Nguyen Phuoc Minh
Marian plum is called the king of fruits not just for its taste and super flashy yellow color, but also for the array of health benefits it offers. We utilize this valuable fruit to produce a new marian plum jam. By mixing marian plum fruit with 55% sugar, 7% gelatin and 0.2% citric acid we conduct the heating at 75 oC within 5 minutes to get the best elasticity and sensory score of jam. Potassium sorbate 0.04% is enough to prolong jam shelf-life.
