Dear applicant it's great that you have interest to finish your career goals from abroad. If you wish to pursue your higher study or post graduate in Food Technology you have to appear for exams like TOEFL, IELTS etc. But I have one suggestion, after completing Bachelor's in Civil Engineering the best way to pursue food technology is that you appear for GATE Examination and while applying you can ensure your M.Tech in Food Technology course, if you crack the exam successfully you have chances to fulfill your desire in a better manner.

Good luck!!
