公司成立背景：
近年來臺灣甜柿栽種面積已近五千公頃，但產期集中於10-12月，卻難以冷藏保存，因此農家收入不佳、經常不合乎成本。為了解決甜柿產業窘境乃設立柿外桃園有限公司，期能為甜柿產業開拓出新出路。
首先，取得甜柿鮮果吉園圃認證，讓消費者食的安心。接著，研發冷藏技術延長保存期限，擴展外銷市場、穩定銷售管道。在加工方面選擇合格之優良廠商OEM，產出優質安全的產品，有效穩定甜柿物價、銷售量。更加強網路虛擬店面行銷，穩定提昇品牌形象。
核心產品：
公司主要產品包含甜柿脆片、甜柿茶、甜柿酒、甜柿麵條、甜柿醋、甜柿果凍、甜柿優格…等，更將相關經驗應用於在地特產「高接梨」，製成梨脆片、梨麵條、梨醋，更透過現代技術有效應用古早秘方開發出「冰釀梨汁」，協助在地梨農產銷。近期則將相關技術應用於「桂竹筍」，已成功生產出可常溫保存之「有機桂竹筍」。
未來發展方向：
公司成立至今曾獲得經濟部新創事業獎優質獎、縮減產業數位落差計畫優網獎、產品曾獲100大臺灣觀光特產認證、環保署綠色包裝優選、客家十大伴手禮…等。在國際機場、高鐵OTOP館，皆有展銷本店產品。未來將持續生產優質加工品、強化在地產業特色，朝向在地特色店發展，更將設立甜柿博物館設定為長期發展計劃，以帶動地方觀光產業，使優質產品行銷國際。
