Karakteristik Fisikokimia dan Sensoris Kopi Arabika Menoreh dengan Teknik Seduhan Cold Brew

Coffee is one of the most widely distributed and consumed beverages in the world. In general, coffee is brewed using hot water, but as the coffee industry develops, cold water also can be used for the coffee brewing process. This brewing technique is known as cold brew. There is little information regarding the characteristics of cold brew coffee. Therefore it is necessary to study the characteristics of cold brew beverages, especially with local Indonesian coffee as its main ingredient. This research used Menoreh Arabica coffee as its main research object. This study aimed to determine the physicochemical and sensory characteristics of Menoreh Arabica coffee with cold brew brewing techniques. This research begins with roasting coffee into three types, which is light (T = 193 oC, t = 5 minute), medium (T = 208 oC, t = 7 minute), and dark (T = 223 oC, t = 13 minute). Furthermore, the coffee is grinded into two types grind size (medium and coarse). Samples of cold brew formulation were made with an extraction time of 8 hours. The sensory analysis is conducted based on the SCA method. Sensory data analysis was done to determine the three best formulations according to roast profiles, continued with the physicochemical analysis. The best cold brew sample obtained from this research was medium-coarse Arabica Menoreh coffee, with the highest sensory parameters values in aroma, acidity, aftertaste, and sweetness. The value of pH, chlorogenic acid, and some organic acids affect acidity. Lactic acid affects body value, and caffeine levels were relatively stable in each sample. This research result can be used as a reference for product diversification of Arabica Menoreh coffee.

Amaranth-oat composites were developed using gluten free amaranth flour containing essential amino acids and minerals with oat products containing β-glucan, known for lowering blood cholesterol. Amaranth flour and oat bran concentrate (OBC) composites (1:4) were processed using different technologies, including dry mixing, baking, steaming, cold wet blending, and high speed homogenizing (Polytron PT6000) with cold water or hot water. The results showed that water holding capacities, pasting, and rheological properties were dramatically increased by wet blending, Polytron with cold water, and Polytron with hot water followed by drum drying. The processing procedures created dissimilar physical properties that will enhance the application of ancient grains and oat for functional foods that are suitable for people who are gluten-intolerant. In addition, the dietary fiber contents of composites were increased by the incorporation of OBC. The composites can be inexpensively prepared and processed. The new healthful products will be affordable for people who suffer from celiac disease or gluten-intolerant. These innovative gluten-free functional food products will help millions of gluten sensitive consumers enjoy heart-healthy functional foods.

Expert Meeting

Purpose – This paper is based on a presentation given at the international World Heritage expert meeting on criterion (vi) held in Warsaw, Poland, in March 2012. Results were updated and adapted to scientific standards. The purpose of this paper is to understand the associative dimension in World Heritage by looking at the evolution and application of criterion (vi). Design/methodology/approach – For this paper, historical and qualitative approaches were combined. An understanding of the evolution of the criterion (vi) wording was gained through historical analysis and the consultation of relevant World Heritage statutory documents. A selected number of criterion (vi) statements were analyzed in qualitative terms. Results were then discussed in relation to the evolution of criterion (vi) wording and the understanding of pertinent World Heritage concepts. Findings – Criterion (vi) holds a special position. It addresses an associative dimension of cultural World Heritage sites. Due to its special character, its wording was subject to several changes. While its wording became ever more flexible, this development has not fostered the inscription of exceptional cases or the equal use of cultural associations. An inconsistent interpretation has also weakened the concept of Outstanding Universal Value. Research limitations/implications – Only inscriptions were taken into consideration. They usually have a World Heritage Committee approved criterion (vi) statement. Limitations to this research result from this restriction. Originality/value – The paper represents a comprehensive study of the application and interpretation of criterion (vi) that combines the understanding of the evolution of the criterion’s wording with the analysis of a large number of World Heritage inscriptions. It is of interest to the World Heritage community and contributes to the World Heritage discourse.

Abstract Purpose – The situation in the field of gambling is changing due to the rise of Internet and Mobile gambling. In general gambling consumption is increasing every year, but the distribution of consumption has radically changed from Land Based gambling to Remote gambling. The purpose of this article is to present an overview of the world gambling industry and a specific overview in Austria, Croatia, Italy and Slovenia in order to find some main similarities and differences in observed period. Design/Methodology/Approach – The main research question is How important is gambling for the involved countries and what proportion of the national GDP does the gambling revenue account for? This paper presents the analysis of five statistical databases for the last sixteen years in order to find out some patterns, cyclical or seasonal features or other significant information that allows us to do forecasting of the future revenue with a certain degree of accuracy. We have systematically searched and collected data from the World Bank and the National Statistical Offices websites of the given countries. Statistical methods were used for benchmark analysis, while Box and Jenkins approach and ARIMA modelling were used for forecasting. Findings – The smallest increase was recorded in Slovenia and the largest in Italy. The same effects were also observed in the GDP of these countries. Thus, the state budgets of Croatia and Italy are increasingly dependent on gambling taxes. It also has negative wages. The gambling addictions among the locals have become more frequent as well. Originality of the research – The article shows the forecasts of the gambling revenue and its share in the GDP by 2027. We want to alert decision makers to adopt appropriate policies. States need to rethink their views on gambling and the excessive dependence of the state budget on gambling taxes. This is the first time a single comparative analysis of these countries and the above mentioned forecast has been conducted.

A dificuldade em suprir a demanda de proteína de origem animal de excelente valor biológico para a população humana é uma das maiores preocupações do nosso século. De acordo com a FAO, a atividade pesqueira (pesca extrativa e aquicultura), será uma das principais atividades responsáveis pela segurança alimentar do planeta, com previsões de produção de proteína de origem animal para a próxima década maior do que o setor de animais de abate (carnes bovinas, suínas e aves). A utilização de recursos pesqueiros subutilizados com potencial para explotação poderá assegurar a manutenção da oferta primária de matéria prima no mercado interno local e/ou regional, e inibir oscilação de preços, como a prática da mariscagem. Neste contexto, o presente artigo de revisão tem por objetivo evidenciar o potencial da Anomalocardia brasiliana para explotação e processamento contribuindo para o fortalecimento desta cadeia produtiva no segmento artesanal e diversificação de produtos no mercado brasileiro.The production of clams and its potential for development of new products based on fish Abstract: The difficulty in supplying the animal protein demand of great biological value for the human population is a major concern of our century. According to the FAO, the fishery (extractive fishing and aquaculture), will be one of the main activities responsible for food safety in the world, with animal protein production forecasts for the next decade longer than the slaughter of animals sector (beef, pork and poultry). The use of fishing resources with underutilized potential for exploitation can ensure the maintenance of primary supply of raw materials on-site domestic and / or regional, and inhibit movement of prices, as the practice of shellfish. In this context, the present review aims to highlight the potential of Anomalocardia brasiliana to exploitation and processing contributing to the strengthening of this production chain in the craft segment and product diversification in the Brazilian market.
