Guava Leaf Extract Powder

Guava leaf extract is made from the leaf of Psidium guajava, not from the fruit, bark or seed. Water extraction concentrates the soluble leaf fraction, and the liquor is dried into a green powder that disperses in water.

The extract is supplied at a 10:1 ratio and milled to 80 mesh, with no marker percentage declared. A separate guava leaf extract with a defined polyphenol level and two guava fruit powders are listed, so this guava leaf extract is the plain leaf ratio line.

Psidium guajava Identity & Plant Part

The botanical entity is Psidium guajava L., common guava, a small evergreen tree of the Myrtaceae grown across the tropics. The part used is the leaf, which is leathery, aromatic and strongly veined. Fruit, bark, seed and root are not included. Guava fruit powder and guava leaf extract come from different organs and have little in common beyond the species. The leaf is rich in tannins, flavonol glycosides and phenolic acids, named here as families only, together with a small amount of volatile oil.

Guava Leaf Extract vs Other Forms

Guava Leaf Extract 20% PolyphenolsLeaf extract with a defined polyphenol levelA stated polyphenol level is required

Freeze-Dried Guava PowderFreeze-dried powder made from the guava fruitA freeze-dried fruit powder is wanted

A 10:1 ratio describes concentration relative to the leaf, not content. It says nothing about polyphenol content.

Leaf and fruit are different ingredients with different buyers. The two fruit powders are flavor and color materials, whereas the leaf is a tannin-bearing botanical with an astringent profile. A purchase document that writes guava extract only leaves the organ open, so the leaf must be named. For a defined polyphenol level the marker-based leaf extract is the matching line, and this ratio extract fits when leaf identity matters most.

Application Areas

Leaf Extract Capsules

Guava leaf extract fills capsules as a green powder with a faint tea-like, tannic note. The green color is stable in the capsule, and a flow aid in the premix prevents the fine powder from bridging in the hopper. Natural leaf color holds up better in opaque capsule shells.

Green Tea-Style Instant Mixes

In instant mixes the extract gives a hazy green-brown liquid with a mild astringency that suits lemon, mint and fruit-tea flavors. A carrier such as maltodextrin keeps the small dose even from sachet to sachet. Chilled preparations need more carrier, because the powder wets slowly in cold water.

Tablet Blends with Leaf Extracts

Guava leaf extract can be compressed at moderate inclusion alongside microcrystalline cellulose. The green tint can speckle a white tablet, so a colored film coat or a tinted core is the cleaner choice. Dry granulation is gentler on a leaf extract than wet granulation.

Leaf-Tint Gummy Bases

In gummies the extract gives a greenish-brown tint that works with lime, apple and herbal flavors. Add it late in the cook, because heat dulls the leaf color toward brown. Citric acid in the deposit shifts the tint, so test the shade at the final gummy pH.

Sachet Drink Mixes

Sachets pair the extract with fruit acid and sweetener. Acid shifts the leaf color toward olive, so test the shade of the finished drink and choose opaque film to protect the powder from light. Fill under dry conditions; green leaf extract clumps at the sachet seal once it picks up moisture.

Formulation Notes

Guava leaf extract is a green powder with a faint, tea-like, slightly resinous aroma and a mildly bitter, astringent taste. Wetted with water, it turns into a hazy green-brown liquid. Tannins make the extract astringent, and they bind proteins, so milk-based drinks can turn cloudy.

A leaf water extract takes up moisture from the air, so weigh the guava leaf extract in a dry room and reseal the pack after each draw. Color shifts toward brown with moisture and light. Iron contact can darken tannin solutions, so use stainless or plastic tools, and premix with a free-flowing carrier before filling capsules.

Leaf extracts carry chlorophyll breakdown products that dull toward olive over time, particularly in warm, humid storage. For a stable green shade, keep packs of guava leaf extract sealed, store them away from heat and avoid damp scoops or open bins.
