Harvesting Happiness: How Two Ugandan Trailblazers Keep Fruit Fresh Naturally
Meet the Gurus
- Sandra Namboozo – the farmer‑turned‑entrepreneur with a green thumb.
- Samuel Muyita – the farmer‑turned‑tech‑wizard who knows a good snack when he sees one.
What Makes Their Sachet Special?
Imagine a tiny pouch that whispers to your fruit, “Stay fresh, stay juicy, stay you!” These little sachets harness the power of natural preservatives, letting your bananas, mangoes, and apples enjoy a longer, fresher life. It’s like a spa day for fruits.
Why It Matters
- Less food waste = more savings for families.
- Eco‑friendly, no chemicals, no fuss.
- Preserves the flavors that make your taste buds do the happy dance.

When Fruit Turns to Trash
Every year, more than a billion tonnes of edible good stuff literally vanishes into the void. At the same time, tens of millions of people show up on the hunger list. It’s a classic “lose‑win” situation: the poor are starving while the wasted produce just ends up nowhere.
Why it’s Extra Personal for Sandra & Samuel
Growing up on family farms, the duo lived the scene of strawberries slipping off by the barn and the quick kiss‑off of a fresh harvest that didn’t reach market shelves.
What the Someday Warnings Mean to Them
- Rapid Spoilage: Harvested fruit quickly crosses the “good‑to‑eat” window.
- Farmers’ Losses: Every spoiled batch equals a dent in a farmer’s hard‑earned income.
- Fewer Options: Without a proper solution, the burden of food waste only accumulates.
“We Can’t Let It Keep Happen”
There’s no irony in the way these young entrepreneurs dreamed of doing something about it. “We thought, what if we could keep fruit fresh and give farmers a better pot of gold?” they say.
Fighting food waste with plant-based innovation
Meet Karpolax: The Green Tech that Keeps Your Mangoes Fresh
When two agri‑savvy innovators met, they didn’t just talk about the next big tech hack – they actually killed a problem that has been turning fresh fruit into mushy mush for ages. Their mission? To give fruit a natural, plant‑powered boost that lasts up to 30 extra days on the shelf.
Why the Dynamic Duo?
- Muyita – a soil‑loving scientist who knows the smell of earth.
- Namboozo – a farmer who’s seen the heartbreak of spoiled mangoes.
They both grew up in agriculture, spot‑on identified the same challenge, and voilà – Karpolax was born.
What Is a Karpolax Sachet?
Imagine a tiny, biodegradable pouch packed with volatile organic compounds (VOCs) from
- Cloves
- Lemongrass
- Eucalyptus
- Wintergreen
These are the same plants that give your tea a zing, but here they take on the role of slow‑ripening warriors, fighting off mold and bacteria . The sachets are 100% natural, leakage–free, and release their magic slowly – perfect for each fruit type.
Proof‑In‑Action
Phase 1: Uganda’s NARO – they tested mangoes, and the results blew the competition:
- Fresh for 33 days vs. 11 days for untreated fruit.
Since then, the tech has gone on to test bananas, apples, oranges, and is in the pipeline for pineapples, berries, and capsicum. The future looks juicy!
How Does It Work?
It’s super simple:
- Place the sachet in the fruit box.
- When you open the box, the active ingredients are released.
- The fruit stays fresh for up to 30 days longer.
Namboozo explains it as “the little sachet that kicks fruit’s preservative game to the next level.”
Why Kicking It Up a Notch Matters
With the Young Inventors Prize 2025 (aka Tomorrow Shapers award from the EPO), Karpolax joins the top ten innovators worldwide. It’s a badge of honor that shows their breakthrough is not just cool but needed – a real step toward greener, more sustainable food storage.
So the next time your box of mangoes looks like a disaster, remember the little fungi‑busting sachet you could’ve had on standby. It’s science, it’s green, and it’s blessed by top innovators.
Empowering farmers with science-driven solutions
From Classrooms to Countryside: Meet the Innovators Behind Karpolax
While the halls of Makerere University buzzed with student chatter, two bright minds—Aisha Namboozo and her partner—weren’t just taking exams. They were brewing a different kind of chemistry: turning science into a real‑world tool for farmers.
What Sparks Spark?
- They knew that the biggest users of their research weren’t scientists in labs, but the plow teams in muddy fields.
- “We wanted a product that didn’t just sit on a page, but sat next to a fresh banana,” Aisha remarks.
- Karpolax, born in 2020, was designed to be cheap, clever, and straight‑to‑the‑point.
Adoption Tales
- By 2023, the gear had spread like wildfire across 100 farmers, 20 exporters, and 250 bustling market stalls.
- These everyday heroes—soil‑tenders, merchants, and growers—now have a better way to keep their produce fresh, saving both time and money.
- And the success story is just getting louder; plans for Kenya and Rwanda are on the horizon.
Why It’s a Game‑Changer
- Karpolax hits the sweet spot of UN’s Sustainable Development Goals: Zero Hunger (SDG 2) and Responsible Consumption & Production (SDG 12).
- By cutting food loss, it boosts farmer incomes while keeping the planet healthier.
- Low‑cost and eco‑friendly, it fits people’s budgets and the earth’s needs—like a win‑win partnership in a single, little device.
Takeaway
What began as a student project is now a beacon of hope for farmers across East Africa. With a little ingenuity, a lot of hard work, and a dash of humor, Karpolax ensures that science gets back home to where it was born: to people who need it most.
Building from the ground up
From Zero to Hero: How Two Young Innovators Made Fruit Preservation Pop
When you were told “Start from scratch and hunt for that funding yourself,” the duo early on seemed a bit nervous—until they found a few kind-hearted mentors at their university. Those supervisors swooped in like a safety net, instantly boosting their confidence that you could actually pull this off.
- Funding Reality: “Starting from zero, you need to source the money yourself,” Muyita says. “It felt wild at first, but we’re rolling on our own.”
- Mentor Magic: “We had some supervisors from the university who supported us and made us feel confident that we could succeed.” This felt like getting a squad of cheerleaders, only they’re scientists.
- Big Dreams: Namboozo lays out the end goal: “Our vision is to be the world’s leading fruit and vegetable preservation company.” The ambition is so high it could probably beat the sale of a single avocado in a week.
- Word to the Wise: Muyita is all about self‑belief: “Believe in yourself. When you believe in yourself, believe in the fact that you have what it takes to make it. You will indeed make it.” It sounds like a perfectly timed pep talk from a motivational speaker, but it’s actually real.
Between turning diced peaches into tomorrow’s snack shelf‑life and convincing their mom that ‘fancy sauce’ really is a viable product, these innovators have crafted a story that’s as sweet as their preserved fruit. Their next stop? Turning the world’s garden glossy goodies into a global food brand—because let’s face it, who wouldn’t want dishes that keep their dinner fresh for weeks?
