Abstract
Plodovi borovnice (Vaccinium corymbosum L.) voće su visoke nutritivne vrijednosti. Proizvodnja ovog voća u svijetu napreduje, a količine plodova koji se stavljaju na tržište značajno rastu. Plodove borovnice je najbolje konzumirati svježe, ali mogu se konzumirati i u prerađenom obliku. Prerada borovnica u džem jedan je od načina prerade. Preradom borovnica u džem ne gube se antioksidativna svojstva ploda. Kvalitativna svojstva džemova namijenjenih tržištu propisana su na nivou Europske unije. Šećer, pektin i kiselina u uzajamnom djelovanju određuju konzistenciju džema, ali i druge kvalitativne karakteristike. U ovom radu istražuje se utjecaj različitih pektina u kombinaciji s različitim količinama dodanog šećera na osnovne karakteristike džemova. Borovnice prirodno sadrže dovoljno pektina da uz dovoljno dodanog šećera formiraju gel. Dodavanjem određenih pektinskih preparata moguće utjecati na konzistenciju džema, skratiti vrijeme pripreme, smanjiti udio dodanog šećera te povećati količinu gotovog proizvoda.
Abstract (english)
Blueberry fruits (Vaccinium corymbosum L.) are fruits of high nutritional value. The production of this fruit in the world is thriving, and the quantities of blueberries placed on the market are growing significantly. Blueberries are best consumed fresh but are also available for consumption in processed form. Processing blueberries into jam is one of the methods of processing. The qualitative properties of jams intended for the market are regulated at the level of the European Union. Sugar, pectin and acid in mutual interaction determine the consistency of jam, but also other qualitative characteristics. This paper investigates how different pectin in combination with different amounts of added sugar influence the basic characteristics of jams. Blueberries naturally contain enough pectin to form a gel with enough added sugar. By adding certain pectin preparations, it is possible to affect the consistency of jam, shorten the preparation time, reduce the content of sugar added and increase the quantity of the finished product.
