In order to develop functional hamburger steak patties, various concentrations of lotus root (Nelumbo nucifera) were incorporated into them. The quality characteristics of the hamburger patties prepared after the addition of 5, 10, 15, 20 or 25% (w/w) lotus root were investigated. The moisture contents of the groups with lotus root were significantly higher than that of the control group. The crude fat and crude protein contents of the control group were higher than those of the other groups.

The cooking loss rate, rate of reduction in diameter, and reduction in thickness of the groups with lotus root were significantly lower than those of the control group. Accroding to the results, lotus root inhibit cooking loss and help to keep moisture after cooking process. No significant difference in the L value was observed among the groups. The a and b values of the groups with lotus root were significantly decreased compared to those of the control group. No significant difference in hardness was observed among the groups. it suggest lotus root didn't affect the texture of hamburger patties. In the quantitative descriptive analysis, no significant difference in the color and fresh odor was observed among the groups. The groups with lotus root were softer than the control group. The groups with 10 to 25 % of lotus root showed higher juiciness and a sweeter taste than the control group. The preference of appearance, texture, flavor and overall acceptability of the groups with 10 to 25% lotus root were higher than those of the other groups, including the control group. In conclusion, lotus root can increase the acceptability of hamburger patties and 10-25% would appear to be the proper amount of it to use.
