Uvoznici koji prepakiravaju sjeme obavezni su nakon pakiranja ispitati klijavost. Neprodane količine sjemena povlače se s tržišta na kraju sezone i plasiraju u iduće dvije do tri sezone bez kontrole klijavosti te se događa da sjeme u prodaji ima lošu klijavost ili uopće nije klijavo. Cilj istraživanja bio je ispitati klijavost sjemena 24 povrtne vrste na uzorcima partija sjemena skladištenih u klimatiziranom skladištu i na uzorcima istih partija koje je na tržištu dvije vegetacijske sezone te usporediti s ispitanom klijavosti nakon uvoza. Istraživanjem je utvrđeno da klijavost sjemena celera listaša (Apium graveolens var. secalinum L.), celera korjenaša (Apium graveolens L.), peršina listaša (Petroselium crispum ssp. crispum L.), poriluka (Allium porrum L.), boba (Vicia faba L.), paprike (Capsicum annuum L.) i špinata (Spinacia oleracea L.)pada neovisno o u...

(noni) has been the focus of many recent studies due to its potential effects on treatment and prevention of several diseases. However, there are few in vivo and in vitro studies concerning its composition and antioxidant capacity. The aim of the present study was to determine the total polyphenol content (TPC) and antioxidant capacity of a juice commercialized as noni juice, but containing grape, blueberry and noni fruits. Commercial noni juice was compared against its separate constituents of blueberry and grape juice. Folin-Ciocalteu and DPPH• methods were used to determine the concentration of total polyphenol content and antioxidant activity, respectively. Commercial noni juice presented higher values of TPC (91.90 mg of gallic acid/100 mL juice) and antioxidant activity (5.85 mmol/L) compared to its 5% diluted constituents. Concentrated blueberry juice presented higher TPC and antioxidant activity than the other juices analyzed. Considering that...

Analysis of nutritional quality of standard school meals served in 18 primary schools indicated high consumption of cereal products, meat, particularly meat products, pastry and sweets, and lacking of fruits, vegetables, fish and legumes. New menu was designed with the aim of improving nutritional quality of schools’ meals through a new recipes based on gastronomy heritage, dietary habits and National guidelines, but also education and testing of children's acceptance. Initial step of the project was to test new menu through Pilot program in six schools during two weeks. Process was accompanied by educational activities through originally designed leaflet about healthy diet, new meals and nutritional benefits, and was distributed among all students. Children's acceptance of Pilot menu of 10 meals was analyzed ...

Iznimne je hranjive i zdravstvene vrijednosti. Jedno serviranje kuhane sparoge odlican je izvor vitamina K, folne kiseline, vitamina C i vitamina A. Od minerala bogat je izvor selena, bakra i mangana. Sparoga je poznata po sastavu fitonutrijenata, karotenoida (capsanthin, caprorubin, zeaxanthin), steroidnih saponina i flavonoida (rutin). Pokazuje jacu antioksidativnu aktivnost od brokule zbog veceg udjela flavonoida. Zahvaljujuci snažnom antioksidativnom kapacitetu pomaže u prevenciji srcanožilnih bolesti smanjenjem nakupljanja homocisteina, prevenciji arterijske hipertenzije, dislipidemije i dr. Potencijalno djeluje na pospjesivanje izlucivanja žucne kiseline i uklanjanje suviska kolesterola.
