Preserving Ice Cream Perfection

Enhance Flavor and Extend Freshness with Promolux Lighting

Light and heat accelerates the rate of lipid oxidation, a chemical reaction between oxygen and unsaturated fatty acids which affect the smell, taste and appearance of any food containing milk fats, such as ice cream.

Since ice cream tends to have a high fat content, it is particularly vulnerable to strong supermarket lighting and the off-flavor effects of lipid oxidation. Nutritionally, lipid oxidation destroys riboflavin, pyridoxine, and vitamins A, D, B12, and C. Oxidized ice cream taste rancid, stale, metallic, or even cardboard like. Since Promolux lighting minimizes the emission of damaging visible spectrum and UV wavelengths, they will minimize these flavor changes in ice cream.

Reviving Dessert Brilliance

Preserve Vibrant Colors for Ice Cream and Gelato

Most artificial lighting sources trigger photochemical reactions that cause the bright colors of food dyes to fade. Because of this, ice cream and gelato will quickly discolor when exposed to strong light. In the case of ice cream cakes, the wrong lighting can cause white decorations or icing to appear yellow, while red decorations will seem dull or even fade to pink. Regular lights tend to emphasize the yellow and green spectrum which does little to showcase the naturally vivid colors of icings and other decorations.

Crystalline Perfection

Enhance Ice Cream Cake Presentation

Heat and radiation from regular lighting also causes the top surface of ice cream cakes to melt, separating the water in the ice cream from the other ingredients, especially when stored in cardboard boxes with transparent tops. When this water refreezes, ice crystals form within the ice cream cake or on the inside surface of the box.

Promolux lighting emits a more balanced range of wavelengths, including more of the red and blue wavelengths and more moderate levels of the damaging yellow and green wavelengths than regular lighting, reducing ice crystal formation and revealing the bright colors of each flavor and topping.

Commercial Ice Cream Display Lighting in Freezer Merchandisers

When commercial ice cream displays are exposed to improper LED lighting commonly found in freezer dairy merchandisers, ice crystals can form and the light initiates two chemical reactions which result in off-flavors.

Promolux Safe Spectrum LEDs emit lower levels of heat and ultraviolet radiation than regular lamps, thus reducing the rate of chemical reactions in ice cream and gelato displays.

The result is improved product integrity, superior color presentation and improved customer satisfaction. Promolux Platinum color formula lamps and LEDs are ideal for ice cream shops and gelato displays where the colors and flavors are as unique as each store!

When ice cream or gelato is exposed to sunlight or to the lighting commonly found in frozen dairy display cases, the light initiates two chemical reactions which result in off-flavors and the loss of nutrients.

First, whey proteins composed of amino acids containing sulfur degrade and break down, producing “sunlight” flavors reminiscent of burnt feathers or burnt hair that can last for two to three days.

In the second reaction, the unsaturated fatty acids in milk lipids (milk fat triglycerides / triacylglycerols) become oxidized, producing malodorous carbonyl compounds that taste metallic or cardboardy and do not dissipate.

Ice cream tends to have a high fat content, making it particularly vulnerable to strong supermarket lighting and the off-flavor effects of lipid oxidation.

In one study, vanilla ice cream that had been stored directly under high-intensity lighting turned rancid, developing high levels of dimethyl disulfide and hexanal, two indicators that the ice cream had been damaged by light.

I started looking for better lights because on our ice cream we were constantly getting a frost build up and high condensation. I found Promolux on the Internet and they gave me the name of a distributor in my area. When I put Promolux bulbs in my case, I no longer had any trouble with frost build up or condensation. And with Promolux – customers often comment to me that the colors of my ice cream are so bright and vibrant – no matter which flavor. I am in the process of opening another store, and let me tell you – one of the first things I am doing is yanking the regular bulbs out of my case and replacing them with Promolux!

Ice Cream Flavor Changes in Retail Ice Cream Showcases

Factors that affect the rate of lipid oxidation in ice cream and gelato cases include:

• the intensity of the light,

• the wavelengths (spectrum) present in the light,

• the distance between the light source and the ice cream/gelato product,

• the material of the container,

• the amount of surface area exposed to the light,

• the holding temperature of the ice cream and the display case,

• the fat content of the ice cream and

• the duration of light exposure.

While ice cream in light-transmissible plastic containers is most vulnerable, ice cream in paper cartons can also be affected when the cartons are exposed to intense light for long periods of time.

Since Promolux lamps minimize the emission of damaging visible spectrum and UV wavelengths, using Promolux lamps will minimize these flavor changes in ice cream.

Ice Crystal Formation in Ice Cream

UV radiation easily penetrates cold atmospheres and creates heat at the surface of frozen packages. Heat and radiation from regular supermarket fluorescent lighting can cause the top surface of ice cream to melt, separating the water in the ice cream from the other ingredients. When this water refreezes, ice crystals form within the ice cream.

Ice cream can also become discolored when exposed to light. Ice crystal formation and discoloration can also happen with ice cream cakes, especially when these are stored in cardboard boxes with transparent tops. If the ice cream cake is decorated, the wrong lighting can cause white decorations or icing to appear yellow, and red decorations will seem dull.

Promolux lamps emit a more balanced range of wavelengths, including more of the red and blue wavelengths and more moderate levels of the damaging yellow and green wavelengths than regular fluorescent lighting, reducing ice crystal formation and revealing the bright colors of each flavor and topping!

This season, make a splash and showcase all the bright yummy colors and flavors of your ice cream display! Request a quote for Promolux Platinum color formula lamps and transform your ice cream shoppe into an oasis of tropical flavors and colors.

Merchandising Ice Cream Cake Showcases

Did you know that ice cream cakes are vulnerable to the effects of UV and visible spectrum radiation from commercial LED display lighting? Even though they are kept in refrigerated displays, the direct light from the case lights can cause all sorts of problems, including the fading of frostings, formation of ice crystals and the spoilage of creams and milkfats.

When it comes to illuminating ice cream merchandisers and gelato and frozen yogurt coolers, Promolux low UV and balanced spectrum lights and LED lighting solutions are the only way to go!

Promolux lamps prevent the fading, development of off flavors and ice crystals from occurring.

Ice Crystal Formation on Ice Cream Cakes in Commercial Freezers

UV radiation easily penetrates cold atmospheres and creates heat on the surface of frozen packages. Heat and radiation from regular lighting causes the top surface of ice cream cakes to melt, separating the water in the ice cream from the other ingredients, especially when the ice cream cakes are stored in cardboard boxes with transparent tops. When this water refreezes, ice crystals form within the ice cream cake or on the inside surface of the box.

Off Flavors of Ice Cream Cakes

Light and heat accelerate the rate of lipid oxidation, a chemical reaction between oxygen and unsaturated fatty acids which affect the smell, taste and appearance of any food containing milkfats, like ice creams.

The higher the fat content, the more vulnerable the ice cream is to the off-flavor effects of lipid oxidation. Nutritionally, lipid oxidation destroys riboflavin, pyridoxine, and vitamins A, D, B12, and C.

Oxidized ice cream taste rancid, stale, metallic, or even card board like. And no one wants their ice cream or favorite gelato to taste weird!

Fading of Ice Cream and Gelatos

Most artificial lighting sources trigger photochemical reactions that cause the bright colors of food dyes to fade including ice cream and gelato which quickly discolors when exposed to strong light. If the ice cream cake is decorated, the wrong lighting can cause white decorations or icing to appear yellow, while red decorations will seem dull or even fade to pink. Regular fluorescent lights and LEDs tend to emphasize the yellow and green spectrum which does little to showcase the naturally vivid colors of icings and frozen yogurts.

In fact when it comes to presentation and boosting sales, the best thing any business can do is maximize the visual appeal and freshness of the items on display and that’s precisely where Promolux lamps and LEDs provide superior lighting.

Promolux Cake Installation

To the right hand side you can see a cake display that has had half of its lights replaced with Promolux. The difference in color and visual appeal is quite apparent. This retailer switched all of their perishable food cases to Promolux because they understand the value in eliciting sales and cutting waste and the role Promolux lamps has in enabling them to do just that!
