The processing of mixed fruit jam involves preparing and cooking a mixture of pineapple, orange, strawberry, and sugar to create a delicious spread commonly used on toast or pastries. The fruits are first cleaned, peeled, and chopped before being cooked with sugar to release their natural juices and flavors. The mixture is then simmered until it thickens and reaches the desired consistency for jam. The final product is then poured into sterilized jars and sealed to ensure freshness and preservation.
