The botanical antimicrobial agent prepared from citrus fruits (BAAC) was prepared to provide inhibitory ability to packaging paper The BAAC diluted in 0.5% and 1% starch solution respectively was applied to packaging paper by the thin coating technique. The antimicrobial packaging paper displayed great inhibitory effect against the putrefying microbes including fungi, yeast and bacteria. Tn addition to antimicrobial activity of the packaging papers, their physical properties such as tensile strength, burst strength, tear strength and bending stiffness could be improved by simultaneous treatment with starch. Both the item packaging by tissue paper and the outer packaging by corrugated boxes, which were treated by the thin coating of BAAC and starch, exhibited great ability in preserving freshness of stored mandann oranges. The more treatment of BAAC was made in the packaging paper, the greater freshness-preserving ability was generated.
