Abstract
This study aims to utilize 3D printing technology to prepare functional chocolates with high content and viability of probiotics. Firstly, in order to protect probiotics (L. plantarum, lpl) avoiding inactive by melting chocolate syrup, we used raw starches as different amylose/amylopectin ratios (up to ∼30% amylose) for preparing novel porous carriers to encapsulate them. Then the formed pores of porous starches (HPPS1:0,3:1,1:1,1:3,0:1) were identified by SEM and BET, and their ability to encapsulate lpl were compared (with HPPS3:1 showing the best behavior) based on the survival rate and gastrointestinal simulation system. Then HPPS3:1-lpl capsule was applied in 3D printed chocolate, with optimization of adding levels for the shaping property. Probiotic cell viability, rheology, texture, and digestion simulation were also compared. The results showed that the surviving amount of probiotics (107 CFU/g) in HPPS3:1-lpl@choc (add 15% HPPS3:1-lpl to the chocolate) was much higher than that in lpl@choc (102 CFU/g, without microencapsulation protection) after in-vitro digestion test, among which HPPS3:1-lpl@choc15 had the best shaping property. This research provides a new alternative strategy for utilizing porous starch carrier to encapsulate probiotics for melting 3D printing of chocolate (or other similar food materials) as personalized design.
