✦ Synopsis

The effect of two dehydrated apple products (10 % in diet) -apple pulp (crude fibre 3.5 %, pectin i.4 %) and apple pomaces (crude fibre 13.5 %, pectin 7 %) -on the serum and liver lipids of growing Syrian male hamsters were studied. The animals were fed a natural diet (38 % of energy substituted by milk fat; the diet contains 53 mg ofcholesterol (CH)per 100 g) whichresultedin anaccumulation ofCH and triacylglycerols(TG)in theserumas well as in the liver, and CH-rich very low density lipoproteins (VLDL) in the circulation. After two months both apple products decreased the levels of CH and TG in serum (by 40-70 %) and the content of CH in VLDL with similar efficiency. Both products reduced CH content in the liver, and the apple pulp also decreased TGcontent. Up to the 6th month the apple pulp studied suppresses accumulation of CH and TG in both the serum and the liver. A complete analysis of lipoproteins ofmain density class at that time showed that the decrease of serum CH andTG toadecisive extentisduetothedecreaseoftheirconcentrationinVLDL(by more than 50 %).Therefore, the concentration ofVLDL and the whole lipoprotein pooldecreased by 50 %.The apple pulpdoubled theamount of CH transported by HDL. Three months after the replacement of butter in the diet by corn germ oil the CH and TG levels in the serum and TG also in the liver decreased to the physiological level. The apple pulp kept a higher level of the CH transport in HDL and decreased the CH content in the liver.
