Food packaging containing engineered nanoparticles
Food packaging containing engineered nanoparticles PP food storage containers and LDPE bags with Silver Nanoparticles Information given by producer: ‘FresherLonger containers are infused with silver nanoparticles because silver in microscopic particle form is a safe, medically proven antibacterial agent that fights the growth of mold and fungus. In tests comparing FresherLonger to conventional containers the 24‐hour growth of bacteria inside containers, FresherLonger containers was reduced by over 98 percent. ‘ Source: http://www.businesswire.com/news/home/20060308 005281/en/Sharper‐Image‐Introduces‐FresherLonger‐ 005281/en/Sharper Image Introduces FresherLonger TM‐Miracle‐Food: TEM images of Fresher LongerTM packaging PET bottles with Nanoclay In food packaging nanoclay is applied to improve gas barrier properties polymers. y For example p multilayer y PET bottles Imeprm p TM of varietyy of p (Nanocor Inc) allow to both decrease loss of carbon dioxide from the beverage and ingress of oxygen from the atmosphere into the beverage during storage. Production process usually involves sandwiching of the layer of nanoclay in between two layers of polymer, so the nanoclay itself does not have contact with food product directly. directly Source: http://www.foodbase.org.uk//admintools/reportdocuments/346‐1‐ 648_A03063_Final_Report.pdf Food product containing engineered Silica Nanoparticles Nanoceuticals ™ Slim Shake Chocolate Information given by producer: “The natural health benefits of cocoa have been combined with RBC’s NanoCluster™ deliveryy system y to ggive yyou CocoaClusters a technologically g y advanced form of cocoa that offers enhanced flavor without the need for excess sugar.” “The natural benefits of cocoa have now been combined with modern technology to create CocoaClusters. RBC’s NanoClusters are tiny particles, 100,000th the size of a single grain of sand, and they are designed to carry nutrition into your cells.* During the process of creating NanoClusters, pure Cocoa is added to the “Cluster” formation to enhance the taste and the benefits of this treasured food. food.” Source: http://www.nanotechproject.org/inventories/consumer/browse/product s/5107/ TEM images of silica nanoparticles in Nanoceuticals™ Slim Shake Chocolate: Nutraceuticals containing engineered nanoparticles Nano‐encapsulated CoQ‐10 Information given by distributor: ‘Fat Fat‐soluble soluble nutrients are essential to health but are not very bioavailable. That is because in order to be absorbed, they must first be converted in the body to a water‐soluble form. Unfortunately, this "pre‐processing" is imperfect, causing a significant — and sometimes near‐total — loss of active ingredient. A Solgar first, Nutri‐Nano is a patent‐protected nanotechnology that transforms fat‐soluble nutrients into water‐soluble ones — significantly increasing absorption. How? Through surrounding the fat‐soluble molecules with a water‐soluble shell called a micelle, which is only 30 nanometers in diameter. diameter (A nanometer is one‐billionth one billionth of a meter). The micelles carry the fat‐soluble nutrient directly to the absorption site, where it is released and absorbed.’ Source: http://www.myvitanet.com/nutri‐nano‐coq‐10‐3‐1‐ x‐50‐soft‐gel‐solgar.html Silver Nanoparticles Information given by distributor: g y ‘Argentum plus/ Colloidal Silver 10 ppm was first developed by Living Energy Systems in the 1990’s to be absorbed straight into the blood stream when held under the tongue for 30 seconds or into the epidermis when applied topically. Its silver concentration of 10 ppm (parts per million) is comparatively low, but the very small silver particle size of 0.001‐0.002 micron means that in a dose of 5 ml there are more than 200 thousand elemental silver particles present, which are on average made up from 12‐16 ionized silver atoms each, thus creating a very potent silver effect.’ Source: http://www.colloidalsilveronline.com/en/colloidal‐ silver‐10‐ppm‐50‐ml‐spray‐50‐ml‐dropper‐200‐ml‐starter‐ kit.html Argentum Plus Silver in SEM
