Abstract
It has been clarified by many papers that alkyl benzene sulfonate (ABS) type synthetic detergent is not injurious to the health.
Under the food sanitary consideration, the authors made some experiments on food washing with ABS-detergent from the standpoint of domestic science.
In case of strawberry washing, the connections between washing procedure and “damage, ”“change in numbers of living organisms, ” and “residual amounts of ABS” was examined in this paper.
(1) It is found that the “damage” suffered from washing is more prominent by “rub bing” than “detergent” itself.
(2) Although the removal of living organisms on strawberry is very difficult by were washing with water, the washing with detergent removes them efficiently.
(3) The residual amounts of ABS on washed strawberry are affected by the condition but only 1-4 p. p. m. of ABS may remain on the strawberry in the case of usual application.
