Hello, good morning/afternoon/evening/and night. I've been tasked with developing an RTD (Ready-to-Drink) product and have searched for numerous references regarding the process flow and packaging. The product I'm developing is expected to have a pH of less than 3.5 and is intended to be stored at room temperature. Between Tetra Pak and PET bottle packaging options, I am prefer to use PET bottles, but PET bottles cannot withstand hot filling temperatures. After researching Tetra Pak, I'm a bit confused about where to start. What initial steps should I take? Is there someone who can provide some guidance on this matter? Any response would be highly appreciated.
BTW, Our product will use citric acid and ascorbic acid as preservatives.
