Apricot Kernel Anatomy

Structure

Anatomy of a Drupe: Skin, Flesh, Stone & Seed

Each layer of the apricot plays a distinct role — only the innermost seed contains amygdalin.

1

Exocarp

Skin

Thin velvety outer layer covering the fruit's surface, rich in protective waxes and pigment.

2

Mesocarp

Flesh / Pulp

Juicy orange tissue that makes up the edible fruit. Contains sugars, carotenoids, and organic acids — roughly 80% of total fruit weight.

3

Endocarp

Stone / Pit

Hard, woody shell that encases and protects the seed. Lignified structure characteristic of all Prunus stone fruits.

4

Seed — Cotyledons

Kernel Amygdalin zone

Where amygdalin is concentrated — the focus of this guide and the raw material sourced for Novodalin® supplements. Inner cotyledons contain the highest levels.

Six Key Facts About the Apricot Kernel

Bitter vs. Sweet

Bitter apricot kernels (var. amara) contain substantially more amygdalin than sweet varieties. TJ Supply sources exclusively from bitter cultivars to ensure maximum potency.

Prunus Genus

Prunus armeniaca belongs to the same genus as peaches, cherries, and plums — all containing amygdalin in their kernels, though at lower concentrations than apricot.

Oil Content

Kernels contain 40–55% fixed oil. Cold-pressing removes the oil fraction before extraction, isolating the glycoside fraction needed for pharmaceutical-grade amygdalin.

Origin Regions

Central Asia (Uzbekistan, Kazakhstan) and the Mediterranean basin produce the preferred bitter apricot cultivars with consistent amygdalin levels suitable for pharmaceutical-grade extraction.

Yield per Fruit

Each apricot yields a single kernel weighing 0.3–0.5 g. Industrial sourcing uses stone-fruit byproduct from food processing — reducing waste while supplying the supplement industry.

TJ Supply Sourcing

Kernels are selected by amygdalin content per lot, verified by certificate of analysis. Each batch is traceable from source to finished Novodalin® product with HPLC-verified purity ≥98%.

Important Safety Note

Raw apricot kernels should be consumed with caution. The European Food Safety Authority (EFSA) advises adults to consume no more than 3 small kernels per day due to cyanide risk; children should avoid them entirely. Amygdalin/Laetrile is not FDA-approved as a cancer treatment.
