Harvesting goji berries requires careful attention to timing, handling, and drying methods. After the flowers fall, the fruits begin to develop as small green buds, gradually turning into orange-colored fruits. At this stage, the flesh is still firm. As they continue to ripen, the fruits become bright red. The optimal time for harvesting is when the fruit feels slightly soft and loose, indicating full maturity. If harvested too early, when the fruit is still orange, it will turn yellow after drying, which negatively affects its quality and market value.
Second, avoid harvesting when the fruits are wet. Do not pick them in the morning when dew is still present or after rain has not fully dried. Wet fruits take longer to dry and are more prone to bacterial contamination.
Third, handle the fruits gently. When picking, avoid bruising or damaging them. Use containers like baskets, buckets, or pots—never plastic bags, as they can cause crushing or impact during transport. Any bruising or damage will result in black spots after drying.
Fourth, avoid direct exposure to intense sunlight. After sunrise, allow the fruits to air-dry gradually, starting with low light and slowly increasing to stronger sunlight and higher temperatures. This helps maintain a bright red color. However, exposing the fruits to strong midday sun may cause them to darken.
Fifth, do not leave the fruits unprocessed for too long. Once picked, they should be dried promptly. Freshly harvested fruits have high respiration rates and can easily sweat or overheat if left for too long, leading to dull, lower-quality dried berries.
Sixth, avoid turning the fruits during the drying process. Turning them can cause internal damage, resulting in blackened areas after drying. Once the fruits are spread out to dry, they should remain undisturbed until fully dried.
Seventh, never use sulfur fumigation. Although sulfur may make the fruits appear brighter, it introduces harmful chemicals and reduces their quality. To achieve high-grade, safe, and naturally sweet goji berries, all aspects of the drying process must be carefully controlled, ensuring no chemical additives are used.
