<p>Sweet potato is one type of tubers found in Indonesia. <em>Hybrid</em> of sweet potato flour is obtained from the modification of the processing by fermentation using lactic acid bacteria. The purpose of this study was to determine the nutritional and antioxidant content of various types of <em>hybrid</em> sweet potato flour. This research is an experimental laboratory with a true-experiment design. The experiment was arranged in a complete randomized block design (RCB) with three replications. The treatments are 6 types of sweet potatoes which include purple sweet potato Var.Antin 1, purple sweet potato val.local, white sweet potato, orange sweet potato, Japanese purple sweet potato Var.Ayamurasaki and cilembu sweet potato. The study included the fermentation process using lactic acid bacteria (Acetobacter xylinum) addition concentration of 5%, siege, analysis of nutrient content (water, ash, protein, fat, fiber and carbohydrates) and antioxidant activity of various types of <em>hybrid</em> sweet potato flour. The results showed that various types of <em>hybrid</em> sweet potato flour significantly affect the nutritional content which includes water content, ash content, fat content, protein content, fiber content and total carbohydrate. The result of antioxidant activity in various types of <em>hybrid</em> sweet potato flour after fermentation treatment in a concentration of 5% Acetobacter xylinum ranged from 29,383-53.7929%. The lowest value obtained at cilembu <em>hybrid</em> sweet potato flour and the highest value was obtained from the Japanese <em>hybrid</em> sweet potato flour var.Ayamurasaki.</p>

Sweet potato has great potency to be developed as an alternative carbohydrate source in the form of modified sweet potato flour. Autoclaving retrogradation is a physical modification method to improve the physicochemical characteristics of flour. The purpose of this study was to determine the effect of the autoclaving retrogradation method on the characteristics of various sweet potato flour: dietary fiber, resistant starch, starch digestibility, nutritional content, and antioxidant, and to determine the best modified sweet potato flour. The experimental design used a non-factorial completely randomized block design with four replications. The treatment consisted of 6 types of sweet potato, namely control (purple sweet potato without treatment), orange sweet potato, purple sweet potato, honey-sweet potato, red sweet potato, and purple white sweet potato). The results showed that there were significant differences in dietary fiber, levels of resistant starch, digestibility of starch, nutritional content, and antioxidant activity amongst various types of modified sweet potato flour. The best modified sweet potato flour was found in modified red sweet potato flour which contained 44.64% dietary fiber, 19.75% resistant starch, 13.50% starch digestibility, 66.32%  antioxidant activity, with comparable nutritional content.

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.

Abstrak. Pemanfaatan pangan lokal sagu dapat mengurangi konsumsi terigu dalam  pembuatan mi. Tujuan penelitian ini untuk mempelajari pembuatan mi basah dari pati sagu terfermentasi dan substitusi tepung (MOCAF, tepung ubi jalar fermentasi, dan tepung kacang hijau).  Penelitian pembuatan mi basah menggunakan  Rancangan Acak Kelompok  (RAK) faktorial dengan 2 faktor. Faktor pertama, lama fermentasi pati sagu yang terdiri atas tiga taraf yaitu FI= 7 hari, F2=14 hari, dan F3= 21 hari. Faktor ke dua adalah substitusi pati dengan tepung (80%:20%), dengan  tiga  taraf yaitu S1=pati sagu fermentasi:MOCAF, S2=pati sagu fermentasi:tepung ubi jalar kuning fermentasi, dan S3=pati sagu fermentasi:tepung kacang hijau. Analisis yang dilakukan adalah  uji organoleptik secara deskriftif  yaitu kelengketan, elastisitas,warna, aroma, dan overall mi basah. Pembuatan mi basah menunjukkan bahwa perlakuan lama fermentasi pati sagu F1(7 hari) menghasilkan  nilai elastisitas mi basah yang lebih tinggi (lebih baik) (P≤0,05), dibandingkan mi basah dari pati sagu F2 (14 hari) dan F3 (21 hari), walaupun kelengketan, dan aroma asam mi basahnya rendah (kurang baik) (P≤0,05).  Produk mi basah terbaik  yaitu mi  yang  terbuat dari pati sagu yang difermentasi 7 hari (F1) dengan substitusi tepung ubi jalar fermentasi, kelengketan 2,05 (lengket), elastisitas 2,43 (tidak elastis), warna 2,30  (tidak cerah) aroma asam 2,80 (tidak asam), rasa asam 2,88 (tidak asam), overall  2,60 (baik).Effectts of  Natural Sago Starch Fermentation  Quality Sensory of  Wet Noodles Made by Substituted no wheat  Flour (Mocaf, Fermented Sweet Potato Flour, Mung Bean)Abstract. Utilization of local food sago can reduce the consumption of wheat in the manufacture of noodles. The purpose of this research was to study making wet noodles of fermented sago starch and the use of flour substitution (mocaf, fermented sweet potato flour, and mung bean flour) in the manufacture of wet noodles. A randomized block design with 2 factors was use in the manufacture of wet noodles. First factor is sago starch fermentation period consist of three levels ie FI = 7 days, F2 = 14 days, and F3 = 21 days. Second factor is the substitution of sago starch with flour (80%: 20%), there are three levels ie S1 = fermented sago starch : mocaf, S2 = fermented sago starch : fermented yellow sweet potato flour, and S3 = fermented sago starch: mung bean flour. Analysis of the sago starch and substituted flour include descriptive organoleptic tests  stickiness, elasticity, color, flavor, and overall of wet noodles. Manufacture of wet noodles showed that sago starch fermentation time F1 resulted in higher (better) (P≤0,05) breaking test and elasticity wet noodles compared to wet noodles from sago starch F2 and F3, although the adhesiveness and the sour aroma of the wet noodles were low (worse) (P≤0,05). descriptive organoleptic values of stickiness 2.05 (sticky), elasticity 2.43 (inelastic), color 2,30 (not bright), sourness aroma 2.80 ( not sour), sourness taste 2.88 (not sour), overalls 2.60 (good).

Purple Sweet Potato

Purple sweet potato is one type of tuber that is rich in carbohydrates in the form of starch and fiber. It also contains purple anthocyanin pigments. In this research, purple sweet potato was processed into flour and starch. Starch processing solid waste can be utilized by processing it into fiber flour. Purple sweet potato flour and fiber were then used as the basis for making biscuits at a ratio of 75: 25 and compared to biscuits made from 100% purple sweet potato flour and wheat flour. The resulting biscuits were then analyzed for their chemical characteristics. The results showed that the ratio of flour gave a very significantly different effect on the value of water content, total dietary fiber content, insoluble dietary fiber content and % nutritional adequacy rate of food fiber, and had no significant effect on the value of ash content, protein content, fat content, content carbohydrates, total flavonoids, insoluble dietary fiber content, calorie intake and fulfillment of daily energy adequacy.
