Abstract

Cookies are processed cakes made from wheat flour. However, currently the need for flour is mostly met with import activities, so there needs to be an effort to reduce dependence on the use of wheat flour. One of the local food resources that can be used as an alternative to flour is cocoyams flour (Xanthosoma sagittifolium) which was modified by the fermentation process using the starter Lactobacillus plantarum to improve product texture. Tapioca can also be used as a substitute for wheat flour in making cookies, while the formation of texture can be helped by the addition of margarine. This study aimed to determine the effect of the proportion of cocoyams flour: tapioca flour and the addition of margarine to the characteristics of cookies. This research used factorial completely randomized design with two factors. The first Factor is proportion of modification cocoyams flour and   tapioca (50:50, 60:40, and 70:30). The second factor in the form of concentration addition of margarine (50%, 60%, 70%). The results showed that the best treatment was the proportion of modification cocoyams and tapioca flour (70:30) and the addition of 50% margarine which produced cookies with criteria of water content of 3.95%, fat content of 29.15%, crude fiber of 3.29%, fracture strength of 11.17 N, yield of 55.95%, and organoleptic test results with the number of ranks of preference level for crispness/texture of 139, aroma 110.5, color 106 and taste 133.8

Abstract

Zanthoxylum acanthopodium, locally known as Andaliman, is exotic spices which grown in North Sumatera. Several investigation shown that the special taste and aroma comes from pericarp of Andaliman. However, the pericarp of Andaliman is easily degraded. The proper postharvest handling of Andaliman is necessary to preserve fresh Andaliman for long time. Previously, Andaliman has been preserved in packaging under room temperature storage. Further investigation of Andaliman preservation in packaging under low temperature storage would help reduces the postharvest losses. In this study, the physical changes of Andaliman in various packaging under low-temperature storage were observed. The results shown that within 2 days, the pericarp of Andaliman in paper packaging was shrunk, similarly found in control without packaging. Meanwhile, the pericarp of Andaliman in aluminum foil and PP plastic were found normal in day 3. This result indicated that in low-temperature, Andaliman in Aluminum foil was recommended for best postharvest handling.

Abstract

The main problem encountered in the production of tempeh was its raw material, namely soybeans dominated by soybean supplied from other countries, mainly dominated by imported products from the United States. The majority of tempeh craftsmen's perception is that imported soybeans are superior to local soybeans. This is of course unfortunate because it will further aggravate the competitiveness of local soybeans. This research was conducted to explore the advantages of local soybeans, especially from the physico-chemical aspects of imported soybeans. The research objective was to map the physico-chemical properties of local and imported soybeans as raw material for tempeh. One factor trial design was used, with soybean varieties (4 local and 1 imported) as a factor. Variables observed included: antioxidant, bulk density, swelling power, plant quality, seed size, WAI, WSI, protein, yield, and density. The results obtained: 1) antioxidant : Devon 1 imported soybeans, 2) bulk density: fourth of local soybeans = imported soybeans, 3) swelling power : Argomulyo = imported soybeans, 4) quality of  cooking: fourth of  local soybeans imported soybeans, 5) seed size : Grobogan and Argomulyo imports, 6) WAI:  Argomulyo and Demas imported soybeans, 7) WSI: Devon = imported soybeans, 8) protein: Grobogan and Detam imported soybeans, 9) density:  Bromo imported soybeans, 10) extraction value: Anjasmoro, Argomulyo, and Grobogan imported soybeans.

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

Inulin is one of many functional food components that becomes a trend nowadays. Inulin can be found in the stems and roots/tubers of plants. Yellow sweet potato (Ipomea batatas L.) is a widespread species of sweet potato with abundant availabilty in Indonesia, where it is exploited only as a source of carbohydrate. From the previous study, it was stated that sweet potato can be used as an alternative resource of inulin besides dahlia and Dioscorea spp. tubers. This study aimed at extracting and isolating inulin from aqueous extract of yellow sweet potato with 3 different ratio (1:1, 1:2, 1:3) and 3 different time (6, 12, 18 hours) to determine its effect on the yield of inulin. After preparation of extracts, crude inulin was precipitated in 96% ethanol. The free reducing sugar from sweet potato flour was tested using Dinitrosalisylic Acid Method (DNS). After precipitation, inulin powder was obtained by an overnight drying process using oven at 60ºC and characterized by color, solubility, water absorption, moisture content and ash content. Its inulin structure was analyzed and confirmed by Fourier Transformed Infrared (FT-IR) spectroscopy. The results showed that different ethanol ratio and precipitating time has effect on the yield of inulin. The highest yield of inulin were 8.80% obtained from solvent ratio 1:3 with 18 hours of precipitating time. It can be concluded that yield of inulin were affected by solvent ratio, precipitating time and degree of polymerization (DP). Higher solvent ratio and precipitating time could obtain higher yield of inulin.
