In the fresh produce section of Star Supermarket in Hamburg, 72-year-old Mrs. Hanna bends down to pick a head of broccoli. Her fingertips touch the leaves — droplets slide along the veins, the tips slightly curled, like vegetables freshly harvested from a farm. She smiles at the shelf staff: “These vegetables are even fresher than the ones from my backyard!”
A year ago, this scene would have been unimaginable: the leafy greens section at Star often displayed wilted lettuce, the strawberry section sometimes had faint moldy odors, and customers would pinch wrinkled fruits and ask, “Were these really delivered today?”
In Europe, the “freshness competition” in supermarkets has reached a fever pitch. According to the German Retail Association (HDE) 2024 data, due to transportation losses and in-store storage conditions, the overall loss rate of fresh produce in European supermarkets remains high at 12%-18%, while 63% of consumers cite “insufficient freshness” as the primary reason for abandoning fresh purchases.
Leveraging “medical-grade precision + food-grade safety,” LuftGlück addresses key pain points in fresh produce humidification with three technical solutions:
Precise Humidity Control: Equipped with intelligent dual temperature-humidity sensors, the system automatically adjusts mist output based on produce type — leafy greens (85%-95% RH), berries (90%-95% RH), seafood (60%-70% RH) — with an error margin of no more than ±5% RH.
Delicate Freshness Protection: Nano-level atomization produces droplets only 3-5 microns in diameter, evenly coating fruits and vegetables without damaging leaves or wetting price tags.
Safe and Long-Lasting: A hard water filtration system ensures atomized water meets EU drinking water standards, with a 24-hour continuous operation failure rate below 0.3%.
The Star fresh produce purchasing manager recalls: “With regular household humidifiers, either the mist was too coarse and wet the packaging, or local over-humidification caused strawberries to mold. LuftGlück’s equipment is like installing a ‘smart air conditioner’ in the fresh section — leafy greens stay upright, berries resist mold, and overall product freshness is effectively maintained.”
Six months later, Star supermarket recorded:
Significant reduction in losses: Leafy greens loss rate dropped from 16.8% to 3.9%; strawberry shelf life extended from 2 to 7 days, substantially reducing waste.
Increased customer loyalty: Monthly foot traffic in the fresh section grew by 28%, and returning customers accounted for 57% (industry average 39%).
Optimized operating costs: Reduced markdowns and waste handling, saving tens of thousands of euros per month per store. The 15 devices consume approximately €450–€900 per month, depending on operating time and mode, or about 2–5 kWh per device per day, keeping overall energy costs reasonable and manageable.
LuftGlück’s devices are called “Freshness Translators” because they not only solve the technical problem of maintaining humidity but also convert freshness from a vague sensory experience into a measurable, perceivable, and trustworthy business value.
As a representative of a European retail fresh produce committee stated: “When customers can judge freshness by whether leaves are upright or droplets remain on the fruit, and when supermarkets can demonstrate performance with lower loss rates and higher repurchase rates, industrial humidifiers go beyond being mere tools — they are bridges connecting farms to tables and vital instruments in competitive differentiation.”
True freshness management does not require fancy slogans — it only takes a professional device that understands, protects, and locks in freshness. If you want the fresh produce on your shelves to “pause time,” visit Star’s fresh section — touch the dewy leaves, count the few discarded fruits, and you’ll understand: maintaining freshness keeps customer choice, and safeguarding freshness ensures the future of the supermarket.
