I. Core Functions
Silica Gel Desiccant for food acts as a “moisture-proof guard” in food storage and transportation. Its core function is to absorb moisture inside food packaging, inhibit the growth of mold and bacteria, prevent food from getting damp, caking or deteriorating, thereby extending the shelf life and ensuring food quality and edible safety.
II. Correct Usage Methods
1. Match dosage with food weight: Add 2-5 grams of Silica Gel Desiccant per kilogram of food, and select the appropriate specification as needed.
2. Seal the packaging: After placing the Silica Gel Desiccant together with the food into the packaging bag, seal the bag tightly immediately to ensure no air leakage gaps.
3. Environmental requirements: Store food in a dry and ventilated place, away from direct sunlight and high-temperature environments, to enhance moisture-proof effect.
III. Usage Notes
- Forbidden to eat: Silica Gel Desiccant is a chemical moisture-absorbing material, which should be kept away from children and pets to prevent accidental ingestion.
- Avoid direct contact: Do not let the Silica Gel Desiccant touch food directly to prevent food contamination.
- Keep the environment dry: Avoid humid environments during use and storage, otherwise the moisture absorption efficiency of the Silica Gel Desiccant will be reduced.
- Standard storage: Unused Silica Gel Desiccant should be stored in a cool, dry and ventilated place, away from direct sunlight and high temperature.
IV. Common Types & Selection
- Classified by specification: Common models include 1g, 2g, 3g, 5g, etc., which can be flexibly selected according to the size and weight of food packaging.
- Classified by color: There are white, blue, orange and other types. Different colors of Silica Gel Desiccant will change color when fully saturated with moisture (e.g., blue turns pink), which is convenient to judge whether it is invalid. It can be selected according to the needs of the use scenario.
V. Maintenance & Reuse
- Regular replacement: After using for a period of time, if the Silica Gel Desiccant loses its moisture absorption capacity (such as color change, damp feel), it should be replaced in time.
- Regeneration treatment: Damp and invalid Silica Gel Desiccant can be put into an oven and baked at about 200℃ for 1-2 hours. After restoring the dry state, it can be reused (only for uncontaminated Silica Gel Desiccant).
