edible sunflower seeds

Sunflower seeds are edible and have many health benefits. They can be enjoyed as a healthy snack, either raw or baked. The husks of the seeds are edible, but eating too much may cause constipation and stomach upset. It is recommended to spit out the shells or choose shelled or shelled seeds.

Chocolate-covered sunflower seeds are also available and can be eaten in moderation. Popular as party favors or even favors at weddings, these chocolate desserts appeal to many because of their taste and crunch.

Production of sunflower oil

First recognized by Native Americans and later produced in large quantities in Russia, sunflower oil is now a healthier cooking option. It is lower in saturated fat, making it a healthier choice compared to other oils. Sunflower oil can be used for baking, frying, roasting vegetables, and even as a salad dressing base. It's versatile and doesn't overpower the flavor of food like olive oil does. It can replace margarine and high-fat cream in cakes and home baking. Additionally, sunflower oil can be used as a massage oil and DIY beauty preparation due to its light, non-greasy nature. It has no strong smell and is suitable for daily beauty.

livestock feed

Black oil sunflower seeds and shelled or striped sunflower seed varieties are feed options for backyard birds. Black oil seeds are of high quality and attract a variety of bird species. Since the outer shell of the seeds is soft, the kernels are easily accessible. These seeds are a good source of energy during the winter and can be supplemented with ripe fruit. Placing food at different heights will attract different species of birds. Sunflower meats are a bird favorite because they eliminate mess and waste in the yard.

Sunflower natural dye color

The sunflower plant produces natural dyes in yellow, orange, light tan, gray and dark purple. These dyes can be used to dye fabrics and yarns without the need for artificial chemicals.
