Pengaruh Waktu Pengukusan Jagung Kuning dan Pemanasan Susu Kedelai Jagung terhadap Sifat Fisikokimia dan Organoleptik Produk

The aim of this research is to study the effects of the time of steaming corn and heating treatment on physicochemical and sensory properties of soy-corn milk. Level of the time of steaming corn were 15 minutes, 30 minutes, and 45 minutes while the method of heating soy-corn milk made with pasteurization and sterilization. The results showed that time of steaming corn affects total sugars, protein content, and colloidal stability of soy-corn milk. The longer time of steaming corn, the increased levels of total sugars, protein content, and colloidal stability of soy-corn milk occured. Heating treatment affects total dissolved solids, total sugar content, viscosity and colloidal stability of soy-corn milk. An open heating method of pasteurization produced higher total dissolved solids, total sugar content, viscosity and colloidal stability than those of sterilization method. The time of steaming corn and heating method of soy-corn milk has no effect on appearance and taste preferences

Pengaruh Substitusi Terigu dengan Tepung Kacang Merah Pregelatinisasi terhadap Sifat Fisikokimia dan Organoleptik Cookies

Substitution of wheat flour with kidney bean flour can be done because both are starch-based materials. The use of kidney bean flour can reduce the use of wheat flour and increase the utilization of local food. The use of pregelatinized kidney bean flour aimed to improve the digestibility values and eliminate the starchy taste in cookies. The aim of this study was to findout the level of substitution wheat flour with pregelatinized kidney bean flour to produce cookies that can still be accepted by the panelists. The level substitution of wheat flour with pregelatinized kidney bean flour used at 0%, 10%, 20%, 30%, 40%, 50%, 60%. The results showed that the difference of substitution of wheat flour with pregelatinized kidney bean flour gave significant effect on the physicochemical properties (moisture content, specific volume, broken power, and color) and sensory properties (preference of favoring of color, broken power, mouthfeel, taste). The higher level substitution of wheat flour with pregelatinized kidney bean flour caused increasing in moisture content and decreasing in specific volume and broken power of cookies. The level substitution of wheat flour with pregelatinized kidney bean flour chosen was 30%, with the moisture content of 2,26%; specific volume 1,54 cm3/g; broken power 2652,98 g/cm; lightness 72,65; redness 8,53; yellowness 29,13; chroma 30,16; hue 73,59; and sensoric score for color, broken power, mouthfeel, taste with each score 4,31; 5,13; 4,87; and 4,79, out of score level 1 to 7 respectively

Pengaruh Konsentrasi Putih Telur Terhadap Sifat Fisikokimia Dan Organoleptik Sari Buah Pala (Myristicafragrans Houtt)

The aim of research was to determine the effect of egg white concentration on physicochemical and sensory properties of nutmeg fruit juice. Randomized Block Design was used in this research with factor namely egg white concentration that consisted of six levels (0%, 1%, 2%, 3%, 4%, 5%). Each level was replicated four times. Parameter tested were pH, titratable acidity, precipitate percentage and sensory (preference of appearance, colour, and taste). Data were be analyzed with Analysis of Variance (ANAVA) (α= 5%). If ANAVA showed a significant effect, it was followed by Duncan's Multiple Range Test (α= 5%). The results showed that egg white concentration significantly affected on pH, titratable acidity and precipitate percentage. The higher egg white concentration, pH value and the percentage of precipitation increased, but titratable acidity decreased. pH value ranged from 3.20- 3.32, titratable acidity value ranged from 71 mL NaOH 0.1N/ 100 mL – 80.92 mL NaOH 0,1N/ 100 mL, the percentage of precipitation ranged from 2.09% - 14.73%. Egg white concentration also significantly affected on the appearance that ranged from 4.71-5.87 (rather do not like – rather like) and taste preferences ranged from 5.09-5.79 (neutral – rather like), but did not significantly affect colour preferences thar ranged from 5.02- 5.33 (neutral – rather like)

Penggunaan Na-cmc Dan Gum Xanthan Untuk Memperbaiki Kualitas Cake Beras Rendah Lemak

The use of Na-CMC need to be combined with xanthan gum hydrocolloid to improve the physical, chemical, and sensory properties of reduced fat rice cake. The research aimed to determine the effect of hydrocolloid concentration (Na-CMC and xanthan gum = 4:1) onphysical, chemical, and sensory properties of reduced fat rice cake. The experimental design was Randomized Block Design with one factor, namely hydrocolloid concentration, which consisted of five levels: 1%, 2%, 3%, 4%, and 5% based on flour weight with five replications. Data were analyzed by Analysis of Variance at α = 5 % to determine the effect of treatment on the physical, chemical, and sensory properties of reduced fat rice cake, and followed by Duncan\u27s Multiple Range Test at α = 5 % to determine differences between treatment levels. The results showed that hydrocolloid concentration gave significant effects on moisture content, specific volume, hardness, cohesiveness, gumminess, chewiness and sensory properties (preference to pore uniformity, ease of chewing, tenderness, taste, and moistness), but didn\u27t give a significant effect on springiness of reduced fat rice cake. Reduced fat rice cake with hydrocolloid concentration of 4% is the most preferred cake by consumers

Pengaruh Lama Penyimpanan Adonan Beku Terhadap Sifat Fisikokimia Dan Organoleptik Puff Pastry Yang Disubstitusi Modified Cassava Flour

The use of frozen dough allow to maintain consistency of the product simultaneously. The formula used mocaf flour 15% as wheat substitution. The objective of this research was to study the effect of storage time of frozen dough on the physicochemical properties and sensory as well as how long the maximum storage of frozen dough that can produce puff pastry that can be accepted by consumers. The experimental design of the study was a randomized block design with single factor, which the storage time of frozen dough consist of five levels (0, 5, 10, 15, and 20 days) with five replication. The parameters tested were moisture content, spesific volume, firmness, and sensory properties in firmness, flakiness, moutfeel (greasy texture), and sugar content. The data were analyzed using ANOVA at α = 5% and followed by DMRT (Duncan's Multiple Range Test) at α = 5% if there was a significant effect of treatment. The frozen storage time significantly reduced water content and specific volume, increased firmness, and panelist acceptance in flakiness. The storage time has no significantly different in sugar content, panelist acceptance in firmness, and mouthfeel (greasy texture)

Karakteristik Fisikokimia dan Organoleptik Sosis Ayam dengan Proporsi Kacang Merah Kukus dan Minyak Kelapa Sawit

Chicken sausage processing did by reducing fat (palm oil) and substituted with fat replacer, fat mimetics type such as steamed red bean. The research aimed to determine the effect of the proportion of steamed red beans and palm oil to physicochemical and sensory characteristics of chicken sausages. The research design used a randomized block design, single factor. The factor is proportion of steamed red bean and palm oil which consists of six levels 0%:100%, 20%:80%, 40%:60%, 60%:40%, 80%:20% and 100%:0% with four times repetition. Increased proportion of steamed red bean and palm oil will increased the moisture content, hardness, gumminess and chewiness, but decreased juiciness, springiness and sensory properties of chicken sausage. The research resulted that proportion of steamed red bean and palm oil do not affect the cohesiveness and adhesiveness of chicken sausages. The proportion of steamed red bean and palm oil which acceptabled was 40%:60
