There are more than 200 full-time colleges in India that offer BTech Food Technology course, out of which around 78 colleges consider JEE Main exam scores for admission. JEE Main is one of most prominent and competitive national-level entrance exams for admission to various engineering programs at UG level.

You do have various college and exam options to consider and grab a seat for course at a decent college, given you are well prepared for exam and perform well.

The BTech in Food Technology entrance tests are usually moderately challenging. The level of difficulty varies on the basis of the particular exam you're appearing for, whether it is at the national/state/college level. You need to have a strong hold on the PCM subjects, general aptitude, and logical reasoning sections to get excellent marks. 
Further, the difficulty level also depends on previous year results, student feedback, and the number of student applications received. You just need to focus on putting your best foot forward and getting good marks to secure a seat at a good college.

Honestly, if you're thinking long-term, go where you'll actually get support and peace of mind. BBIT might give you a B.Tech degree, but placements aren't great and there is pressure - attendance issues, internal marks, etc.

Surendranath College is more good and gives you time to focus on other things like coding, competitive exams, or higher studies. If you're motivated, you can do really well even with a B.Sc. It depends on your mindset.
