Qu'est-ce que Freeze-Dried Garlic Granules (5 mm, Natural Allicin) ? Applications, dosage, alternatives et spécifications

Freeze-dried Garlic granules are naturel dehydrated garlic products processed from fresh garlic (Allium sativum L.) through selection, peeling, dicing, low-temperature pre-freezing, and vacuum freeze-drying. Freeze-dried garlic granulés are typically cube-shaped particles with a side length of approximately 5mm, appearing creamy white to light yellow, with a rich and pure garlic aroma and pungent flavor. Freeze-dried garlic granulés are a representative product of freeze-dried foods (FD) and represent a premium dehydrated vegetable product produced using vacuum freeze-drying technology. Unlike traditional hot-air dried (AD) dehydrated garlic granulés, freeze-dried garlic granulés are dehydrated under low-temperature and vacuum conditions, maximizing the retention of the color, flavor, taste, nutritional components, and active substances of fresh garlic. Freeze-dried garlic granulés are inherently pure, naturel, additive-free food ingredients, with garlic as the sole component, containing no salt, sugar, colorings, or conservateurs. Le produit has extremely low moisture content (typically ≤5%), excellent rehydration properties, and an extended durée de conservation (24 mois). Freeze-dried garlic granulés can be used directly in cooking, seasoning, and food processing, or ground into poudre.

The core characteristics that distinguish freeze-dried garlic granulés from other dehydrated garlic products stem from its unique processing technology: 1 Maximum Retention of Naturel Flavor and Aroma Compared with dehydrated garlic granulés produced by hot-air drying, freeze-dried garlic granulés not only preserve proteins, vitamins, and heat-labile components intact, but also minimize the loss of allicin and other flavor compounds, maximizing the retention of the color, flavor, taste, nutritional components, and active substances of fresh garlic. Compared with hot-air drying, the freeze-drying process prevents the development of bitterness or burnt flavors, locking in the complete garlic aroma. 2 Excellent Rehydration and Quick Reconstitution Freeze-dried garlic granulés have a porous structure that allows rapid rehydration in soups, sauces, huiles, or marinades, restoring a bright garlic flavor very close to fresh cloves. Just one spoonful of water can reconstitute them into fresh garlic pâte. This rapid reconstitution capability gives them high application value in ready-to-eat foods, soups, and sauces. 3 Extremely Faible Humidité Teneur and Extended Durée de Conservation Freeze-dried garlic granulés have extremely low moisture content (typically ≤5%), with some premium products reaching 1%–3%. The low water activity effectively inhibits microbial growth and enzymatic reactions, resulting in a durée de conservation of up to 24 mois under sealed, protected-from-light, cool, and dry conditions. 4 Pur and Naturel, Clean Label Freeze-dried garlic granulés are 100% pure naturel products, containing no additives, conservateurs, or artificial colors. They are non-GMO, sans gluten, and suitable for véganes, perfectly aligning with the clean label trend. 5 Light and Crisp Texture, Easy to Process Freeze-dried garlic granulés have a lightweight, porous, and crispy texture, facilitating grinding into poudre and uniform dispersion in food processing. The bulk density est unpproximately 0.65–0.75 g/cm3.

The industrial production of freeze-dried garlic granulés is centered on vacuum freeze-drying technology, with the core production flow as follows: Fresh Garlic → Selection → Stalk Cutting → Peeling → Dicing (5mm cubes) → Tray chargement (2 layers) → Faible-temperature Pre-freezing (-20°C to -30°C, 4h) → Vacuum Freeze Séchage (cold trap -45°C to -35°C, vacuum <12Pa) → (Optional Microwave Vacuum Séchage) → emballage Core Process Steps: 1 Selection and Pretreatment: Select fresh, plump, haute qualité garlic free from insect damage and mildew. Remove garlic through manual sorting. After stalk cutting, peel the garlic cloves mechanically or manually. 2 Dicing and Tray chargement: Use a multi-kinetic dicing machine to cut peeled garlic cloves into cube-shaped garlic granulés with a side length of 5mm. When loading trays, spread 2 layers of material per tray, with the center slightly thinner and the edges slightly thicker to ensure uniform drying. 3 Faible-temperature Pre-freezing: Pre-freeze the tray-loaded garlic granulés at -20°C to -30°C for 4 hours. The purpose of pre-freezing is to form fine ice crystals within the material, protecting the cell structure. 4 Vacuum Freeze Séchage: After pre-freezing, lower the cold trap temperature to -45°C to -35°C, load the material into the freeze-drying chamber, and evacuate to below 12Pa for vacuum freeze drying. Under low-temperature vacuum conditions, ice crystals sublimate directly into water vapor and are removed. The drying time est unpproximately 7 hours. 5 Combined Séchage (Optional): Some avancé processes use combined vacuum freeze drying and microwave vacuum drying—after freeze drying to 30% moisture content, transfer the trays to a microwave vacuum dryer and dry at 420W power for 15–20 minutes to below 6% moisture content. This combined process maintient the excellent quality of freeze-dried garlic granulés while shortening drying time and reducing energy consumption. 6 emballage: After drying, the garlic granulés are sealed and packaged in GMP clean workshops, using double sac PEs or nitrogen-flushed aluminum sac aluminiums (O2<0.5%, light-blocking).
