Liver gets most of the attention in organ powders. Heart gets less, even though it is one of the three organs buyers ask us for most, alongside liver and kidney.
It is also harder to make well. Heart is a high-fat muscle, and the fat changes how it mills, how it handles and which spec a formula should call for. This guide covers what a formulator or buyer needs to know before specifying bovine heart powder.
What does bovine heart powder contain?
Heart naturally contains coenzyme Q10 (CoQ10). That is the composition fact most formulators come to it for.
Heart is also a high-fat tissue, which shapes how it mills and whether a formula should specify it defatted.
Exact values vary by lot, origin and tier, and by whether the powder is defatted. Every order ships with a certificate of analysis, lab results and a specification sheet. Nutritional analysis is something we assist with rather than supply, because the numbers depend on your finished formulation rather than on the raw lot.
What do formulators use heart powder in?
Mostly in single-organ heart products and in multi-organ blends. Heart is a common partner to bovine liver, bovine kidney and bovine spleen in organ complexes.
Some customers build a formula around the CoQ10 heart naturally contains, positioning it as a whole-food ingredient rather than an isolated one. Others use it in pet nutrition, where the material starts as human-grade food under USDA inspection. It works in capsules, tablets and powder blends.
Claims on the finished product are the brand owner’s to make and substantiate. What we can give you is a clear spec and the documentation behind it.
Why is heart harder to mill than other organs?
Because of the fat. Heart is high in fat and usually requires cryogenic milling to hit a fine mesh spec at all.
Flatiron Food Factory, our sister manufacturer, runs both a hammer mill and a cryogenic mill, with a milling scientist on staff calling which one a lot needs. The hammer mill handles most of the catalog. The cryogenic mill handles very fine mesh, high-density specs and high-fat material like heart.
Density and mesh are set to your formulation, then held batch to batch. Most freeze dryers have no milling capability and send material out to a separate mill, which is where lot-to-lot drift in a fatty powder tends to show up. If a heart powder you bought elsewhere runs inconsistently on your line, milling is the first place to look.
When should a formula specify defatted heart?
When flow, fat content or shelf life matters more than the fat-soluble fraction. Our heart powder is non-defatted by default, and defatted on request.
The trade-off is real. CoQ10 is fat-soluble, so defatting can take some of it out with the fat. A formula built around heart’s natural composition usually wants non-defatted material. A formula where heart is one ingredient in a blend, or where a sticky powder is slowing a filling line, may be better served by a defatted spec.
Our post on defatted vs non-defatted organ powders covers the choice in more detail. If you need a defatted spec, say so on the quote request.
Freeze-dried or desiccated heart?
Freeze-dried is the premium tier; desiccated is the value tier. Your quote says which one it covers, and we tell you plainly which one you are buying.
Freeze-drying removes water from frozen material by sublimation, so the powder avoids the heat of spray-drying or conventional dehydration. Flatiron freeze-dries our flagship material. Desiccated heart is sourced rather than made in house. Technically all powder is dried, but as a category “desiccated” means not freeze-dried.
Where does the heart powder come from?
Our flagship tier is US grass-fed, human-grade raw material under USDA inspection. Flatiron heat treats it at a minimum of 145°F for seven minutes, then freeze-dries and mills it in Loveland, Colorado. There is no high-pressure pasteurization, chemical bath or irradiation.
We also distribute material from New Zealand, Australia, South America and China, all stocked in the United States, and current origin availability for heart comes back with your quote. The New Zealand, Australian and South American material is HPP-processed to those regions’ standards. Material comes in grass-fed, grass-finished, organic and conventional tiers. Origin and tier are separate facts, and we state both for every lot. Our quality and sourcing page covers the options in full.
What should you ask a heart powder supplier?
Ask the questions that decide how the powder will run and what it contains. A supplier who answers them plainly is one you can qualify.
- Origin and tier. Which country, and which of grass-fed, grass-finished, organic or conventional?
- Grade. Is the raw material human-grade under USDA inspection, or FDA pet-downgraded material?
- Kill step. Heat treatment, or high-pressure pasteurization with a chemical bath or irradiation?
- Fat. Non-defatted or defatted, and can they supply both?
- Drying. Freeze-dried or desiccated?
- Milling. Hammer or cryogenic, done in house or sent out, and can they hold your mesh and density batch to batch?
- Documentation. What ships with every order, and what is on request?
- Additives. Any fillers or flow agents? Ours have none.
- Lead time. Is it in stock? In-stock material from us ships in 7 to 10 business days; a custom run is 6 to 8 weeks.
Getting a quote for bovine heart powder
Heart is worth specifying carefully: the fat that makes it distinctive is also what makes it demanding to mill and handle. Get the origin, tier, fat spec and mesh right at the start, and it runs like any other powder on your line.
Request a quote with the volume, mesh or density spec and fat spec you need. Orders start at 10 kg per ingredient, and quotes come back within 12 to 24 hours.
