Abstract

The dependence of Indonesian people on consumption of wheat flour is high. In addition, wheat flour contains gluten, but not everyone can consume gluten. Indonesia has local food ingredients that can replace wheat flour, one of which is sorghum flour. Making cookies using sorghum flour and almond flour produces gluten-free cookies that are safe for people with gluten intolerants and lactose intolerants. In making cookies, a sweetener is needed, which can be used stevia sugar and crystal coconut sugar. The research aims to: 1) determine the effect of the proportion of sorghum flour and almond flour on the physical and chemical properties of cookies, 2) determine the effect of the proportion of stevia sugar and crystal coconut sugar on the physical and chemical properties of cookies, 3) determine the formulation of sorghum flour and almond flour with the addition of stevia sugar and crystal coconut sugar to produce cookies of the highest quality in terms of physical and chemical properties. The research used factorial randomized block design. The factors studied were the proportion of sorghum flour: almond flour consisted of 3 levels (1: 1; 2: 1; and 3: 1); and the proportion of stevia sugar: crystal coconut sugar consists of 3 levels (2: 1; 1: 1; 1: 2). The variables observed included ash content, moisture content, fat content, dissolved protein content, reducing sugar content and swelling volume. The best treatment is selected using the effectiveness index test. The results showed that the proportion of sorghum flour: almond flour affected the moisture content, ash content, fat content and dissolved protein content of cookies. Comparison of stevia sugar: crystal coconut sugar has an effect on water content, fat content, and reducing sugar content in cookies. The interaction between the two does not affect all variables. Based on chemical and physical variables, the selected treatment was a combination of T1K2 (sorghum 1 flour: almond flour 1 and stevia sugar 1: crystal coconut sugar 1). The physicochemical characteristics of cookies with sorghum flour and almond flour produced from the best treatment combination had a moisture content value of 4.45%, an ash content of 1.04%, a fat content of 33.57%, a dissolved protein content of 1.17%, a reducing sugar content of 5, 91%, and development volume of 60.48%

Abstract

Kimpul is one type of tubers that is high in carbohydrate content so it canbe used as a source of starch. Natural starch generally still has severaldisadvantages. One of method that can be done to overcome theseweaknesses is by modifying cross-linked starch. The objectives of thisstudy are: 1) to know the effect of STPP concentration on chemical andphysical characteristics of modified kimpul starch; 2) to know the effect ofsoaking time on chemical and physical characteristics of modified kimpulstarch; 3) to determine the best combination treatment between STPPconcentration and soaking time on the chemical and physicalcharacteristics of modified kimpul starches. This is an experimentalresearch with Randomized Block Design. The factors studied were theconcentration of sodium trypolyphosphate (1, 2 and 3%) and soaking time(60 and 90 minutes). The variables tested were moisture content, starchcontent, amylose content and calcium oxalate content, brightness, swellingpower, sollubility and its amylographic properties. The results showedthat both STPP concentration factors and soaking time affected themodified chemical and physical characteristics of kimpul starchcrosslinking methods. The chemical and physical characteristics of crossbonded modified kimpul starch increased with STPP concentration andsoaking time used. Modified kimpul starch using 3% STPP concentrationand 90 minutes soaking time had moisture content, starch content, amylosecontent, calcium oxalate content, brightness and high swelling power. Thebest modified kimpul starch is modified kimpul starch using 2% STPPconcentration and 60 minutes soaking time. It has a water content of7,88%, starch content of 63,13%, amylose content of 17,28%, oxalatecontent of 15,84 ppm, swelling power 15,79 g/g, sollubility 11,55%,brightness of 44.13, initial gelatinization temperature of 78,75oC, peakviscosity of 5152.5 cP, hot paste viscosity of 2310,4 cP, breakdownviscosity of 2815 cP, setback viscosity of 1563 cP and cold paste viscosityof 3873,5 cP

Abstract

The prevalence of anemia in pregnant women in Indonesia in 2013 was still high at 37.1%. The impact of anemia on long-term pregnant women causes a decrease in the quality of human resources. Therefore, it is necessary to provide foods with high iron content and which are easily absorbed. Cassava biscuits that have been enriched with Tempe fish flour and fortified Fe are expected to be an alternative to anemia control and pregnant women PEM through a "food-based" approach. The study aims to produce cassava biscuits supplemented with Tempe fish flour and fortified Fe, so that it contains high protein and Fe and has good sensory properties. The experimental design used in the study was Randomized Block Design with 2 factors: type of fortification (F); FeSO4 (F1); NaFeEDTA (F2), and concentration of fortification (K), i.e. 0 ppm (K1); 30 ppm (K2); 45 ppm (K3); 60 ppm (K4); and 75 ppm (K5). The variables observed included water content, Fe content, free fatty acid levels, and peroxide numbers. While sensory properties are texture, fishy smell, metallic taste, and level of preference. The results showed that fortification with 45 ppm FeSO4 was the best treatment that produced biscuits with the best sensory properties. The biscuits have the characteristics of 6.01±0.54% moisture content, 43.69±0.34 ppm db Fe content, 1.17±0.02% free fat acid content, and 9.66±0.76meq O2 / kg peroxide rate. The sensor characteristics are rather crisp texture, less noticeable fishy aroma, less noticeable metal flavor, and rather preferred taste.
