百香果目前的取漿方式有採用人工剖開果實後再挖取其中的果漿方式，以及利用機器輾壓破裂果實再分離果皮與果漿兩種方式進行。為了增快取漿效率，通常會採用機器作業方式來榨取百香果果漿。然而機器輾壓破裂鮮果的方式，經常導致果漿與果皮滲出的組織液與果皮上殘餘的藥劑混雜，造成果漿品質的劣化，並且會產生食品安全上的虞慮。因此，為了維持後端加工產品的品質與風味，通常還是會採用人工方式進行取漿。然而，人工取漿方法需耗費大量人力與時間，且人工作業效能太低，常常無法及時進行百香果的處理而造成產業的損失。為解決百香果產業所面臨的發展困境，農業試驗所便進行省工自動化百香果果漿抽取設備之開發研究以提供產業利用。本研究利用開孔機構先進行果殼的開孔，再應用吸漿探管進行果實內部進行果漿之抽取，此種作業方式可以完全避免果漿遭受果殼組織液或果皮表面的藥劑汙染，可維持果漿之品質、衛生與安全。本機各部機構作用利用可程式化控制系統進行調控，核心技術之果漿抽吸作業機構可以依產業需求調整抽吸作業次數，依據試驗結果顯示，進行1次抽吸作業的百香果平均取漿率可達93.3%，2次抽吸作業的百香果平均取漿率則可達97.8%，本技術已經以「百香果漿抽取設備與方法」名稱遞案智慧財產局申請發明與新型專利審核中，並著手辦理後續技術移轉作業以提供百香果產業利用。

At present, there are two ways to pulp the passion fruit. One is to cut open manually to scoop the pulp, the other is to crush the fruits then separates the skin from the pulp. In order to increase the pulping efficiency, the crusher is adopted. However, the crusher will result in the exuded tissue fluid mixing the residual chemicals on the peel causing the quality deterioration of the passion fruit pulp. Therefore, manual pulping is used to ensure the quality of the rear end processing products. However, low efficiency manual pulping takes a lot of labor work and time and usually cannot process the pulps in time resulting in industrial loss. To resolve the dilemma of the passion fruits industry, TARI conducts research and development on labor saving automatic pulping facility. The facility adopts a mechanism to bore a hole on the peel. A suction tube is then inserted and extract pulp out of the fruit. This operation avoids the pulp from contaminating with (of) chemicals or exuded tissue fluid and maintain the quality, hygiene and safety of the passion fruit pulp. The operations of the mechanisms of the facility is controlled by PLC. The core technology of the pulp extraction operations can be adjusted according to the industrial demand. According to the testing results, the average one time pulping rate is 93.3% and 2-time pulping rate is 97.8%, respectively. The technology has been named ＂Passion fruit pulp extraction facility and method＂ for invention and new-type patent application to the Intellectual Property Office. The follow-up technology transfer operations is also processed to benefit the passion fruit industry.
