Abstract

Bakery products such as bread, cake and cookies that currently exist in the market are generally made of wheat flour. Some individuals would suffer from allergy in consuming the consumption products that contain gluten which is found in wheat flour.The purpose of this activity is to produce bakery products such as bread, cake and cookies that are gluten free by using local tuber ingredients, i.e. cassava and sweet potatoes. The activity was started with processing cassavas, sweet potatotes, orange sweet potatoes to be powder which then was processed to be various types of bakery products. The variants of products that are marketed are as many as 31 types, consisting of 28 types of bakery products such as cakes and cookies, and 3 types of wet cake products. The types of bakery products that were sold was brownies, muffin, sponge cake, cookies and snacks with various variants such as steamed, baked, flavors addition of coffee, chocolate and mocha.  The bakery products are gluten-free so that they are safe to be consumed by people who are allergic to gluten. The wet cake products that were marketed were risoles, pastels and doughnuts. However, this type of cake is still wheat flour substitute product as much as 20%. This activity may support the national food security program.

Abstract

Laksa leaf is just used as vegetable, so that a processing is needed in order to increase its value added. Usual food processing using laksa leaf is sour vegetable. The laksa leaf is useful as antioxidan. The research was done to find ratio of tapioca flour with wheat flour and concentration of laksa leaf to produce chip. The research had been performed using completely randomized design (CRD) with 2 factors, i.e : the ratio of tapioca flour with wheat flour (T) : (100:0, 80:20, 60:40, 40:60) and concentration of laksa leaf (D) : (0%, 9%, 18%,  27%), Parameters analyzed were moisture content, ash content, fat content, fiber content, the expansion degree and organoleptic values (colour, aroma, taste, texture). The results showed that the ratio of tapioka flour with wheat flour had highly significant effect for all the parameters. The laksa leaf concentration had highly significant effect for all the parameters except expansion degree. The interaction between the two factors had highly significant effect on moisture content, fat content, organoleptic values and texture, had significant effect on ash content  and had no effect on   fiber content, expansion degree, colour and aroma. . Keywords : tapioka flour, wheat flour, laksa leaf, chips

Abstract

Noodles were usually made from wheat flour. Wheat is Indonesia imported commodity that due to limited stock, it can cause problems in food security. In order to solve the problems, food diversification is done by replacing noodle raw materials with potato starch. This study was done using Heat Moisture Treatment red potato starch to make instant noodle mixed with mocaf flour and wheat flour with different comparisons and 4 type of phosphate salts.The research was conducted in three phase i.e the manufacture of natural starch, modified by Heat Moisture Treatment (HMT) and then testing the physical and chemical characteristics of the modified potato starch HMT included moisture content, ash content, oil and water absorption, dextrose equivalent (DE), total sugar, reducing sugar, the degree of polymerization (DP), the clarity of paste, amilograph with rapid viscoanalizer, starch granules form and whiteness. Phase three was making noodles from composite flour and moisture content, ash content, protein content, fat content, fiber content, carbohydrate content, water absorption power, percent elongation, cooking loss, color scores before and after cooking, organoleptic test for aroma and flavor were tested. Composition of modified potato starch, mocaf flour and wheat flour of 15%:40%:45% with Sodium Tripoly Phospate respectively produced the best instant noodles.   Keywords: Potato, HMT modified starch, mocaf flour, wheat flour,  phosphate salt, instant noodles

Abstract

The research was conducted to determine the effect of lime chitosan concentration and storage time on the quality of fresh tofu. This study used a completely randomized design with two factors is: lime Chitosan concentration (K) : 0.25%, 0.5%, 0.75%, 1% and 1.25% and storage time (P) : 5, 10, and 15 days. The parameters analyzed were moisture content, ash content, total microbes, pH, protein content, and sensory characteristics (color, flavor and aroma, and texture). The results showed that the lime chitosan concentration had highly significant effect on all parameters and sensory characteristics. Storage time had highly significant effect on all parameters and sensory characteristics. Interaction of both factors had highly significant effect on total microbial, pH, protein content, and color, flavor and aroma. Lime chitosan concentration of 0.5% was the best treatment for the fresh tofu.

Abstract

This research was conducted to find the effect of the addition banana flour and soybean flour on the quality and characteristics of sponge cake. This research was performed in November 2011 - April 2012 at the Laboratory of Post-Harvest, Research Institute of Agricultural Technology, North Sumatra, using factorial completely randomized design with 2 factors, namely banana flour concentration (P): 15%, 30%, 45%, and 60% and soybean flour concentration (K): 0, 5%, 10%, and 15%. Parameters analyzed were moisture content, protein content, ash content, degree of swelling, organoleptic values of flavor, taste, and texture. The results showed that banana flour concentration gave highly significant effect on moisture content, degree of swelling, and organoleptic values of taste, and gave no significant effect on protein content, ash content, organoleptic values of flavor and texture. Soybean flour concentration gave highly significant effect on moisture content, ash content, degree of swelling, organoleptic values of taste and texture, and gave no significant effect on protein content, and organoleptic values of flavor. The combination of banana flour concentration and soybean flour concentration gave no significant effect on all parameters. The combination of banana flour concentration of 30% and soybean flour concentration of 5% gave the good and acceptable quality of sponge cake.

Abstract

This study was conducted to find the best amount of of jackfruit seed flour with tapioca and the best amount of sodium bicarbonate to produce crackers. Research was done using completely randomized design with two factors, namely the comparison of jackfruit seed flour wheat and tapioca flour (T): (1:3, 1:6, 1:9, and 1:12) and the amount of sodium bicarbonate (S): (0,5%, 1%, and 1,5%). Parameters analyzed were moisture content, ash content, fat content, protein content, the degree of development and the value of organoleptic (color, aroma, flavor and crispness). The results showed that the ratio of jackfruit seed flour and tapioca flour had highly significant effect on all parameters. The amount of sodium bicarbonate had a highly significant effect on water content, ash content, protein content, fat content, and degree of development of sensory crispness. The interaction between comparative jackfruit seed flour with tapioca flour had a highly significant effect on water content, ash content, protein content, fat content, organoleptic crispness, and the different degrees of development but had no significant effect on the organoleptic taste, color and aroma.
