Perancangan proses dan peningkatan skala ekstraksi kitin dari kulit udang secara biologis

Abstract

Ekstraksi kitin dari kulit udang dapat dilakukan secara kimiawi maupun biologis. Ekstraksi kitin secara kimiawi dapat menyebabkan hidrolisis polimer sehingga kitin yang dihasilkan viskositasnya rendah. Selain itu, ekstraksi secara kimiawi menghasilkan limbah yang memberi beban pencemaran lingkungan cukup besar. Ekstraksi kitin secara biologis tidak menyebabkan hidrolisis polimer sehingga viskositas kitinnya tinggi. Ekstraksi kitin secara biologis ramah lingkungan dan juga menghasilkan produk samping berupa protein dan kalsium yang mempunyai nilai tambah.

Biologically chitin extraction was conducted by mic robial process for deproteinization and demineralization. Lactobacillus acidophilus FNCC 116 was used for demineralization and Bacillus licheniformis F11.1 for deproteinization. The aim of the experiment was to design the biologi cal extraction process of chitin from shrimp shells and to obtain the best sc aling up criteria for the biological chitin extraction. The result of design of the biologically chitin extraction process from shrimp shells was as follow : The Shrimp shells was ground into pieces of 5 – 10 mm and followed by dem ineralization that was conducted by subsequent batch fermentation.
