2.1. Preparation of orange juice Oranges (Citrus sinensis L.) of the Navel variety (Spain) were purchased from a local supermarket. The orange juice was obtained, after suitable washing and hygienization of the fruits, by using a squeezer (FMC juice extractor with a 2-mm-diameter perforated plate), and it was then filtered with a 0.23-mm-pore-diameter filter. The juice was packaged aseptically and stored in refrigeration at 2 °C and 10 °C until analysis. 2.2. HIPEF treatment system Sample treatments were carried out in continuous HIPEF treatment system designed by the University of Ohio and located in the Instituto de Agroquı′mica y Tecnologı′a de Alimentos (CSIC) in Valencia. The system consisted of four treatment chambers with a diameter of 0.23 cm and an electrode gap of 0.293 cm connected in series and two cooling coils connected before and after each pair of chambers, immersed in a refrigerated bath in order to keep the temperature within the designated range (25°C). The flow was set at 60 ml/min and controlled by a flow pump (Cole-Parmer 75210-25, Cole-Parmer Instruments, IL). The temperature, wave form, voltage, and intensity in the treatment chambers were fed into a digital oscilloscope (Tektronix TDS 210, Tektronix, OR, USA). Treatment time was 100 ls and the electric field was set at 30 kV/cm. The temperature reached in the treatment chambers during treatment of orange juice does not exceed 49°C. These treatment conditions were selected on the basis of the results on carotenoid concentration, color, vitamin C, enzymes and microorganisms, obtained when the orange juice was treated using different fields (25, 30, 35, and 40 kV/cm) and different times (30–340 ls) .Samples were collected and packaged aseptically after HIPEF treatment and stored in refrigeration at 2°C and 10°C. |

2.1 橙汁的制备 脐橙（柑橘类、产地西班牙）购买于当地的超市。对脐橙进行适当的清洗和卫生化处理之后，对其使用榨汁机（FMC公司生产的具有2mm孔板的榨汁机）得到橙汁，然后把上述橙汁用0.23mm孔径的过滤器进行过滤。最终获得的橙汁经过无菌封装后冷藏于2 °C 和10 °C之间留待分析。 （FMC榨汁机 https://www.freepatentsonline.com/4700620.html） 2.2 脉冲电场处理系统 样品处理使用由俄亥俄州立大学设计的连续脉冲电场处理系统来完成，此系统位于巴伦西亚的西班牙国家研究委员会。这个系统包含四个直径0.23cm的处理室，四个处理室按电极间隙0.293cm互相串联，两个冷却线圈被安置在每对处理室的前后，同时冷却被浸入冷水浴以便让温度保持在设定的温度区间（25℃）。冷却水流量用水泵控制在60 ml/min（水泵为Cole-Parmer仪器公司的Cole-Parmer 75210-25型号）。处理室中的温度、波形、电压和强度都被输入到一个数字示波器（Tektronix TDS 210, Tektronix, OR, USA）中。处理时间为100 ls,电场强度为30 kV/cm。在橙汁处理过程中，处理室内的最高温度不要超过49°C。这些处理条件是基于类胡萝卜素浓度、色度、维生素C、酶和微生物的结果，通过用不同的电场强度（25, 30, 35, and 40 kV/cm）和不同的处理时间(30–340 ls)处理橙汁后得到的。在经过脉冲电场处理之后，样品被收集并重新无菌封装后冷藏于2 °C 和10 °C之间。  |
