Nutruoil®Pumpkin seed oil Health Benefits:

Nutruoil®Pumpkin seed oil is a high-quality, functional vegetable oil produced from pumpkin seed kernels using cold-pressing or low-temperature refining processes that comply with national food safety standards. Unlike industrial-grade pumpkin seed oil, which is solvent-extracted and refined to lower standards, it combines natural nutritional value with suitability for food processing. It is a popular ingredient in functional foods, dietary supplements and premium edible oils, and can also be consumed directly.

The quality of Nutruoil®Pumpkin seed oil depends on selecting the right raw materials and using standardised processing techniques. All stages, from cultivation to the finished product, must comply with food-grade standards. Richtek's core raw material is the kernel of a specialised, seed-producing pumpkin variety, rather than ordinary edible pumpkins. These varieties are specifically bred for their plump kernels, high oil content and rich concentration of bioactive compounds. These varieties can have an oil content of 25-35%, which far exceeds that of ordinary edible pumpkins (5-10%), and they contain higher levels of functional components, such as phytosterols and zinc. Pumpkin seeds thrive in cool, dry climates and are well-suited to sandy soils. The main production areas offer advantages in terms of low pesticide residues and high yields, and they are also the primary sources of food-grade raw materials. The main production areas are Inner Mongolia, Xinjiang and Heilongjiang. Inner Mongolia is the country’s largest seed pumpkin cultivation base, where raw materials are free from severe pollution and pesticide residues are strictly controlled.

Nutruoil®Pumpkin seed oil Applications:

Thanks to its strong nutritional properties, mild flavour, high formulation compatibility and adaptability to various applications through processes such as cold pressing, refining and microencapsulation, Nutruoil®Pumpkin seed oil has become a popular ingredient in the food and dietary supplement sectors. Its use is also gradually expanding into areas such as personal care and pet food. Its main uses are to preserve active ingredients (cold pressing/microencapsulation), enhance stability (refining/antioxidant encapsulation) and adapt to different product forms (lipophilic to hydrophilic/solidification). However, there are significant differences in formulation design, process selection and application methods across different sectors.

In the food sector, Nutruoil®Pumpkin seed oil is used as a raw material in the form of food-grade cold-pressed or refined pumpkin seed oil. It is ideally suited to low-temperature consumption and use as a formulation additive, preventing the destruction of active ingredients by high temperatures. At the same time, its subtle, natural pumpkin seed aroma and lack of off-flavours ensure that it does not mask the inherent flavours of the ingredients. It is widely used in sectors such as ready-to-eat products for the mainstream household market, baking and confectionery for industrial processing, and dairy and meal replacement products for functional food processing.

Nutruoil®Pumpkin seed oil is a staple ingredient in dietary supplements designed to support prostate health and regulate blood lipids. Based on highly active, cold-pressed pumpkin seed oil, these products utilise innovative formulations to address issues such as fat solubility, susceptibility to oxidation, and the inconvenience of consumption. This caters for diverse consumer groups, such as the middle-aged and elderly, office workers, and vegetarians. This represents a core segment of the commercial application of pumpkin seed oil. Soft capsules currently dominate the market with a share of over 70%. Bottled oral oil dietary supplements differ from food-grade products. Microencapsulated powders and solid beverages are innovative formulations for solid supplements, with pumpkin seed oil blended into solid beverages combined with probiotics, dietary fibre and zinc. Gummy sweets containing pumpkin seed oil are available in original and fruit flavours (strawberry and orange) and are suitable for children and adolescents.

In addition to its use in food and dietary supplements, Nutruoil®Pumpkin seed oil is gradually finding applications in the personal care and pet food sectors thanks to its fat-soluble active ingredients, such as γ-tocopherol and unsaturated fatty acids, as well as its moisturising and antioxidant properties. It is also used in areas such as animal feed and pharmaceutical excipients, where its natural origin and functional properties are leveraged to replace chemical ingredients.

The most widely recognised health benefits of Nutruoil®Pumpkin seed oil are supporting cardiovascular health and regulating blood lipid and vascular health levels. This is primarily achieved through the synergistic action of phytosterols and unsaturated fatty acids. Pumpkin seed oil contains between 0.3% and 0.8% phytosterols. These compounds compete with cholesterol for absorption sites in the gut, thereby inhibiting the absorption of both dietary and endogenous cholesterol and lowering blood levels of low-density lipoprotein (LDL) without affecting high-density lipoprotein (HDL). This reduces the core risk of atherosclerosis. Unsaturated fatty acids account for at least 70% of the total fatty acid composition of pumpkin seed oil. Linoleic acid (ω-6, 50-60%) and α-linolenic acid (ω-3, 5-10%) are both essential fatty acids for the human body, with a ratio of approximately 6:1, which aligns with the optimal ratio for human fatty acid intake. Linoleic acid is metabolised in the liver into arachidonic acid, which is involved in synthesising vasodilators (prostaglandins) and improving vascular endothelial elasticity. α-Linolenic acid, meanwhile, is metabolised into EPA/DHA, which helps lower triglyceride levels and reduce lipid deposits in blood vessels. Together, they work synergistically to maintain the balance of lipid metabolism.

Nutruoil®Pumpkin seed oil is one of the few vegetable oils that supports reproductive health. This is primarily achieved through its combination of cucurbitacin, zinc, and phytosterols. A common ingredient in dietary supplements for prostate health, it also plays a positive role in regulating the female endocrine system. The unique active compounds in pumpkin seeds can inhibit the activity of 5α-reductase, thereby reducing testosterone conversion to dihydrotestosterone (DHT) in the body. Pumpkin seed oil contains approximately 1.2-2.0 mg of zinc per 100 ml in a readily absorbable, fat-soluble form. Zinc is a key trace element in prostate tissue, participating in the synthesis of prostatic fluid and maintaining the prostate’s normal physiological functions. Furthermore, zinc enhances sperm motility and quality, thereby improving male reproductive health.

▶ Antioxidant

Nutruoil®Pumpkin seed oil contains three main antioxidants: γ-tocopherol, phytosterols and unsaturated fatty acids. These three components work together to remove free radicals from the body, reducing the damage caused by oxidative stress to cells and thereby boosting the immune system. γ-Tocopherol is a fat-soluble antioxidant that penetrates deep into the lipid layers of cells to scavenge free radicals on the cell membrane. This protects the integrity of cellular structures and prevents cellular ageing or damage. Phytosterols help to regulate blood lipids and possess antioxidant properties. They inhibit lipid peroxidation within the body, reduce the production of reactive oxygen species (ROS) and lessen the immune system suppression caused by oxidative stress. Essential fatty acids are key components of immune cell membranes (such as those of lymphocytes and macrophages). Taking pumpkin seed oil as a supplement helps to maintain the normal structure and function of immune cells, enhancing their phagocytic capacity and antibody synthesis and thereby strengthening the body’s resistance to pathogens.Cardiovascular health

▶ Metabolic health

The high-quality fats in Nutruoil®Pumpkin seed oil increase feelings of fullness, regulate fat metabolism and have a positive effect on insulin sensitivity. It is suitable for moderate consumption by people trying to manage their weight and those with impaired glucose tolerance. As fat-soluble components are digested and absorbed more slowly in the gastrointestinal tract, they prolong gastric emptying time, increase satiety and reduce calorie intake during main meals and snacks. Furthermore, as pumpkin seed oil is cholesterol-free and its unsaturated fatty acids are unlikely to be converted into stored fat within the body, replacing some saturated fat intake (such as from animal fats and palm oil) with pumpkin seed oil can help reduce fat accumulation. Linoleic acid and α-linolenic acid improve insulin receptor activity on cell membranes, promote insulin binding to these receptors, enhance glucose uptake and utilisation by cells, and reduce insulin resistance risk.

■ Absorption and metabolism

Nutruoil®Pumpkin seed oil has a nutritional profile centred on unsaturated fatty acids, supplemented by fat-soluble bioactive compounds. Its molecular structure is highly compatible with the human digestive and absorption systems, and it is not accumulated during metabolism. This makes it highly safe for long-term consumption as a food-grade ingredient. The main components of pumpkin seed oil are fatty acids in the form of triglycerides, with unsaturated fatty acids accounting for over 70% of the total. These fatty acids have short carbon chains and low melting points (the melting point of cold-pressed pumpkin seed oil is approximately -10°C), which is significantly lower than that of animal fats and vegetable oils high in saturated fatty acids. This results in a markedly higher efficiency of digestion and absorption. The metabolism of all the nutrients in pumpkin seed oil follows normal human metabolic patterns. The liver is the primary metabolic organ and metabolic by-products are mainly excreted in urine and faeces, with no significant accumulation in the body.
