Package Dating:
The date on the packaging is not an expiration date, but the manufacturing date. Wysong's special natural antioxidants, nitrogen purging of fats and oils, special light and oxygen barrier packaging, special processing and drying, portion packaging, and cooled storage, makes Wysong the freshest and most nutritious of processed foods. This freshness remains for a year or even more if the products are stored in reasonable, cool conditions. If frozen, the products are highly nutritious for extended lengths of time even beyond this. Our guarantees are carried out through our distributors, and most of them give their dealers a one year guarantee.
