(1) Raw Material Selection and Preparation: It is recommended to use fully matured, green-ripe pineapples that are free from diseases and pests. The fruit should be washed twice with tap water to ensure cleanliness. After washing, the skin is removed using a stainless steel knife, and the fruit is cut into small pieces measuring either 2cm x 2cm or 2cm x 5cm for easier processing. These pieces are then set aside for further steps.
(b) Candying and Sugar Soaking: Place the pineapple slices or pieces into a stainless steel pot. Add 30% white sugar by weight and mix thoroughly. Let the mixture sit for 6 to 12 hours to allow the sugar to penetrate the fruit. After this period, transfer the fruit along with the syrup into a boiling pot and let it cool for about an hour. Once cooled, leave the fruit at room temperature to soak for an additional 12 hours, allowing the flavors to develop further.
(3) Draining and Drying: Using a stainless steel mesh spoon, carefully remove the candied pineapple from the syrup. Drain off any excess liquid and spread the fruit evenly on a baking tray. Place the tray in a drying oven and dry until the moisture content reaches 28%. At this point, stop the drying process, remove the fruit, and allow it to cool naturally at room temperature.
(D) Packaging and Storage: Once dried, the preserved pineapple is packaged in food-grade plastic bags, sealed properly, and stored in a cool, dry place. This helps maintain quality and extends shelf life.
(5) Precautions:
1. Pineapple contains a high level of fiber and natural acids, which can affect the texture of the final product. The crispness of the candied fruit is closely related to the sugaring time. Experiments have shown that the optimal sugaring time is 60 minutes, resulting in a product with good crispness, balanced acidity and sweetness, a golden color, and good transparency.
2. To ensure a high-quality finished product, the sugar content must reach a certain level. When the sugar concentration exceeds 65%, the preserved pineapple can last more than six months under normal storage conditions. However, current consumer trends favor low-sugar and healthy food options, so adjustments may be necessary to meet market demands.
