Processed sebastan plum cordia balls were made of the fruits of sebastan plum cordia. sebastan plum cordia can maintain more original flavor as they were picked up and processed that day. If not that day, calyxes of sebastan plum cordia should be kept till the next day waiting to process. Otherwise, it would lose commercial value due to oxidative browsing and case hardening on the surface and mucus coagulation caused inside.

破布子最大用途是采取果实加工制造成破布子丸，其原料必需是当天采收、当天加工处理制成破布子丸，较能保有天然香味；若不能当天处理，应於采收时不去除果蒂，待翌日去除果蒂后即行处理，否则去除果蒂后留置隔天，原料即氧化褐变，果实表皮变硬，里面粘液凝结，失去商品价值。
