Abstract

Prve godine životu dojenčadi su od presudne važnosti za njegov/njezin psihofizički razvoj, a ključnu ulogu igra prehrana. Majčino mlijeko je najprirodnija hrana za dojenčad jer po svom kemijskom sastavu je najprilagođenija njihovim potrebama. Kada majka ne može dojiti onda se treba posegnuti za prehranom najsličnijom sastav majčinog mlijeka. U ovom radu je opisana uloga majčinog mlijeka u životu djeteta kao i uloga zamjene za majčino mlijeko. Posebno je naglasak stavljen na pripravu modificiranog kozjeg mlijeka uz dodatak masnih kiselina biljnog porijekla kako bi ono bilo što sličnije majčinom radi uporabe u dojenačkoj prehrani. Za potrebe ovog rada, provedena je priprava pet različitih mješavina biljnog ulja koje su dodane obranom kozjem mlijeku. Plinskom kromatografijom analiziran je sastav masnih kiselina i sterola u kozjem mlijeku, obranom kozjem mlijeku, biljnim mješavinama i modificiranom kozjem mlijeku. U modificiranom kozjem mlijeku u kojem je dodana mješavina biljnih ulja: kokosovo, šafranovo i ulje od soje u omjeru 2,5/1,1/0,8 (v/v/v) ima najsličniji sastav masnih kiselina kao i majčino mlijeko. Ukupni steroli kao i fitosterol u svim uzorcima pripravljenog modificiranog kozjeg mlijeka su slični koncentraciji u majčinom mlijeku, ali sadrži značajne količine stigmasterol, kampesterol i β-sitosterola.

Abstract (english)

First few years in life of an infant are of great importance from his/her psychophysical development, and key part of that is nutrition. Human milk is the most natural food for infants because it contains enough fats to give energy to infants. When the mother is unable to breastfeed than is necessary to reach out for food that is most similar in composition as human milk. In this work it is described the role of mothers milk in life of an infant and the role of substitutes for human milk an supplements for infant nutrition. Particular emphasis is put on caprine milk in which are added fatty acids of plant origin so it could be as similar as possible to human milk. For the purpose of this work, perparation of five diferent oils from plant origin was conducted, then those oils where added to skined caprine milk. Composition of fatty acids and sterols in caprine milk, skined caprine milk, mixtures of oil from plant origin and modified caprine milk was analyzed with gas chromatography. Modified capirne milk in which was added a mixture of oils from plant origin: coconut, safranic and soyabean oil in ratio 2,5/1/0,8 (v/v/v) has most similar composition of fatty acids as human milk. Total sterols and phytosterols content in each sample of prepared modified caprine milk is similar to content in human milk, but each sample of prepared modified caprine milk has significant conntent of stigmasterols, campesterols and β-sitosterols.
