Abstract:
      The?digestions?in?vitro?of?triglycerides?with?different?carbon?chain?length?of?fatty?acids?in?human?body?were?simulated?by?pH-stat?method.?From?the?perspective?of?the?particle?size?of?emulsion,?the?effect?of?different?carbon?chain?length?of?fatty?acids?on?the?rate?of?digestion?in?vitro?of?triglyceride?was?studied.?The?results?showed?that?after?emulsification,?the?average?particle?size?of?tricaprylin?(C8)?was?minimum;?with?the?increase?of?carbon?number?differences?between?the?other?triglycerides?and?C8,?the?particle?size?increased.?Tricaprylin?(C8)?had?the?highest?rate?of?digestion?in?the?process?of?the?overall?digestion;?with?the?increase?of?carbon?number?differences?between?the?other?triglycerides?and?C8,?the?rate?of?digestion?reduced.?A?negative?correlation?between?particle?size?of?chylomicron?and?digestion?rate?of?triglyceride?was?found.?The?rate?of?digestion?of?tricaprylin?(C8)?was?the?highest,?followed?by?laurin(C12),?triacetin(C2)?and?tristearin(C18).
