When selecting sunflower seeds, the following factors can be considered:
1. Observe appearance: The color of sunflower seeds should be essential, such as a gray shell mixed with white stripes, bright and glossy. The shell shape should be full and the particles should be uniform. The white melon seeds are light yellow in color, while the black melon seeds are black or dark brown in color, but the edges should be light yellow. If the melon seeds are completely black, it may be stained melon seeds
2. Feeling texture: When touching sunflower seeds, it should feel dry and not sticky to the hands. Gently pinch the melon seeds to feel full and firm. If you feel weak or damp, the quality may be poor. In addition, place the melon seeds on a flat plate at a 45 degree angle. If the seeds slide off, it may be due to the addition of talcum powder
3. Check the seed kernel: The seed kernel should be thick, crispy, evenly sized, and white in color. If the seed kernel is white and withered, or the center is red, and the flesh is yellow and ripe, the quality may be poor or have deteriorated
4. Smell the scent: Good sunflower seeds should have a natural fragrance that is comfortable to smell
5. Testing the degree of dryness and wetness: Dry melon seeds are prone to cracking when bitten with teeth, and the sound is crisp. The sound of the melon seeds falling to the ground is solid and loud. However, damp melon seeds are less prone to cracking when eaten, and their sound may be light or silent. Grab a handful of melon seeds and let them go. If there is a clattering sound, it indicates that the seeds are dry; If the sound is muffled, it indicates that the melon seeds may absorb water and become damp
6. Check for insect holes: When selecting loose melon seeds, carefully check and choose seeds with fewer insect holes
In summary, when selecting sunflower seeds, factors such as appearance, texture, kernel, odor, dryness and wetness, and the presence of insect holes should be comprehensively considered to ensure the purchase of high-quality sunflower seeds
