Examples
Embodiment 1
[0057] In Example 1, first take 20 g of longan pulp, add 100 mL of water to soak for 12 hours, add 180 mL of water, mash it with a crusher, and use pectinase and cellulase in a ratio of 3:1 to enzymolyze it simultaneously. The enzymolysis time is 30min, and the enzymolysis temperature is 60°C. After the enzymatic hydrolysis treatment, the enzyme was inactivated at 90°C for 30 minutes, the filtrate was collected by 200-mesh filtration, and the total soluble solids (TSS) content was measured with an automatic constant temperature refractometer (20°C).
[0058] Then configure the suspension: put the extracted soluble solids into water, and configure the suspension with the feed concentration at the B level. Then configure the auxiliary drying agent mixed solution: add the auxiliary drying agent to the above suspension, use a mixer to stir for 30 minutes, and the stirring speed is 800r / min to obtain a uniform mixed solution. Wherein the co-drying agent comprises 11% maltodextrin,...
Embodiment 2
[0062] In Example 2, first take 20 g of longan pulp, add 100 mL of water to soak for 12 hours, add 180 mL of water, mash it with a crusher, and use pectinase and cellulase in a ratio of 3:1 to enzymatically hydrolyze it simultaneously. The enzymolysis time is 30min, and the enzymolysis temperature is 60°C. After the enzymatic hydrolysis treatment, the enzyme was inactivated at 90°C for 30 minutes, the filtrate was collected by 200-mesh filtration, and the TSS content was measured with an automatic constant temperature refractometer (20°C).
[0063] Then prepare the suspension: put the TSS extracted by enzymatic hydrolysis into water, and prepare a suspension with a feed concentration of B level. Then configure the auxiliary drying agent mixed solution: add the auxiliary drying agent to the above suspension, use a mixer to stir for 40 minutes, and the stirring speed is 800r / min to obtain a uniform mixed solution. The co-drying agent includes 11% maltodextrin, 1.25% gum arabic,...
Embodiment 3
[0067] In Example 3, first take 20 g of longan pulp, add 100 mL of water to soak for 12 hours, add 180 mL of water, mash it with a crusher, and use pectinase and cellulase in a ratio of 3:1 to enzymolyze it simultaneously. The enzymolysis time is 30min, and the enzymolysis temperature is 60°C. After the enzymatic hydrolysis treatment, the enzyme was inactivated at 90°C for 30 minutes, the filtrate was collected by 200-mesh filtration, and the TSS content was measured with an automatic constant temperature refractometer (20°C).
[0068] Then prepare the suspension: put the TSS extracted by enzymatic hydrolysis into water, and prepare a suspension with a feed concentration of B level. Then configure the auxiliary desiccant mixture: add the auxiliary desiccant to the above suspension, use a mixer to stir for 50 minutes, and the stirring speed is 800r / min to obtain a uniform mixture. Wherein the co-drying agent comprises 9% maltodextrin, 0.5% gum arabic, 0.1% sodium alginate, 1.4...
