Karakteristik Kurva Isotherm Sorpsi Air Tepung Jagung Instan

Instantiation of flour was expected to affect the equilibrium moisture content which changes the nature of the product. Instant corn flour as raw material of semi-moist foods should be determined of its equilibrium moisture content using the curve of moisture sorption isotherm. Curves of moisture sorption isotherm plays an important role in food drying system, particularly for predicting the shelf life of foods that have low water content. The research was aimed to obtain moisture sorption isotherm curve of instant corn flour from the four varieties of maize, and predicted using the BET (Brunauer-Emmett-Teller) and GAB (Guggenheim-Anderson-deBoer ). Results of the study showed that the moisture sorption isotherm curve of instant corn flour had the sigmoid form (typeII) for all of variety. In most water activities, the moisture sorption isotherm curve of the instant corn flour were relevant to GAB model. BET model was more appropriate to estimate the value of water monolayer (primary bound water) and primary bound water in the instant corn flour; and the value obtained were 3.300 to 3.690 percent; respectively

Pengaruh Konsentrasi Kultur dan Prebiotik Ubi Jalar terhadap Sifat Sari Jagung Manis Probiotik

Sweet corn extract with the addition of lactic acid bacteria can improve its function as probiotic drinks. Sweet potato as a prebiotic is expected to increase the activity of lactic acid bacteria probiotic sweet corn extract. The use of culture in the making of sweet corn extract probiotics will affect the character of the product. The purpose of this study were: (1) to study the effect of culture concentration on characteristics of probiotic sweet corn extract; (2) to study the effect of red sweet potato extract on characteristics of probiotic sweet corn extract; and (3) to determine the best treatment combination between the culture and the concentration of red sweet potato extract in the production of probiotic sweet corn extract; and comparing commercial in the market. Research using a completely randomized design (CRD) with research factor is the concentration of the culture (2, 3, 4, and 5 %) and red sweet potato extract (5, 10, 15, 20 and 25 %). The results showed that the more the concentration of the culture is added, the number of lactic acid bacteria, total acid and viscosity increase; while pH, total dissolved solids, fat and protein concentration decreased. The more sweet potato extract is added, the total dissolved solids and viscosity increased; while the levels of protein and fat decreases. The best treatment combination was at a concentration of 4 % culture and 15 % sweet potato extract. The products have a pH of 3.88, a viscosity of 261.5 cP, lactic acid levels of 0.87 %, 0.05 % fat content, total dissolved solids 19.10 oBrix, and 3.23 % of total protein. Yoghurt is compliant SNI standard yoghurt, except for protein content was lower at 3.23 (SNI according to at least 3.5)

PENGARUH PERENDAMAN JAGUNG DAN SUBSTITUSI TEPUNG TEMPE TERHADAP NILAI GIZI DAN SIFAT SENSORIS BERAS JAGUNG INSTAN

Processing corn into flour will produce byproducts of corn grits as a potential source of instantcorn rice. Modification of seed soaking in the manufacture of corn starch can alter the characteristics of the product. Efforts to increase the protein content in rice can be done in an instant corn flour substitute tempeh. The study aims to determine 1) the influence of soaking corn and soybean meal proportion of chemical and sensory properties of instant corn rice, and 2) determine a combination of soaking corn and the proportion of soybean flour that produces the best chemical and sensory properties of instant corn rice. This research used Randomized Design Group with two factors and three replications. Factor is tested is the process of soaking the seeds in the manufacture of white corn flour; that is, without soaking (P1) and a 24-hour soaking (P2), as well as variations in tempeh flour substitution (T) which consists of five levels, namely 0% (T0); 10 % (T1); 20% (T2); 30% (T3) and 40% (T4). The results showed the best of instant corn rice products is treatment combination of 20% soybean flour substitution and with 24-hour soaking (P2T2). The product has a soluble protein content 1.22% (bk), 2.76% fat content (bk), water content 6.98% (bk); carbohydrate 77.33%, with 2.44 color (yellow), texture 1 , 62 (a bit fluffier), a sense of 1.73 (rather good), corn aroma 2.11 (feeling) and the 2.38 level preferences (likes).Keywords: instant corn rice, soybean flour, soakin

PENGARUH PEMBERIAN MAKANAN TAMBAHAN TERHADAP KONSUMSI ENERGI DAN PROTEIN IBU HAMIL

The objective of this study was to analyze the effect of supplementary foods on pregnant mothers’ energy and protein consumtion. This study was conducted in three sub-districts i.e.: Leuwiliang, Leuwisadeng and Ciampea. The 140 pregnant mothers from these sub-districts were selected for this study. Out of 140 pregnant mothers, 70 pregnant mothers were selected to receive supplementary foods for 6 month and 70 pregnant mothers did not receive any experimental food (control). Product selected as intervention consists of vermicelli, milk, and biscuit. The results of the study showed intervention could improve energy protein consumption of pregnant mother

PEMBERIAN PANGAN YANG DIFORTIFIKASI ZAT MULTI GIZI MIKRO DAN PENGARUHNYA TERHADAP STATUS ANEMIA DAN PERTAMBAHAN BERAT BADAN IBU HAMIL

ABSTRACT. The objetive of this study was to evaluate the effect offeeding with multimicronutrients fortified foods on anemia status and weight gain ofpregnan womrql. This study was carried out in three sub-districts in Bogor, i. e.: Leuwiliang, Leuwisadeng and Ciampea. A double blind randomized control trial was assigned on this study. About 210 pregnant women from these sub-districts were selected for this study and devided into 2groups, (1) 70 pregnant women received fortified foods with multi-micronutrients i.e. iron, iodine, zinc, folic acid, vitamin C, and vitamin A, and (2) 70 pregnant mothers received nonfortifiedfoods, each for 6 mounths. Product chosen as intervention carrier consisted of vermicelli, milk, and biscuit. Distribution ofproducts were carried out every week to thetarget pregnant women. The results of the study showed: (a) intervention could reduce prevalence ofanemia as much as 28% compared with placebo (b) Intervention affected the micronutrients consumption andfulfilled: iron 55,5% RDA, vitamin A 65% RDA, vitamin C 126% RDA, folat 15,3% RDA, zinc 26,7% RDA, iodium 26,3%, (c) intervention didn'tinfluence weight gain during pregnancy

CHARACTERISTICS OF WHITE CORN NOODLE SUBSTITUED BY TEMPEH FLOUR [Karakteristik Mi Jagung Putih dengan Substitusi Tepung Tempe]

Different corn type and processing of corn flour can produce flour with different physical and chemical characteristics. Processing of such flour into noodle will also result in different properties of noodle. While substitution of corn flour with tempeh flour can improve the protein content of the noodle it also impair its sensory characteristics. The objectives of this research were to determine the best combination of corn flour-type, corn flour processing and proportion of corn:tempeh flour to produce the best corn noodles based on physical, chemical and sensory properties. The observed variables of this study were moisture, ash, soluble protein, fat, elongation, colour, flavour, taste, and preferences. The results showed that based on physical, chemical and sensory properties, the best corn noodle could be made from flour made from waxy corn soaked for 24 hours and a ratio of corn:tempeh flour of 80:20. The noodle produced had 12.1% of total protein content, 2.8% of soluble protein, 8.4% of fat, 5.9% of moisture, 3.6% of ash, 69.9% of carbohydrate, 17.6% of elongation, yellow colour, slight flavour of corn/soybean, and 2.6 of preferences.
