Abstract

Salted egg is easily preserved of egg products. The making process was added liquid smoke. Therefore, the objective was to determine chemical characteristics (yolk index, oil exudation and salt content) of duck egg salted. Completely Randomized Design (CRD) was used throughout the research. They were run triplicate with differences concentration of liquid smoke (control, 1%, and 1.25%). They were differences salting time process (0, 1, 2, 3, and 4 weeks). Yolk index of control sample were no different statically compared to that of salted egg with liquid smoke treatment (p > 0.05). Significant different of yolk index (p < 0.05) increased along with increase of salting time (4 weeks). Significant differences (p < 0.05) were found on oil exudation of control sample compared to that salted egg with presence of liquid smoke. Oil exudation of salted egg yolk increased with increasing salting time (p < 0.05) up to 4 weeks. Significant differences (p < 0.05) were obtained on the salt content of control compared to that salted egg white treatment of liquid smoke. Salt content white increased along with the increase of salting time (p < 0.05).

Abstract

The objective of this studies were to determine the physical properties of viscosity and organoleptic of yogurt drink with the suplementation of mangosteen peel extract. The experimental design used was Completely Randomized Design (CRD) of the factorial pattern. The first factor was the difference of mangosteen peel extract level (0%, 3% and 6% v / v), while the second factor was the storage time of yogurt (0, 1, and 2 weeks) with 3 replications. The results showed that the supplementation of mangosteen peel extract on yogurt drink gave significant effect (p <0.05) on viscosity, color and sensory analysis (viscosity and texture). Yogurt drink was recommendation with mangosteen peel extract 3% (74.65cp), lightness (L) 79.89, redness (a*) 0.14 yellowness (b*) 2.32, sensory analysis of viscosity with score 2.84 (moderate viscosity), organoleptics of color 3.52 (white yelowness) and texture test with score 2.12 (moderate smooth). It can be concluded that the addition of mangosteen peel extract can improve the quality of physical, color, organoleptik yogurt drink. The use of mangosteen peel extract will increase the economic value and product diversification.

Abstract

Collagen is one of the protein derivative products that can be produced by hydrolysis process. Collagen proteins found one of them in bone cattle. The protein is strongly bound to minerals in bone. The process of collagen extraction of bone requires a special method. One of them is demineralization process. The combination of several process methods allows collagen to have different properties. This study aims to evaluate the properties of collagen extract produced from broiler bone in the application of a combination of different processes. The study was used a major sample of composite bone from broiler. The main ingredient is using acetic acid (CH3COOH 1M). The applied treatment was a combination of the use of CH3COOH concentration levels (8%, 10% and 12%) with the length of process (24 and 48 hours)[B1] . The data were analyzed by ANOVA using the basic design of Completely Randomized Design (CRD) factorial pattern. Parameters observed included yield, gel strength, viscosity and pH. The results showed that the difference of concentration had significant effect (P<0,05) to pH and viscosity, but no significant effect (P> 0,05) to yield and gel strength. The process length had significant effect (P<0,05) to pH, but to yield, gel strength and viscosity had no significant effect (P>0,05). Application of 10% CH3COOH concentration with a 24 h process length showed better properties in collagen-based composite bone of broiler.  [B1]Variables measured?

Abstract

The objective of this research was to analyze sensory evaluation quality and total lactic acid bacteria of corn yogurt added with skim milk and carrageenan. This research used experimental laboratory method with completely randomized design and four replications. The treatment used were skim milk with concentration (2.5; 3; 3.5% b/v) dan carrageenan (0.5; 0.75; 1 % b/v). The result showed that the treatment gave significant different effect (p <0,05) on sensory evaluation quality from texture aspect; the addition of various concentrations of skim milk, and carrageenan concentrations, and the interaction did not give a different effect (p>0.05) on the total lactic acid bacteria, organoleptic (aroma and color). The addition of various of skim milk, and carrageenan concentrations gave total of total lactic acid bacteria, organoleptic (color, aroma and texture) was 2.83 x 108-4.4 x 108 CFU/ml; white to yellowness; acidness to acid; and thickness to thick. The best treatment of this research is the addition of skim 5% and carrageenan 0.75% with total lactic acid bacteria 4.4 x 108, the aroma is acidness, the color is yellowness, the texture is thickness. It could be concluded that the addition of skim milk and carrageenan in corn yogurt production can be accepted by consumers and increase the activity of lactic acid bacteria

Abstract

The objective of this study was to optimization antioxidant activity of active peptides of chicken feet with papain hydrolysis. The research method was experimental design conducted using Factorial Completely Randomized Design. Treatments included papain concentration (control (0%) , 1%, 2%  and 4%) and Incubation time (24 hours, 36 hours and 48 hours) were repeated four times. The variables observed were proximate analysis,microstructure, dissolved protein concentration and antioxidant activity. The results indicate that the treatment of papain concentration and incubation time variations in chicken feet protein extraction gave a differenceinfluence (P <0.05) to the concentration of solubility protein and antioxidant activity. The interaction of 3% papain concentration and 36 hours incubation time resulted in the highest  antioxidant activity amount 55.10 ± 2.24 %. It could be concluded that chicken feet produced bioctive peptide compound that gave high antioxidant activity optimized by hydrolysis of papain enzymes thereby increasing their functional value.

Abstract

Yogurt as a fermented dairy product has been providing several benefits for human health and appropriate for people with lactose intolerance. Recently, the consumption level of yogurt has significantly increased. Starch can be used as an alternative hydrocolloid in the manufacturing process of yogurt. Indonesian Canna edulis Ker contains 63.27% amylopectin that has the potential used as an alternative hydrocolloid. Amylopectin has a very high capability of the water holding capacity to increase the viscosity and maintain the stability of yogurt drink. The present research was to determine the additional effects of Canna starch as an alternative hydrocolloid on the physicochemical and sensory properties of the yogurt drink during storage. Concentrations of 0.1%, 0.2%, 0.3%, and 0.4% canna starch and 0.2% CMC (control) were added to make yogurt. All treatments were carried out with four replications. Samples were refrigerated at 4oC for 24 hours and then analyzed for pH, titratable acidity, viscosity, syneresis, sedimentable fraction, and sensory properties. Data were analyzed by one way ANOVA, and followed by Duncan's multiple range test (DMRT). Data from the pH, titratable acidity, syneresis, sedimentable fraction, viscosity and sensory analyses obtained from the present study indicated that concentration of 0.1–0.4% (w/v) Canna starch could be applicable in the manufacture of the yogurt drink. Furthermore, it was found that 0.1% (w/v) of Canna starch selected as the best concentration could be used in yogurt manufacture process that resulted in similar sensory quality compared with CMC as commercial hydrocolloid.
