Abstract

Milk is a highly perishable food due to its nutritional composition for microbial growth. Improper milk handling practices cause nutritional reduction and microbial contamination in milk. Collagen drinks are currently a growing commercial product. Therefore, this study aimed to determine the effect of hydrolyzed bovine collagen concentration and pulsed electric field (PEF) time on the physical, microbiological, and organoleptic qualities of milk enriched with hydrolyzed bovine collagen, as well as to determine the best treatment. Central composite design (CCD) for Response Surface Methodology (RSM) was used in this experimental design to explore optimal response based on the relationship between collagen concentration and PEF processing time. This CCD experiment was proposed to optimize TPC and viscosity and obtained a total of 13 experimental designs. The model results suggested by RSM-CCD are quadratic models. The result showed the optimization of the supplemented milk using a concentration of 2.837% hydrolyzed bovine collagen and PEF processing time of 116.369 seconds were the optimal designs with the desirability value of 0.809. Validation results using three repetitions produced an average TPC of 3.38 log CFU/mL  and viscosity results of 4.56 mPas. Under these conditions, the error rate value of both responses is less than 5%, indicating that the model optimization can be accepted.

Abstract

This work represents a comprehensive analysis of pedada fruit (Sonneratia caseolaris) as a less desirable fruit, but valuable content such as pectin which obtained through extraction using microwave assisted extraction (MEA) method. Pectin is a water-soluble fiber widely used as a functional component in the food and pharmaceutical industry. The analysis focuses on the comparison profile of pectin from pedada fruit and Kepok banana peel. In addition, the effect of the concentration of the extracting solvent on the methoxyl levels of pectin was also evaluated using the chemometric method (partial least square (PLS) and principal component analysis (PCA)). PLS was performed to determine the methoxyl content which plays a role in determining the pectin type. While PCA was to determine the pectin classification pattern based on the fruit supply location and the extracting solvent. The results showed that the PLS of extracted pectin of pedada fruit and Kepok bananas peels showed an R2 value of 1. This means that the pectin data model of each sample using the MAE method was in good classification. In addition, the PCA results show that the pectin extraction data plots are close together between samples in the quadrant, indicating the same characteristics and quality of pectin.

Abstract

Oil palm empty fruit bunches (OPEFBs) are highly abundant in Indonesia and have been highlighted as a potential feedstock for bioethanol and xylitol production. However, the efficacy of the fermentation technology to convert OPEFBs to bioethanol and xylitol, either in partial (i.e. mono-production) or integrated (i.e. co-production) process, still needs further improvement. This study aimed to evaluate the partial and integrated process for xylitol and bioethanol production from OPEFBs.  In the integrated process, the remaining solid residues after xylitol extraction are used as feedstock for bioethanol due to their high cellulose compounds. This solid residue is more susceptible to be degraded by cellulase enzymes into glucose and further transformed into bioethanol. In the partial process of xylitol production, xylanase enzyme was used to hydrolyze xylan into xylose, which was then converted into xylitol using Debaryomyces hansenii. While in the partial process of bioethanol production, the hydrolysis of cellulose in the OPEFB into glucose was carried out using cellulase enzymes, followed by fermentation using Saccharomyces cerevisiae. The results show that the partial process produced xylitol yield (Yp/s) of 0.10 g-xylitol/g-xylose, while bioethanol at yield (Yp/s) of 0.32 g-bioethanol/g-glucose, respectively. The integrated process generates xylitol yield (Yp/s)of 0.298 g-xylitol/g-xylose, with bioethanol yield from the remaining solid at 0.051 g-bioethanol/g-OPEFB (or 0.078 g-bioethanol/g-glucose). These findings, therefore, confirmed that the integrated process of xylitol with bioethanol production might offer higher efficacy of OPEFB utilization into high value-added products.

Abstract

Coal ash, such as fly ash (FA) and bottom ash (BA) is mostly generated from a Coal-fired Steam Power Generation (PLTU) process. An increase in the number of PLTUs in Indonesia is proportional to the high volume of FA and BA generated, causing adverse environmental impacts if not properly treated. Various studies have highlighted the potential valorization of FA and BA, including building materials, cement ingredients, concrete, and growing media. This study aimed to evaluate the potential use of FA and BA as a growing media and to explore the potential future application for reclamation of heavy-metal-contaminated (or ex-mining) land. The results showed that composting FA with blackwater sludge (BWS) and rice straw (RS) produced compost that complied with the targeted standard. The addition of FA, BA, and composted FA in the growing media impact the growth and Zn adsorption ability of the dwarf elephant grass (Pennisetum purpureum cv. Mott). However, the composted FA has superior performance in general as a growing media. The future estimation of the application FA and BA combined with domestic waste (blackwater and greywater) for reclamation of ex-mining land is proposed. By integrating the phytoremediation ability of the grass plants and the biorefinery approach, the proposed future estimation may provide a sustainable valorization pathway of FA and BA for heavy metal-contaminated or ex-mining land reclamation. Thus, transforming FA and BA as a component of growing media could reduce the potential risk of heavy metals distribution into the food chain and the surrounding environment.

Abstract

Nutmeg essential oil (Myristica fragrans) is susceptible to deterioration and chemically unstable when exposed to the environment, resulting in a loss of bioactive compounds and the development of off-flavors. Microencapsulation is then used to enhance shelf stability and nutritional value. This study aimed to attempt the nutmeg essential oil encapsulation, utilizing the spray drying technique by analyzing the effect of emulsion parameters. An array of process parameters including wall material content (7, 8, and 9%), the mass ratio of carrageenan to soy protein isolate (1:2, 1:1, 2:1), and concentration of essential oil (25, 50, and 75%) were thoroughly investigated. The results showed that almost all parameters significantly influence (p < 0.05) on determining emulsion and powder quality. The microencapsulation process with a mass ratio of carrageenan to soy protein isolate of 1:2 gave better microcapsules characteristics than other powders. The microencapsulation process that was performed with a solid content of 7% as wall material and nutmeg essential oil at the concentration of 25% as core material showed the best performance, resulting in the highest solid yield (83.33±0.37%) with good emulsion characteristics (i.e. stability, viscosity, and diameter droplet) and powder properties (i.e. moisture content, total solid, hygroscopicity,  and color).

Abstract

The world is moving towards clean energy, especially since the Paris Agreement in 2016. Indonesia is no exception, which must reach 23% of its total energy mix usage from renewable energy sources by 2025, as stated in President Regulation No. 22/2017. Biomass as a renewable energy source can be used as a co-firing fuel for power plants based on its calorific value. This study discusses some of the most important characteristics needed in co-firing fuels, including slagging, fouling, and abrasion, using palm empty fruit bunch (EFB), rice husk (RH), and EFB-RH blended with the composition of 5%, 15%, 25%, and 35% on low-rank coal (LRC) and bituminous coal (BTC).  The results showed that the addition of biomass on BTC has no significant effect on the slagging and fouling potential. Conversely, the addition of biomass to LRC significantly reduced the potential of slagging and fouling with the composition of up to 35% biomass which has EFB up to 20%. For blends with 75% of LRC and 25% of biomass blends, only biomass blends with 100% RH can be considered from the aspect of slagging and fouling risk. From potential abrasion characteristics, the addition of biomass on two types of coals did not show any problem for all compositions studied.

Abstract

Coleus tuberous (local name: kentang hitam/black potato) is widely available in Indonesia. Commonly, black potatoes are only boiled and made into side dishes. Black potatoes have the potential to be the ingredient of functional foods. However, black potatoes can only be harvested once a year. Therefore, a low moisture form (flour) storage is required for longer shelf life. Research on physicochemical and functional characteristics of black potato flour is expected to widen the use of black potato flour as raw materials in various food products. This study was aimed to analyze the chemical, physical, and functional  characteristics of black potato flour originating from Sunthi (Jaten), Begal, and Kopenan Forest villages in East Java, Indonesia. All the measurements were carried out with three replications and analyzed using one-way ANOVA, then followed by the Tukey test to find the difference from each sample at a 0.05 significance level. The correlation analysis and principal component analysis were also subjected to study the relationship between each character of the samples. The result indicated that the tuber and starch have relatively high ash, amylose, and total phenol concentration. Several high correlations were found between the characteristics of the black potato flours. One of the high correlations was the water absorption index with starch, amylose, and total phenolic content. The principal component analysis (PCA) also found that the three samples were loading differently in the score plot. Two first principal components (PCs) were the contributing factor for 100% of the differences.

Abstract

As human awareness increases with healthy consumption patterns, food products can be developed into functional foods, one of which is white bread with the addition of ginger and cinnamon. Ginger and cinnamon have phenolic compounds that act as an antioxidant, but the addition in white bread affect the physicochemical and rheological properties of the dough and the loaf volume of white bread. This study aimed to determine the optimum concentration of ginger and cinnamon to produce white bread with the highest total phenol, antioxidant activity, and loaf volume. The research was established with the Response Surface Methodology method using Central Composite Design withtwo factors: concentration of ginger and cinnamon. Minimum and maximum concentrations used for ginger and cinnamon were 1-3% (flour-based) and 2-4% (flour-based), respectively. The optimum result obtained from the program was ginger and cinnamon, at concentration approximately 2.68% and 4% (flour-based), with total phenolic content of 47.90 mgGAE/100g, antioxidant activity of 32.30%, and loaf volume of 154.29%. Optimum white bread had lower loaf volume than controlled white bread.

Abstract

Macroalgae as the marine renewable biomass has great potential for production of bioenergy and bioproduct with integrated biorefinery concept. However, high lignin content may hinder the valorization. Same conditions applied for the macroalgae in Indonesia which has the great opportunity to explore more in the bioenergy field. This study aimed to investigate potential application of macroalgae as substrates for bioenergy production, specifically with anaerobic digestion (AD) technology. Anaerobic digestion as the one of the ways to transform macroalgae into biogas. This review analyses the latest study’s results from the view of composition, degradation, and the biorefining pathways. The biomass is constructed from lignocellulose compounds and have thick cell wall that be the main drawbacks for the biochemical conversion technology. Various enhancement pathways have been studied i.e., pretreatment methods to enhance the accessibility for microorganisms, reduce the outer cell wall thickness, and co-digestion with addition of other substrates to balancing the nutrition and providing the stable condition for AD system. In term to have more feasibility from economic view, the strategy is put in the biorefinery concept to have more valuable-added products. The decrement of energy input, higher of energy output and yield of outcome along with some products being produced are expected to gain from the proposed ways. Those information will provide new research directions and solutions for converting Indonesia marine macroalgae using AD technology.
