Why a P+V container works
Food generally deteriorates due to certain recognised factors:
Some of these we can control ie temperature by storing food in a fridge or completely stopping the growth of any microbes by freezing, light by storing in a fridge where there is no light. Some of these we cant control ie enzymes as these are naturally prevalent in foodstuffs, some more than others.
Generally we all use fridges and freezers. What Pac ‘n Vac boxes add to the list is to control the amount of oxygen and air that the foodstuff is exposed to. By expelling air from the box the foodstuff contained in the box stays fresher for longer. In addition the lack of presence of atmospheric air inhibits the growth of microorganisms.
Pac ‘n Vac had the boxes tested at Public Health England for Aerobic Colony Count and Enterobacteriaceae. It is known that chicken is especially susceptible to microbial activity (see http://www.food.gov.uk/science/microbiology/campylobacterevidenceprogramme/retail-survey) so the tests were carried out to include this product. The product was tested when it was delivered under strict temperature conditions and then re-tested at the end of 5 days – the normal maximum cycle of keeping supermarket fresh product. The results showed that the colony count increased at a substantially faster rate when there was no vacuum present. Indeed after 3 days some products particularly chicken were beyond their recommended shelf life whereas if they had been stored in a Pac ‘n Vac box they would have lasted at least five more days. NOTE the charts below are the average for all tested products – some products last longer than others – see our estimated list of products.[/fusion_text]
As you squeeze the air out of the container you create high pressure inside the container forcing the silicone valve open. When the hand pressure on the container is released the resultant higher pressure outside of the container forces the valve shut making a seal and ensuring a vacuum[/fusion_text][/fullwidth][fullwidth background_color=”#000000″ background_image=”” background_parallax=”none” enable_mobile=”no” parallax_speed=”0.3″ background_repeat=”no-repeat” background_position=”left top” video_url=”” video_aspect_ratio=”16:9″ video_webm=”” video_mp4=”” video_ogv=”” video_preview_image=”” overlay_color=”” overlay_opacity=”0.5″ video_mute=”yes” video_loop=”yes” fade=”no” border_size=”0px” border_color=”” border_style=”solid” padding_top=”50″ padding_bottom=”40″ padding_left=”0″ padding_right=”0″ hundred_percent=”no” equal_height_columns=”no” hide_on_mobile=”no” menu_anchor=”” class=”” id=””][imageframe lightbox=”no” lightbox_image=”” style_type=”none” bordercolor=”” bordersize=”0px” borderradius=”0″ stylecolor=”” align=”center” link=”” linktarget=”_self” animation_type=”0″ animation_direction=”down” animation_speed=”0.1″ hide_on_mobile=”no” class=”” id=””] [/imageframe][separator style_type=”none” top_margin=”25″ bottom_margin=”25″ sep_color=”” border_size=”” icon=”” icon_circle=”” icon_circle_color=”” width=”” alignment=”center” class=”” id=””][fusion_text]
Tested by Public Health England
In 2014 we submitted our range of boxes for testing by Public Health England, the main Government food product testing site in the UK. Product was purchased from a supermarket and each item was split in two and one half put into a Pac ‘n Vac box and in the other in a standard plastic food container readily available in the shops. This was then delivered to PHE for testing and the results prove beyond doubt that the Aerobic Colony Count and Enterobacteriaceae readings were significantly reduced in the Pac ‘n Vac box with its vacuum. This means that foodstuffs last substantially longer in one of our boxes than in a standard box. See our list of main products that benefit from being stored in our boxes (LINK include coffee, paint etc) – ALL products that deteriorate being in contact with air will benefit from our boxes.[/fusion_text][/fullwidth]
