Cheesemaking – A Modern Improvement To An Ancient Craft

The production of soft cheeses (such as Camembert or Brie) requires a more gentle approach than the one taken for molding hard cheeses. The cheese curd is transferred to cheese hoops, and gravity drains them overnight. The curd is then brined to stop the growth of lactic acid bacteria. Once the brining is complete, spores of the Penicillium candida strain are added to the cheese curd. This specific type of mold adds flavor and character to the cheese. However, the selection of mold is not random, and wild molds are a significant problem in this stage of production. The cheesemaker controls surface microflora growth by carefully regulating temperature and relative humidity. Again, this is a very specific process. Wild mold and bacteria are not a welcome addition, and are factors to be controlled. Mold ripened cheese matures much faster than hard cheeses. The entire process is complete within a few weeks or months.

Cheese, like other food products, is graded throughout the maturation process. Part of a cheesemakers skill comes from being able to properly grade the cheese coming out of maturation rooms and sent to retail stores. Obviously environmental factors play a significant role in the final grade of cheese products, and higher grades mean higher prices.

The Airocide NASA PCO technology has a role to play in cheesemaking much like it does in a produce packing house. I have highlighted throughout this piece where air quality issues present themselves during production, but it is important to keep in mind that maturing cheese spends several weeks to several years in a cold storage room. This leaves long periods of time for spoilage to occur. It is also very favorable to performing Airocide tests. I think the cheese industry should be on everyone’s mind, and we should be looking for ways to increase our footprint in this globally pervasive industry. To be a modern improvement on this most ancient craft.

Our US Perishables team has done a fabulous job of this, and even produced a relevant case study. In this particular case the dairy was concerned with the growth of bacteriophage. This virus was infecting the lactic acid bacteria used to ferment the milk, and causing entire vats to spoil. The cost associated with this spoilage was around US $6,000 per batch. I encourage you to read this study carefully, and look for ways to replicate this success. Please share your success stories with us when you do. I would love to feature it in the Airocide Advantage.

Natural ultraviolet light is emitted by the sun in three bandwidths, as UVA, UBC and UVC light, but 98.7% of that light is absorbed by the earth’s atmosphere and the remainder of the UV light that reaches the earth’s surface consists of predominantly UVA radiation. UVC light waves, which are the shortest and most powerful in the UV range, have germicidal properties, and can break down the DNA of microorganisms such as viruses, bacteria, dust mites and other allergens and contaminants.

UVC light has been used for decades to sanitize surfaces and tools in medical labs and to sanitize water in water treatment plants. Many spring water bottlers now utilize UVC light to disinfect bottles and sterilize equipment and increasingly, public water treatment facilities are utilizing UVC technology to upgrade safety standards for drinking water.

Airocide a NASA product goes further with technology and use UVC light and Titanium dioxide (TiO2) to boost the disinfection

Titanium dioxide (TiO2) is the photocatalyst used. A unique process is used to create the patented TiO2 formula that coats the catalyst material. When this material is irradiated with the ultraviolet photons from the lamps inside, hydroxyl radicals and super-oxide ions are formed. These elements will oxidize (reduce to trace elements of carbon dioxide and water) volatile organic compounds (VOC’s) absorbed on the catalyst surface. They will also kill and decompose airborne pathogens. Because the organic material is completely oxidized by this process, the photocatalytic reactor is self-cleaning relative to organic material on the catalyst surface.

With the growing interest in eliminating toxins and allergens from the home environment, the germicidal power of UVC light offers a welcome alternative to chemical cleaning products. Airocide currently available to consumers that can safely eliminate invisible allergens and contaminants in areas that chemical cleaners would be completely unwelcome.

Mattresses, carpets and bedding are perfect breeding grounds for dust mites and other allergy-causing microorganisms that can trigger asthma, hay fever, eczema and other illnesses. Several international studies have concluded that exposure to these allergens in the first two years of life can jump-start these life-long chronic conditions. Airocide destroys the DNA of allergens and microorganisms, such as licefleasmold, bacteria and viruses, including influenza. The benefits of Airocide are obvious for households in which children and pets, as well as adults do not want to risk exposure to either harmful microbes or potentially toxic chemical disinfectants. These products will clean, sanitize and eliminate odors from household surfaces without adding additional pollutants to the household environment.
