Gelatin is an intermediate ingredient which is oftenly used in many field such as food, pharmacy, and cosmetics. It is usually extracted from pig and cow. Halal issue of gelatin sources and the outbreaks of mad cow diseases encouraged people to find an alternative sources of gelatin. One of the alternative sources of gelatin was duck bone. The aim of this research was to describe physicochemical properties of duck bone gelatin which is extracted by using acid extraction method as an alternative sources of halal gelatin. The extraction of duck bone gelatin used 5% concentration of HCl (hydrochloric acid). The extraction process consisted of four steps, they were degreassing, defating, demineralization, and acid extraction. The result showed that gelatin which was extracted from duck bone had these several characteristic: yield of 6.24%, pH 4.0, water content of 13.43%, ash content of 13.42%, protein content of 65.43%, and whiteness degree of 30.35%. Generally, gelatin which was extracted from duck bone had similar characteristic with commercial gelatin and SNI standard. Further researcher had been suggested to reoptimized extraction method in order to reduce ash content.

Pectin is extensively utilized by the food processors especially for conversion of low grade fruits in to good quality products like jam, jelly, marmalade, and candies. Pectin has many applications in food and pharmaceuticals products as gelling agents and stabilizers.  This research aims to utilize banana peel  waste (Musa sapientum) as a source of pectin. The research used a  solvent extraction method using hydrochloric acid (HCl) in additional to  ethanol  to precipitate the pectin and the last step  drying process to obtain dry pectin. The fixed variables which were used in this research were 10 grams of banana peel (Musa sapientum),  10% water content of sample, and hydrochloric acid (HCl) as a solvent. The  extraction process was carried out by pH 1; 1.5, 2; the  time of 70, 80, 90, 100 minutes, and the temperature of 80 oC, 90 oC. The results showed that the highest  yield of the extraction was obtained at  90 oC, pH 1.5  during 80 minutes with  11.93%  water content of 0.79% ash content,  about 600-800mg and 4, 43% methoxyl  content.

Anguilla marmorata (Q.) Gaimard, eel bonefish is one of the potentials sources for gelatin manufacture. This study aims to determine the concentration of hydrochloric acid (3%; 4%) and to optimize demineralization time (12 hours; 24 hours) for thequality of gelatin. Characteristic of gelatin was determined by analysis of water content, ash content and protein content. To optimize gelatin extraction from eel fish bone, Mann Whitney test with 4 – factor was adopted. Spectrophotometer FTIR was used to analyze functional groups of gelatin. Values of water content, ash and protein content of each combination of acid chloride and demineralization time have met the requirements. The spectrum of FTIR showed a typical gelatin functional group. The best combination of treatment is at 3% hydrochloric acid concentration and 12 hours of demineralization time.

Protein Levels

Basically, gelatin is pure protein food ingredient, obtained from thermal collagen denaturation from animals. Gelatin is used as a stabilizer, gelling agent, binder, thickener, emulsifier, adhesive, whipping agent, and food wrap which is edible coating. Protein levels in fish skin determine the amount of collagen contained in skin tissue, so the baronang fish skin has a considerable opportunity as a source of collagen to be hydrolyzed into gelatin. This study aimed to determine the characteristics of gelatin produced from baronang fish skin by enzymatic extraction and to determine the best treatment of a combination of enzyme concentrations with extraction time. Making gelatine was carried out by hydrolysis using bromelin enzyme at a concentration of 1%, 1.5% and 2% with extraction time of 2 hours, 4 hours and 6 hours. The result, obtained gelatine with water content ranging from 3.13-5.83%, the water content ranged from 0.17-3.56%, ash content 0.35 - 3.65% and protein levels ranged from 91-94, 72%. The chemical characteristics of gelatine from baronang fish skin have a yield of up to 6%, water content <6%, ash content <4% and protein content reaching 94%. The best treatment was obtained at 1% enzyme concentration and extraction for 4 hours with a protein content of 94.72%.

Adlay is a nutritious grain that has the potential as an alternative food because it has a high protein and fat content of 14.10% and 7.90%, respectively. The use of Adlay as flour still has a weakness, namely the functional properties of Adlay flour such as low swelling power. One way to improve the characteristics of Adlay flour is by fermentation using Rhizopus oligosporus. The fermentation duration is the time that allows changes in the characteristics of the flour due to the fermentation. This study aims to determine the effect of differences in fermentation duration using Rhizopus oligosporus on the physical, chemical, and functional characteristics of Adlay flour produced from fermented Adlay seeds. This study used one factor, namely the lengths of fermentation for 0, 12, 24, 30, 36 and 48 hours. The analysis in this study included whiteness, yield, pH, water content, ash content, protein content, fat content, carbohydrate content, swelling power and solubility, oil holding capacity (OHC) and water holding capacity (WHC). The results have shown that the longer the fermentation duration the lower rate of whiteness, pH, yield, water content, fat content, and carbohydrate content will become, while some functional properties of Adlay flour become better with increasing values of ash content, protein content, swelling power, solubility, Oil Holding Capacity (OHC), and Water Holding Capacity (WHC).

The purpose of this research to find the effect of the comparison of pregelatinization red rice flour with wheat flour on the characteristics of crackers and also to find the best ratio of red rice flour with wheat flour to the characteristics of crackers. This study used a Compeletely Randomized Design (CRD) with a comparison of red rice flour pregelatinization with wheat flour consisting of 6 treatment namely 0% : 100%;10% : 90%; 20% : 80%; 30% : 70%;40% : 60%; 50% : 50%. The treatment repeated 3 times, so that resulting in 18 experimental units. The resulting data is analyzed with variance and if the inter treatment effect on the observed variance, then continue with Duncan test. The result showed that pregelatinization red rice flour and wheat flour significantly affected to water content, protein content, total phenol, and antioxidant activity in crackers and had no significant effect on ash content. The comparison ratio of 50% pregelatinazation red rice flour with 50% wheat flour produces crackers with the best characteristics, namely: water content of 1.15%, ash content of 1.73%, 10.30% protein content, total phenol 158.83% and 45.17% antioxidant activity colour very like, texture crispy, overall liked, aroma,taste and overall acceptance like.
