Abstract

The aimed of this research was to investigate the methode of ozone application for maintaining the quality of Lombok swamp cabbage cultivated on two different area. The main focus of this research was to identify the heavy metal and pathogen contamination on swamp cabbage those were cultivated in different area of Jangkok riverside. The experiments were conducted in laboratory of food microbiology of faculty of food science and technology and laboratory analitical chemistry of science faculty, university of Mataram. The experiments were arranged with completely randomized disign. The treatment design was factorial with three replications. The first factor was the length of rinsing with ozonized water: 3, 5, and 7 minutes, and the other was swamp cabbage cultivation area: upper stream and down stream area of riversides. Parameter for observation were moisture, ash, Pb content, weight loss, color, texture, appearence and total bacteria especially Escherichia coli of swamp cabbage samples. The result showed that the longer time of rinsing with ozonized water, the lower Pb content of swamp cabbage. The Pb content of swamp cabbage of upper stream area reduced significantly, however the Pb content was higher than that of lower stream. The total bacteria of swamp cabbage of lower stream was higher than that of upper stream. Rinsing swamp cabbage for 7 minutes enable total bacteria contaminant reduce significantly, and effective for swamp cabbage with lower Pb content.

Abstract

Banana slice (sale) is a type of food made from bananas preserved by drying. The purpose of this reserch was to determine the concentration of sodium metabisulphite and drying methods appropriate to maintain the quality of bananas sale. The experimental design of this reserch is a completely randomized design (CRD) with factorial experiment consisting of two factors: the method of drying (P1 = drying, P2 = solar drying) and the concentration of sodium metabisulphite (K1 = 1000 ppm, K2 = 1500 ppm , K3 = 2000 ppm) to obtain 6 treatment combinations, namely: P1K1, P1K2, P1K3, P2K1, P2K2, P2K3. Each combination is repeated three times to obtain 18 units experiment. Parameters studied were the chemical properties (water content, vitamin C and sugar reduction), organoleptic (taste, color, aroma and texture) and physical color (colorimeter). Adding metabisulfite concentration (P) and the method of drying (K) gives a significantly different influence on water content, vitamin C, reducing sugar content, color and physical hedonic flavor, color and aroma of banana slice (sale). But for texture hedonic no significant effect.sun drying method of drying showed better results than the solar drying and more of the addition metabisulfite will improve the quality of banana slice (sale). The best treatment is P1K3 (drying to 2000 ppm metabisulfite). Which has a low water content (19:01%), the highest vitamin C (5:40 mg / 100g), the highest reduction sugar (2:57%), hedonic color (3.90) and highest brightness (86.22 ° Hue) Keywords : banana slice (sale), sun drying, solar dryer, sodium metabisulfite.

Abstract

This reasearch aim was to investigate the appropriate formulation and method of producing the modified cassava flour (MCF) sweet bread. The experiment was conducted in laboratory and arranged with completely randomized design of factorial with three replications. The treatments variabel included the proportion of 10, 20 and 30% MCF based on the total flour in formulation and three different methods of dough preparation. The straight dough, sponge and dough method and no time dough, respectively were the methods of dough preparation. The bread quality parameters were physical characteristics such as color, crumb structure, loaf volume, organoleptics such as taste, flavor, and chemical composition such as ash, protein, lipid and sugar content. Data were analyzed with analyses of variance and post hoc test with Least Significant Difference at the same level of sigificance of 5 percent. The result showed that the methods of dough preparation gave affect on the organoleptic characteristic, but they did not show affect on the physical and chemical composition of the bread quality. MCF proportion in formulation found their affect on moisture and protein content, however on others parameter their affect were not found. The higher proportion of MCF in formulation, the higher the moisture content of the bread. In contrast to the protein content of the bread, the higher the proportion of MCF in formulation, the lower the protein content. The MCF sweet bread produced with straight dough method and 20% of MCF in formulation had the best quality parameter of physical, organoleptic and chemical composition and met the Indonesia quality standard of sweet bread, except the protein content. Key words: bread, formulation, modified cassava flour, dough methods ABSTRAK Penelitian ini bertujuan untuk mengetahui formulasi dan metode pembuatan adonan yang menghasilkan mutu roti manis berbahan baku mocaf terbaik.
