The objective of the study was to determine the concentation ratio between purple sweet potato flour and wheat flour in order to produce purple sweet potato cookies having particular nutritional content and preffered by consumers. A completely randomized experimental design was applied in this study. One experimental factor which was ratio of purple sweet potato flur and wheat flour consisting five level of treatments, was as signed i,e 100%: 0%, 80:20%, 60%:40%, and 20%: 80% respectively. Variables measured were chemical composition (protein, fat, moisture, anthocyanin content) and sensory properties (colour, taste, texture, overall likeness). Results showed that most variables were influenced by the ratio of sweet potato flour and wheat flour, excluding moisture content. The ratio of 80% sweet potato flour : 20% wheat flour resulted in cookies with good characteristics and mostly preffered by parelists. Anthocyamin content of this particular cookies (80%: 20%) was similar to that of sweet potato flour.  Keywords: cookies, purple sweet potato flour, wheat flour   ABSTRAK  Penelitian ini bertujuan untuk menentukan konsentrasi tepung ubi jalar ungu dan tepung terigu yang tepat untuk menghasilkan kue kering ubi jalar ungu dengan kandungan gizi tertentu dan disukai.

Retnati, Andriani MAM, Fauza G. 2009. The influence of addition of various sweet potatoes (Ipomea batatas) extract to total count of cells and antioxidant activity in yogurt. Biofarmasi 7: 68-76. The aim of this research was to determine the influence of addition of various sweet potatoes extract to the total count of cells and the antioxidant activity in yogurt. Yogurt was made from fresh milk, skim milk, white sweet potato, orange sweet potato, purple sweet potato, and pure culture of Streptococcus thermophilus 0040 and Lactobacillus bulgaricus 0041 in straight MRS agar. Fresh milk, skim milk powder (5%, b/v), and sweet potato extract (10%, v/v) was pasteurized at 90oC for 15 minutes, cooled to the temperature between 40-45oC, inoculated with 2.5% S. thermophilus and L. bulgaricus with a proportion of 1.4:1, and then incubated at a temperature of 40oC for 15 hours. Yogurt without an addition of sweet potato extract was used as control. The parameters measured in this experiment were the total count of cells with TPC (Total Plate Count) method and the antioxidant activity with DPPH (2,2- diphenyl-1-picrylhydrazyl) method. Samples were taken at one hour interval to examine the total count of cells, while the antioxidant activity was collected at three hours interval. The result of each analysis was plotted into graphics which describing the relation of total bacteria and antioxidant activity with fermentation time. ANOVA was employed to analyze the data. If there was a significant difference, it should be followed by Duncan Multiple Range Test (DMRT) at a significance level α=0.05. The result of this research showed that the addition of various sweet potatoes extracts increased the total count of cells and the antioxidant activity in yogurt. The total count of cells showed no significant different for each sample, it meant that the different colors in sweet potato did not influence the total count of cells. However, yogurt with orange and purple sweet potato extract addition had a significant difference on the antioxidant activity with control and yogurt with white sweet potato extract. In conclusion, the difference colors in sweet potato influenced in the antioxidant activity in yogurt significantly. Sweet potato is potential for milk substitute in yogurt production due to oligosaccharide content and antioxidant activity.

Modern food processing technology has resulted in the creations of a new processed purple sweet potato product, one of which is the purple sweet potato ice cream. Ice cream is a frozen food product that are usually consumed as a desert, with main ingredients such as fat, nonfat dry material or nonfat solids, sweeteners, stabilizers, and emulsifiers (CMC). This research was aimed to determine the optimal CMC emulsifier concentration in making sweet potato ice cream. The experimental design used was Completely Randomized Design with four treatments, namely A1 level (control), A2 (0.1% CMC), A3 (0.3% CMC), and A4 (0.5% CMC). The results of this study indicate CMC concentration of 0.5% resulting in ice cream with a good quality, total sugar of 28.1%, fat of 5.67%, protein of 5.51%, total solids of 37.51% and water content of 62.47%. Organoleptic test results showed that with the CMC concentrations of 0.5%, the panelists gave texture attribute values of 3.5 and the degree of preference of 3:28. The purple sweet potato ice cream with CMC concentration of 0.5 percent had a good quality because it fitted with ice cream quality terms according to the SII.

Background: One obstacle in commercial enteral food formulation is the adjustment between nutritional value and rheological characteristics of the product.Objectives: To evaluate the nutritional value and viscosity of polymeric enteral nutrition (PEN) products made from purple sweet potato flour with variations in the level of maltodextrin as a stabilizer.Methods: The completely randomized design was used with four variations of maltodextrin, which was 2.5%, 5%, 7.5%, and 10%. The research was carried out by making purple sweet potato flour, then its proximate composition was measured as a basis for formulating a PEN product that was 200 kcal/200mL, with 60% carbohydrates (120 kcal / 200 mL), 15% protein (30 kcal), and 25% fat (50 kcal). The proximate composition and calorie value of the PEN products were tested. The PEN products were added hot water at a temperature of 90˚C; then, the viscosity was measured at room temperature. The viscosity of two types of commercial enteral nutrition products was measured as a reference.Results: The results showed that there was an effect of maltodextrin level on moisture, fat, and protein contents of PEN products, but there was no effect on calorie values. The viscosity of the PEN products displayed that the higher the maltodextrin level, the higher the viscosity of the product. The viscosity of the PEN products in accordance with the commercial enteral products was the treatment of maltodextrin 5% and 7.5%.Conclusion: There is an effect of maltodextrin as a stabilizer on the nutritional value and viscosity of PEN products based on purple sweet potato flour.

This study was undertaken to analyze the quality of goat milk based cheese particularly its potential high antioxidant content through fortification of goat milk with purple sweet potato extract. A completely randomized design was used to determine the characterization of goat milk based cheese quality through five levels i.e. 0% (A); 2% (B); 4% (C); 6% (D) and 8% w/v (E) of purple sweet potato extract fortification in goat milk. The results showed that the increased level of fortification by purple sweet potato extract in goat milk based cheese significantly increased the pH value of the cheese (P<0.05) where the highest pH was 6.20 at the level of 4%  w/v. Meanwhile, the yield and total of cheese acid were not affected by the fortification. The content of cheese protein significantly decreased (P<0.05) by the increasing level of fortification by purple sweet potato in goat milk. Goat milk-based cheese on the E treatment contained the lowest protein (19.42%). Functional potency of the cheese increased significantly (P<0.05) when the level of fortification was increased. The highest antioxidant content in goat milk based cheese was 114.47 mg/L. GAEAC at 8% w/v level. In conclusion, by increasing fortified goat milk by purple sweet potato extract up to 8% w/v was able to potentially produce cheese containing a high antioxidant.

This study aims to determine the organoleptic test of purple sweet potato jalangkote The analysis of research data is designed with Completely Randomized Design which is arranged with 1 factor that is purple sweet potato (J) : J0 = 50% purple sweet potato flour + 50% wheat flour; J1 = 60% purple sweet potato flour + 40% wheat flour; J2 = 70% purple sweet potato flour + 30% wheat flour; J3 = 80% purple sweet potato flour + 20% flour. Based on the results of organoleptic tests showed that the panelist's assessment of jalangkote sweet potato products gave a very real effect on the color, aroma and texture of jalangkote, Then give no real influence on jalangkote sweet potato flavor purple. The best treatment based on panelist appraisal was treatment of J3 ie 80% purple sweet potato flour + 20% flour in color (4.15) and flavor (4.25). Then the best treatment on the scent (4.50) and texture (4.45) is the treatment of 50% purple sweet potato flour + 50% wheat flour
