Abstract

The aim of this study was to determine the effect of variaus concentration of wax emulsion onthe shelf life of red dragon fruit (Hylocereus polyrhizus). This study was done at the Laboratory ofAnalysis of Agricultural Products, Faculty of Agriculture, University of Riau. The design used in thestudy was completely randomized design (CRD) with 5 treatments and 4 replications. Treatments wereperformed during the study were L1: No wax emulsion; L2: Application of 2% wax emulsion; L3:Application of 4% wax emulsion; L4: Application of 6% wax emulsion; L5: Application of 8% waxemulsion. The data formed were statistically analyzed with analysis of variance. Parameter absorvedwere total dissolved solid, weight shrinkage, respiration rate and organoleptic tests including skinand flesh colors, flavor and aroma. Use of wax emulsion significantly affected the weight, moisturecontent, textue, flash and skin colors and teste, but did not significantly influence the dissolved totalsolid, respiration rate, and aroma of rad dragon fruit. The best treatment found when 6% of waxemulsion applied.Key words: dragon fruit, wax, combined

Abstract

The purpose of this study was to determine the effect of using sago starch, tempe flour and purple sweet potatoflour to the characteristics physicochemical and sensory of the cookies and meet the quality standard ofcookies (SNI 01-2973-1992). The research used a Completely Randomized Design (CRD) with five treatmentand four replications. The treatment in this study were K1 (sago starch 100%), K2 (sago starch 60%, tempehflour 20%, purple sweet potato flour 20%), K3 (sago starch 50%, tempeh flour 25%, purple sweet potato flour25%), K4 (sago starch 40%, tempeh flour 30%, purple sweet potato flour 30%), K5 (sago starch 30%, tempehflour 35%, purple sweet potato flour 35%). The data obtained were statistically analyzed using analysis ofvariance (Anova). If F count is greater than or equal to F table, then conduted a further test with Duncan?sNew Multiple Range Test (DNMRT) at the level of 5%. The results showed that the treatment significantlyeffect to the moisture content, ash content, protein content, analysis texture, descriptive sensory assessmentand hedonic sensory assessment and non significant on the overall hedonic ratings. The best cookies in thisresearch is was K3 with has 2.95% of moisture content, 1.14% of ash content, 8.86% of protein content 4.30kgf of texture, coloured purple, sweet scent purple sweet potato, slightly brittle texture and having sweetness.

Abstract

The objective of the research was to determine the influence of dosage and storage ripening of Calcium Carbide in degreening process of Bangkinang citrus. The research was set up in Complete Randomized Design with four calcium carbide dosage (20, 25, 50, 75 g/kg) on three duration of storage ripening (3, 4, and 5 days). The result of this research concluded that the best treatment was the degreening process with 50 and 70 g/kg calcium carbide dosage and 4 to 5 days storage ripening. Physical and chemical analysis af citrus from this treatment resulted in 5,083-6,2500 Brik total soluble solid and 0,043-0,77% total acid, while organoleptic test showed average hedonic score of 5 and 4,8-5 (both were extremely like), for colour and flavor, respectively. Key words : Calcium carbide, degreening, citrus.

Abstract

The purpose of this research was to estimate the shelf life of wajik that is packed with oil paper and tapioca edible film. Estimation of shelf life using the acceleration method by storing wajik for 30 days at three different temperatures, there are temperatures of 30°C, 35°C, and 40°C. The parameters observed during the storage process were sensory assessments of rancidity and thiobarbituric acid (TBA) values of wajik. Data were analyzed using linear regression and the equations obtained were used to calculate the shelf life of wajik at normal temperature, which is 29°C. The wajik shelf life packed with oil paper based on rancidity sensory test is 29.787 days on the zero order reaction with the regression equation y = -2225.17x + 5.0060, with an activation energy value (Ea) of 4419.188 kal.mol-1, and the value of quality degradation (k) is 0.094 quality unit per day, while the wajik shelf life based on the TBA value test is 27.294 days on the first order reaction with the regression equation y = -3164.10x + 6.7644, with an activation energy value (Ea) of 6283.903 kal.mol-1, and the value of quality degradation (k) is 0.022 quality unit per day. The wajik shelf life packed with tapioca edible film based on rancidity sensory test was 45.455 days on the zero order reaction with the regression equation y = -3444.46x + 8.6946, with an activation energy value (Ea) of 6840.698 kal.mol-1, and the value of quality degradation (k) is 0.066 quality unit per day, the wajik shelf life based on the test TBA value is 32.234 days on the first order reaction with the regression equation y = -1086.80x - 0.0582, with the activation energy value (Ea) of 2158,385 kal.mol-1, and the value of quality degradation (k) is 0.026 quality unit per day. Keywords: Edible film, oil paper, shelf life, wajik.

Abstract

The processing of mangosteen rind is still less than optimal, so one of processing mangosteen rind is making herbal tea. The purpose of research is drying mangosteen rind with best quality and knowing the acceptance of panelists from herbal tea of mangosteen rind. Research conducted using a Completely Randomized Design (CRD) with 4 treatments and 4 replications. Each treatment is using drying for 3 hours at different temperatures, namely 75°C, 80°C, 85°C and 90°C. Parameters measured were water content, ash content, crude fiber, antioxidants, toxicity and organoleptic. The result showed the drying temperature significantly affect the water content, crude fiber, organoleptic and not significantly to ash content. The best treatment is drying at 85 ° C with a water content value 7.98; 4,129 ash content; crude fiber 7863; antioxidant 3.95 × 10-34; toxicity of 34.67 and 0.92 overall acceptance. Keywords: mangosteen, drying temperature, mangosteen rind, herbal tea

Abstract

The study aimed to obtain the proper formulation in the manufacture of white oyster mushroom meatballs. The research was carried out experimentally using completely randomized design (CRD) with five treatments, namely : JP1 (95% White Oyster Mushroom : 5% Catfish), JP2 (90% White Oyster Mushrooms : 10% Catfish), JP3 (85% White Oyster Mushroom : 15% catfish), JP4 (80% White Oyster mushrooms : 20% catfish), JP5 (75% White Oyster mushrooms : 25% catfish). The results showed that the combination of oyster mushroom with catfish significantly effect on the moisture content, ash content, fat content, flavor and texture, on organoleptic but did not significantly affect the color, flavor and overall acceptance. The best combination was JP4 (80% White Oyster Mushroom : Catfish 20%) which content 75,61% water, 2,01% ash, 0.65% fat, grayish white color, the aroma of fish,distinctive flavor fish balls, chewy texture and overall assessment by panelists preferred meatballs Keywords:Meatballs, WhiteOyster Mushrooms and Catfish

Abstract

Transparent soap is produced by reaction between natrium or potassium with oil vegetarian or oil animals, transparent soap manufacturing in Indonesia have not optimals and still difficult to find in the market. Addition of colour and deodorant aim to to more upgrade esthetics and assess to sell of society. One of reason of election of the deodorant and colour because more interesting and impress by experience. Existence soap in the middle of society of vital importance in assessment by organoleptik, cause of assessment of organoleptik can improve, repair product , looking after quality and know level of panelist identification. Intention of this research is acceptance of panelist to nature of organoleptik of transparent soap which formulation between palm oil with addition of colourant and deodorant.   The studies were conducted with organoleptic test. This research used completely randomized design with six treatments and twenty replications. Data obtained were treated by the analysis of variance followed by duncan test. The test hedonik, addition colours and perfumes of transparent soap give real influence to colour and perfume, but give influence is not real to a lot of spume, tekstur, and assessment is overall. Colour which prefer that is red colour with trawberry perfume, perfume which prefer that is treatment blue colour green tea perfume.   Keyword: transparent soaps, colour soap, perfume soap, and vegetables oil soap.
