Abstract

Zbog sve češćih pojava alergija na kravlje mlijeko i netolerancije na laktozu, te veće brige potrošača za zdravlje, okoliš i dobrobit životinja, suvremeni čovjek se okreće ka upotrebi biljnih napitaka i proizvoda na biljnoj bazi. U ovom radu je optimirana fermentacija kokosovog napitka uz dodatke s ciljem dobivanja fermentiranog kokosovog deserta. Praćen je tijek fermentacije i određivana su fizikalno – kemijska, senzorska i reološka svojstva dobivenih kokosovih deserata. Fermentiran je kokosov... More napitak (kontrola) te kokosov napitak uz dodatak brašna sjemenki rogača sa ili bez dodatka stevije ili saharoze. Vrijeme fermentacije kokosovog napitka iznosilo je 14 h. Fermentirani napitci promatrani su kroz period od 14 dana. Svim fermentiranim uzorcima pratio se udjel soli, mineralnih tvari i suhe tvari, te određivali kiselost, kapacitet zadržavanja vode, sinereza, reološki parametri te mikrobiološka i senzorska analiza. Senzorski najbolje ocjenjen napitak je fermentirani kokosov napitak s dodatkom brašna sjemenki rogača s 3 % saharoze. Less

Abstract (english)

Due to the increasing occurrence of allergies to cow's milk and lactose intolerance, and greater consumer concern for the health, environment and welfare of animals, modern man is turning to the use of plant-based drinks and products. In this paper, the fermentation of the coconut drink with additives is optimized with the aim of obtaining a fermented coconut dessert. The course of fermentation was monitored and the physico - chemical, sensory and rheological properties of the obtained coconut... More desserts were determined. Coconut drink (control) and coconut drink with the addition of carob seed flour with or without the addition of stevia or saccharose were fermented. The fermentation time of the coconut drink was 14 h. Fermented drinks were observed over a period of 14 days. The content of salt, minerals and dry matter were monitored in all fermented samples, and acidity, water separation capacity, syneresis, rheological parameters, and microbiological and sensory analysis were also determined. The sensory best rated drink is a fermented coconut drink with the addition of carob seed flour with 3 % saccharose. Less
