水煮維生素C流失70% 醫:1烹調方式保留最多營養
The horn antenna has a distinctive design that is enlarged towards the end. Horn antennas typically feature a directional radiation pattern with a high antenna gain of 10-20 dBi, some antennas have a higher gain such as the standard horn antenna up to 25 dBi. Horn antennas feature a low VSWR and a wide impedance bandwidth.
Double Ridged Horn Antennas are very popular from 200 MHz frequency to higher frequencies up to 40GHz. We have recently extended the usage frequency of this antenna up to 60 GHz.
This antenna's operating frequency has recently been increased to 60 GHz. The research process for the product line is still ongoing but is planned to be completed this year. To receive the most recent price and technical information on the new product, please contact us for more information.
Double Ridged Horn Antennas are suitable for both transmitting and receiving purposes, with applications:
- - Antenna measurement
- - Communication systems
- - Satellite tracking systems
- - Radar Detection System
- - Surveillance System
- - Electromagnetic Compatibility Testing (EMC test)
Recommended Accessories
- - Antenna Tripod: easy and fast-changing position. 100% stable after installing.
- - SMA Cable: High-quality special SMA cable

很多人都以為水煮最健康,然而,高齡醫學內科醫師傅裕翔指出,水煮蔬菜會造成維生素C流失高達70%,且長期只吃水煮,可能導致健康油脂攝取不足,進而影響荷爾蒙平衡。他並分析6種烹調方式優缺點,其中以營養保留度來看,凍乾食物最佳,其次也可選擇舒肥、壓力鍋。
醫師傅裕翔在個人粉專發文表示,多數人都忽略了水煮造成營養流失的問題,甚至會讓人錯過重要的微量營養素。因此了解「怎麼煮」很重要,他並整理出6種烹調方式優缺點如下,以供民眾參考:
1、凍乾:目前能最大保留營養的新技術,大多應用在蔬果點心上。優點是低溫冷凍把食材脫水,研究指出,此技術能完整保留蛋白質、維生素B群與C,保留率超過95%;此外,無額外脂肪吸收,適合隨時補充營養。缺點則是口感較為乾脆,但也因如此,更適合當點心。
