Assessing the food control system in Indonesia: A conceptual framework

This study develops a conceptual framework as a basis for quantitative assessment of food control system in Indonesia to achieve food security and improve public health. Currently, an assessment of the food control system in Indonesia has not been comprehensively carried out. In developing a conceptual framework for a quantitative assessment model in the form of an index for a food control system, a desk study and expert panel discussion were conducted to analyse the existing regulations and policies in effect in Indonesia, the relevant Food and Agriculture Organization and World Health Organization guidelines and previous related studies. The food control index model was designed based on input and resources, interactions with stakeholders, science/knowledge base and continuous improvement, and control functions. The indicators are adjusted to the context of the food control system in Indonesia, including the dimension of interaction with stakeholders, which focuses on the national scope, because the model is prepared starting at the provincial level and forms an aggregate at the national level. This model is still in the initial stage of research and forms the basis for the preparation of subsequent instruments. The proposed conceptual framework could become the foundation needed for the development of the index, which can then be used as the basis for subsequent policy interventions to improve food security. Ultimately, this model could also increase food security and the competitiveness of food products in national and global markets. • Develop a conceptual framework for assessment the food control system in Indonesia. • Currently, the assessment has not been comprehensively carried out. • The indicators are adjusted especially focuses on the national scope. • The framework could become the foundation needed to develop food control index.

The purpose of the study is to analyze the current state, existing obstacles and prospects for growing and using energy crops in Ukraine. Different aspects such as the availability of unused land for cultivation, technical and economic indicators of relevant projects, as well as the results of life cycle assessment of heat production from energy crops are taken into account. Research methods include analysis and processing of official statistics on the area of land of different categories in Ukraine; performance of life cycle assessment for growing energy crops for heat production in terms of energy efficiency and reduction of greenhouse gas emissions; carrying out of feasibility study of respective projects. Results of the study show that there are up to 4 million hectares of unused agricultural land in Ukraine annually, which can be used for growing energy crops without creating competition for food production and without violating the criteria of sustainable development. The life cycle of projects for growing perennial energy crops for heat production has high energy efficiency, and the value of greenhouse gas emissions reduction depends significantly on the distance of transportation of biofuels. However, projects for the cultivation of such energy crops as willow, poplar, and miscanthus have economic indicators on the verge of profitability, and therefore may not be attractive enough for investors. Conclusions. Growing and using energy crops is one of the most promising sectors of bioenergy in Ukraine. The advantages of this area are the ability to obtain all types of biofuels (solid, gaseous, liquid biofuels) to replace traditional energy sources, a positive impact on soil (increase in organic matter, phytoremediation of contaminated lands) as well as local economic development and job creation in the regions. To improve the economic performance of the relevant projects, it is necessary to introduce a state subsidy for the cultivation of energy crops at the level of 20-24 thousand UAH per ha, depending on the type of crop.

Маркетинговые исследования потребительских предпочтений для разработки обогащенных сывороточных напитков

Currently, to ensure high competitiveness of food products, manufacturers need to achieve not only their compliance with the requirements of regulatory and technical documentation, but also to develop conceptual ideas and solutions that take into account the wishes of consumers, anticipate and quickly respond to changes in their quality requirements. In this regard, determining consumer preferences is an important step in the development of new products. This article presents the results of a consumer preference study used to develop an enriched whey drink. At the first stage of the research, the target portrait of the consumer of fortified whey drinks was determined by the method of a survey in the form of a questionnaire. By gender and depending on the age of the respondents, dairy products are preferred by the ages of 26 to 35, with the majority of them being two groups: «workers» (32.9%) and «specialists» (29.6%). The most preferred type of dairy products are fermented milk drinks (71.2% of responses), however, it should be noted that the diet of a modern consumer includes whey products. The majority of respondents chose «fruits and berries and their processed product» as a fortifier (38%), «grains and their products» (34%), «biologically active additives» (16%) and 12% of the respondents chose «nuts and oilseeds». At the second stage of the research, the assortment of whey drinks presented in the retail. It has been established that the range of whey drinks is represented by three large producers, but there are no drinks from local producers enriched with local raw materials, the development and production of which is a promising and relevant research area.

Analysis of carbon monoxide production in methanol steam reforming reactor for generating hydrogen

Seeking renewable energy sources has been a very important aspect in the development of human society, with many authors regarding hydrogen as a rather promising energy source. There are several forms of obtaining hydrogen, including steam reforming of hydrocarbons, alcohols, and ethers. Some characteristics of methanol, such as processing at mild temperatures from 250 to 350oC under atmospheric pressure and production from biomass – no competition for food production – have distinguished it from other alcohols for steam reforming. The great disadvantage of this technology when applied in proton exchange membrane (PEM) fuel cells is that the process of methanol steam reforming involves not only hydrogen and carbon dioxide, but also the production of a small amount of carbon monoxide, which is sufficient to affect the functionality of the fuel cells. This work presents the characterization of the catalyst HiFUEL R120 and shows how water/methanol molar ratio in the feed stream of an integral methanol steam reforming reactor influenced the conversion and the hydrogen selectivity in relation to carbon monoxide. This made it possible to identify the best operational conditions for lowering carbon monoxide content in the reactor effluent, avoiding the use of a CO purification unit.
