Abstract

An experiment was conducted in order to study the influence of supplemented sucrose and injected insulin under different recovery times following transportation on lamb flavor quality. For the purpose the study used fifty four female local lamb (10 to 12 months of age) with weight ranging from 14 to 17 kg. The experimental lamb were assigned into a completely randomized design with 2x3x3 factorial arrangement with 3 replications. The first factor was sucrose supplementation with 2 levels (0 and 6 g/kg body weight). The second factor was insulin injection after transportation with 3 levels (0, 0,3 and 0,6 IU). The third factor was the duration of recovery times with 3 levels (2, 4 and 6 h prior to slaughtering). Parameters measured were glucose, fructose, and ribose. Results showed that feeding sugar and injecting insulin to lamb following transportation increased glucose, fructose, and ribose content of raw meat while recovery time was not affect meat sugar content. Interaction was not occur between treatment of Sugar, insulin, and recovery time.

Abstract

Andaliman (Zanthoxylum acanthopodium DC.) is a plant endemic to North Sumatra. Its fruit has a very specific citrus-like aroma, gives a tingling sensation and is commonly used for seasoning in Bataknese traditional cuisine. To extend the shelf life and preserve the quality of andaliman fruit, post-harvest handling is needed. Seven drying methods were applied and compared, i.e. sun, air, fluidized bed, oven, far infrared, freeze, and spray drying. Considering the physicochemical and sensory properties and efficiency, oven drying was selected for further study. The optimum condition for drying was temperature at 54 °C for 8 h resulting in 0.67 desirability level based on the response surface method (RSM). Spray drying encapsulation of andaliman fruit extract was performed at an inlet temperature of 150 °C with an extract to carrier ratio of 1:8. Maltodextrin (MD) and gum arabic (GA) with a ratio of 3:2 was chosen as the carrier agent. The quantitative descriptive analysis (QDA) result showed that the encapsulated andaliman powder had a flavor that resembled fresh andaliman with a more pronounced taste, a citrus-like trigeminal sensation, and a sour floral citrusy aroma.

Abstract

The utilization of carotenoid rich red fruit oil for food product development is still limited due to has low solubility in aqueous phase and unstable. Nanoencapsulation was proposed to improve the solubility as well as to retain the stability. This study aimed to determine the capability of nanoencapsulation process in maintaining the stability of carotenoid towards heat and light treatments and to estimate the shelf life of the encapsulant. Ionic gelation method was applied in the nanoencapsulation process using chitosan as a coating agent. Total carotenoid was calculated using Gross equation, while the estimation of shelf life of the product was predicted using Arrhenius model. Particle size of the best nanoencapsulation sample was 70.48 nm with a polydisperse index of 0.02 and zeta potential of 14.80 mV. These physical properties of nanoencapsulant agreed with the results of morphological measurement by TEM. The stability of carotenoid pigment in nanoencapsulant throughout several treatments, such as light (1700 lux, 12 hours), blanching (80 °C, 30 minutes), pasteurization (90 °C, 20 minutes), and sterilization (121 °C, 5 minutes) was higher compared to the stability of emulsion without treatment. The decreasing of total carotenoid in nanoencapsulant for each treatment was 6.92%; 13.51%; 17.77%; and 20.49%, while the reduction in emulsion was 26.33%; 45.25%; 54.46%; and 65.74%, respectively. Nanoencapsulation sample at room temperature (25 °C) has a shelf life of 5.2 months which was longer than the emulsion sample (0.5 months). Nanoencapsulation showed better protection on the stability of carotenoid pigment and increased the shelf life of red fruit oil. ABSTRAKPemanfaatan minyak buah merah yang kaya akan pigmen karotenoid pada produk pangan masih terbatas karena sifatnya kurang larut dalam fase air dan memiliki stabilitas yang rendah.

Abstract

The objective of this research is to develop a system dynamics model that represents the relationship between population sub system and land conversion sub system with freshwater availability sub system in Bekasi Regency. The models are used to predict the relationship until 2025. The models are designed, both with and without intervention factors to population behavior toward water. The purpose of this study is to strengthen water resources management planning in Bekasi Regency. The method of the research was system dynamics. Water availability as a system was represented as a simple model in line with the factors in this research, so that the model represents the real world. The Causal Loop Diagram showed that factors in sub system and inter sub system formed balancing causal feedback loop. Model behavior simulation showed that freshwater availability (i.e. surface water and shallow ground water) decreased substantially (collapse) from 2003 until 2025. The decrease was caused by water pollution rather than the population growth and land conversion increasing. Population numbers increased slowly (growth), while land carrying capacity decreased gradually (decay). It is predicted, if the condition does not change, water crisis will happen in 2018. When community's behavior for water (i.e. thrifty and sanitation behavior) increase begin 2008, it is predicted that beginning from 2009, the freshwater availability will increase, the water crisis can be suspended, and the freshwater inventory can be reserved. Based on those findings, it could be suggested that water resources management planning should consider water as a system and integrate supply side management, demand side management, and governance side management.
