The main objective of this study was to determine the effect of green marketing as a mediating variable on increasing green knowledge variables on increasing consumer buying interest in eco-friendly products. Questionnaires were distributed to 110 Starbucks Coffee consumers in Bandung, which were analyzed by descriptive analysis to describe general characteristics of the respondents. The Structured Equation Model – Partial Least Square (SEM-PLS) analysis was also used to confirm the theory that there is an influence of green marketing variables as a mediating variable on increasing green knowledge on consumer buying interest in green products. The results showed that consumers of Starbucks Coffee in Bandung were dominated by women in their early adulthood who worked as private employees with moderate income. The implementation of the green marketing strategy by Starbucks is expected to maximize customer service in accordance with the description of consumer characteristics with the green marketing strategy implemented by Starbucks Coffee. The provision of green knowledge that affects the increase in consumer purchase intention of green products can be further improved positively and significantly through the application of green marketing strategies as a mediating variable.

The eucalyptus oil factory (PMKP) Sukun Ponorogo is an industry with complex supply chain activities, starting from the raw material’s procurement, production processes, distribution, and reverse logistics. Some of these activities may result in environmental problems. Therefore, measurement of its supply chain management (SCM) performance related to environmental conditions is critical. The green supply chain management (GSCM) concept can help the company to assess the supply chain's performance conditions that could harm the environment. This study aimed to assess the current SCM and measure its performance, as well as to evaluate the potential implementation on GSCM in the PMKP Sukun Ponorogo. The analytical network process (ANP) was used in this study, consisting of 36 key performance indicators (KPI) from five categories of plan, source, deliver, make, and return. The study results show that all KPIs from the responsiveness dimension in the deliver category have the lowest weight, thus require priority for improvement. The results of the scoring system using the objective matrix (OMAX) method indicated two KPIs were in the red category (or need improvement), including on-time delivery of raw materials to production site and the rejection rate of raw materials. This study suggested to improve the estimated delivery time for avoiding any delays during the production process. This improvement may support the company to continuously offer on-time production process and product’s distribution.

This research aimed to evaluate the effect of flow rate and processing time on the synthesis of high mono- and diacylglycerol (MDAG) from palm stearin-olein blend using high shear continuous stirred tank reactor (HS-CSTR). Glycerolysis-interesterification was performed at 120 ºC and flow rates of 6, 10, 14, 18, and 22 mL/min. Glycerol:oil ratio, stearin:olein ratio, NaOH concentration, and agitation rate were 1:5 (mol/mol), 60:40 (w/w), 3%, and 2000 rpm, respectively. The result showed that flow rate significantly affected MDAG concentration and the product's physical characteristics. The highest MDAG was obtained at a flow rate of 6 mL/min. MDAG concentration, slip melting point (SMP), melting point (MP), hardness, emulsion capacity, and stability were 60.36 ± 1.61%, 42.3 ± 0.01 ºC, 43.3 ± 0.06 ºC, 6.04 ± 0.32 N, 87.6 ± 1.75 % and 91.8 ± 2.99 % respectively. An increase in residence time, which means flow rate decreased, increased MDAG, SMP, MP, hardness, emulsion capacity, and stability of the product. Processing time did not significantly affect MDAG concentration and the product's physical properties. It means that acylglycerol concentrations and physical properties of the product did not fluctuate significantly during the process. Thus, it confirmed that the continuous process was stable and reached a steady state throughout the process.

Agroindustrial wastes represent a rich and underutilized source of valuable minerals. Because the amount of biomass wastes generated by the agroindustry is increasing and the demand for sustainability is arising, there is a growing need for improving agroindustrial waste utilization and valorization. One of the major industrial interests has been obtaining silica from biomass wastes. The synthesis of silica from agroindustrial waste materials typically involves the use of high energy input for calcination or incineration and chemicals for extraction. To reduce energy consumption and chemical waste generation, we modified a sol-gel method to yield a by-product that can be used as a fertilizer. High purity silica was obtained from rice husk (95.1%), rice straw (91.4%), and corncob (95.9%). The silica particles were amorphous and white in color. The mean diameters of the silica particles obtained from rice husk, rice straw, and corncob were 72.4, 68.1, and 52.9 µm, respectively. The acid waste generated from the process was neutralized to yield potassium chloride. This by-product had mineral contents that could be used for inorganic fertilizer. In addition to supporting sustainability, the development of agroindustrial waste utilization methods is important for the establishment of inexpensive processes that are adaptable for large-scale manufacturing.

Orange-fleshed sweet potato (Ipomoea batatas) carotenoids were encapsulated in maltodextrin and whey protein concentrates by spray-drying to promote dispersibility in water and looked for the best encapsulant concentration in both encapsulants. The moisture content, wettability, hygroscopicity, color characterization, cold water solubility, and encapsulation efficiency were analyzed for encapsulant concentration of 10%, 20%, and 30% (w/v). The encapsulant concentration of 20% showed the best result with 6.09% moisture content, 11.07 hygroscopicity, 51 s wetting time, 94.50% cold water solubility, and 81.52% encapsulation efficiency for maltodextrin encapsulant. While whey protein concentrates encapsulant gave the result of 6.35% moisture content, 12.44% hygroscopicity, 148.8 s wetting time, 93.13% cold water solubility, and 82.02% encapsulation efficiency. The diffractogram from XRD showed that microcapsule had the amorphous phase dominant and indicated high solubility in water matrix. The microcapsule using maltodextrin encapsulant has smoother and more spherical morphology than microcapsule using whey protein concentrate encapsulant. The color characterization of 30% was lighter, less red, and less yellow than the others based on L*, a*, and b* value respectively. The carotenoid with 20% encapsulant concentration was well encapsulated enough and the addition of more than that did not produce significantly better results.

Cold infused technique is one of the brewing methods that potentially able to preserve coffee leaf tea functional properties. It is mainly attributed to the absence of heat treatment during its processes. However, without involving heat, the sensory quality of cold brewing tea is generally weak. To overcome this issue, it was hypothesized that water quality used for the brewing is important to govern optimum functional properties of Robusta coffee leaf tea and at the same time to maintain its sensory quality. In this current study, Response Surface Methodology (RSM) was applied by implementing Box-Behnken Design (BBD) to optimize both total phenolic content (TPC) and antioxidant activity by modifying length and temperature of cold brewing as well as its water and coffee leaf powder ratio. There were 3 different commercial drinking water used for brewing to represent 3 different hardness level of water. All optimum brewed coffee leaf tea was then sensorially evaluated by Rate All That Apply (RATA) method. It was found that level of water hardness is positively correlated to TPC but negatively correlated to brewing temperature as well as water and coffee leaf powder ratio. It was also found that the higher level of water hardness, both fruity and marine aroma tended to be more intense (p-value<0.05). Meanwhile the lower level of water hardness tended to enhance sweet aroma and astringent mouth-feel (p-value<0.05) of cold infused coffee leaf tea.

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.

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.","PeriodicalId":325722,"journal":{"name":"Advances in Food Science, Sustainable Agriculture and Agroindustrial Engineering","volume":" 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120834227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.
