Garlic Deep Processing Industry

1. www.amisyfoodmachine.com info@amisymachine.com Garlic Deep Processing Industry 1. GarlicOverview 1.1 Garlicspecies Garlic(Allium sativum) is a species in the onion genus, Allium. It is native to central Asia, and has been used for both culinary and medicinal purposes. There are two subspecies of allium sativum: hardneck (Allium sativum ophioscorodon) and softneck (Allium sativum sativum). 1.11 Hardneck garlic Hardneck garlic grow best in cold climates. Hardnecks have a hard central stalk and produce deliciouscurled scapes from the top. Removing the scapes encourages largerbulbs. Hardneck garlics have fewer, larger cloves than the softnecks, and have little or no papery outer wrapper. Hardneck garlic has a rich and complex flavor. Porcelain, pocambole, and purple stripe types are hardnecks. 1.12 Softneck garlic Softneck types grow best in mild climates. It is the type found most often in the grocery store. Softneck garlic has a white, papery skin. It doesn’t produce scapes, and has more cloves forming several layers surrounding the core. Softnecks mature faster than hardnecks and keep longer. The flexible stem makes it ideal for braiding. Flavor of softneck garlic is generally mild. Most processed garlic foods, like garlic powder and seasoning, come from softneck garlic. Artichoke and Silverskin are two types of softneck garlic. 1.2 Health benefits and uses 1.21 Nutritional value One raw clove(3g) contains 4 calories, 0.02g fat, no cholesterol, 1mg sodium, 1g carbohydrates, 0.2g protein.

Garlic is consumed fresh as well as used as a condiment in various food preparations like pickles, chutneys, curries powders, sauce, salad dressings, meat sausages,etc. 2. GarlicDeep Processing Technology andProcessed Garlic Products 2.1 Garlicdeodorization Fresh garlic contains Alliin and an enzyme called Alliinase, each kept in separate cells. When garlic is chopped or crushed, the enzyme alliinase contacts with alliin and converts alliin into allicin. Allicin is very unstable and breaks down quickly producing allyl methyl sulfide. The chemical goes into our blood stream and gets expelled through skin’s pores when we sweat causing garlicky sweat. It also enters our lungsand comesout as we exhale causing garlic breath. The odor of garlic poses negative influence on its application. Therefore, it’s important to choose a proper deodorizing method during garlic deep processing. Two methods are listed as follow: 1). Add 5kg water and 100g vinegar to every kilogram of garlic and mix evenly. Allow to boil for 15 minutesand then cool to ambient temperature. Clean the garlic with water. 2). Put the garlic in the solution made by 0.3% citric acid, 0.2% cyclodextrine, and 0.1% magnesiumchloride, soak for 3 hours at 50℃, then rinse with clean water. 2.2 Garlicproducts in the industry There are many types of garlic products in the market, including garlic flake, garlic powder, garlic oil, aged garlic extract, black garlic, etc. Tel: 86-0371-65903478 Fax: 86-0371-65903401

Garlic slicing machine With garlic slicing machine, clean garlic cloves are uniformly sliced to 1.5-2.2mm. The surface of garlic slice is smooth without damage. (5). Garlic rinsing machine Sliced garlic are washed again in the rinsing machine. (6). Garlic dehydration machine Garlic slicesare processed by the centrifugal dewatering machine to remove surface water. (7). Garlic drying machine Dehydrated garlic flakes are spread uniformly on the drying tray and dried in the hot air drying oven at 65℃ for about 6 hours. The final moisture content should be less than 5%. (8). Garlic grading machine Dried garlic slicesare graded by garlic grading machine. Unqualified productsare removed. (9). Garlic packing machine Dried garlic slicesare packed by garlic packing machine for safe storage. 2.22 Garlic powder Tel: 86-0371-65903478 Fax: 86-0371-65903401

5. www.amisyfoodmachine.com info@amisymachine.com Garlic powder can be made by grinding dried garlic flakes in the garlic grinding machine into fine powder. If you make it coarser, it will be granulted garlic. Garlic powder can also be made in the following process: garlic separating→garlic drying→garlic powder crushing→garlic powder packing peeling→garlic grinding→garlic dehydration→garlic paste Garlic powder production line mainly includesthe following equipments: (1). Garlic separating machine Garlic bulbs are separated into cloves by garlic separating machine. (2). Garlic peeling machine Garlic cloves are peeled by using garlic peeling machine. (3). Garlic paste making machine Peeled garlic cloves are put into the garlic grinding machine which grinds the cloves into paste. (4). Garlic paste dehydrationmachine Garlic paste are put intothe centrifugal dewatering machine to remove water. (5). Garlic drying machine Dehydrated garlic powder are spread uniformly on the drying tray and dried in the hot air drying oven at 55℃ for about 6 hours. The final moisture content should be less than 5%. (6). Garlic powder crushing machine Garlic powder crushing machine grindsthe dried powder into fine powder. (7). Garlic powder packing machine Garlic powder is packed by garlic packing machine automatically and store for sale. 2.23 Garlic oil Garlic oil is mainly obtained by steam distillation from the crushed garlic. The working process is as follows: Garlic distillation→ separation → refining → packing separating→garlic peeling→garlic washing→garlic crushing→fermentation→steam First the bulbs are separated into cloves, and then the cloves are peeled. After cleaning and crushing, 2-folds of water are added and the mixture are fermented at 55℃ for 3 hours. Then the mixture are subject to steam distillation. The distillate is separated by oil-water separator to get crude oil. The crude oil is refined and packed. This method has the advantages of simple equipment, low cost and good stability. Vegetable oil is usually added to refined oil to make capsules. 2.24 Aged garlic extract Aged garlic extract is produced by extraction and aging of fresh garlic at room temperature for up to 20 months in stainless steel tanks. During this period, harsh unstable compounds, such as allicin in fresh garlic are converted into stable health-promoting substances. 2.25 Black garlic Black garlic is produced through fermentation by heating whole bulbs of fresh garlic at high Tel: 86-0371-65903478 Fax: 86-0371-65903401
