“…A new insoluble vegetal fibre has been developed in order to adsorb the OTA present in liquid food products or, in the case of beer, present during the brewing step [273]. Currently, the most promising adsorbent materials are modified zeolites (reduction up to 72%) [274][275][276][277].…”

Abstract:Mycotoxins are toxic secondary metabolites produced under special conditions of moisture and temperature by aerobic, microscopic fungi that can colonize a variety of foods from before harvest up to consumer use. Contamination of beverages, including that of apple juice by patulin and coffee, beer and wine by ochratoxin A has gained worldwide interest in recent years with the revelation of the effect of these toxins on human health. Patulin and ochratoxin A, which are produced by species of Penicillium, Byssochlamys and Aspergillus, pose the greatest threat to human health and are subject to government regulation in juices and beverages worldwide. This review provides an overview of the prevalence of these mycotoxins in beverages and control methods which help in establishing and carrying out proper management strategies. A detailed investigation on OPEN ACCESSToxins 2010, 2 230 contamination of juices and beverages by toxic compounds helps to provide safe products for consumption and export, and they allow us to prioritize future research efforts.

Quality requirements for the product assortments, obtained from a large number of non-metallic mineral raw materials, are defined, and above all, they have the defined particle size. Are the quality requirements for zeolite assortments defined? Searching for the answer to this question, an internet research was done. The web pages of the most significant producers of materials based on natural zeolite were studied as well as the papers of a large number of prominent researchers whose experiments are focused on the natural zeolite. This paper presents the findings primarily with the aspect of particle size as the quality parameter of zeolite assortments. Based on this analysis, it is considered that it should define the quality requirements of zeolite assortments, especially the particle size for each product. In fact, it is important to know the particle size in mineral processing in order to choose less expensive procedure for obtaining the finall product.

“…De forma geral, são substâncias caracterizadas por uma estrutura complexa, com uma grande diversidade de grupos funcionais (Figura 1) (Tomašević-Čanović et al, 2003). As estruturas variam de simples anéis heterocíclicos com massa molar de 50 g/mol até grupos de 6 a 8 anéis heterocíclicos dispostos irregularmente com massa molar acima de 500 g/mol (Pitt, 2000).…”

RESUMO.Micotoxinas são substâncias tóxicas produzidas pelo metabolismo secundário de fungos filamentosos e capazes de desencadear uma série de problemas relacionados à produção agropecuária e à saúde pública. O monitoramento destes agentes tóxicos é necessário, devendo-se levar em consideração para realização de tal atividade a diversidade das amostras que são colhidas, os tipos distintos de micotoxinas, bem como a distribuição não uniforme destes contaminantes. A escolha adequada dos pontos de amostragem, bem como do uso de uma metodologia eficaz que considere os possíveis interferentes e contemple os níveis de detecção esperados também são fatores indispensáveis para o sucesso e confiabilidade das análises realizadas. Com o intuito de atender às exigências da legislação brasileira para micotoxinas, vários alimentos deverão ser analisados, para isso, o conhecimento de procedimentos para colheita de amostras e análises laboratoriais são importantes para pequenos produtores e para indústria de alimentos. Considerando que a aplicação adequada destas metodologias não apenas pode aumentar a produção agrícola e sua consequente lucratividade, como também propiciar a segurança alimentar dos diversos produtos brasileiros destinados às dietas humanas e/ou animais, esta revisão visa descrever as principais metodologias existentes no Brasil para colheita de amostras e análise de micotoxinas, assim como abordar os principais métodos analíticos existentes para detecção e quantificação destes contaminantes. Palavras chave: Alimentos, amostragem, análises laboratoriais, metodologias analíticasProcedures for sampling and laboratory tests of mycotoxins existing in human and animals feed ABSTRACT. Mycotoxins are toxic substances produced by the secondary metabolism of filamentous fungi and able to trigger series of problems related to agricultural production and public health. Thereby, monitoring of toxic agents is absolutely necessary and must be taken into account for the performance of such activity the diversity of samples to be collected, the different types of mycotoxins as well as the non-uniform distribution of these contaminants. Proper selection of sampling process as well as the use of a effective methodology will eliminate the trace of interference in order to have a successful analyses. Thus, in order to meet the requirements of the current Brazilian legislation for mycotoxins, various foods should be analyzed for this, knowledge of procedures for sampling and laboratory analyzes are of fundamental importance to both small producers and for the food
