respectively. The ranking of overall acceptability was 1.5%>1%>0.5%>10%>2% of perilla leaf; 2% perilla leaf was the most underrated. Based on these results, up to 1.5% perilla leaf could be added to tomato sauce and the commercial potential could be very high.

This study was conducted to evaluate the effect of various types of functional brown rice milk porridge, which has been popular as a fast yet nutritional food, to promote rice consumption and to examine the best ratio and recipe. Each sample contained 10, 20, 30, and 40% brown rice compared to non-glutinous rice and sweet rice and were applied to mechanical and sensory tests. The moisture content of both non-glutinous rice and sweet rice porridges increased with increasing brown rice content. The viscosity of non-glutinous rice milk porridge decreased as with increasing brown rice content, whereas the viscosity of sweet rice milk porridge increased with increasing brown rice content. The pH was highest for BRT0 at 6.74 and lowest for BGT0, which is sweet rice porridge with brown rice, at 6.27. The sweetness decreased significantly for both sweet rice and non-glutinous rice porridges with the increase in brown rice content. The brightness of weet rice and non-glutinous rice porridges with brown rice increased significantly (p<0.001) with the increase in brown rice content, while the redness and yellowness of the color increased significantly (p<0.001) with increasing in brown rice content. As a result of analyzing the preference in the milk porridge containing brown rice, BRT30, which is non-glutinous rice milk porridge with brown rice, was most preferred at 5.8 in terms of color, while BRT30 was most preferred at 6.2 in terms of fragrance. All samples containing brown rice powder were highly preferred in terms of taste and the overall preference of sweet rice milk porridge was highest for BRT30 (5.8). The overall preference was highest for BGT30 at 6.1 and the preference was generally higher for the experiment groups prepared with sweet rice as opposed to those prepared with non-glutinous rice. Also, the scores for the sensory test were higher when brown rice was added. Therefore, it was concluded that the milk porridge could quickly and easily be prepared with brown rice instead of non-glutinous rice or sweet rice.
