A nectar-sweet peach; crisp, emerald green lettuce; anavocadowith flesh so soft and blemish-free it’s as if it were on Accutane—perfect produce is one of life’s purest, simplest delights. I never thought I’d be one of those adults who said things like “fruit is nature’s candy,” but wow, how a succulent grape can change a man. Sadly, pristine fruits and vegetables are about as ephemeral as they are wonderful, passing through the veil between the realm of the ripe to the rotten at a moment’s notice.
Celery goes limp, herbs turn into slime, potatoes and avocados oxidize. Unfortunately, all of this spoilage adds up: Americans at home throw out 27 million tons of food each year, equaling around $144 billion of waste. Obviously, no single person or tool will change this, but at Epi we’re always looking for ways toreduce waste in the kitchen.
Zwilling公司你可能知道的刀,recently released a new storage system called the Fresh & Save, which consists of a handheld vacuum sealer and specially designed lids and bags formulated to extend the shelf life of fresh produce, leftovers, and other spoilable comestibles. I was interested to see if this home vacuum storage system could really hold up to the claim that it could keep food fresh for five times longer than other non-vacuum options.
I used the Zwilling Fresh & Save system for a few months; here’s what I found.
Vacuum preservation works because of science
This wasn’t a test to see if vacuum sealed food lasts longer,because we already know that it does. By removing the air from a sealed container, you are removing one of the primary causes of food spoilage: oxygen. Exposure to oxygen causes oils to go rancid, turns fruits like apples and avocados brown, and is necessary for aerobic bacteria to thrive. Vacuum sealing prevents any oxygen from touching the food, and as a result, produce, nuts, and leftovers will stay fresh longer when they’re sealed off from air. (Please note that vacuum-sealing some food isn’t safe;read herefor a list of what not to vacuum seal.)
The real test here was how good the Zwilling Fresh & Save seal really was.
How the Fresh & Save works
There are two different Fresh & Save starter sets: one comes with glass containers and the other hard plastic. Each set includes one medium (900 milliliter) and one large (2 liter) vacuum storage container, two small and two medium reusable plastic vacuum bags, and a rechargeable handheld vacuum sealer. Zwilling also sells additional storage containers and vacuum bags in various sizes
I tested both the lightweight plastic and thick borosilicate glass vacuum storage containers. Both sets are microwave-, freezer-, and dishwasher-safe. Both styles come with a hard plastic lid fitted with a circular rubber plug where you attach the vacuum sealing device and remove the air from the containers.
The BPA-free plastic bags are similar to your standard-issue freezer bag; however, Zwilling intends for people to use them more than once. They are freezer-safe, dishwasher-safe, and heat resistant enough for sous vide applications. Unlike many standard vacuum sealing bags that rely on vacuum sealers that suck air out of the top opening, the Zwilling system is fitted with a circular vacuum port. You must close the bag completely before attaching the sealer to the port and removing the air.
