Quantitative composition of cold-pressed orange oils
Sunflower oil is one of the edible oils best considered in terms of the physiology of nutrients. In addition, sunflower oil is used in the food industry (margarine, salad dressings, mayonnaise). As a result of its heat stability it is also suitable for cooking. Because of its high content of unsaturated fatty acids, it is used as diet oil.

Among new sources of edible oils with high levels of bioactive compounds, cold pressed black cumin oil (BCO) is of interest and may play a role in human health. At different levels of blending SO with BCO, the stability of sunflower oil (SO) was enhanced. The optimal level of BCO enrichment will depend on the actual food application.

Organic Cold Pressed Sunflower Oil is extracted from organic pure sunflower seeds. It is unrefined, unbleached and most importantly, cold pressed. Most conventional sunflower oils in the market are extracted through heat or chemical processes. Cold pressed oils retain antioxidants and phytonutrients that are otherwise damaged when exposed to heat.

In addition, although oil yield from the cold-press process is low, the by-product is a sunflower oilcake with high oil content and no added chemicals, which VPO sells to livestock owners and feed manufacturers. According to Homsek, HO sunflower oil has almost the same fatty acid composition, and therefore health benefits, as olive oil.

The oil yield of the cold-pressing technique is lower than hot-pressing, solvent, and supercritical carbon dioxide (CO 2) extraction (8). In recent years, interest and demand of consumers to use cold-pressed oil have increased because cold-pressed oils are natural, nutritional, and safe food products (9, 10).

Plant oils are a good source of compounds that decrease the risk of some diseases. Growing consumer awareness has led to more interest in natural cold-pressed plant oils, which are often considered functional foods. Many unconventional edible plant oils are available on the market, but their quality and composition are often unknown. The aim of this study was to compare the nutritional value

ABSTRACT. This study examines the extraction of oil from cold-press rapeseed cake using Supercritical CO 2 (SC-CO 2).The effects of pressure (20, 30, and 40 MPa), temperature (40, 50, and 60 潞C), and extraction time (60, 90, and 120 min) on oil yield and composition (tocopherols and carotenoids) were studied using response surface design.
