Shelf Life and Display Case Lighting
PROMOLUX Lighting International makes specialized lighting for food display cases.
You can combine the merchandising advantages of superior color rendering with the benefits of longer shelf life and reduced commercial losses that result when perishables are protected from harmful heat and light emissions.
What would longer shelf life mean to you?
Extending the shelf life of perishable foods such as meat, seafoods, fruit and vegetables and other fresh goods on display translates directly into fewer discards and higher profits.
The Promolux foodlighting advantage is clear:
Other food lighting applications include bakery and dairy displays, deli and food service displays, produce and floral displays, and beverage displays. Promolux display lamps also improve non-food visual marketing displays such as art displays, cosmetics and fine fabrics, especially where superior color balance and protection of colors and surfaces are important.
The Balanced Spectrum technology built into Promolux lamps is a proprietary phosphor-coating that produces natural, balanced light and filters out damaging ultraviolet, infrared and visible spectrum wavelengths.
Retail food displays can be provided with superior showcase illumination while minimizing damaging visible spectrum and UV wavelengths. Promolux food safe lighting helps prolong the shelf life of perishable foods and other light sensitive merchandise.
Promolux Safe Spectrum food lighting is made to reduce photochemical oxidation and improve the safety of foods and other sensitive goods that must be displayed under lights.
An easy installation of Promolux lamps will turn your display lighting into an asset that also helps protect the quality of valuable merchandise in all food displays.
Food Safe Lighting is Profitable for all Perishable Food Displays
Supermarket meat displays, deli displays with sliced meats and salads, and fresh seafood displays all suffer color distortions when general purpose lighting emits damaging UV and visible spectrum radiation. Poor lighting can slow sales, leaving fresh foods on the shelf to age and deteriorate.
Heat and light radiation from conventional lighting can also unnecessarily shorten the shelf life of sensitive perishables by causing damage to natural fresh food colors and texture and by accelerating bacterial growth, spoilage, and decomposition. Even packaged food displays can suffer from heat and radiation damage, and baked goods on display can dry out and lose their fresh baked aromas quickly under lighting that produces too much heat. With Promoluxfood safe lighting, you can prolong shelf life of all food items, particularly red meats and produce.
Low Radiation Balanced Spectrum Lighting is Food Safe
Fresh foods displayed under lights in display cases always suffer discoloration and other damage by exposure to the effects of heat and light radiation from improper display case lighting. Everyday lighting used to illuminate special display cases is often too bright and produces washed out colors with strong yellow and green portions of the visible spectrum. See more details about the relationship between radiation from light sources and food shelf life.
Promolux Safe Spectrum specialty lighting has been designed specifically for illuminating fresh food displays and has been tested in food science laboratories and universities. Promolux lamps are easily installed in your meat display fixtures for immediate visual impact.
Why install Promolux Safe Spectrum lighting for your display cases?
Supermarkets must constantly dispose of large quantities of fresh foods from their shelves due to photo oxidation and discoloration. Promolux low emission lamps help protect the fresh colors of meats, seafoods and produce. By simply installing Promolux Safe Spectrum lighting, grocers and food retailers can reduce financial losses incurred by having to dispose of foods that are have lost their fresh flavors or those that still quite safe but have lost their consumer appeal due to discoloration from photo oxidation. The applications are as varied as your food shelves.
Supermarket Meat Display Cases
The shelf life of fresh meat such as beef, pork, chicken, and ground meat is reduced by at least 10% every time the meat’s surface temperature increases by a degree beyond its optimal storage temperature. If the surface temperature rises from -1.5°C to 2°C, the shelf life of meat can be cut in half. As the intensity of the lighting increases, the surface temperature of displayed meat also increases proportionately, regardless of whether the lamp is an incandescent or a cool white fluorescent lamp.
Changing the light source can be enough to maintain optimal temperatures, and to protect fresh meat displays from harmful UV radiation. In a 28 day study, steaks displayed under low UV Promolux lamps and those under regular lamps blocked by Promolux filters maintained virtually the same freshness and bright red color as beef stored in the dark.
Retail Deli Display Cases
Display case lighting causes fading in cured and processed deli meats such as ham, bacon, salami, pastrami, and pepperoni. Packages of deli ham that are exposed to merchandiser lighting become faded while those that are protected from the light remain bright pink.
Commercial Seafood Display Cases
Display case lighting generates heat and UV radiation which shortens the shelf life of seafood. As the surface temperature of fish and seafood rises, harmful bacteria grow exponentially and water is lost though dehydration, leading to lower profits when the seafood is sold by weight.
Grocery Produce Display Cases
Regular fluorescent lights cost up to $1 per foot per day in the produce department due to dehydration, shrinkage, and overripening. Lettuce and soft fruits are extremely sensitive to the harmful effects of lighting. UV radiation causes potatoes to turn green and develop high levels of the poison solanine.
Supermarket Bakery Display Cases
Promolux lamps extend bakery shelf life by up to 50% by preventing dehydration which makes bakery products prematurely stale. Under regular lighting, cream turns rancid, food coloring fades, and chocolates form a white surface film. Bakery products also have a shorter shelf life under retail lamps that dehydrate them and make them prematurely stale.
Grocery Store Dairy Display Cases
Milk develops two types of off-flavors and milkfat turns rancid when exposed to 4 minutes of sunlight, or 4 hours of supermarket fluorescent lighting. Many nutrients are lost in this process, including riboflavin and vitamin D.
Retail Floral Display Cases
Floral display case lamps accelerate the decomposition of cut flowers, causing them to wilt prematurely. Spring flowers and roses are particularly sensitive to UV radiation.
Commercial Beverages Display Cases
Beer, wine, and fruit juices must be protected from any light source that emits UV radiation as light will cause these beverages to smell and taste skunky if they are stored in clear bottles.
Supermarket Food Service Buffet Counters
Display lamps on hot food buffet tables emit radiation that continues to cook the food, drying it out, reducing its holding time, and leading to spoilage. On cold buffets and salad bars, leafy green vegetables and fruit wilt and jello becomes rubbery.
Grocery Store Packaged Foods
Light can damage other foods, such as vegetable oils and any food packaged in clear glass jars.
True color rendering is very important for many non-food applications including art, cosmetics, jewelry, leather, glass, china, clothing, and carpets. Many of these products will fade when exposed to UV radiation.
