A pumpkin seed, also known in North America as a pepita (from the Mexican Spanish : pepita de calabaza, 'little seed of squash'), is the edible seed of a pumpkin or certain other cultivars of squash. The seeds are typically flat and oval with one axis of symmetry, have a white outer husk, and are light green in color after the husk is removed. Some pumpkin cultivars are huskless, and are grown only for their edible seed. [1] The seeds are nutrient- and calorie-rich, with an especially high content of fat (particularly linoleic acid and oleic acid), protein, dietary fiber, and numerous micronutrients. Pumpkin seed can refer either to the hulled kernel or unhulled whole seed, and most commonly refers to the roasted end product used as a snack.

Unhulled vs. hulled pumpkin seeds

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 in the US by their Spanish name (usually shortened), and typically salted and sometimes spiced after roasting. They are also available as a packaged product in Mexico and other Latin American countries, in the American Southwest, and in specialty 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, followed by beans, all becoming part of the Three Sisters agricultural system. [5] [6]

Hulled pumpkin seeds

As an ingredient in mole dishes, they are known in Mexican Spanish as pipián. A salsa made of pumpkin seeds and known as sikil pak is a traditional dish of the Yucatán. [7] [8] A Mexican snack using pepitas in an artisan fashion[ clarification needed ] is referred to as pepitoría. Lightly roasted, salted, unhulled pumpkin seeds are popular in Greece with the descriptive name πασατέμπο, pasatémbo, from Italian : passatempo, lit. 'pastime'.

The pressed oil of the roasted seeds of a Cucurbita pepo subsp. pepo var. 'styriaca' is also used in Central and Eastern Europe cuisine. [9] [10] Pumpkin seeds can also be made into a nut butter. Pumpkin seeds can also be steeped in neutral alcohol, which is then distilled to produce an eau de vie . [11]

Dried, roasted pumpkin seeds are 2% water, 49% fat, 15% carbohydrates, and 30% protein (table). In a 100-gram reference serving, the seeds are energy-dense (2,401 kJ or 574 kcal), and a rich source (20% of the Daily Value, DV, or higher) of protein, dietary fiber, niacin, iron, zinc, manganese, magnesium, and phosphorus (table). [14] The seeds are a moderate source (10–19% DV) of riboflavin, folate, pantothenic acid, sodium, and potassium (table). Major fatty acids in pumpkin seeds are linoleic acid and oleic acid, with palmitic acid and stearic acid in lesser amounts. [14]

Oil

Pumpkin seed oil, 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: [15]

n:unsatFatty acid namePercentage 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. [15] 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. [15]

Traditional medicine

Pumpkin seeds were once used as an anthelmintic in traditional medicine to expel tapeworms parasites, such as Taenia tapeworms. [16] This led to the seeds being listed in the United States Pharmacopoeia as an antiparasitic from 1863 until 1936. [17]

Market

Due to their versatility as a food product ingredient or snack, pumpkin seeds are projected to grow in sales by 13% annually and reach $631 million from 2020 to 2024. [18]

<span class="mw-page-title-main">Eastern Agricultural Complex</span> Agricultural practices of pre-historic native cultures in the eastern United States and Canada

The Eastern Agricultural Complex in the woodlands of eastern North America was one of about 10 independent centers of plant domestication in the pre-historic world. Incipient agriculture dates back to about 5300 BCE. By about 1800 BCE the Native Americans of the woodlands were cultivating several species of food plants, thus beginning a transition from a hunter-gatherer economy to agriculture. After 200 BCE when maize from Mexico was introduced to the Eastern Woodlands, the Native Americans of the eastern United States and adjacent Canada slowly changed from growing local indigenous plants to a maize-based agricultural economy. The cultivation of local indigenous plants other than squash and sunflower declined and was eventually abandoned. The formerly domesticated plants returned to their wild forms.

<span class="mw-page-title-main">Crookneck squash</span> Cultivar of Cucurbita pepo

Crookneck squash, also known as yellow squash, is a cultivar of Cucurbita pepo, the species that also includes some pumpkins and most other summer squashes. The plants are bushy and do not spread like the plants of winter squash and pumpkin. Most often used as a summer squash, it is characterized by its yellow skin and sweet yellow flesh, as well as its distinctive curved stem-end or "crooked neck". It should not be confused with crookneck cultivars of Cucurbita moschata, such as the winter squash 'Golden Cushaw', or the vining summer squash 'Tromboncino'. Its name distinguishes it from another similar-looking variety of C. pepo, the straightneck squash, which is also usually yellow. There is one similar non-edible C. pepo variety: C. pepo var. ovifera.

It is a cultivar of the species Cucurbita pepo, which also includes the summer squash varieties pattypan squash, zucchini, and yellow crookneck squash, as well as winter squash varieties including acorn squash, spaghetti squash, and most pumpkins used as Jack-o-lanterns.

<span class="mw-page-title-main">Winter squash</span> Squash harvested and eaten in mature stage; skin hardened into tough rind

Winter squash is an annual fruit representing several squash species within the genus Cucurbita. Late-growing, less symmetrical, odd-shaped, rough or warty varieties, small to medium in size, but with long-keeping qualities and hard rinds, are usually called winter squash. They differ from summer squash in that they are harvested and eaten in the mature stage when their seeds within have matured fully and their skin has hardened into a tough rind. At this stage, most varieties of this vegetable can be stored for use during the winter. Winter squash is generally cooked before being eaten, and the skin or rind is not usually eaten as it is with summer squash.
