ash, crude fiber, crude protein, and carbs, culled pineapple has a
content of roughly 83.8%, 0.45%, 0.69%, 1.19 percent, and 13.04%,
successively [9], [17]. The concentrations of moisture, ash, crude
fiber, crude protein, and carbs in culled pineapple are around 83.8%,
0.45%, 0.69%, 1.19 percent, and 13.04%, respectively [9], [17].
Variety, location, season, and pineapple ripeness affect the nutritional
composition of pineapple trash. The relative composition of the
various pineapple wastes indicates their well-shown capacity to
provide value [5].
In addition, fermentation leads to the hydrolysis and degradation of
proteins into shorter peptides and amino acids, it can be a very
efficient way to improve the nutritional value of fishmeal, which is used
as a protein source in feed [24]. Pineapple wastes have previously
been utilized as supplies for the synthesis of organic acids, wine,
vinegar, and yeast for the creation of food and feed proteins, as well
as for the extraction of bromelain. They can also be a source of other
bioactive compounds, such as antioxidants. The peel and crown of
pineapple are among the waste products consisting of lignin,
hemicellulose, and cellulose [33]. Using centrifugation, membrane
separation, microfiltration, and ultrafiltration, they were able to recover
a concentrated solution of proteolytic enzymes from the pineapple
waste liquid phase in this process. The inclusion of water or solvent
was avoided during the extraction process. The final enzymatic
sample, which was lyophilized, exhibited comparable proteolytic
activity to certain commercial preparations. The final results appeared
to suggest that sugar breakdown and the production of inhibitory
chemicals like furfural and hydroxymethyl furfural may be avoided. To
boost the saccharification of the lignocellulosic matrix, microwave-
assisted treatment was applied to the solid pineapple waste that had
been removed from the liquor [7]. A rise in pineapple trash could also
exacerbate the problem of insufficient garbage disposal sites and
related facilities.
Bromelain enzymes from pineapple have been used as an extra
element in fish and animal feed. Efforts have been made all over the
