Frozen chopped spinach is the standard industrial ingredient for spanakopita (Greek spinach and feta pie) production. The process: thaw frozen chopped spinach, squeeze out excess moisture (important for pastry crispiness), combine with crumbled feta, eggs, onion, dill, and seasoning, fill filo pastry, and bake. The fine-chop format distributes evenly through the filling, the high moisture content (when not squeezed) acts as a natural binder, and the deep green colour provides the visual contrast that defines authentic spanakopita filling appearance.

Spinach contains non-heme iron (plant-based) rather than heme iron (animal-based). Non-heme iron has lower bioavailability than heme iron — typically 2–20% absorption versus 15–35% for heme iron. However, bioavailability of spinach iron is significantly enhanced by consuming it with Vitamin C: citrus juice, tomato sauce, or other Vitamin C sources increase non-heme iron absorption up to 3× when consumed simultaneously. For food manufacturers developing iron-supplemented products, IBIC frozen spinach (6.4mg iron per 180g cooked serving, 29% DV) combined with a Vitamin C source provides effective plant-iron delivery in a clean-label formulation.
