Abstract

Meatballs are a food favored by the community, with the number of buyers classified as frequent at +30% even though the calories are high, reaching 68 calories per piece with a fat content of 60%. The purpose of this study was to produce vegetable meatballs with lower fat but high fiber content. The vegetable meatballs in this study were produced using Eucheuma cottonii seaweed gel without meat and wheat flour as its raw materials. The vegetable meatballs can be intended for consumers with certain conditions. The research method used was experimental using a randomized block design (RAK). The treatment in this study was the concentration of E.cottonii seaweed gel in the product formulation which was 0.5%, 1%, 1.5%, 2%, and 2.5%. Each treatment was repeated three times. The observed response was consumers' acceptance using hedonic and hedonic quality tests and the fat content of meatballs. The results showed that vegetable meatballs with 1.5% gel content were the most preferred by panelists which contain 3.5% crude fiber and 14% fat.

Abstract

High consumption of oranges (Citrus sinensis) leads to the increase of orange peel waste, that’s why those orange peel waste needs to be utilized as a value-added product, such as fruit candy. Fruit candy can be produced by a process called osmotic dehydration, which is the process of immersing food material in a hypertonic solution. This research was done with Randomized Block Design to understand the effect of immersion time (2, 4, and 6 hours) and blanching time as the pretreatment (2,5, 5, and 7,5 minutes). This research was done in triplicate. The parameters that were observed are solid gain (SG), water loss (WL), weight reduction (WR), water content, and colors (L*, a*, and b*). The results indicated that the increase in immersion and blanching time causes the value of solid gain (SG) and water loss (WL) to increase, weight reduction to decrease then increase, and water content to decrease. Analysis of Variance test suggests that immersion time has a significant effect on SG, WL, WR, water content, L*, and a*. On the other hand, blanching time only significantly affects SG, WL, WR, and water content. According to Multiple Attribute Utility Theory, the best treatment in this research, regarding the results of SG, WL, WR, and water content, is the treatment with 6 hours immersion time and 7,5 minutes blanching time.

Abstract

The ohmic technology was applied for the carrageenan extraction process from seaweed (Eucheuma cattoni). The principle of ohmic technology is based on passing an electric current through seaweed and triggering its internal energy. The objectives of this study were to compare two different extraction methods using the ohmic and conventional heaters in terms of the quality of carrageen flour. This study were conducted by two different heating sources during the seaweed extraction process, i.e., ohmic heating and conventional heating from a gas stove. Each method was repeated three times. The extracted filtrates were dried, milled, and sieved using an 80-mesh sieve, then the quality of carrageenan flour was measured. Quality of extracted carrageenan flour using the ohmic and conventional heating methods are: 1) the extraction yield of 45%; 42%, 2) moisture content 10%; 18%, 3) white degree 77.63%; 74.27%, 4) viscosity 6.02 cp; 4.57 cp and 5) gel strength 174 gr / cm2: 159 gr / cm2. The result of statistical analysis between two methods with α 5% showed no significant difference in yield parameters however significantly different for water content, white degree, viscosity, and gel strength. The quality of extracted carrageenan flour of the ohmic heating method was better compared to the conventional heater.

Abstract

Red dragon fruit contains anthocyanins which act as natural dyes with a purplish red color. The purpose of this study was to determine the characteristics of red dragon fruit as a raw material for natural coloring pigments and to determine the effect of blanching on the characteristics of the red dragon fruit pigment ethanol extract. The study was conducted using a laboratory experimental method using a completely randomized design (RAL) with a single factor, namely blanching time. The blanching time is denoted by 1 (0 minutes), 2 (3 minutes), 3 (5 minutes) and 4 (7 minutes). Data from research results related to red dragon fruit are presented in tables and analyzed descriptively, while data from ethanol extract of red dragon fruit pigments were analyzed by linear regression analysis. The results showed that the pH of the raw material characteristics was highest in the fresh treatment and the lowest in the blanching treatment. The results of the highest lightness, redness and yellowness were obtained in the blanching, blanching and fresh treatments, respectively. While the lowest values ​​were in the fresh, fresh and blanching treatments. The highest total dissolved solids yield was in the fresh treatment and the lowest was in the blanching treatment. Blanching treatment has an effect on yield, reddish color, total dissolved solids and has no effect on pH, color intensity and color lightness.

Abstract

A study has been conducted to utilize lemuru fish into fish meal products. This study aims to determine the appropriate processing method for the manufacture of lemuru fish meal products and to determine the physicochemical characteristics of lemuru fish meal. Lemuru fish are processed into fish meal with three different processing treatments, namely boiling, pressure steaming, and using temperature of 50˚C and 60˚C in each processing. The fish meal obtained was analyzed with parameters of water content, ash content, fat content, protein content and degree of whiteness according to the Indonesian National Standard SNI 01-2715-1996. The result of this study indicate that the best results from lemuru fish meal in the analysis of water content are boiling treatment with mabu 60˚C (5,24%), ash content of 50˚C temperature treatment (3,99%), protein content of 60˚C boiling treatment (49,41%), the fat content of the sub-boiling treatment was 60˚C (7%), and the degree of whiteness of the presto treatment been carried out is the boiling treatment using a temperature of 60˚C.
