[0021] The preparation method of the edible flower extract comprises the steps of pretreatment, extraction and concentration, specifically including:
[0022] A. Pre-treatment: Take raw edible flowers and crush them through a 20-60 mesh sieve for later use;
[0023] B. Extraction: Add water or ethanol with a solid-to-liquid volume ratio of 1-5 times to the pre-treated edible flowers, stir and extract at a temperature below 60°C for 0.5-3 hours, extract 1-3 times, filter, and combine the filtrates;
[0024] C. Concentration: Concentrate the filtrate below 60°C to a relative density of 1.05~1.25, and dry it at a low temperature below 60°C to obtain the target product.
[0025] The filtration described in step B refers to the technology that can clarify the liquid, including but not limited to centrifugal separation (such as tube centrifugal equipment, sedimentation centrifugal equipment), plate and frame filtration, titanium rod filtration, cartridge filtration, plate filtration...
Embodiment 1
[0047] Take 3000g of dried rose flowers, crush them, add 4500ml of water, stir and extract at room temperature for 0.5 hours, plate filter, add 3000ml of water to the solid part again, stir and extract for 0.5 hours, plate filter, combine the liquids, concentrate the membrane of direct reverse osmosis into a thick paste, add 900g of honey and 180g of starch dextrin are imported into a high-speed mixing granulator, granulated, and sent to a belt-type vacuum dryer. The belt speed is adjusted to 15cm / min, and the vacuum degree is controlled at 0.078-0.081MPa. The first and third stages control the temperature of the material below 60°C, and the cooling temperature of the fourth stage is controlled at 25°C, and the material is continuously dried and discharged, and then packed and boxed. The water activity of the product drops below 0.6, and it can be stored for a long time without deterioration. When taking it, dissolve it with water at room temperature, and shake it for 15 secon...
Embodiment 2
[0049] Take 1500g of rose flowers and 1500g of jasmine flowers, crush them, add 3500ml of ethanol and stir at low temperature, control the liquid temperature below 60°C, extract for 0.5 hours, filter in a cylinder, add 3500ml of ethanol to the solid part again and stir at low temperature, control the liquid temperature below 60°C, Extract for 0.5 hours, filter in a cylinder, combine the liquid, use a vacuum heating concentrator to control the liquid temperature below 60°C and concentrate it into a thick paste, use a vacuum drying oven to control the product temperature below 60°C to dry, add 900g of honey, 18g of water-soluble starch, Import the dry roller press granulator, granulate, discharge, pack and box. The water activity of the product drops below 0.6, and it can be stored for a long time without deterioration. When taking it, dissolve it with water at room temperature, and shake it for 15 seconds to dissolve completely. The color, aroma and taste are well preserved, an...
