หูฉลาม...คุณค่ายิ่งใหญ่เท่าไข่ฟองเดียว
By Joeadmin @ 9:53 AM :: 4810 Views :: Article Rating :: วิทยาศาสตร์รอบตัว(จาก สสวท.)
 

      หูฉลามเป็นอาหารขึ้นโต๊ะที่ราคาแพงมาก เหตุผลก็เพราะหายาก มีรสชาติดี จึงถือเป็นอาหารชั้นเลิศของชาวจีนแต่ครั้งโบราณกาล  ในเรื่องความอร่อยและความหายากนั้นคงไม่ขัดใจกัน ถ้าหากพูดคุยกันรู้เรื่องกับนักอนุรักษ์ธรรมชาติ แต่ในแง่คุณค่าทางอาหารว่ามีสรรพคุณล้นหลามตามคำเชิญชวนนั้น น่าจะลองคำนวณดูว่ามีคุณค่าสมราคาหรือไม่

      แท้จริงแล้วหูฉลามมาจากส่วนครีบของปลาฉลาม ซึ่งมีลักษณะเป็นกระดูกอ่อนที่แบ่งออกได้เป็นสองส่วน คือฐานครีบและก้านครีบ  ซึ่งเป็นกระดูกที่มีลักษณะเป็นเส้นๆ เพื่อช่วยให้ฉลามสามารถแผ่ครีบออกได้  ส่วนที่เรียกว่าก้านครีบนี่แหละครับที่กลายเป็นหูฉลามชามโปรด

      มีความเชื่อกันว่าหูฉลามที่นำมาต้มจนเปื่อยและตุ๋นจนได้ที่จะกลายเป็นอาหารวิเศษในการบำรุงร่างกาย แต่ข้อสังเกตในทางวิทยาศาสตร์ก็คือ ครีบฉลามที่นำมารับประทานนี้ ได้ผ่านกระบวนการหลายอย่าง ตั้งแต่การแตกแห้ง ต้มจนเปื่อย และขูดหนังทิ้งจนเหลือแต่กระดูกอ่อน เหลือแคมเซียมอยู่ก็ไม่กี่มากน้อย

     สิริรวมในเรื่องคุณค่าด้านอาหารแล้ว หูฉลามหนึ่งชามมีค่าเสมอด้วยไข่เป็ดฟองเดียวเท่านั้นเอง

     การเลือกซื้ออาหารเพื่อคุณค่าสูงสุด จึงไม่ได้หมายถึงอาหารราคาแพงเท่านั้น ถ้ามีความรู้และรู้เท่าทันด้วย การใช้เหตุผลทางวิทยาศาสตร์ มักจะได้ทั้งของถูกและของดีพร้อมกันในคราวเดียว
