The following\u00a0is our evaluation of three common products on the market.\u00a0Comparing with technology, appearance,\u00a0section,\u00a0texture, and\u00a0its condition in water,\u00a0the\u00a0total five projects of goji berry, we made an evaluation on\u00a0freeze-dried, oven-dried, and air-dried goji berry to make sure that you won\u2019t be taken in while choosing.<\/span><\/p>\n Comparison: a random choice of freeze-dried, oven-dried, and air-dried goji berries.<\/span><\/p>\n 1<\/span>.Production process<\/span><\/strong><\/p>\n <\/a><\/span><\/p>\n (From left to right\u00a0are\u00a0freeze-dried, oven-dried, and air-dried goji berries.)<\/span><\/p>\n Freeze-dried\u00a0goji berry: means goji berry will be frozen solid\u00a0by\u00a0using\u00a0Vacuum Freeze Drying\u00a0technology\u00a0which can make fruits dewater and\u00a0desiccate\u00a0by sublimation of ice\u00a0under the condition of low temperature and pressure.<\/span><\/p>\n Oven-dried goji berry: means people accelerate\u00a0the evaporation of water to achieve the purpose of drying\u00a0by increasing the temperature of drying room\u00a0artificially.<\/span><\/p>\n Air-dried goji berry: means people remove fruit wax on the surface with lye, then evaporate water from fresh fruit by turning them in the environment with full of sunshine and wind.<\/span><\/p>\n Analysis and conclusion: as for freeze-dried\u00a0goji berry,\u00a0under vacuum condition, water sublimate from its solid, the\u00a0material itself is left in the frozen ice shelf, so the dried volume won\u2019t be changed and goji berry will become loose, porous\u00a0with\u00a0good rehydration performance.\u00a0Retaining\u00a0the color, aroma, taste, shape and nutrition of the original food\u00a0is the strongest feature on freeze-drying technology.\u00a0Therefore, freeze-drying\u00a0food is also known as\u00a0space food, and\u00a0nowadays,\u00a0it is a natural, green, safe and convenient food.<\/span><\/p>\n For\u00a0Air-dried goji berry, goji berry will be\u00a0destroyed\u00a0what will cause the loss\u00a0of\u00a0nutrient\u00a0and darkening.\u00a0Some unscrupulous\u00a0factories\u00a0fumigate\u00a0with sulfur or dye the fruit to make it look delicious,\u00a0so that the\u00a0goji berry was\u00a0changed\u00a0from tonic to poison.<\/span><\/p>\n The technology of oven-dried goji berry is between the freeze-dried and air-dried. We will continue to evaluate other projects to let you know which one suits you most.<\/span><\/p>\n 2. Appearance\u00a0and\u00a0shape<\/span><\/strong><\/p>\n <\/a><\/span><\/p>\n Freeze-dried\u00a0goji berry: bright-colored, particles plump, dry with its\u00a0original\u00a0shape.<\/span><\/p>\n <\/a><\/p>\n Oven-dried goji berry:\u00a0dark red, slightly shiny,\u00a0a little plump\u00a0with flesh texture\u00a0and\u00a0irregular shape, not so dry on surface.<\/span><\/p>\n <\/a><\/p>\n Air-dried goji berry:\u00a0dark red, mat,\u00a0shriveled,\u00a0hard, and dry\u00a0with some foreign matters.<\/span><\/p>\n Analysis and conclusion: due to the different production process, dry goji berry shows great difference on its appearance. Comparing with oven-dried and air-dried, freeze-dried goji berry is bright and full; oven-dried goji berry looks more like abundant than the air-dried goji berry, because the opening making environment may bring some sands on the surface, fruits are easy to be influenced in this way.<\/span><\/p>\n 3.<\/span> Smell after\u00a0\u00a0cutting<\/span><\/strong><\/p>\n <\/a><\/span><\/p>\n Freeze-dried goji berry: can be cut easily, the internal pulp and fruit seeds are dry and dispersed gives fruity scent.<\/span><\/p>\n <\/a>Oven-dried goji berry: pulp tissues\u00a0are clearly visible, soft to touch, dry, without significant smell after cutting.<\/span><\/p>\n
