The Storage stability for 4 weeks in 2 type packages e.g. Oriented Polypropylene package and aluminium pouch. Oxidation of 4% Eri silkworm prepupae cookies was increased with a longer storage in both packages as can be seen in the increment of TBA and peroxide value. But the Oriented Polypropylene package (OPP) has TBA and peroxide value more than aluminium pouch. Therefore aluminium pouch was convenient for Eri silkworm prepupae cookies.
