Abstract

Oxygen indicators in food packaging can be used to monitor the shelf life and quality of the product, especially in a vacuum or modified atmosphere packaged, by sensing the indicator's color change. The mechanism of the oxygen indicator is a redox reaction which is compromised redox dye, reducing compound, and alkali compound. These substances can be formulated as a tablet/sachet or a printed layer or laminated in a polymer film. This study aimed to examine the performance of the oxygen indicator in various concentrations of glucose and NaOH. This research was carried out in 3 stages, i.e. (i) producing oxygen indicators; (ii) characterizing the oxygen indicator before it was activated, and (iii) testing the irreversibility of the indicator. The results showed that the oxygen indicator had been successfully made in two compartments of NaOH and glucose-methylene blue with LDPE as a membrane barrier. The indicator's color remains the same in blue before it was activated. It seems that the concentration of glucose and natrium oxide did not have any significant difference in the initial color of the indicator. Once the indicator was activated by pressing the NaOH compartment, the color of the indicator turned purplish, and after a long while, the indicator turned white. The concentration of NaOH and storage temperature significantly affected the turning color's acceleration. A sample in the concentration of glucose 0.2 M and NaOH 0.2 M proved irreversible with ohue values of 208.57 to 313.201.© hak cipta dilindungi undang-undang.

Abstract

The demand for stevia extract consumption as an alternative sweetener that contains stevioside with zero-calorie is increasing. However, dark color and high tannin content from stevia leaf extract causes a disturbing aftertaste and reduces interest in consumption. Therefore, the purification process is a mandatory step to be done. Several studies on purification methods show the best approach by adsorption using bentonite. However, natural bentonite has limited adsorption capacity and low selectivity. An activation with acid and high temperature is expected to increase the adsorption capacity of color and its selectivity on maintaining the stevioside at the extract. This study aimed to obtain the optimum acid concentration and temperature for the activation using the Response Surface Method (RSM) experimental design and its application to the purification of stevia leaf extract. Based on the parameter of methylene blue number, the most optimum concentration of H2SO4 used for activation was 0.17 N for both natural bentonite. The heating temperature was 358°C for Na-bentonite and 481°C for Ca bentonite. The maximum adsorption capacities of activated Na and Ca-bentonite were increased from 15.65 and 38.23 mg g-1 to 197.72 and 169.52 mg g-1, respectively. The best adsorbent used for purification is Ca-activated, which increased extract clarification up to 81.37% at 655 nm and 86.64% at 410 nm compared to natural Ca bentonite. It also reduced tannin up to 97.46% and was more selective to recover 50.64% stevia content in the solution, which was higher than other previously reported studies.

Abstract

Sago starch production in local industries is still carried out traditionally and uses poor-quality water. This production causes sago starch to be fermented spontaneously, resulting in sour sago and possibly contamination by pathogenic bacteria. Lactic acid bacteria (LAB) can produce lactic acid and are suitable for use as a starter. Adding LAB as a starter in sago starch fermentation is expected to reduce the number of pathogenic bacterial growths, thereby increasing food safety in sago starch. This research aimed to obtain LAB and evaluate their use in sago starch fermentation to improve food safety. LAB selection was conducted by testing the LAB tolerance ability to low pH and the adaptability of the LAB growth in sago starch. This study was carried out using and without a LAB liquid starter. The water source during the fermentation originated from drinking water and the sago starch industrial factory. The fermentation was carried out for ten days at room temperature with an observation every two days. The results showed that fermented sago starch using drinking water did not harbor E. coli, Salmonella, or Shigella bacterial contamination. In contrast, sago starch fermented using water from the factory harbored these bacterial contaminations. Adding LAB IL1 isolate as a starter in fermentation showed the ability to reduce the number of pathogenic bacteria in sago starch.

Abstract

North Sumatra is the largest producer of incense (benzoin) in Indonesia and the world. There are 3 varieties of incense that have the potential to be developed. Indonesia has exported incense to Singapore, Malaysia, and China. Incense is exported in the form of raw materials, so the added value is minimal. In order to increase the added value of incense, it can be produced into incense extract. So far, extraction methods have been carried out using conventional methods, including maceration, boiling with water, and distillation with water vapor. The potential of incense has not been fully utilized, especially from its extraction method, so it still needs to be developed. This article aims to review and identify the chemical components of frankincense (Styrax benzoin) and its extraction methods. In addition, the prospects for product development from frankincense are also discussed. Incense extraction with Ultrasonification Assistant Extraction (UAE) is expected to increase the efficiency of the extraction process. The use of solvents and low temperatures, as well as a short extraction time, can maintain the quality of the incense extract. Incense extract can be applied as raw material for perfumes, pharmaceuticals, medicines, and nano applications such as anticancer and antibiofilm. The incense consists of some active ingredients such as cinnamic acid, benzoic acid esters (such as coniferyl cinnamate and cinnamyl), pinoresinol, -caumary benzoate, benzoic acid esters, and triterpenes. These active ingredients are applied as antibacterial and antioxidants. This literature review provides an overview of the characteristics of active ingredients in incense to expand its applications. Incense extract can be applied as a food additive, pharmaceutical, and health ingredient.

Abstract

Robusta coffee is widely cultivated in Indonesia, but it struggles to dominate the global market due to its bitterness, slightly sour taste, and higher caffeine content. Coffee bean fermentation can be done to reduce undesirable characteristics in robusta coffee. This study aimed to evaluate the effects of lactic acid bacteria fermentation on the quality of coffee and its brewing characteristics, comparing it to spontaneous fermentation. The goal was to explore the potential of fermented coffee beans as functional beverages with health benefits. Three lactic acid bacteria (LAB) isolates were tested, and Lactiplantibacillus plantarum H 2.34 was identified as the most effective starter culture for coffee fermentation. After 12 hours of fermentation using coffee mucilage, LAB growth was significantly enhanced. A significant increase in flavonoid content was observed in coffee fermented with the starter culture. All brewed coffee samples demonstrated strong antioxidant activity, and LAB fermentation successfully reduced caffeine content by 4.85%. These results suggest that fermented robusta coffee could offer functional health benefits while improving its sensory profile.

Abstract

Managing end-of-life tyres (ELTs) has become an urgent global issue because tyres are difficult to decompose naturally and take more than 50 years to break down. In the Jabodetabek (Jakarta, Bogor, Depok, Tangerang, Bekasi) area, ELT generation is estimated at 2.5–3 million units annually, with the most significant contributions from Karawang (1,000 units per month) and Bogor (820 units per month). Bias-ply used tires, which contain up to 70% rubber, have significant potential for recycling into raw materials for new tires through reclaimed rubber technology, aligning with the principles of a circular economy. This study aims to map the supply chain ecosystem of ELTs, identify key stakeholders, and optimise material flow to support the development of the rubber industry from reclaimed materials. The study employs a qualitative descriptive method. The number of research locations was determined using the Solvin method with an error rate of 25%. Observations were performed at 15 specific tire shops, two truck tire shops, three fleets, and three used tire collectors in the Jabodetabek and West Java areas. The findings indicate that the total estimated number of ELTs collected in Jabodetabek from tire stores, truck tires, fleets, and collectors reaches 2,860 monthly units. The main challenges in ELT management include limited storage facilities, low awareness of the economic value of waste, and a predominantly conventional management system. The study also reveals that only 20% of ELTs are utilised optimally, highlighting a significant untapped potential.  Keywords: used tires, reclaimed rubber, supply chain, circular economy

Abstract

Carrageenan, a natural sulfated polysaccharide extracted from red seaweed, has gained significant attention in the development of drug delivery systems, particularly as a capsule-forming material. With its biodegradable, biocompatible, and gel-forming properties, carrageenan offers great potential as a plant-based alternative to animal-derived gelatin. This review evaluates the potential of carrageenan, especially iota-carrageenan, in the production of soft capsules as a gelatin substitute, and compares the characteristics of carrageenan-based hard and soft capsules. Soft capsules are generally formulated with iota-carrageenan and plasticizers such as glycerol to achieve optimal flexibility, while hard capsules utilize kappa-carrageenan due to its stronger gel texture. Structural modifications, including depolymerization and polymer blending, have been reported to improve viscosity, elasticity, and disintegration time of carrageenan capsules. Nevertheless, limitations remain, such as high viscosity and slower disintegration compared to gelatin-based capsules. Therefore, formulation optimization and advanced extraction techniques are essential to enhance carrageenan capsule performance. Future research should emphasize cost-effective and high-purity extraction methods, engineered depolymerization processes, and the modification of kappa-carrageenan to exhibit iota-like flexibility. These strategies are expected to advance the feasibility of tropical seaweed-derived carrageenan as a sustainable and halal-compliant material for pharmaceutical capsule applications.
