Mid oleic sunflower

Breeding a mid-oleic sunflower requires at least one oleic parent. The USDA/ ARS Northern Crop Science Laboratory in Fargo, North Dakota, provided private companies with crossing lines of mid-oleic sunflower. Hybrid seeds were developed by traditional crossing methods no hybrids of transgenic sunflower were used. The mid-oleic concentration appears to be controlled by a partially dominant major gene and one or more dominant minor modifier genes (46, 47). 

Table 15 shows the sterol composition of mid-oleic sunflower oil according to the Proposed Draft Amendments to the Standard for Named Vegetable Oils (Report of the Eighteenth Session of the Codex Committee on Fats and Oils, London, 2003). Clearly, p-sitosterol is the sterol with the highest occurrence (56-58% of total sterols), followed by campesterol (9.1-9.6%) and stigmasterol (9.0-9.3%). p-sitosterol is the main sterol in aU three types of sunflower oil (regular, mid-oleic, and high-oleic).

Mid-Oleic Sunflower Oil With the relatively recent appearance of mid-oleic sunflower oil, researchers have shown an interest in its use in frying processes. Abidi and Warner (120) used the three types of sunflower oil (regular, high, and mid-oleic) in the preparation of french fries, potato crisps, and fresh white corn tortilla chips. However, no general conclusions may be drawn regarding inherent stability as there is no indication of antioxidant type and concentration in the different oils. 

Pan-frying is a popular frying method at home and in many restaurants. The panfry stabilities of two oils with similar iodine values—mid-oleic sunflower oil (NuSun) and a commercial canola oil—were compared (121). Both oils have similar pan-fry stabihties, with few significant differences in the physicochemical properties during the heating process.

K. Warner, B. Vick, L. Kleingartner, R. Issak, and K. Doroff, Compositions of Sunflower, NuSun (Mid-Oleic Sunflower) and High-Oleic Sunflower Oils, presented to the 18th session of the Codex Committee Fats and Oils, Feburary, 2003. 

The author is developing (mid-2004) zero trans-, no hydrogenation, no interesterification, no modification of any kind, tub and stick margarines. The formula will include specially processed soybean oil, corn oil, cottonseed oil, or mid-oleic sunflower seed oil, and double-fractionated palm oil, or double-fractionated cottonseed oil. The products are proprietary for now. 

The most logical zero frawi-frying fats are the naturally stable oils, such as cottonseed oil, corn oil, peanut oil, and mid-oleic sunflower seed oil. The use of these oils increased dramatically in 2003 and early 2004 for this purpose. Already in limited supply, this heavy demand will dramatically increase the price of these oils.

An interesting new oil is a mid-oleic sunflower oil known as NuSun . This contains 7-9% saturated acids, 50-75% oleic acid, 20-30% linoleic acid, and <1% a-linolenic acid. In its level of oleic acid, it falls between those of commodity sunflower oil (-20%) and high-oleic varieties (-70-90%). This non-genetically modified material was developed in the USA and was grown on 40 000 hectares in 1998, producing 20 000-25 000 tormes of oil. The...
