Spinach Juice Powder Processing
The botanical entity is Spinacia oleracea L., common spinach, a cool-season leaf crop in the amaranth family (Amaranthaceae). It is not water spinach, Ipomoea aquatica, nor New Zealand spinach, Tetragonia tetragonioides, which are unrelated plants sold under similar names. The part used is the leaf and its petiole, and the fresh leaf is the only raw plant material.
The raw material is spinach juice concentrate. Leaves are washed, macerated and pressed, and the green juice is concentrated by evaporation, blended with maltodextrin and atomized in a spray dryer. The carrier makes the powder flow and disperse, and it dilutes the chlorophyll so that the finished color is lighter than the pressed juice.
Heat and acid during concentration convert some chlorophyll to pheophytin, an olive-brown pigment, so the powder shows an olive-leaning green. Fresh spinach leaves are tender and spoil quickly, and processors press shortly after harvest, since wilting and bruising raise the grassy off-notes in the juice.
Spinach grows best in cool seasons, and spring and autumn crops give the lightest flavor. Summer-grown leaves bolt and turn bitter, so concentrate producers rely on cool-season fruit. The result is described by taste and color, not by cultivar.
Spinach juice is rich in water-soluble pigments and low in fiber, so the powder differs from the whole-leaf form in more than texture. The color is lighter, the flavor is cleaner and less hay-like, and the powder wets and dissolves faster, although it never becomes clear because chloroplast fragments stay dispersed.
