“…Recently, in particular, with the decreasing average daily caloric intake and the greater prominence of high energy foods, the vitamin content of the vegetables consumed has become of greater importance in balancing the U.S. diet. Earlier studies still relied upon as valid, (Clifcorn, 1948;Cameron et al, 1955) clearly show vitamin loss during the commercial canning of a large number of vegetables, and the amounts found in different samplings of the same product vary greatly. It has been known that the loss of vitamins is affected by the type of vegetable as well as the preprocessing and processing conditions and that variation may be due to differences in cultivars of raw materials used, and to differences in the cultural practices under which the products were grown (Harris and Karmas, 1975).…”

“…FBP 754 1-13 2 food and bioproducts processing x x x ( 2 0 1 6 ) xxx-xxx of retorts for canning, the agitation retorts were introduced in 1920s with the agitation mechanism based on horizontal axial rotation (Ates et al, 2014). Vertical rotation of the cans was later introduced with the end-over-end rotation principle (Clifcorn et al, 1950). Introduction of agitation mechanism in canning for liquid or liquid-solid particles containing food products was the result of a certain disadvantage of the static retort systems (Rosnes et al, 2011).…”

“…Concluiu que processos de aquecimento rotativos são vantajosos em função da redução do tempo de processo, com aumento da retenção de nutrientes e conseqüentes economias de processo e possibilidade de aumento da produção. Clifcorn et al (1950) estudaram o mesmo tipo de agitação "cabeça sobre cabeça" em latas contendo água com espaço livre fixo de 8 mm. As variáveis era a rotação e a distância do centro da massa ao eixo de rotação.…”

“…A atividade diastásica nesta forma de agitação passa a limites abaixo dos permitidos pela legislação, de 7,20 unidades Gothe, ou seja, é reduzida em 20% do valor do ensaio "cabeça sobre cabeça". Clifcorn et al (1950) realizaram ensaios com latas 400x700 e 603x700, e compararam com os resultados obtidos da agitação das mesmas embalagens em rotação "cabeça sobre cabeça" e rotação axial. Confirmaram o desempenho superior no caso da agitação "cabeça sobre cabeça", particularmente em rotações não muito altas.…”
