Put a lemon balm in a glass of water, after a few minutes, get a lemonade with flavor, color, taste . like fresh lemon juice.

This is the first study of passion fruit effervescent tablet in Vietnam by Master Ton Nu Thu Nguyet, Department of Food Technology, Department of Chemical Engineering, Ho Chi Minh City University of Technology.

Mr. Doan Thuong, a farmer with nearly 1 ha of passion fruit in Bong Lai village, Hiep Thanh commune, Duc Trong district, Lam Dong province, said: 'Farmers are often forced to price when the harvest comes. The locality also has some factories processing juice, bottled water, but not very professional, so farmers still do not have stable output '. Listening to the passionate effervescent tablet, Mr. Thuong was very excited, hoping that when the effervescent tablet was commercially produced, farmers would benefit more and be able to get rich in passion fruit.

Passion fruit (also known as cool cool) is a popular fruit, because of this, many people have bought aromatherapy mixed with sugar to deceive consumers.

In addition to selling fresh, some establishments in Da Lat, Duc Trong, Don Duong (Lam Dong province) also processed as local specialties in the form of juice, bottled water . however these products are limited. Time to use and clean food.

According to Oriental medicine, passion fruit helps reduce asthma symptoms; prevent coronary heart disease; reduce the growth of cancer cells; heat bar; Contains sleep-inducing ingredients. In addition, this fruit also contains iron and potassium which are very beneficial for health.

In addition to making lemongrass pellets, Master Nguyet has also succeeded in creating passion fruit powder with spray drying technology. Currently, Master Nguyet hopes to transfer the technology of producing passion fruit powder and passionate nectar tablets to help businesses commercialize the product and create a stable output for farmers.

The ripe lemons in the harvested Lam Dong region are separated, taking the intestines inside the preliminary processing to collect 'puree', juice. On average, 1kg of fresh fruit will yield about 400g of juice. The juice will be concentrated at a temperature of 60 degrees Celsius in the accompanying conditions: vacuum degree, rotation speed of the juice .

After two hours, the juice will reach 60% anhydrous. If this kind of juice is processed, it will not lose the flavor, color and ease of use for later mixing stages.

From anhydrous juice of 60%, mix with sugar at the ratio of 8: 3. After that, continue to dry and dry under appropriate conditions, until 5% moisture is reached. In order to make lemon balm easy to dissolve and foam, Master Nguyet and her colleagues added carbonate with a content of 2%. This supplemented carbonate will work with the acid available in the juice, when dissolving lemon juice with added ingredients into the water will release CO2 to make the passion fruit melt faster.

After mixing, drying is pressed to 3.5% moisture to create the final product called passion fruit nectar. Put the nectar pellet in the water for a few minutes and have a glass of lemon juice that is no different from nature. Dissolve 25g effervescent tablets in 75g warm water, will produce 100g of passion fruit nectar.

Random test results of over 60 people in color, speed of dissolution, taste . have shown almost absolute high satisfaction.
