| O julgamento da qualidade de produtos vegetais provenientes de diferentes tipos de plantio encontra sempre os mesmos problemas: Segundo SCHUPHAN (1961) a qualidade de um alimento é determinada por três características principais: a qualidade externa (por exemplo variedade comercial), o valor de consumo (ou seja manufatura e industrialização) e a qualidade biológica, a qual exprime o balanço dos nutrientes. A soma simples dos efeitos dos nutrientes não é porém suficiente para determinar a qualidade, uma vez que somente uma parcela da planta é levada em consideração, problema este que já foi muito discutido (entre outros: KLETT, 1968; SCHORMÜLLER, 1974). Paralelamente surgem com frequência tendencias conflitantes nas pesquisas, nas quais se objetiva uma... |

| Die Qualitätsbeurteilung pflanzlicher Produkte aus unterschiedlichen Anbauverfahren stößt immer wieder auf die gleichen Probleme: Nach SCHUPHAN (1961) setzt sich die Qualität eines Nahrungsmittels aus drei Haupt-eigenschaften zusammen: Äußere Beschaffenheit (z.B. Handelsklassen), Gebrauchswert (d.h. technische Verarbeitbarkeit) und biologischer Wert, welcher die Addition aller wertgebenden abzüglich der wertmindernden Inhaltsstoffe darstellt. Diese Summation der Inhaltsstoffe kann zur Qualitätsbeurteilung jedoch nicht ausreichen, da immer nur ein Bruchteil der Pflanze und nie die Pflanze als Ganzheit gesehen wird, ein Problem, welches schon des öfteren diskutiert wurde (u.a. KLETT, 1968; SCHORMÜLLER, 1974). In Untersuchungen, welche Rückschlüsse auf die... |

| Adequately assessing the quality of food grown with different cultivation methods is a constant problem. According to SCHUPHAN (1961), food quality consists of three main characteristics: grading, technological quality and nutritional quality. The latter involves the ratio between beneficial and harmful substances. Yet it is obvious that more than merely summing various substances is needed to assess the quality of food properly. This problem has been previously discussed by SCHORMÜLLER (1974) and KLETT (1968). A concept of quality that embraces the plant as a whole (and the internal equilibrium of the individual components) requires bringing together the results of multiple investigations in an integrated accounting that registers even slight... |
