The effect of the antarctic krill (Euphausia superba) chitin as a dietary fiber on the availability of protein and minerals (Ca, Mg and P) was studied in growing rats fed diets containing 5% krill chitin, lobster (Panulirus gracilis) chitin or cellulose for 10 days. The chitins were prepared by the modified Hackman's method (the treatment with 1 N HCl and 1 N NaOH and the following extraction by acetone) from the frozen blocks of raw krill or the shells of boiled and frozen lobster.<BR>Total nitrogen and ash contents of both the purified chitins were 6.82% and 0.1%, respectively.<BR>The settling volume in water (SV, ml/g) of the examined dietary fibers was 35.0 for krill chitin, 12.0 for lobster chitin and 3.4 for cellulose.<BR>There were no differences in the net protein ratio and retention rate of dietary nitrogen (excluding chitin nitrogen), between krill chitin and the other two dietary fibers.<BR>The most deteriorating effect of the dietary fibers on the mineral balances was observed for krill chitin, followed by lobster chitin. High correlation, |r|=0.707-0.943 (p<0.01), was found between each of the mineral balances (fecal, urinary and total excretion, apparent digestibility, retention and retention rate of the three minerals except urinary P excretion) and the log SV of each dietary fiber. These results show that the effect of krill chitin as a dietary fiber on the bioavailability of minerals can be partly ascribed to its high SV.
