Ultraviolet light could extend shelf life of food and reduce waste

Food waste is a major problem facing today’s society. LSU AgCenter food scientists are working on ways to extend the shelf life of food products, which will help reduce waste. LSU AgCenter reporter Craig Gautreaux has the story from the LSU campus.

Clear message, clear structure, easy to understand, thank you

[@aungphonekyaw8955]

What kind of uv lamp should be use.

[@merceehh]

Does it work for poultry?

[@arneaiking8876]

Yes, we supply those systems to the poultry industry also.

[@stephenketcher1]

@@arneaiking8876 Whats would you recommend for a juicery? We wish to move away from thermal pasteurization. Thanks

[@noleenmagora7845]

How much is this uv sterilize

[@arneaiking8876]

Simple handheld systems are avialable from US$350. Fully automated post-harvest systems for industrial settings may set you back US$100,000 or more.

What if the food's been exposed to UV light for a year? Is it still preserved or is it gonna have side effects? Just trying to do research for homework.

[@arneaiking8876]

Nope. A few seconds is best. Long term exposure can give damage to the food, sort of like sunburn.

Does it work for kiwi?

[@arneaiking8876]

Yes, the CleanLight technology is also used on kiwis, and other siemilar produce. Ask us for details: [e-mail]

HELLO WILL THIS METHOD WORK ON MILK PRODUCTS BEFORE THEY PACK TO INCREASE SHELFLIFE????

[@arneaiking8876]

Yes, milk, wine, juices, etc (Drinkwater is most common. It is clear, so you can use standard lamps. Milk and wine are more opaque, so they require stronger lamps/ and/or lower flowrates.)

[@shintran]

It will work for clear liquid, i see normally they use it for water, but for milk, i am not sure. I work in a juice factory, UV light can only control the bacterial in the air on top of the surface of juice but not the juice itself

[@stephenketcher1]

@@shintran whats the name of the machine used for that in your juicery? We use thermal pasteurization but wish to move from that. Thanks

[@shintran]

@@stephenketcher1 You can investigate in the HPP (High pressure pasteurizer) which will work with pre-packed juice. But UV light will not work in the case of juice, unless it's clear liquid.

the sound is not good I am quite disappointed
