Drying and grinding of pineapple fruit fibre using freeze drying technique

Malaysia being that a tropical country has favorably provided a suitable environment for various fruits to be cultivated. Such that one of the many fruit would be pineapple. Pineapple in general consisted of moisture and the rest would be the total solids in which of the total solids would be carbohydrates while fibers makes up to the rest. Pineapple fibers are considered to be in the pulp, shell, crown, leaves and the cores. In this paper the fiber of the pineapple core was used as the material because often in time they are being disregarded as waste or feedstock to animals. However, the level of protein in the core is higher than the flesh. Therefore, because of the core has higher protein value, they also have twice the amount of total soluble sugar. Pineapple being a tropical fruit that is rich in nutrient, ascorbic acid, minerals, fibers and antioxidants has make them after banana and citrus the third most traded fruit internationally. As the fruit industry evolves there is a demand for fruits to be consumed in different ways. This demand most likely arises due to the fact that fruits like pineapple has high moisture content and they are deemed as highly perishable product. Therefore, techniques like drying and grinding were introduced and implemented. With this the correlation between the desired to utilize the pineapple waste into a product and the problem face in fruit industries can be solved in this paper. This paper will focuses on the drying and grinding of the pineapple fruit fiber using freeze drying technique and a simple analysis on the taste, stickiness, scent, color and size of the product were provided
