Indonesia is one of the biggest central distributions of sago starch. There are some characteristics of sago starch which make it difficult to use in variation of foods. In this study, resistant starch type III (RS3) was produced from sago starch by using lintnerization-autoclaving (LA). Physicochemical characterizations of RS3 were compared by native sago starch (NA), hydrolyzed starch by distilled water (DW) and lintnerized starch (L). Amylose content decreased after hydrolyzed by DW and L, but increasing by using LA. Protein and fat contents decreased after hydrolysis, but crude fiber content increasing, the highest value was obtained lintnerized-autoclaved starch. Lintnerized-autoclaved starch has more compact and rigid structure. The RVA viscosity, swelling power and water holding capacity values reduced after all treatments. Oil in water emulsions were also analyzed by mixture of RS3 and emulsifier (casein or SPI). Viscosities of emulsions from RS casein were lower than those of RS-SPI. Emulsion capacity and emulsion stability values were better gotten using RS-SPI than RS-casein. The highest of emulsion capacity was obtained 11.33%. For storage period, the lowest peroxide and anisidine values of mixture RS-emulsifier were resulted from 5% emulsifier + 5% RS + 5% fish oil.

Papua and West Papua Province have the large potential of sago palm (Metroxylon sagu), however, until now the production and utilization is very low compared with its potential. This is because of most farmers in this area still use traditional method in processing sago.  The traditional method is labour intensive and time consuming process.  Sago farmers in this area still apply traditional ways to process sago starch due to the lack of processing machines. The objective of this research was to conduct field testing of sago processing  machine produced by Agroindustry Machinery Workshop of Papua University. The machines that have been tested consist of cylinder type sago rasping machine and stirrer rotary blade sago starch extraction machine. The machine’s performance under field condition was evaluated by measuring parameters (a) rasping capacity, (b) extraction capacity, (c) starch percentage, (d) starch yield and (e) starch loss in waste. Results showed that all parts of the machine are functioning properly and farmers can easily operate the machine.  The performances of the machines under field condition were (a) rasping capacity 1,159. 8 kg/hour, (b) extraction capacity 243.8 kg/hour, (c) starch percentage 38.26 %, (d) starch yield 93 kg/hour   and (e) starch loss in waste 1.03 %.   Keywords: cylinder type, field test, rasping machine, sago processing, starch percentage

Starch tartarate nanoparticles were prepared by esterification reaction between native sago starch (Metroxylon sagu) and tartaric acid using dimethyl sulphoxide (DMSO) as a solvent and 2-dimethylamino pyridine (DMAP) as a catalyst at 100°C. The substitution of tartaric acid onto native sago starch was confirmed by the FTIR spectra which showed the presence of carbonyl group absorption band of tartarate ester. The solubility of the as-synthesized starch tartarate nanoparticles was observed to increase linearly with increase in the degrees of substitution. Under optimized synthesis conditions, starch tartarate nanoparticles of mean particle sizes which ranged from 200 nm to 300 nm were produced.

And Chemical Properties

The purpose of this research was to analyze the physical and chemical properties of sago starch edible film (Metroxylon sagu Rottb) as capsule shells material. The research was started with the extraction of the rumbia starch, and was followed with the production of edible film added with modified carrageenan concentrations (20% and 30% w/w) to the main compound. Organoleptic test showed that the color and odor of the films were normal. Water content of wet sago and dry sago was 12.55%, and 5.38%, respectively. Although the addition of carrageenan increased the water content but still corresponded with SNI gelatin quality standard with a maximum of water content of 16%. The ash content of fresh sago and dry sago was 0.36% and 1.09%, respectively, and the content increased significantly with the addition of carrageenan. The pH of all varied samples was 5.5 – 7.0, and the pH was in accordance with SNI. Meanwhile, the heavy metal content of the samples measured by means of AAS was negative. Based on viscosity testing withBrookfield method, high carrageenan concentration led to low viscosit. tensile strength test based on ASTM D 882-2002 gave positive results for dry sago (21.05 kg/cm2) whereas fresh sago with modified 20% and 30% carrageenan had tensile strength of 5.33 kg/cm2 and 18.18 kg/cm2, respectively. The results showed that sago starch had the potential as a raw material for producing soft capsules by modified composition to enhance physical and mechanical properties in order to meet the quality standard of edible film.

A sago starch- based (Metroxylon sagu) edible coating with sago powder as a filler and glycerol as a plasticizer has been made.This research is expected to provide information about microbial sensitivity towards the sago starch- based edible coating which is eco-friendly and safe to be used. Requirements to determine food quality refers to the role of E.coli as a toxicity indicator to cause food damage. Toxicity testing of E. coli toward sago starch-based coating was conducted by using Kirby Bauer method. A standardized agar-disc paper diffusion procedure is one way to to determine antibiotic resistancy of bacteria. Bacterial resistancy toward antibiotics is determined by the diameter of inhibit zone formed. Microorganisms cultures requires media that contain nutrients and appropriate environment such as Nutrient Agar (NA). Based on E. coli toxicity testing conducted to the sago starch-based edible coating in 370C temperature and 48 hours of incubation, it is found that the edible coated has not anticeptic activity toward Escherichia coli because the inhibit zone is not formed on the sago starch- based coating. Therefore, the edible coating which has been made is healthy to be consumed.
