This research is a part of research on the study of the glycemic index value of biscuit products from mangrove fruit flour with flour from various of tubers. The tubers used in this study were taro and white uwi. The types of mangrove fruit used were pedada and lindur. The starch content in taro tubers and white uwiÂ can be used to make biscuits. It is known that both pedada (Sonneratia caseolaris) and lindur (Bruguiera ghymnorhiza) flour have anti-diabetic and anti-cholesterol properties. This study aims to analyze the characteristics of the biscuits from the formulation of a mixture of mangrove fruit flour with taro and white uwiÂ tubers. This study used a one-factor completely randomized designÂ with 10 levels of treatment, namely the proportion of mangrove fruit flour types of pedada and lindur and taro and white uwi tuber flour with the formula 0: 100, 10:90, and 20: 80. Biscuit product analysis parameters include proximate, organoleptic analysis, and glycemic index. Measurement of the glycemic index value was carried out in vivo using 22 respondents normalÂ human, healthy, with a blood glucoseÂ of 80-100 mg / dL. Blood draws were carried out for 120 minutes at 30-minute intervals. The best biscuits were obtained in the formulation of pedada fruit : taro flour (20: 80), with criteria 84.07%, of yield, Â 3.72% of moisture content, 3.45% of ash, 4.33% of protein, 7.16% of fat, carbohydratesÂ of 81.34%, 64.39% of starch, the dietaryÂ fiber content of 7.69%. Organoleptic test results showed 5.69Â ofÂ color, the taste of 6.68, texture of 6.54, aroma of 7.13. In vivo test results obtained glycemic index values of 51.46, and glycemic load of 12.90

Enzymatic hydrolysis of chitooligosaccharides can be carried out using the chitosanase enzyme. Chitosanase enzyme is a glycosyl hydrolase enzyme that catalyzes the hydrolysis of Î²- 1,4 glycosidic bonds of chitosan to produce low molecular weight chitooligosaccharides. The crab shell (Portunus pelagicus) has the potential to be used as Chito oligosaccharides because the crab shell contains 20-30% chitin. This study aims to determine the effect of chitosanase enzyme concentration and duration of hydrolysis on the characteristics of chitooligosaccharides (COS) from crab shells. This research was conducted using a factorial completely randomized design (CRD) method with two factors and two replications. The factory was enzyme concentration (0.5%, 1%, and 1.5%), factor II was hydrolysis time (3 hours, 4 h, ours and 5 hours). The data were obtained using ANOVA if there was a significant difference, followed by Duncan's Test (DMRT). The results showed that the enzyme concentration (1.0%) and hydrolysis time (4 hours) was the product with the best treatment with a chemical composition of 84.96% yield, 4.83 kDa molecular weight, 86.87% degree of deacetylation and FTIR test results indicate the presence of a functional group, the OH group is obtained at a wavelength of 3624.25 cm-1 and the NH group is at a wavelength of 3404.36 cm-1. Keywords: chitooligosaccharides, chitosanase, hydrolysis,

Synbiotic yoghurt ice cream is a kind of ice cream made from ice cream mix (milk, skim milk and sugar) and purple yam yoghurt as the main ingredient. The inulin, prebiotic compound of purple yam, inulin, can trigger the growth of beneficial bacteria so it would beneficial for the health. The addition of stabilizer, xanthan gum, aims to produce yoghurt ice cream with a soft texture. The aim of this study to determine the effect of proportion of ice cream mix:yoghurt and concentration of xanthan gum on yoghurt ice cream characteristics. This study used a completely randomized design-factorial pattern with two factors and three replications. The factors are proportion of ice cream mix:yoghurt (70:30; 60:40; 50:50) and concentration of xanthan gum (0.1%; 0.2%; 0.3.%). The observed data were analyzed using ANOVA, followed by DMRT test at 5% level if there were significant differences. The study revealed that the best treatment, based on physicochemical properties of ice cream, is the proportion of ice cream mix:yoghurt (60:40) and xanthan gum concentration (0.2%) with total LAB of 8.55 log CFU/ml; overrun 27.69%; melting time 13.51 min/10 gr; total dissolved solids 31.00 OBrix; viscosity 517.00 mPas.

The objectives of this research were to produce crackers based on sorghum modified flour and to predict its shelf life using a critical moisture approach. The research was conducted in two stages. The first stage was to determine the best crackers of nine formulations. The second stage was to predict the shelf life of the best crackers formulation by using a critical moisture content approach. The best crackers were produced from a mixture of 50% sorghum modified flour, 50% wheat flour and 25% margarine. The products had a puffing ratio of 38,04 %, and hardness of 28.86 N. The moisture sorption isotherm curve of sorghum modified flour crackers could be described using a Hasley model. Using the critical moisture approach, sorghum modified flour crackers packaged in a metalized plastic and stored at 30°C and stored at 84% relative humidity, the product shelf life would be 207 days.

Coliform, Escherichia coli and Salmonella sp. are bacterial pathogen that causes foodborne disease which often contaminates food that is harmful to human health. The sale of meatballs without packaging accompanied by poor hygiene and environmental sanitation conditions has a high potential for contamination by Coliform, Escherichia coli and Salmonella sp. The purpose of this study was to identify the contamination of Coliform, Escherichia coli and Salmonella sp in bulk and packaged meatballs sold at PD Pasar Surya in the East Surabaya Region and to determine the relationship between the hygiene and sanitation of traders on the level of bacterial contamination, Coliform contamination, Escherichia coli and Salmonella sp in bulk and packaged meatballs. This research is a cross sectional study and the sample was taken by purposive sampling method. The relationship between hygiene and sanitation of traders with microbiological quality of bulk meatballs and packaged meatballs using Chi Square. The results showed that the level of total bacterial contamination was higher in bulk meatballs (66.6%) compared to packaged meatballs (40%), Total Coliform bulk meatballs were 60% higher than packaged meatballs (40%), Escherichia coli meatballs Bulk meat (40%) is higher than packaged meatballs (20%), Salmonella sp in bulk meatballs (33.3%) is higher than packaged meatballs (40%). There is a significant relationship between the hygiene and sanitation of traders and the level of bacterial contamination, Coliform, Escherichia coli and Salmonella sp.

Indonesia merupakan negara yang memiliki potensi signifikan dalam produksi mikroalga, namun pemanfaatannya masih sangat terbatas. Terdapat banyak penelitian terbarukan yang menyatakan bahwa banyak jenis mikroalga yang mampu menghasilkan metabolit berupa asam lemak omega-3 DHA dan EPA dengan konsentrasi tinggi, yang juga dapat menurunkan biaya produksinya. Thraustochytrids merupakan mikroalga penghasil lipid yang tumbuh di habitat laut dan bakau. Dalam pertumbuhannya, Thraustochytrids bersifat heterotrof dimana sumber karbon yang digunakan adalah glukosa. Pisang raja dapat menjadi sumber karbon yang menjanjikan bagi pertumbuhan Thraustochytrids terkait dengan kandungan glukosanya yang mencapai 18,55% ketika dalam keadaan overripe (limbah). Pada penelitian ini dilakukan studi terkait produksi biomassa kering mikroalga Thraustochytrids yang diisolasi dari daun mangrove (Rhizophora apiculata). Pada lama waktu fermentasi yaitu 5 dan 7 hari, dan konsentrasi sari pisang raja overripe pada 0%, 25%, 50%, 75%, dan 100% diperoleh berat biomassa kering yang berbeda. Berat kering 3,9 g/L pada konsentrasi sari pisang 50% di hari ke-7 fermentasi serupa dengan glukosa murni (0% sari pisang) yaitu sebesar 3,95 g/L di hari yang sama. Biomassa kering yang dihasilkan ke depannya dapat diekstrak lebih lanjut untuk menghasilkan asam lemak tak jenuh seperti DHA dan EPA.
