NoName Frozen Orange Juice

Since the pandemic started I found my frozen juice starting to ferment within a week of preparation.Strong fermentation even in the refrigerator. Strange - Poor Quality control? Unknown. The latest prepared juice started to ferment in two days. Product number on container - M377749, best before Sept 14, 2023. This should not happen if juice is properly handled in product preparation and concentrating prior to freezing. Pricing also up 100% since start of pandemic. As a retiree (senior) on fixed income this increase is very concerning. Already prepared juices are also up over 100% and is not a viable option.
