Green Extraction Of Polyphenolics As Potential Bioactive Components From Pineapple Skin: A Review.

[摘要] Polyphenol is naturally occurring diversified molecular and different structure secondary metabolitefound in plant. It is responsible for the color, flavor, astringency odor and oxidative stability in plant. In humanalso it’s prevent from different degenerative diseases and diseases related to oxidative stress like cancer,cardiovascular, osteoporosis and neurodegenerative diseases. Therefore, researcher are showing interest toknow the health benefits of each polyphenol present in plant, fruits and vegetables. However, waste generatedform plant, fruits and vegetable also has potential to contain the polyphenol, one of such fruit is pineapple.Pineapple is very famous fruit cultivated worldwide and generate approx. 50% of waste as such or whileprocessing in pineapple processing industries. Pineapple waste mainly consist of crown, skin (peel) and core. Andeach portion of waste has immense potential in term of natural occurring polyphenol. Through different studiesit has confirm that pineapple peel is a good natural source of polyphenol which is ranging from 7.97 ± 0.63 to10.62 ± 0.37 mgGAE/g dw. Polyphenol found in pineapple peel is extracted by using different extractiontechnique. Extraction technique are mainly conventional or non-conventional, non-conventional technique ismost popular because it requires less time and solvent and having high extraction rate. However, non- conventional technique considered as green extraction technique. Some familiar green extraction techniquesare Microwave assisted extraction, ultrasonic assisted extraction, enzyme assisted extraction, pulse electric filedassisted extraction and so on. Microwave assisted extraction and Ultrasonic assisted extraction both thetechnique again confirms the same that the pineapple peel is a good source of natural polyphenol. And extractedpolyphenol is not only solve the environmental issues like waste management but also has lots of potential indifferent or new industries like food industries, pharmaceutical industries, therapeutic industries etc.
