Hughton, whose side beat Aston Villa 6-0 in their last home game, a first defeat in 27 games at St James' and the first since he became permanent manager proved a sobering experience.
He said: "Frustrating, very frustrating. We finished a game in perhaps not one of our better performances and created equally as many chances as we did against Aston Villa.
"But of course, we weren't able to put them away, and we came up against a very inspired goalkeeper today.
"It's a reminder of this division. We were on the back of our last home win and created the same amount of chances.
"But we had a very good day in front of goal that day. Today, we didn't and albeit that Blackpool are a team who came up with us, they have shown their quality."
