Measuring Oleic Acid Content in Sunflower Grain & Other High Oleic Crops



Sunflower is an oilseed of global presence and importance, with a distinguished place in agriculture and the food industry in general.

High Oleic Sunflower (HOSO) has been on the market as a premium product offering advantages from the Linoleic or regular Sunflower Oil. Here we explore some of the benefits of high oleic sunflowers, that translate to the produced oil. Particularly Spinlock contributes to the measurement of Oleic Acid content on Sunflower grain and Seed, considering implications for human health, food industry and sustainability. Measuring Sunflower quality is critical to identify, separate and correctly commercialize all High Oleic, Mid Oleic (NuSun) and High Linoleic Sunflower.   

The Role of Oleic Acid in Sunflower Oil

Oleic acid is a monounsaturated fatty acid in sunflower oil. It is essential to understand that not all sunflower oils are equivalent. In this case, oleic acid content in sunflower oil significantly affects its properties and applications. A higher oleic acid content is associated with several important attributes:

  • Improved Stability: Sunflower oil with high oleic acid content is more stable, less prone to oxidation, and has a longer shelf life. This characteristic is important for food products, implying increased freshness and contributing to avoid rancidity.
  • Enhanced Health Profile: Oleic acid is a heart-healthy monounsaturated fat that can contribute to better cholesterol profiles. High oleic sunflower oil is often recommended as a healthier alternative to oils high in saturated fats, and also a more accessive alternative than a pure olive oil diet.
  • Versatile Culinary Applications: Sunflower oil with a higher oleic acid content has a neutral flavor and a high smoke point, making it suitable for a wide range of cooking methods, including frying and baking.
  • Industrial and Commercial Use: High oleic sunflower oil is used in various industrial applications, including the production of biodiesel, cosmetics, and as a base for industrial lubricants.

Measuring Oleic Acid Content for Quality Assurance

The commercialization of Oilseeds in general takes into consideration the amount of fat in traded grain, it is one of the most important parameters to determine the price of each truck/ship and therefore kilogram traded. Accurate measurement of oleic acid content in sunflower grain is essential to classify the oilseed, authorize offload, pay the correct price, and also to obtain a crude oil that falls within the intended specifications (including Oleic Acid content).

Adequately measuring the Oleic Acid content together with the Oil/Fat content provides valuable information to farmers, processors, and consumers:

Seed Hybrid Development: Seed companies with a Sunflower seed development program place special attention to improving genetics of the seed. Breeders need to know the oil and oleic acid content to have adequate feedback on the presence of the genetic conditions they are looking to obtain.

Commercial Quality Control in Agriculture: Farmers and Traders can use oleic acid content measurements to select high oleic sunflower varieties, optimize growing conditions, and determine the correct price and product quality conditions.

Food Industry Standards: Food manufacturers and processors rely on oleic acid measurements to meet industry standards and produce products with consistent quality. This is particularly important for products like cooking oils, snacks, and baked goods.

Consumer Awareness: Informed consumers are increasingly seeking healthier and higher-quality food products. Oleic acid content labels on food packaging help consumers make healthier choices and meet their dietary preferences.

Agricultural Sustainability

Measuring oleic acid content also has implications for sustainable agriculture:

Improved Crop Efficiency: Selective breeding and genetic modification techniques can be used to develop sunflower varieties with higher oleic acid content. This can lead to higher yields and reduced input requirements, making agriculture more sustainable.

Crop Diversification: Encouraging the cultivation of high oleic sunflower varieties can promote crop diversification, reducing the risks associated with monoculture farming and enhancing soil health.


Measuring oleic acid content in sunflower grain is of great importance due to its far-reaching implications for human health, the agriculture industry as a whole, the food industry, and agricultural sustainability.

Spinlock has contributed to this industry challenge with its line of Magnetic Resonance Spectrometers, SLK 200 ( and has deployed a great deal of devices around the world for this specific application. As a pioneer on Oleic Acid measurement, Spinlock continues to support Seed Companies, Farmers, Traders and Crushers alike around all 5 continents.
