Pepita
Pepita (from Mexican Spanish: pepita de calabaza, "little seed of squash") is a Spanish culinary term for the pumpkin seed, the edible seed of a pumpkin or other cultivar of squash (genus Cucurbita). The seeds are typically rather flat and asymmetrically oval, and light green in color and may have a white outer hull. Some cultivars are hulless, and are grown only for their seed.[1] The seeds are nutrient-rich, with especially high content of protein, dietary fiber and numerous micronutrients. The word can refer either to the hulled kernel or unhulled whole seed, and most commonly refers to the roasted end product.
Cuisine
Pumpkin seeds are a common ingredient in Mexican cuisine and are also roasted and served as a snack.[2] Marinated and roasted, they are an autumn seasonal snack in the United States, as well as a commercially produced and distributed packaged snack, like sunflower seeds, available year-round. Pepitas are known by their Spanish name (usually shortened), and typically salted and sometimes spiced after roasting (and today also available as a packaged product), in Mexico and other Latin American countries, in the American Southwest, and in speciality and Mexican food stores.
The earliest known evidence of the domestication of Cucurbita dates back 8,000–10,000 years ago, predating the domestication of other crops such as maize and common beans in the region by about 4,000 years. Changes in fruit shape and color indicate intentional breeding of C. pepo occurred by no later than 8,000 years ago.[3][4] The process to develop the agricultural knowledge of crop domestication took place over 5,000–6,500 years in Mesoamerica. Squash was domesticated first, with maize second and then beans being domesticated, becoming part of the Three Sisters agricultural system.[5][6]
As an ingredient in mole dishes, they are known in Spanish as pipián. A Mexican snack using pepitas in an artisan fashion is referred to as pepitoría. Lightly roasted, salted, unhulled pumpkin seeds are popular in Greece with the descriptive Italian name, passatempo ("pastime").
The pressed oil of the roasted seeds of a Cucurbita pepo subsp. pepo var. 'styriaca' is also used in Central and Eastern Europe as cuisine, such as Pumpkin seed oil.[7][8]

In a 100 gram serving, the seeds are calorie-dense (574 kcal) and an excellent source (20% of the Daily Value, DV, and higher) of protein, dietary fiber, niacin, iron, zinc, manganese, magnesium and phosphorus (table).[9] The seeds are a good source (10–19% DV) of riboflavin, folate, pantothenic acid, sodium and potassium (table).
Oil
The oil of pumpkin seeds, a culinary specialty in and important export commodity of Central Europe, is used in cuisine as a salad and cooking oil.
The following are ranges of fatty acid content in C. maxima pepitas[10] (see pumpkin seed oil):
| n:unsat | Fatty acid name | Percentage range |
|---|---|---|
| (14:0) | Myristic acid | 0.003–0.056 |
| (16:0) | Palmitic acid | 1.6–8.0 |
| (16:1) | Palmitoleic acid | 0.02–0.10 |
| (18:0) | Stearic acid | 0.81–3.21 |
| (18:1) | Oleic acid | 3.4–19.4 |
| (18:2) | Linoleic acid | 5.1–20.4 |
| (18:3) | Linolenic acid | 0.06–0.22 |
| (20:0) | Arachidic acid | 0.06–0.21 |
| (20:1) | Gadoleic acid | 0–0.035 |
| (22:0) | Behenic acid | 0.02–0.12 |
The total unsaturated fatty acid concentration ranged from 9% to 21% of the pepita.[10] The total fat content ranged from 11% to 52%. Based on the quantity of alpha-tocopherol extracted in the oil, the vitamin E content of twelve C. maxima cultivar seeds ranged from 4 to 19 mg/100 g of pepita.[10]
