A pumpkin seed, also known 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 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.
Pumpkin seeds are a common ingredient in Mexican cuisine and are also roasted and served as a snack. [2] They are 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 are typically salted and sometimes spiced after roasting.
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 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]
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 the Styrian oil pumpkin ( 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). 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 (source in table).
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: [14]
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. [14] 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. [14]
Pumpkin seeds were once used as an anthelmintic in traditional medicine to expel tapeworms parasites, such as Taenia tapeworms. [15] This led to the seeds being listed in the United States Pharmacopoeia as an antiparasitic from 1863 until 1936. [16]
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. [17]
A sunflower seed is a seed from a sunflower. There are three types of commonly used sunflower seeds: linoleic, high oleic, and sunflower oil seeds. Each variety has its own unique levels of monounsaturated, saturated, and polyunsaturated fats. The information in this article refers mainly to the linoleic variety.
Cucurbita is a genus of herbaceous fruits in the gourd family, Cucurbitaceae, native to the Andes and Mesoamerica. Five edible species are grown and consumed for their flesh and seeds. They are variously known as squash, pumpkin, or gourd, depending on species, variety, and local parlance. Other kinds of gourd, also called bottle-gourds, are native to Africa and belong to the genus Lagenaria, which is in the same family and subfamily as Cucurbita, but in a different tribe, their young fruits are eaten much like those of the Cucurbita species.
Spaghetti squash or vegetable spaghetti is a group of cultivars of Cucurbita pepo subsp. pepo. They are available in a variety of shapes, sizes, and colours, including ivory, yellow and orange, with orange having the highest amount of carotene. Its center contains many large seeds. When raw, the flesh is solid and similar to other raw squash. When cooked, the meat of the fruit falls away from the flesh in ribbons or strands that look like and can be used as an alternative to spaghetti.
Cucurbita pepo is a cultivated plant of the genus Cucurbita. It yields varieties of winter squash and pumpkin, but the most widespread varieties belong to the subspecies Cucurbita pepo subsp. pepo, called summer squash.
Salvia hispanica, one of several related species commonly known as chia, is a species of flowering plant in the mint family, Lamiaceae, native to central and southern Mexico and Guatemala. It is considered a pseudocereal, cultivated for its edible, hydrophilic chia seed, grown and commonly used as food in several countries of western South America, western Mexico, and the southwestern United States.
Kabocha is a type of winter squash, a Japanese variety of the species Cucurbita maxima. It is also called kabocha squash or Japanese pumpkin in North America. In Japan, "kabocha" may refer to either this squash, to the Western pumpkin, or indeed to other squashes. In Australia, "Japanese pumpkin" is a synonym of Kent pumpkin, a variety of winter squash.
Pumpkin seed oil is a culinary oil, used especially in eastern Europe.
Cucurbita ficifolia is a species of squash, grown for its edible seeds, fruit, and greens. It has common names including black seed squash, chilacayote, cidra, fig-leaf gourd, and Malabar gourd. Compared to other domesticated species in its genus, investigators have noted that samples of C. ficifolia from throughout its range are relatively similar to one other in morphology and genetic composition. Variations do occur in fruit and seed color, some isozymes, and photoperiod sensitivity.
Butternut squash, known in Australia and New Zealand as butternut pumpkin or gramma, is a type of winter squash that grows on a vine. It has a sweet, nutty taste similar to that of a pumpkin. It has tan-yellow skin and orange fleshy pulp with a compartment of seeds in the blossom end. When ripening, the flesh turns increasingly deep orange due to its rich content of beta-carotene, a provitamin A compound.
Chia seeds are the edible seeds of Salvia hispanica, a flowering plant in the mint family (Lamiaceae) native to central and southern Mexico, or of the related Salvia columbariae, Salvia polystachia, or Salvia tiliifolia. Chia seeds are oval and gray with black and white spots, having a diameter of around 2 millimetres (0.08 in). The seeds are hygroscopic, absorbing up to 12 times their weight in liquid when soaked and developing a mucilaginous coating that gives chia-based foods and beverages a distinctive gel texture.
Sunflower oil is the non-volatile oil pressed from the seeds of the sunflower. Sunflower oil is commonly used in food as a frying oil, and in cosmetic formulations as an emollient.
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.
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.
Delicata squash is a variety of winter squash with cylindrical fruits that are cream-coloured and striped in green or orange. As its name suggests, it has characteristically a delicate rind. It is also known as peanut squash, Bohemian squash, or sweet potato squash. It is a very sweet variety with a thin, edible skin and is typically cut into half rounds and roasted. 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.
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.
Cucurbita maxima, one of at least five species of cultivated squash, is one of the most diverse domesticated species. This species originated in South America from the wild subspecies Cucurbita maxima subsp. andreana over 4,000 years ago. Cucurbita maxima, known for modern varieties as Hubbard, Delicious, Marblehead, Boston Marrow, and Turks Turban, originated in northern Argentina near the Andes or in certain Andean valleys. Secondary centers of diversity include India, Bangladesh, Myanmar, and the southern Appalachians.
A pumpkin is a cultivated winter squash in the genus Cucurbita. The term is most commonly applied to round, orange-colored squash varieties, but does not possess a scientific definition. It may be used in reference to many different squashes of varied appearance and belonging to multiple species in the Cucurbita genus.
Red kuri squash is a thin skinned orange colored winter squash, a cultivated variety of the species Cucurbita maxima. It looks like a small pumpkin without the ridges. It belongs to the Hubbard squash group.
Cucurbita argyrosperma, also called the cushaw squash and silver-seed gourd, is a species of winter squash originally from the south of Mexico. This annual herbaceous plant is cultivated in the Americas for its nutritional value: its flowers, shoots, and fruits are all harvested, but it is cultivated most of all for its seeds, which are used for sauces. It was formerly known as Cucurbita mixta.
The Styrian oil pumpkin, also known as the Styrian pumpkin, is a variety of the common pumpkin which is cultivated to produce pumpkin seed oil.
