Abstract

This study aims to determine the quality characteristics and degrees of chitosan deacetylation of sea cucumber Holothuria scabra skin extracted in different heating time. The reserach was conducted by using experimental method, that was extracting the skin of sea cucumber Holothuria scabra by heating it in extractor NaOH solution for varied time (90, 120 and 150 minutes) to produce chitosan flour. The results showed that the sea cucumber skin was containing of 5,26% water, 17,96% protein, 0,40% fat, 61,11% ash and 17,13% carbohydrate. The yield of chitin flour was 40,40%. It was containing of moisture 5,27%, ash 6,02%, with deacetylation degree of 38,84%. The different of heating time was siginificantly affecting to the quality of the chitosan flour produced. Extracting the skin of sea cucumber by heating it for 150 minutes produced the best quality of chitosan, indicated by the yield of 33,11%, moisture content of 5,96%, ash content of 6,65%,  with deacetylation degree of 69,65%.

Abstract

This research was aimed to determine the effect of iron (Fe3+) concentration on chlorophyll a and b content, carotenoid content and antioxidant capacity of Chlorella sp. The source of Fe3+ obtained from FeSO4.7H2O.  The varying concentration of Fe3+ in Basal media was 0.35, 4.89, 9.44, and 13.99 mg/L. The harvesting of Chlorella sp. was conducted in 3 times: 7th day, 14th day, and 21st day of cultivation periode. The Chlorella sp. was harvested by centrifugation 4800 rpm for 10 minutes. Chlorophyll a b, and carotenoid content were determined by using spectrophotometer with absorbance (Abs) 480, 630, 645, 665 nm and antioxidant capacity was analysed using % DPPH scavenging capacity. Based on the research results shown that the highest amount of Chlorophyll a content (101.43 mg/L) and chlorophyll b content (49.25 mg/L) were resulted in the highest of Fe3+ concentration (13.99 mg/L) for 21 days of cultivation period, the highest carotenoid content (37.41 mg/L) was in 4.89 mg/L of Fe3+ concentration for 21 days of cultivation period, and the highest of % antioxidant capacity (32.74%) was in the lowest of Fe3+ concentration (0.35 mg/L) for 14 days of cultivation period.

Abstract

This research was conducted at the laboratory of Fish Processing Technology, Faculty of fisheries and Marine Science, University of Riau, on January 2014. The research was intended to evaluate the effect of liquid smoke solution which used repeatedly to the smoked catfish (Cryptopterus bicirchis) quality. Liquid smoke which was made from condensate of scull was prepared. The fish was soaked on 80 ml of liquid smoke solution for 30 minutes. Four types of smoked catfish were soaked on 80 ml of liquid smoke solution for 30 minutes repeatedly, and then the smoked catfish was stored in oven for 10 hours. Smoke catfish was evaluated for sensory quality, mositure, pH, acidity and fenol. The result showed that the first soaking of smoked catfish was the best treatment. Sensory quality, moisture, pH, acidity and fenol of smoke catfish was 7,50; 20,01%; 5,87; 2,73% and 5,25% respectively.

Abstract

This research was done to evaluate quality characteristic and consumer acceptance of river carp crackers added with river carp meat. The meat of river carp was taken from fresh river carp in cage aquaculture at Ranah, Kampar regency. Five groups of river carp crackers were made from tapioca flour (53,70%), wheat flour (5,97%), onion (1,79%), salt (1,49%), cake soda (0,30%), water (29,83%), sugar (0,89%) and egg (6,03%); then added the meat of river carp for each concentration 0%, 10%, 20%, 30% and 40%. River carp crackers were evaluated for sensory quality, consumer acceptance, proximate composition and flower power. The result indicated that the cracker was added by 30% river carp meat was most preferable. Moisture, protein, calcium, fat and flower power of the river carp cracker was 3,92%; 17,10%; 5,63mgCa/100g; 18,85% and 57,79% respectively.

Abstract

The purpose of this research was to evaluate the quality characteristic of surimi where made from a mixture of pangasius catfish and snakehead meat. Catfish and snakehead weighing range 800-1.000 gram/fish were obtained from a fish market in Pekanbaru. Catfish and snakehead meat was separated and blended. Five types of surimi were prepared from the two fish meat with a ratio of catfish and snakehead : 100% catfish meat, 100% snakehead meat, 75% catfish meat + 25% snakehead meat, 50% catfish meat + 50% snakehead meat and 25 % catfish meat + 75% snakehead meat. Surimi was leached in a fluid with 0,3% salt, temperature 5-10oC for 15 minutes, filtered, pressed then added 4% sucrosa, 4% sorbitol and 0,3% STTP. Surimi was analized for quality characteristics, gel strength (fold test and bite test), water holding capacity, pH and proximate. The research was designed using RAL and different between treatments were tested by Duncan test. The results showed surimi was prepared ​​from50% catfish meat+ 50% snakehead was the best treatment; the folding test value was 4,2 which was not cracked when folded in half circle; the bite test value was 7,2 strongly elasticity; water holding capacity 37,7%; pH 6,2; protein contant 17,7%; fat contant 0,9% and ash contant 2,1%.
