Abstract

The physical, mechanical and degradability properties of bioplastics made from natural and Heat Moisture Treatment (HMT) modified sago starch and their application as packaging for ground coffee were studied. HMT modification increased the amylose content by 4% and decreased the expandability by 7.16%. HMT-modified starch can also reduce the hydrophilicity of bioplastics as indicated by a decrease in WVTR value by 10% and solubility by 59%. The results also showed that bioplastic from natural and HMT-modified sago starch can be degraded on day 9 by 16% and 34%, respectively. Bioplastic from HMT-modified sago starch can be applied as a packaging for ground coffee with the speed of dissolving in hot water for 116 seconds. Keywords: sago starch, Heat Moisture Treatment, ground coffee

Abstract

Lemon Island is a small island in Manokwari Regency, West Papua. The livelihood of the people on Lemon Island is fishing for captured marine fish. Captured sea fish are prone to damage and spoilage during distribution, and the selling price is also low. Thus, it is necessary to educate the community about the need to process fishery products into fish nuggets to increase the shelf life of fish products and provide information to the community about the diversification of processed fish products. In addition, this community service activity is also expected to increase the income of coastal communities in Manokwari Regency, West Papua.

Abstract

The amount of solvent affects the effectiveness of the extraction, so the chemical components are extracted entirely from the plant. This study investigated the best ratio of Akway bark : solvent (ethanol) to produce Akway extract with the highest antioxidant activity. Extraction with the treatment of Akway skin: ethanol ratio of 1:2; 1:4; 1:6 (b/v) was carried out and then the results were tested for total phenolic and flavonoid content and antioxidant activity. The best Akway bark:ethanol ratio was obtained at 1:4 (b/v) ratio with 9.54% extract yield, 289.57 mg GAE/g total phenolic content, 185.47 mg eq quercetin/g total flavonoids. Akway bark extract has potential as a source of antioxidants as indicated by its high antioxidant activity with DPPH free radical scavenging and ferric reducing activity of 50% (IC50) at extract concentrations of 16.59 µg/mL extract and 60.93 µg/mL extract, and carotene bleaching inhibition activity of 85.76%. There are 4 types of phenolic compounds and 4 types of flavonoid compounds identified with the highest percentage of components, namely Pereniporin B (57%).

Abstract

Sago utilization in Papua has not been maximized due to the limited knowledge and abilities of local communities. This technology dissemination activity aims to increase the utilization of local Papuan resources as a substitute for wheat, by applying the equipment and processing methods that have been developed. The method used is tool dissemination and training on sago starch modification and the manufacture of various processed products in the development of business units. Prototype technology disseminated in the form of starch acidification equipment and drying equipment with UV irradiation. The trial results showed that the capacity of the acidification tool produced was 50 kg of wet sago starch (50% moisture content) with an acidification process duration of 3 days. Meanwhile, the capacity of the dryer is 25 kg of wet sago starch (50% moisture content) with a drying time of ± 20 hours. The use of disseminated tools can reduce material contact with contaminant sources resulting in better product quality.

Abstract

Amylosucrase is a transglucosylase enzyme that utilizes sucrose as a substrate to produce α-1,4 glucan (amylose-like polymer). Modification of starch with Amylosucrase can increase the degree of polymerization, degree of crystallinity, heat stability, and increase the proportion of slow digestible starch (SDS) and resistant starch (RS). Thus, Amylosucrase (ASase) modified starch has enormous potential to be developed in the food industry because the consumption of ASase modified starch can improve insulin sensitivity and reduce blood glucose response, making it suitable for consumption by people with Diabetes Mellitus. In addition, consumption of ASase-modified starch also has the potential to prevent obesity and improve blood lipid profile.
