Storage stability of cashew apple juice preserved by hot fill and aseptic processes

Cashew (Anacardium occidentale L.) apples from Pacajus, Ceará State, Brazil, were processed into high pulp content juice. The juice was packed either by hot fill or an aseptic process and evaluated for physical, physical-chemical, and sensorial changes during a 12-month storage period at room temperature. The results indicated that pH, soluble solids, total acidity, total sugar content and color did not change significantly during storage nor were affected by the type of filling. The sensorial analysis showed that juice acceptance remained high throughout the storage period regardless of the filling system. Differences in juice viscosity persisted between both processes.

Estabilidade do suco tropical de acerola (Malpighia emarginata d.c.) adoçado envasado pelos processos hot-fill e asséptico

Este trabalho objetivou avaliar a estabilidade do suco tropical de acerola adoçado, elaborado pelos processos hot fill (garrafas de vidro) e asséptico (embalagens cartonadas), com relação às alterações químicas e físico-químicas (pH, sólidos solúveis totais, acidez total titulável, cor, açúcares redutores, não redutores e totais), sensoriais e microbiológicas, durante 350 dias de armazenamento em condições similares às de comercialização (28 °C ± 2 °C). Ao final do experimento, constatou-se que as amostras de suco de ambos os processos mantiveram uma adequada estabilidade microbiológica. O suco do processo hot fill teve maior aceitação global, enquanto o do processo asséptico manteve, ao final dos 350 dias, a aceitação inicial. As amostras do processo asséptico apresentaram inicialmente melhor sabor em comparação com as do processo hot fill, no entanto, as do processo hot fill mantiveram o sabor estável, enquanto o sabor do suco do processo asséptico teve menor aceitação ao longo do armazenamento. Ainda foram observadas, alterações químicas e físico-químicas nos sucos de ambos os processos. Em geral, o processo hot fill foi o mais eficiente em manter a estabilidade do suco.

Chemical composition and nutritive value of hot pepper seed (Capsicum annuum) grown in Northeast Region of China

Chemical composition and nutritive value of hot pepper seeds (Capsicum annuum) grown in Northeast Region of China were investigated. The proximate analysis showed that moisture, ash, crude fat, crude protein and total dietary fiber contents were 4.48, 4.94, 23.65, 21.29 and 38.76 g/100 g, respectively. The main amino acids were glutamic acid and aspartic acid (above 2 g/100 g), followed by histidine, phenylalanine, lysine, arginine, cysteine, leucine, tryptophan, serine, glycine, methionine, threonine and tyrosine (0.8-2 g/100 g). The contents of proline, alanine, valine and isoleucine were less than 0.8 g/100 g. The fatty acid profile showed that linoleic acid, palmitic acid, oleic acid, stearic acid and linolenic acid (above 0.55 g/100 g) as the most abundant fatty acids followed lauric acid, arachidic acid, gondoic acid and behenic acid (0.03-0.15 g/100 g). Analyses of mineral content indicated that the most abundant mineral was potassium, followed by magnesium, calcium, iron, zinc, sodium and manganese. The nutritional composition of hot pepper seeds suggested that they could be regarded as good sources of food ingredients and as new sources of edible oils.

Global instability of currencies: reasons and perspectives according to the state-corporation hegemonic stability theory

This paper analyses reasons of the instability of the world monetary system. The author considers this problem from historical and contemporary perspectives. According to presented point of view banknotes and electronic money which replaced gold and silver coins in popular circulation are the most important reason of the instability. There are also proven positive and negative consequences of money instability. Reforms of the world monetary system need agreement within the global collective hegemony of state-powers and transnational corporations.

From gold money to fictitious money

ABSTRACT In the nineteenth century, money appear primarily as gold. In the twenty-first century, it appears as strictly fiduciary money. It is known that Marx said very clearly that the golden money was the effective basis of the monetary and credit system. Had the historical development finally shown that his theory of value and money would be false? Marxists have struggled continually with this problem. This paper tries to show that exist a simple and good answer to this crucial question. It comes just developing a little the dialectics of commodities and money found on Marx's Capital.
