Selling broccoli with a shelf life of 2 years, Sam responded.

The reporter found that it is not uncommon to see two-year warranty frozen broccoli on the market, and Sam's Club also sells them. The relevant topic quickly became a hot search. Some consumers called the offline stores of Sam's Club, and the staff said that frozen vegetables are preserved through quick freezing technology, not slow freezing. They are quickly brought down to -18C for freshness preservation, similar to dehydrated vegetables. The nutrients will not be lost and they will not spoil.
