Abstract

The characteristics of flour much determine the quality of food products. Maize starch has several limitations to be developed into food products. Hence, to expand its use in food production, the starch needs to be modified. Modification of the starch can be done through the fermentation process. This modification is expected to change its physico-chemical aspects and functional properties. Some lactic acid bacteria (including L. bulgaricus and L.casei) are capable of degrading the corn cell wall,resulting in the starch granules to come out of the cell which eases the grinding process. L. bulgaricus and L. casei also can degrade starch contained in the growth medium into simple sugars, degrade proteins, and peptides into amino acids (Ganzle et al., 2008). The modified maize starch is also expected to be a proper substitution of regular flour in food products. The purpose of the research is to examine the quality of the modified starch through fermentation. The results showed that thefermentation time and concentration of bacteria dramatically affect the physical results where fermented corn was whiter and slightly acidic and chemically decreased the pH of corn flour to 4.5 and was relatively stable at 48 hours fermentation with a concentration of 4% and 6 %. The bestmodified chemical properties of local white corn are 36 hours fermentation with a concentration of 2% lactobacillus casei with a total protein value of 8.7%.

Abstract

This research has been conducted in the Laboratory of Food Technology at the State Agricultural Polytechnic of Kupang, in March to September 2019. The purpose of this study is to examine the effect of blanching time on changes in the nutritional value of moringa leaf micronutrients. This study was designed using a Completely Randomized Design (CRD) with one factorial, namely the length of time Blanshing (B): B0 = without blanching; B1 = blanching 3 minutes; B2 = blanching 5 minutes and B3 = blanching 7 minutes. Each treatment was repeated 4 times to obtain 16 experimental units. Variables observed included Micro nutrients namely Vitamin C, Beta Carotene and Vitamin B2 Riboflavin and analyzed using HPLC. The results showed that blanching time greatly affected the decrease in micronutrients such as beta carotene, vitamin B2 and vitamin C. Vitamins C and  B2, beta carotene, of moringa leaf flour decreased with increasing blanching time. Vitamins C in moringa leaf flour without blanching is 94.98 mg / 100 g decreases after blanching 3 minutes to 33.63 mg / 100 g, and on blanching 5 minutes it becomes 9.64 g / 100 g and on blanching 7 minutes becomes 3 , 44 mg / 100 g. Vitamins B2 (riboflavin) Moringa leaf flour without blanching by 15.29 mg / 100 g decreases after blanching 3 minutes to 13.07 mg / 100 g, and on blanching 5 minutes becomes 13.49 mg / 100 g and on blanching 7 minutes to 8.68 mg / 100 g. Beta caroteness of Moringa leaf flour without blanching was 303.68 mg / kg decreased after blanching 3 minutes to 300.58 mg / kg, and on blanching 5 minutes it became 299.33 g / kg and in blanching 7 minutes it became 234.65 mg / kg. Moringa leaf flour without blanshing gives more smell of raw and not preferred when used as a fortifying material. The best time for blanching moringa leaves is 3 minutes because it can reduce smell of raw moringa and less decrease the value of micro-nutrients.

Abstract

This study aimed to examine the effect of Moringa leaf flour concentration on the physical and chemical properties and level of preference of Moringa corn bread. The study was conducted with variations of Moringa leaf flour concentration (TK): TK1 = 1%; TK2 = 3%; TK3 = 5%; TK4 = 7%. Parameters to be analyzed included physical properties, namely bread volume, specific volume of bread and bread elasticity. Chemical properties included water content, protein, vitamin C, β-karoten. The results showed that the highest macro- and micronutrient values in the addition of 7% Moringa leaf flour was inversely proportional to the physical properties of the bread, namely a decrease in the specific volume and elasticity of Moringa cornbread which resulted in a decrease in panelists' acceptance of Moringa cornbread products. TK3 was the best with protein value of 7.27 mg/100g, vitamin C 60.0 mg/100g, β-karoten 13909.99 µg/100g, specific volume of bread 3.71 cm3/g and bread elasticity. 75.14% and the highest sensory acceptance of moringa cornbread. Keyword: Physical, Chemical, Bread, Corn, Moringa
