2. Application Scope
It is dedicated to decolorization and bleaching of various edible oils. It can efficiently remove carotenoids, chlorophyll, oxidized pigments and colored impurities in soybean oil, rapeseed oil, palm oil, animal oil and other edible oils, improve oil transparency and color uniformity, and reduce oil loss. It can replace traditional bleaching earth, suitable for physical/chemical refining, crude oil bleaching and high-end edible oil color optimization, complying with global edible oil bleaching environmental protection standards.
3. Manufacturing Advantages
We have professional bleaching silica gel production technology and pigment detection equipment, establishing a precise decolorization performance control system. GMP food-grade production workshops are certified by ISO22000 and FDA, with stable mass production capacity to meet global large-scale edible oil bleaching demand. We support parameter customization according to oil pigment content, lead time of 5-10 working days, providing bleaching process optimization guidance.
4. Shipping & Packaging
- Standard Packaging: 20/25kg paper-plastic composite bags with built-in desiccant, moisture-proof and anti-agglomeration.
- Storage & Transportation: Store in cool, dry, sealed and light-proof environment; non-hazardous chemical, supporting global sea and land transportation.
- Marking Norms: Clearly label bleaching-specific attribute, decolorization rate and addition limit; multilingual labels and test reports are available.
5. FAQs
Q: Will bleaching affect the nutrition and flavor of edible oil?
A: No. It only adsorbs colored impurities in a targeted manner, without adsorbing beneficial components such as vitamins and sterols, retaining the original flavor and nutrition of oil.
Q: Is it suitable for low-temperature bleaching of high-end edible oil?
A: Yes. It can work normally at 30-80℃, low-temperature bleaching better retains oil nutrients, ideal for olive oil, camellia oil and other high-end edible oils.
