Deskripsi Buku

Maggots are larvae of the BSF fly type which have potential as raw material for chitosan because they contain chitin The production of chitin into chitosan goes through the deacetylation stage using a strong base with a high concentration causing the neutralization process to take a long time and require a lot of distilled water For time and cost efficiency acid is used in the neutralization process The aim of the research was to determine the effect of the type and concentration of acid on the degree of chitosan deacetylation Chitosan is made through deproteination demineralization depigmentation and deacetylation stages The deacetylation stage is neutralized with two types of acid namely acetic acid and hydrochloric acid with a concentration of 1 5 3 and 6 The results was observed 3 175 to 6 558 3 204 to 5 833 2 714 to 4 617 11 50 to 15 33 and 53 04 to 71 22 for water content ash content total nitrogen level yield and deacetylation degree respectively The best treatment was combination of 6 hydrochloric acid with a water content of 3 17 ash content of 3 20 total nitrogen content of 2 71 and degree of deacetylation of 71 22 The procedure for making chitosan in previous research was without heating or soaking using room temperature and using neutralization using distilled water so it tookMaggots are larvae of the BSF fly type which have potential as raw material for chitosan because they contain chitin The production of chitin into chitosan goes through the deacetylation stage using a strong base with a high concentration causing the neutralization process to take a long time and require a ...lot of distilled water For time and cost efficiency acid is used in the neutralization process The aim of the research was to determine the effect of the type and concentration of acid on the degree of chitosan deacetylation Chitosan is made through deproteination demineralization depigmentation and deacetylation stages The deacetylation stage is neutralized with two types of acid namely acetic acid and hydrochloric acid with a concentration of 1 5 3 and 6 The results was observed 3 175 to 6 558 3 204 to 5 833 2 714 to 4 617 11 50 to 15 33 and 53 04 to 71 22 for water content ash content total nitrogen level yield and deacetylation degree respectively The best treatment was combination of 6 hydrochloric acid with a water content of 3 17 ash content of 3 20 total nitrogen content of 2 71 and degree of deacetylation of 71 22 The procedure for making chitosan in previous research was without heating or soaking using room temperature and using neutralization using distilled water so it took
