researchers at Virginia Tech said:

LED
lamps can not only reduce energy consumption
. They also give milk a better taste.
”When exposed to a specific light source, the flavor of the milk changes. Fresh milk should taste sweeter and richer, but people always use words such ascardboard

,
"

"
and
"

"
to describe milk exposed to traditional fluorescent lamps.researchers found that while the new
LED
can reduce these negative effects, efforts are still needed to study and improve packaging.
Susan Duncan
, a professor of food science and technology at Virginia Tech's School of Agriculture and Life Sciences, said
"
We hope to find a way to keep milk fresh as the raw milk our grandparents drank. She published the findings in the journal Dairy Science.
”When milk is exposed to fluorescent lamps, one of the nutrients,
,
B2 oxidizes. This reaction not only causes changes in taste, but also reduces the nutritional value of milk.Duncan
tests showed that milk was stored in traditional clear plastic bottles, and these reactions slowly occurred within two hours. Opaque packaging prevents light from affecting the production of
B2
other nutrients.Duncan
series of experiments at Virginia Tech's Sensory Assessment Laboratory showed that consumers preferred milk under the new
LED
light source to milk exposed to fluorescent lights.funding for the project was funded by dairy farmers through funding from the National Dairy Council, with the full support of the USDA Incubation Program and the Virginia Tech Agricultural Pilot Station.Duncan
more needs to be done to improve packaging to prevent changes in milk flavor. If packaged in traditional high-density polyethylene transparent bottles, milk is more likely to oxidize and change in flavor. But her tests also showed that the flavor of milk would not change much if high-density polyethylene or plastic
PET
containers with light-absorbing masterbases were used, and consumers thought the milk would taste fresh.Duncan
that while packaging costs have increased compared to traditional bottles, it is also worth it to maintain the best taste of milk.The source of this
