Abstract

The research was aimed to study of making of instant noodle using composite wheat flour, four variety of sweet potato flour and mung bean flour, and to formulate the best  sweet potato variety to make instant noodle. The research had been performed using factorial completely randomized design, with one factor i.e : ratio of wheat composite flour, four variety of sweet potato flour, and mung bean flour (G) : 70%:20%:10%, 70%:20%:10%, 70%:20%:10%, 70%:20%:10%, 70%:15%:15%, 70%:15%:15%, 70%:15%:15%, 70%:15%:15%, 70%:10%:20%, 70%:10%:20%, 70%:10%:20%, 70%:10%:20%. Parameters analyzed where water content, ash content, fat content, fiber content, protein content, carbohydrate content, water absorption, lost of solid on cooking, colour organoleptic score, taste organoleptic value, elasticity organoleptic value, springy organoleptic value. The research showed that the ratio of wheat composite flour, four variety of sweet potato, and mung bean flour had highly significant effect on water content, ash content, fat content, fiber content, water absorption, lost of solid on cooking, colour organoleptic score and taste organoleptic value and had significant effect on protein content and carbohydrate content but had no signifnicant effect on elasticity orgonelptic value and springy organoleptic value. The formulation of 70%:10%:20%  with white sweet potato variety was the best for the making instant noodle. Keyword: Wheat flour, four variet of sweet potato flour, mung bean flour, instant noodle.

Abstract

The aim of this research was to determine the effect of ratio of starfruit with pumpkin pulps and concentration of sodium benzoate on the quality and sensory test of starfruit sauce. This research was using factorial Completely Randomized Design (CRD) with two factors, i.e :ratio of starfruit with pumpkin pulps (P)(90:10%, 85:15%, 80:20%, 75:25%) and concentration of sodium benzoate (S) (0, 0,1, 0,2, 0,3%). The analyzed parameters were water content (%), ash content (%), total microbes (Log CFU/g), total acid (%), vitamin C content (mg/100 g sample), total soluble solid (oBrix), pH,  viscosity, and organoleptic value (colour, aroma, and taste). The result showed that ratio starfruit with pumpkin pulps had highly significant effect on water content (%), total microbes (Log CFU/g),  total acid (%), vitamin C content (mg/100 g sample), total soluble solid (oBrix), pH, viscosity, and organoleptic values (colour, aroma, and taste). The concentration of sodium benzoate had highly significant effect on water content (%), ash content (%), total microbes (Log CFU/g),  total acid (%), vitamin C content (mg/100 g sample), total soluble solid (oBrix), pH, viscosity, and organoleptic value of colour; and had no effect on organoleptic value of aroma and taste and hedonic taste. The interaction of the two factors had highly significant effect on total microbes (Log CFU/g) and had significant effect on organoleptic value of colour. The best treatment which gave the best effect on starfruit sauce was 90:10% of starfruit with pumpkin pulps and 0,2% sodium benzoat. Keyword:Pumpkin, sauce, sodium benzoate, starfruit

Abstract

This study was conducted to determine the effect of drying temperature and concentration of dextrin on the quality of red beet instant drink. This research is using completely randomized design (CRD) with two factors, i. e : drying temperature (S) : (60oC, 70oC, 80oC) and concentration of dextrin (D) : (2%, 4%, 6%, 8%, 10%). The parameters analyzed were yield, water content, ash content, vitamin C content, total soluble solid, solubility, solubility speed, the score value of color and taste, and the hedonic value of flavor and taste. The result showed that drying temperature had highly significant effect on yield, water content, vitamin C content, solubility, solubility speed, the score value of color and taste and the hedonic value of flavor and taste. Concentration of dextrin had highly significant effect on yield, water content, ash content, vitamin C content, total soluble solid, solubility, solubility speed, the score value of color and taste, and the hedonic value of flavor and taste. The interaction between the two factors had highly significant on vitamin C content and the score value of color. Drying temperature of 60oC and concentration dextrin of 10% produced the best quality of red beet instant drink. Keywords :dextrin, drying temperature,instant drink,red beet

Abstract

This research was aimed to know the effect of ratio of red dragon fruit with soursop and agar concentration on the quality of slice jam. This research was conducted using a completely randomized design with two factors, namely the ratio of red dragon fruit with soursop (80%:20%, 60%:40%, 50%:50%, 40%:60, and 20%:80%) and the agar concentration (0,5%, 1%, and 1,5%). The parameters analyzed were the level of moisture content, total soluble solids, vitamin C, crude fiber content, crude pectin content, color, aroma, and texture scores and organoleptic value for color, aroma,taste,and texture. The results showed that the addition of ratio of red dragon with soursop had highly significant effect on the level of moisture content, vitamin C, crude fiber content, crude pectin content, color, texture scores and organoleptic value of color, aroma, taste, and texture. Agar concentration gave highly significant effect on level of moisture content, total soluble solids, fiber content, texture scores, organoleptic value of texture, and had significant effect of organoleptic value of taste. Interaction of the two factors gave significant effect on moisture content. Addition ratio red dragon fruit with soursop (20%:80%) and agar concentration as much as 1,5% produced the best quality of slice jam. Keywords: agar, red dragon, slice jam, soursop

Abstract

This study was aimed to determine the effect of mixed of  garlic extract  with spinach and amount of sugar on the quality of instant germinated soya drink. Complete Randomised Design (CRD) with 2 factors were used: the ratio of garlic and spinach extract (0.5%: 4.5%, 1.0%: 4.0%, 1.5%: 3.5 %, 2.0%: 3.0%) and the amount of sugar (10%, 20%, 30%, 40%). Parameters measured were fat content, water content, protein content, solubility, taste, aroma and color. The results showed that the ratio of garlic extract mix and spinach had a highly significant effect on fat content, water content, protein content, solubility, taste, aroma and color. The effect of  the amount of sugar was differed significantly on fat content, water content, protein content, solubility, taste, aroma and color. Interaction of both factors were significantly  affected the solubility and not significantly effected the fat content, water content, protein content, taste, aroma and color. To produce quality of instant germinated soya drink suggested to used the ratio of garlic and spinach extract 0,5:4,5% and the amount of sugar 10%.

Abstract

The aim of this research was to investigate the effect of mixture of tomato porridge with sweet potato juice and potassium sorbat concentration on the quality of papaya sauce. The research had been performed using factorial completely rendomized design (CRD) with two factors, i.e; mixture of tomato porridge with sweet potato juice (A)=(40:10%), (30:15%), (30:20%), (25:25%) with 50% papaya porridge respectively and potassium sorbat concentration (S)=(0%), (0,1%), (0,2%), (0,3%). Parameters analyzed were moisture content, ash content, total acid, vitamin C content, total soluble solid, viscosity and organoleptik of color, smell, taste. The results showed that mixture of tomato porridge with sweet potato juice had highly significant effect on moisture content, ash content, total acid, vitamin C content, total soluble solid, viscosity and organoleptic value (color, smell, taste). The potassium sorbat concentration had highly significant effect on moisture content, ash content, total acid, vitamin C content, viscosity, and organoleptic values. The intraction of mixture of tomato porridge with sweet potato juice and potassium sorbat concentration had significant effect on total acid and had nosignificant effect on moisture content, ash content, vitamin C content, total soluble solid, viscocity and organileptic values. The (A3)=(30:20%) tomato porridge with sweet potato juice (S2)=(0,1%) potassium sorbat concentration produced better and more acceptable quality of the sauce.
