Freeze-dried Carrot Granules (FD carrot Granules)
Freeze-dried carrot granules are pure fruit and vegetable raw materials in granular form made from fresh carrots through vacuum freeze-drying (FD) technology. The entire process is free of additives and can retain the color, flavor and nutrition of fresh carrots to the greatest extent. They rehydrate quickly and have a long shelf life, making them a popular ingredient in the food industry and healthy diets.
I. Basic Characteristics
（1）Raw materials: 100% fresh non-GMO carrots, free of pesticide residues, additives and preservatives.
（2）Appearance: Orange-red/bright orange, uniform particles (common 3×3mm, 5×5mm, customizable), loose and porous texture, light and brittle, with natural luster.
（3）Smell: Natural, sweet and refreshing carrot aroma, no off-flavors.
（4）Moisture content: ≤5% (far lower than 10% – 15% when air-dried).
（5）Shelf life: 24 months (Store in a cool, dry and sealed place).
（6）Rehydration property: Quick rehydration within 3 to 5 minutes, restoring fresh shape and taste, superior to air-drying.
Ii. Core Process (Vacuum Freeze-Drying FD
（1）Raw material selection: Fresh carrots that are moderately ripe, free from rot and lignification.
（2）Cleaning and peeling: High-pressure cleaning, mechanical/manual peeling, and impurity removal.
（3）Dicing/granulation: Cut into uniform small particles (3-10mm).
（4）Blanching and color protection: Blanch in hot water at 80-95 ℃ for a short time to inactivate enzymes, protect color and inhibit bacteria.
（5）Rapid pre-freezing: Freeze rapidly at -18℃ to -40 ℃ to form fine ice crystals, protecting the cell structure.
（6）Vacuum sublimation drying: Under a high vacuum of 0.1mbar, the temperature rises slowly (from -25℃ to +40℃). Ice directly sublimates into water vapor, and the freshness is locked in at a low temperature (the entire process is < 40℃).
（7）Screening and packaging: Grading screening, metal detection, aseptic packaging (aluminum foil bags/double-layer PE bags).
Iii. Nutritional Components (Per 100g, concentrated dry product)
（1）Calories: Approximately 312-333kcal.
（2）Protein: 7.9-8.3g.
（3）Dietary fiber: 23-25 grams (5-6 times fresh).
（4）Beta-carotene: 16-18mg (3-4 times fresh, can be converted into vitamin A).
（5）Vitamin C/E: Retention rate over 90% (only 50% – 60% when air-dried).
（6）Minerals: Highly concentrated potassium (about 246mg), calcium, magnesium, iron, etc.
（7）Features: High nutritional density, low fat, low sodium, natural sugar-free, suitable for people who need to control blood sugar and lose fat.
Iv. Key Differences between FD and AD (Air-Drying)
(1)Nutrient retention: FD 90% – 95%; AD 50% – 70% (severe vitamin loss).
(2)Appearance and color: FD bright orange-red, plump in shape; AD shows dullness, shrinkage and Browning.
(3)Taste: FD is crispy and tender after rehydration. AD is hard and dry, but tough and tough after rehydration.
(4)Rehydration speed: FD 3 to 5 minutes; AD 15 to 30 minutes.
(5)Shelf life: FD 24 months; AD: 12 to 18 months.
(6)Price: FD is approximately 2 to 3 times that of AD (with higher process costs)
V. Main Application Scenarios
(1)Convenience foods: Instant noodle/vermicelli seasoning packets, freeze-dried instant soup, porridge seasoning packets, self-heating rice, quick rehydration, good color, high nutrition.
(2)Snack foods: Mixed fruit and vegetable crisps, energy bars, granola, pet snacks, crispy, sweet and guilt-free.
(3)Baking and dairy products: Bread, cakes, muffins, yogurt/ice cream ingredients, enhancing color, aroma and nutrition.
(4)Catering and home: Fried rice, soups, fillings, salads, no need to cut or wash, ready to use after soaking, fresh taste.
(5)Nutritional meal replacement and complementary foods: meal replacement powder, infant and toddler complementary foods, elderly nutritional meals, high fiber, high beta-carotene, easy to digest.
Freeze-dried carrot granules are natural fruit and vegetable ingredients with low-temperature freshness retention, high nutrition, long shelf life and high rehydration. Compared with air-dried products, they are comprehensively superior in nutrition, taste, appearance and convenience. They are widely used in convenience foods, snacks, baking, catering, healthy diets and other fields, and are the preferred raw materials for modern food industry and healthy living.
