TOKYO -- Anyone who has ever fished veggies or meat out of the fridge, only to find hopes for a homemade meal wilt like rotten lettuce understands the challenge of keeping food fresh. But thanks to new packaging, rearing and shipping technologies, people may be making fewer last-minute calls for pizza.
Take vegetables. Even if you buy your greens direct from the farm, they begin to wither in the refrigerator once you get them home. Plastic wrap helps ward off the decay, but it can also create condensation. The moisture is nice if you're a mold looking for a place to grow, not so good if you're a human who prefers a crisp, tasty leaf. Retailers face the same problem.
