We developed a vegetable alternative to meat patties using Aruncus dioicus var. kamtschaticus Hara (A. dioicus) and used it to generate basic data for the alternative meat market by comparing nutritional and microbiological components with commercially available vegetable and meat patties. Nutrient analysis, microbiological analysis, chromaticity, and texture analysis were performed on substitute meat patties (SMPs) with A. dioicus and commercially available vegetable and animal patties. Among sugars, the contents of fructose and maltose were respectively high in commercial meat patties (CMPs) and SMPs. SMPs were low in saturated and trans-fat, and high in ω-3 fatty acids. The contents (in descending order) of leucine > phenylalanine > threonine > isoleucine were high in SMPs and commercial vegetable patties (CVPs). Qualitative and quantitative findings of Escherichia coli (E. coli) and Staphylococcus aureus were all negative. Our SMPs had high lightness (L*), low redness (a*), and low yellowness (b*). The hardness, chewiness, and resilience of our SMPs were lower than those of other vegetable and animal patties. Considering our results, the method of manufacturing SMPs developed in the present study allows meat to be flavored without significant nutritional differences compared with commercially available CMPs. Our findings provide a base for studies on future meat alternatives.
