Edible “Invisible Packaging” is More Common than You Might Think According to the FDA, modified atmosphere packaging (MAP), which includes so-called “smart” and “edible” types of packaging, has made great strides over the past decade or so, and has “greatly improved the quality and shelf-stability” of otherwise highly perishable produce. This type of packaging can be either “active” or “passive.” Continue Reading…
While I normally do not feature blog posts, this instance is a rare exception, as I thought this Reality Blog report contained quite a bit of worth-while details. In response to one of the videos above, this blogger dug up information about so-called ‘modified atmosphere packaging‘ that could offer one potential explanation for the bizarre plastic-like coating found on lettuce:
“… [M]odified atmosphere packaging (MAP) … involves either actively or passively controlling or modifying the atmosphere surrounding the product within a package made of various types and/or combinations of films … Edible films may consist of four basic materials: lipids, resins, polysaccharides and proteins … The most common plasticizer used to cast edible films is food-grade polyethylene glycol, which is used to reduce film brittleness … Gelatin is … extracted from the boiled crushed bones, connective tissues, organs and some intestines of animals such as domesticated cattle, chicken, and pigs.”
So, could that rubbery peel be a form of sprayed-on MAP, designed to prolong shelf life of fresh produce? As detailed by Reality Blog, this certainly seems like one reasonable conclusion.
Submitted by Alice Vaughn on November 5, 2013 – 7:38 pmNo Comment Fruits and vegetables—apparently even organically-grown varieties—may have cow-, pig-, and chicken collagen coatings on them rather than wax, as well as a number of other unsavory ingredients. Wax was first applied to the skins of fruits and vegetables for longer shelf life hundreds of years ago. Today, that tradition is being carried on with a new generation of chemicals and compounds I’d rather NOT have on my fresh produce… Modified Atmospheric Packaging
