Embodiment 1

[0026] Choose a ripe fresh watermelon that is free from pests and diseases and rot, wash it with clean water and then soak it in a 0.01% potassium permanganate solution for 3-4 minutes to disinfect, and then clean it with sterile water. Cut the watermelon into two halves, take the flesh of the watermelon, and squeeze the juice with a juicer. Filter with a 60-mesh vibrating sieve to remove some watermelon seeds and large particles of pulp remaining in the watermelon juice. The mature passionfruit fruit is washed with clean water and then beaten in a beating machine to obtain passion fruit pulp. To produce 1 ton of beverage, add 500kg of watermelon juice, 150kg of passion fruit pulp, 100kg of white sugar, 1kg of acacia, 0.5kg of xanthan gum, 2kg of malic acid, 0.5kg of potassium sorbate, and 0.1kg of sodium D-isoascorbate , Pure water makes up the balance. A high-pressure homogenizer is used to homogenize the beverage. The homogenization temperature is 65°C, the pressure is 30M...

Embodiment 2

[0028] The freshly harvested watermelon is peeled and cut into appropriate sizes, sealed and packed with polyethylene plastic film, about 10kg per bag. The packaged watermelon is quickly sent to a freezing condition of -20°C to -30°C for 12 hours, and then the frozen watermelon is placed in a freezer below -18°C for freezing. Before processing the beverage, take out the watermelon in the bag, together with the packaging bag, defrost it with a tunnel microwave heating machine, and then squeeze the juice with a juicer. Filter with an 80-mesh vibrating sieve to remove some watermelon seeds and large-particle pulp remaining in the watermelon juice, and set aside. After washing the mature fruit of passion fruit with clean water, it is beaten with a beating machine to obtain passion fruit puree. Based on the production of 10 tons of beverages, weigh 8000kg of watermelon juice, 1000kg of passion fruit syrup, 400kg of high fructose syrup, 200kg of white sugar, 5kg of gum arabic, 5kg o...

Embodiment 3

[0030] Choose a ripe fresh watermelon that is free from pests and diseases and rot, wash it with clean water, soak it in a 0.01% potassium permanganate solution for 4 minutes, and then clean it with sterile water. Cut the watermelon into two halves, take the flesh of the watermelon, and squeeze the juice with a juicer. Filter with 60 mesh vibrating screen. The mature passionfruit fruit is washed with clean water and then beaten in a beating machine to obtain passion fruit pulp. To produce 5 tons of beverages, add 4500kg of watermelon juice, 250kg of passion fruit syrup, 200kg of high fructose syrup, 5kg of gum arabic, 5kg of xanthan gum, 6kg of malic acid, 4kg of citric acid, 1kg of potassium sorbate, and D-isoascorbic acid Sodium 0.5kg, pure water makes up the balance. A high-pressure homogenizer is used to homogenize the beverage. The homogenization temperature is 65°C, the pressure is 20MPa, and the number of homogenization is 2 times. The beverage is degassed by a degass...
