芭樂果汁所含丙種維生素的放射效應及芭樂果實的放射保存的研究

作者:陳素貞

摘要：

藉Co⁶⁰之放射線的照射，以比較標準 ascorbic acid 和芭樂果汁內含有之 Vitamin C 之破壞情形，得知芭樂果汁含有Vitamin C 之殘存率，如同標準 ascorbic acid 一樣，若以 Vitamin C 破壞率比標準ascorbic為小。又知芭樂果實保存之最高劑量約在105 rad左右。

A Study on the Radiation Effect of Vitamin C in Guava Juice and Radiation Preservation of Guava Fruits

Author: Su-Chen Chen

Abstract：

Use γ ray of Co⁶⁰ (5000 curie) to coimpare the destruction of standard ascorbic acid and guava juice. The result of my experiment reveals that the destruction of Vitamin C in guava juice has the same tendency as ascorbic acid: if one makes a diagram of logarithm concentration (%) v.s. irradia-tion dose, a straight line may be found. The destruction of Vitamin C in guava juice is less than that of standard ascorbic acid.
The other result reveals that the most available irradiation dose to preserve guava fruits is about 105 rad.
