Dehydrated onion products come in a diverse array of forms, each offering unique qualities and applications in culinary and industrial settings. Among the primary classifications are dehydrated onion flakes, slices, granules, and powder. Onion flakes, characterized by their larger size and irregular shapes, retain a texture and visual appeal ideal for adding texture and bursts of flavor to dishes. Slices, typically larger and more uniform in shape than flakes, offer versatility in applications where a milder onion taste or distinct visual presence is desired. Onion Granules, with their smaller, uniform particles, provide a balance between texture and easy dispersal, making them convenient for seasoning blends and mixes. Meanwhile, Onion Powder, finely ground and highly versatile, serves as a concentrated flavoring agent, seamlessly incorporating into sauces, seasonings, and marinades. Each classification caters to specific culinary needs, allowing for precise flavor control, texture enhancement, and ease of use. The varying particle sizes and forms enable chefs, manufacturers, and consumers to select the most suitable variant for a wide range of culinary creations and industrial applications.

Lettuce seeds pay attention
Lettuce is a crop that thrives under high-temperature conditions, and it generally does not require cold exposure during vernalization. Its flowering period is not strictly dependent on long daylight hours, allowing it to bloom in both spring/summer and autumn. This makes it well-suited for self-seeding, which is why many vegetable farmers choose to save their own seeds. However, successful seed retention requires careful selection of high-quality conventional varieties and proper techniques.
First, the choice of planting area is crucial. Farmers often select healthy lettuce plants for seed saving, but they must ensure the site is sheltered from strong winds, heavy rain, and excessive humidity, as these factors can reduce yield and quality. The selected area should be well-drained and not overly fertile, as overly rich soil may lead to excessive vegetative growth rather than seed production. Although lettuce is primarily self-pollinated, it has an outcrossing rate of about 1%, so isolation from other lettuce varieties is essential. Natural isolation should be at least 100–300 meters, or alternatively, time isolation by staggering flowering periods by more than 30 days.
Second, selecting the best individual plants is key. During the winter-to-spring transition, farmers should choose plants that meet the commercial standards of their variety. These plants should exhibit typical traits, such as late bolting, compact internodes, no lateral branches, few leaves, thick stems without cracks, and no signs of pests or disease. Any unsuitable plants should be harvested and sold. Each selected plant should be marked and numbered separately to maintain genetic purity.
Third, field management is important for healthy growth. Remove any excess or dead leaves, loosen the soil, and ensure proper drainage by opening ditches and keeping them clear. To prevent lodging due to wind or rain, it's advisable to insert stakes. Lettuce is also prone to diseases like downy mildew and aphids, especially in the later stages. For downy mildew, apply 25% metalaxyl diluted 400–500 times, starting at the first sign of infection and repeating every 7–10 days for 2–3 applications. For aphid control, use 10% imidacloprid (also known as Confidor, Kang Fuduo, or others) diluted 2500–3000 times.
Finally, timely harvesting is essential. When the flowers turn brown and white hairs appear on the inflorescence, the seeds are nearly mature and should be harvested promptly. Delaying harvest can cause the white hairs to be blown away by wind or washed away by rain, leading to seed loss or spoilage. Since different parts of the plant mature at different rates, it's best to harvest in stages or wait until most of the inflorescences are mature before drying the seeds.
