2.3 Bioactive ingredients and nutritional makeup of pineapple
waste and derived products
Bioactive components can be found in abundance in pineapple waste.
The crown, peel, stem, and core make up the majority of the trash
produced by pineapple. The pharmaceutical and food industries are
also very interested in the phenolic substances present in pineapple
leftovers because of their biological characteristics, which have health
implications. Myricetin, salicylic acid, tannic acid, trans-cinnamic acid,
and p-coumaric acid are a few examples, which, according to reports,
are potent antioxidants, were found in a high dietary fiber powder
prepared from leftover pineapple shells. However, studies have shown
that pineapple waste contains polyphenols, like ferulic acid and
syringic acid, which are what give the fruit its antibacterial and
antioxidant benefits. Additionally, glycosides derived from these
residues have numerous uses as prebiotics, bio preservatives, and
food additives. In addition to bromelain, a family of proteases with
numerous applications in the manufacture of food, textiles, cosmetics,
and even animal feed, pineapple waste also contains insoluble fibers,
pectins, sugars, protein, vitamins, minerals, and phenolic compounds.
The endopeptidase bromelain, which is found in the stem and fully
matured fruit, is a proteolytic enzyme that breaks down protein [15]. It
is anticipated that the bromelain found in pineapple waste and
byproducts will break down the protein in fish meals to increase the
number of simple amino acids, Consequently, the feed conversion
ratio (FCR) of animals is reduced, and livestock production is raised.
Moisture (82–88%), crude protein (5–9%), crude fat (2–3%), fiber (1-
6%), ash (4-6%), and carbohydrates (50–80%) make up the majority
of the ingredients in pineapple peels [20], [27], [32]. The pineapple
core's approximate composition is as follows: moisture content:
84.9%; crude protein: 3.6%; crude fat: 2.35%; crude fiber: 9.14%; ash:
1.7%; and carbohydrate: 83.03%2 [20]. In terms of moisture content,
