At Leaf CleanTech, we develop specialty non-GMO phytase enzymes that unlock bound phosphorus, improve mineral absorption, and make animal feed formulations more sustainable — from poultry and swine to aquaculture.
Phytase is a naturally occurring enzyme that catalyses the hydrolysis of phytic acid (phytate) — an anti-nutritional compound found in nearly all plant-based feed ingredients including cereals, oilseeds, legumes, and grain by-products. In simple terms, it is the biological key that releases minerals and nutrients locked inside plant seeds and makes them available for absorption in the animal's digestive tract.
At Leaf CleanTech, our phytase enzyme — marketed as LEAFPHYT AP — belongs to our broader portfolio of non-GMO specialty feed enzymes developed specifically to address the nutritional and process challenges faced by the modern animal feed industry. Just as importantly, LEAFPHYT AP carries unique activity profiles designed for reliability across different feed formulations and pelleting conditions.
Why it matters: Phytic acid can constitute 60–80% of total phosphorus in plant-based feed. Without phytase, this phosphorus — and the minerals, amino acids, and energy bound to it — is excreted unused, increasing feed costs and environmental impact simultaneously.

Phytic acid (inositol hexaphosphate, IP6) is the dominant phosphorus storage molecule in plant seeds. However, its unique molecular structure — a highly negatively charged ring — gives it an exceptional ability to bind positively charged minerals like phosphorus, calcium, zinc, iron, and magnesium, forming insoluble phytate-mineral complexes that resist digestion.
Beyond mineral binding, phytate also forms complexes with proteins, starch, and lipids, reducing the digestibility of these nutrients as well. As a result, the overall nutritional value of a plant-based diet is substantially lower than the raw ingredient analysis would suggest — a gap that has historically been bridged by expensive inorganic mineral supplementation.
Furthermore, monogastric animals — poultry, swine, and fish — cannot produce adequate endogenous phytase in their gastrointestinal tract. Consequently, supplemental phytase addition to feed is both necessary and economically justified for these species.
Enzymes like phytases play a vital role in liberating bound phosphorus and minerals from phytic acid, boosting their availability for absorption in the digestive tract — reducing anti-nutritional factors that hinder nutrient absorption and promote healthier livestock and better weight gain.
To understand the value of phytase, it helps to follow the enzyme through the digestive process. The mechanism is a sequential dephosphorylation — phytase systematically removes phosphate groups from the IP6 molecule, producing progressively lower inositol phosphate esters (IP5 → IP4 → IP3 → IP2) until free inorganic phosphorus is liberated.
In line with Leaf CleanTech's commitment to biochemical innovation, phytase delivers advantages across nutrition, economics, and environmental sustainability. More specifically, here are the six core benefits that make LEAFPHYT AP a high-value addition to modern feed formulations:
Releases phytate-bound phosphorus, substantially reducing dependence on costly inorganic phosphate supplements like dicalcium phosphate (DCP).
Higher nutrient availability translates directly into better daily weight gain, lower feed conversion ratios, and reduced mortality rates across broiler and swine production.
Phytate hydrolysis releases energy previously tied up in starch-protein-phytate complexes, improving total metabolisable energy of the diet.
Lower mineral supplement inclusion, reduced crude protein requirements, and improved energy density together reduce total feed cost per kilogram of production.
Calcium, zinc, iron, and manganese bioavailability improves markedly — supporting skeletal integrity, immunity, and reproductive health in livestock.
Reduced fecal phosphorus and nitrogen excretion mitigates eutrophication of water bodies — directly supporting Leaf CleanTech's eco-friendly sustainability mission.
Leaf CleanTech's mission centres on promoting environmentally friendly and cost-effective biochemical innovations. In this regard, phytase is one of the most powerful tools available to the livestock industry to reduce its environmental impact.
When phytate-bound phosphorus passes undigested through the animal, it is excreted in manure and enters soil and water systems — a leading driver of phosphorus-based eutrophication globally. By contrast, when phytase is included in feed, the animal absorbs the phosphorus, and fecal excretion drops by 30–50%. Similarly, improved amino acid digestibility reduces nitrogen excretion, addressing another major pollutant from intensive livestock farming.
