Abstract

Sweet potato is a food plant group that is most widely cultivated as an agricultural commodity with carbohydrate sources. The carbohydrate and starch content of orange sweet potato allows the material to be processed into flour and substitutes tapioca flour in the manufacture of garlic cracker products. The purpose of this study was to analyze the physical properties of orange sweet potato flour as a substitute for making onion crackers, determine the best formulation by adding orange sweet potato flour to the onion cracker product, and analyzing the effect of adding orange sweet potato flour to the preference level of panelists for onion cracker products. The research design used in the study consisted of 4 types of formulations with the addition of 0%, 10%, 20% and 30% tapioca flour. Tests carried out on onion crackers substituted for orange sweet potato flour were water content test, ash content test, and organoleptic test. The results showed that the orange sweet potato flour had the characteristics of an orange color, a distinctive aroma of orange sweet potato, and a smooth texture. The best formulation is the addition of orange sweet potato flour as much as 10% (F1) with a moisture content value of 5%, an ash content of 2.3%, and Preferred by panelist (total score 15.56). The addition of orange sweet potato flour to garlic cracker products affected the panelists' preference for color and aroma, but did not affect the taste and texture of onion crackers.

Abstract

 Composite flour is flour made from two foodstuffs, namely Tengger potatoes and moringa leaves. Composite flour can be used as a substitute substitute for wheat flour substitutes for the manufacture of crackers products. Crackers are a type of biscuits that go through the fermentation process. Fermentation aims to maturate the dough, forming a good taste and texture. This study aims to find out ptorein levels, moisture content, free fatty acid content, flowering power, broken power and browning index crackers substitution of composite flour with fermentation duration of 0 hours, 1 hour, and 2 hours. This study is an experimental study using a Complete RandomIzed Design with 3 treatments and two replays. The data was statistically tested using ANOVA and Duncan's Multiple Range Test (DMRT). The results of the analysis showed the long fermentation treatment of dough crackers differed markedly from its chemical properties and physical properties. Crackers with a fermentation time of 2 hours contain the highest protein content of 16.44%, the greatest moisture content of 0.916%, and the lowest free fatty acid content of 0.014%, and physical properties including the highest growth power of 28.237%, the lowest broken power of 0.006N/Cm² and the brownish index of 88.469%.

Abstract

This study aims to determine the effect of the method and time of extraction on the yield and characteristics of pektin red dragon fruit leather according to the SNI pektin (01-2238-1991) and the International Pektin Producers Association (IPPA) 2003. The experimentals design was a Completely Randomized Design with 2 factors. The first factor was the extraction method used, namely (M1 = conventional method, M2 = ultrasonik method). The second factor was extraction time (W1 = 15 minutes, W2 = 30 minutes, W3 = 60 minutes, and W4 = 90 minutes. The results showed that the extraction method had a significant effect on yield, equivalent weight, galacturonic acid content, degree of esterification, water content and ash content, but had no significant effect on methoxyl content. Extraction time significantly affected yield, equivalent weight, methoxyl content, galacturonic acid content, degree of esterification, water content and ash content. While the interaction of the two treatments had a significant effect on yield, equivalent weight, and water content. The highest yield was obtained using the ultrasonik method for 60 minutes with a value of 13.57%. The equivalent weight that meets IPPA (2003) and SNI pektin standards (01-2238-1991) is found in conventional and ultrasonik methods at 30 and 60 minutes.

Abstract

Anthocyanins present in the red dragon fruit peel (Hylocereus polyrhizus) can be used as natural dyes. An extraction procedure can be used to acquire anthocyanins. The maceration method was used to isolate anthocyanin dyes in this analysis. The aim of this study was to see how the solvent ratio affected the total anthocyanin content in the skin of red dragon fruit. This research used laboratory experimental method using descriptive analysis. The solvent ratios used were (1:30, 1:40, 1:50 and 1:60) with a mixture of distilled water with 10% citric acid as the solvent. Parameters observed were total yield, pH, residual solvent content, spesific gravity and total anthocyanin content.  The best treatment was found to be red dragon fruit peel with a solvent ratio of 1:30, which produced the highest total anthocyanin content of 4.73 mg/L. This treatment resulted total yield 7.40%, residual solvent content 0.05%, spesific gravity 1.30, and pH 1.05, respectively.  It was proven that the more solvent added could linearly decrease the effectiveness of anthocyanin extraction of dragon fruit peel extracts.
