Nutruoil®Grape seed oil Health Benefits:

Grape (Vitis vinifera L.), belonging to the Vitaceae family, is a perennial vine commonly known as grape or common grapevine. It is a traditional plant used for both culinary and medicinal purposes. Grape seeds are emerging as a valuable resource for functional foods and medicines owing to their rich oil and polyphenol content with diverse nutritional and health benefits. Grape seed oil constitutes approximately 10% to 20% of the grape seed content.

Nutruoil®Grape seed oil is produced from the seeds of Chinese grapes (Vitis vinifera L.) using a cold-pressing process and is available in refined grades.

Grape, a traditional fruit crop, has been widely cultivated worldwide for winemaking and consumption. Grape seeds are a major by-product of the wine and juice industry and are widely used to extract grape seed oil, which has a mild, neutral aroma and flavour. There are well-established cultivation and winemaking regions in China, such as Xinjiang, Ningxia, and Shandong, and the linoleic acid content and polyphenol richness of grape seed oil from the Xinjiang region are generally high due to abundant sunlight and large temperature differences.

Nutruoil®Grape seed oil is a high linoleic acid and natural antioxidant content product from China, utilising core technology to preserve the high activity of vitamin E and proanthocyanidins during the extraction process.

Nutruoil®Grape seed oil Applications:

The applications of Nutruoil®Grape seed oil are primarily based on its high smoke point, high content of linoleic acid and vitamin E, light texture, and good biocompatibility; it has established applications in the food, cosmetics and pharmaceutical sectors.

The use of Nutruoil®Grape seed oil in food is primarily based on its role as a high-quality cooking oil, but it is also expanding into the realm of more sophisticated functional ingredients. Refined grape seed oil has a high smoke point, making it well-suited for high-temperature cooking methods such as frying and stir-frying, and it is less likely to produce harmful substances. With its neutral and mild flavor, it is often used as a base oil for salad dressings and marinades, or drizzled directly over dishes to enhance their flavor without overpowering the natural taste of the ingredients. Because it is rich in unsaturated fatty acids, phytosterols, and vitamin E, grape seed oil is considered a functional oil with health benefits. It can be added directly or in emulsion form to foods such as meat products, dairy beverages, and chocolate.

In the cosmetics industry, Nutruoil®Grape seed oil is not only an excellent carrier oil, but its skin-care benefits have also been widely proven. In aromatherapy and massage, it serves as an ideal carrier oil for diluting and delivering essential oils.

Traditionally, Nutruoil®Grape seed oil has been used as a wound-healing agent and an anti-inflammatory. In modern nutrition, it has garnered attention for its potential to lower blood lipid levels. In the pharmaceutical field, grape seed oil is often used to manufacture drug delivery systems such as microemulsions and nanoemulsions. Additionally, the active compounds it contains are believed to possess potential pharmacological activities, including cardioprotective and anticancer effects.

The polyphenols (e.g., gallic acid, catechins, procyanidins) and vitamin E in Nutruoil®Grape seed oil act as potent natural antioxidants, helping to scavenge free radicals, alleviate oxidative stress, and inhibit cellular pathways linked to chronic inflammation. 

The cardiovascular benefits of Nutruoil®Grape seed oil are primarily linked to its lipid-lowering and anti-atherosclerotic effects. Studies indicate it helps reduce total lipid levels and lower low-density lipoprotein cholesterol (LDL-C, "bad cholesterol"). Its polyphenols also inhibit LDL oxidation, thereby reducing the risk of atherosclerosis. 

▶ Promotes Skin Health & Wound Healing

Nutruoil®Grape seed oil is widely used for skin health. Its high content of linoleic acid provides regenerating and restructuring properties, helping to maintain the skin barrier. Furthermore, research confirms that GSO (whether applied topically or ingested) demonstrates wound-healing activity and diminishes scars in both animals and humans, making it a valuable ingredient in the cosmetics industry.

■ Fatty acid composition

Nutruoil®Grape seed oil is a high quality, light-tasting cooking oil with a very high linoleic acid content. The fatty acid composition of grape seed oil is relatively simple, with polyunsaturated fatty acids (PUFAs) making up 60.0% to 75.0% of the total, including palmitic acid (5.5-11.0%), stearic acid (2.0-6.5%), oleic acid (11.0-28.0%), linoleic acid (58.0-78.0%) and α-linolenic acid (<1.0%). This oil ranks among the highest in linoleic acid (Omega-6) content compared to other plant seed oils.

Ingredients:

● 100% Grape seed oil, without any additives and preservative as well as antioxidants.

☑ Nutruoil®Grape seed oil, cold pressed & refined, 100% organic

▶ Antimicrobial Activity

Nutruoil®Grape seed oil has shown antimicrobial activity against certain pathogens, including Staphylococcus aureus and Escherichia coli. The mechanism may involve oxidative damage to bacterial plasma membranes by phenolic compounds (particularly resveratrol), suggesting its potential as an adjunct in antimicrobial therapies.
