Nope. Foods in trash are exposed to bacteria and oxygen compared to your steam cooked vacuum packed tikoy. They go bad faster..
Nakabili na rin ako ng ganyang tikoy at kinain ko kahit more than 2months expired na. Prito mo lang with egg, okay na

Most of the microorganisms got killed during steaming and vacuum packing removes oxygen to prevent bacterial or mold growth. Masasabi kong maayos ang pagkakapack nyang tikoy kaya sure ako na tatagal yan... Mas maayos pa yung packaging nyan kumpara sa packaging ng mga sikat na meat products katulad ng purefoods.
"How Long Do Rice Cakes Last? Properly stored, unopened rice cakes will last for 1-2 years past the printed expiration date. Once opened, if stored correctly in an airtight container, they will last for about 1 week. If not stored properly, opened rice cakes will only last a few days."
Nian Gao tawag ng mga intsik jan sa tikoy at normal na pinapatgal nila yan sa ref. Kahit 6-12months at may amag pa kinakain nila. Tinatangal lang yung amag tapos okay na

Pero ako, di ko kakainin yan kapag napansin ko kung iba na kulay, amoy, texture or may amag na kahit matagal pa expiry date.
