Abstract

This paper presents study towards Malaysian local oranges peel to predict Brix i.e. sweetness level using a monopole sensor for its relationship on reflection coefficient (S11), Brix and moisture content (%m.c). Analysis was carried out in order to support hypothesis that oranges skin or peel can determined its flesh sweetness non-destructively. The effect on reflection coefficient (S11) and its relation with Brix are measured towards 30 sample of Malaysian local oranges that freshly plucked from local oranges farm. The unique design of a holder for local oranges that is made of nylon is enclosed in this project contributed to its invention. The experiment test bed was set up based on standard dimension of small monopole sensor available in the market.
