Fruit Waxing & Mix the Right Coat
Coats citrus
Enter your fruit weight, dilution ratio and dose per kg to get the wax solution, concentrate and wateryou need to coat the lot — to cut moisture loss, add shine and extend shelf life.
Mix your wax coating
Next: measure 1,000 mL of wax concentrate into 4,000 mL water, mix well, and apply ~5 mL/kg as a thin uniform film before drying.
Use only food-grade certified waxes (carnauba, shellac, beeswax) at the label dilution; over-coating traps moisture and causes off-flavours. Local food-safety rules apply.

A thin coat that earns its keep
Washing fruit strips away its natural waxy bloom, leaving it open to moisture loss and faster shrivel. A thin film of food-grade wax puts that protection back — sealing the surface, slowing respiration, and adding the bright shine buyers reach for. Citrus, apples and many other crops move through the packhouse waxer for exactly this reason. The art is a light, even coat: enough to protect and shine, never so heavy it turns sticky or off-flavoured.
This tool turns that into numbers. Enter the fruit weight, your product's dilution ratio and the dose per kg, and it returns the wax solution, the concentrate, the water, and the fruit handled — so you mix exactly what the lot needs with little waste. Pair it with the Cold Storage Shelf-Life, Grading Line Throughput and Packaging & Crate tools to plan the whole post-harvest line.

Frequently Asked Questions
What does waxing fruit do?+
A thin food-grade wax coat replaces the natural bloom lost during washing and handling. It seals the surface to cut moisture loss and shrivel, slows respiration, adds shine that lifts shelf appeal, and so extends shelf life. Citrus, apples, cucumbers, capsicum and many other fruits and vegetables are waxed in modern packhouses.
How is the wax quantity calculated?+
Wax is applied at a few millilitres of diluted solution per kilogram of fruit. Wax solution = fruit weight × dose per kg. The concentrate is then split out by the dilution ratio: at 1:4, one part concentrate goes to four parts water, so concentrate is one-fifth of the solution and water is four-fifths. This tool gives all three for your lot.
What is the dilution ratio?+
Wax is sold as a concentrate that you dilute with water before applying — a common ratio is 1:4 (one part wax to four parts water), though it varies by product and fruit. A 1:4 ratio means the concentrate is 20% of the final solution. Always follow the wax supplier's label for your fruit and target coating thickness.
How much wax per kg of fruit?+
Typical doses are a few millilitres of diluted solution per kilogram, often around 2–5 mL/kg depending on fruit size, surface area and the application method (dip, foam or spray-and-brush). Smaller fruit with more surface per kg needs a little more. The tool lets you set your own dose so the figures match your line.
Which waxes are food-grade?+
Common edible coatings include carnauba, shellac, beeswax and approved morpholine-free formulations, used within food-safety limits. Choose a wax certified for food contact and labelled for your fruit and market. The calculator works for any product — you just enter its recommended dilution and dose.
How is the wax applied?+
After washing and drying, fruit is coated by dipping, foam application, or spraying with brush rollers, then passed through a drying tunnel so the thin film sets evenly. Even, light coverage is the goal — too heavy a coat can give off-flavours or a sticky feel, while too little gives poor shine and shelf life.
Does waxing replace cold storage?+
No — waxing complements cold storage; it does not replace it. The coat slows moisture loss and respiration, but temperature control remains the main lever on shelf life. Wax well-cooled, well-graded fruit and keep it cold afterwards. Use the Cold Storage Shelf-Life calculator alongside this to plan the full chain.
Will waxing work for my fruit and units?+
Yes — enter the fruit weight in kg, quintal or tonne, your product's dilution ratio and dose per kg, and the tool scales the solution, concentrate and water to your lot. The same per-kg approach applies to citrus, apples, pears, capsicum, cucumbers and other waxable produce.
Are the figures exact?+
They are solid planning figures for a batch. Real usage varies with fruit size, surface roughness, application method and line losses. Mix a little extra to cover spillage and re-coating, measure what you actually use over a few lots, and fine-tune the dose so your figures match your packhouse.
