Cheeses matured in skin sack is traditionally produced in several Mediterranean countries, which in Croatia has been retained in the territory of Dalmatian hinterland. The characteristic of this cheese is its piquant flavour and aroma, as a consequence of ripening in anaerobic conditions in lamb skin. This type of cheese has been recognized and has its customers in the wider area of the Croatia, and it is an interesting touristic product. The major constraint is that the production of this type of cheese in Croatia has been reduced to sporadic production in several families that preserve the tradition of their ancestors and the produced quantities are insufficient to meet customers needs. In 2009, Dalmatian hinterland had 11 registered producers of this type of cheese, while there are currently only 2. A production and economic analysis was performed of the remaining producers in order to determine the production performance. Both family farms produce cheese from sheep milk, while the first farm owns 300 sheep and the second 500. The selling price of cheese reaches HRK 150 per kilo, which ensures the achievement of cost-effectiveness of production. The producers point out that all the produced quantity is sold to known customers through on-farm sales and the demand exceeds the supply. Such a product would arise extreme interest among tourists, while the basic prerequisite for that is increase of the annual production of cheese by increase of the number of producers, as well as their clustering and protection of the product by one of the quality marks at the EU level.

By-products of fruit processing, such as grapes and aronia pomace, are rich in fibre and polyphenols, and their application in bakery products could significantly improve nutritional value, bioactive potential and shelf life of final product. This research aimed at optimising wholemeal biscuit formulation with grape and aronia pomaces as partial substitutes for cocoa powder, using the desirability function. Ten formulations with the mixture of cocoa powder, grape and aronia pomace powders in different ratios (0-100%) were tested. The physical properties (texture, colour, thickness, diameter, spread factor), the sensory acceptability of biscuits, and microbiological safety were investigated. The interaction of all three mixture components significantly affected the instrumentally measured redness a* and liking of texture. Biscuit diameter, yellowness b*, and liking of flavour were affected by the interaction of aronia and grape pomace. Biscuit height, spread ratio, hardness, flexibility, toughness, appearance, and odour were not significantly influenced by the mixture composition. The optimized mixture composition contained cocoa, grape pomace, and aronia pomace in the ratio 76.4 : 17.5 : 6.1 (respectively), with the desirability of 0.78. After confirmation, biscuits with that mixture were proven better than the control, that contained 100% cocoa, in terms of decreased hardness (-23%) and toughness (-19%), having the same sensory acceptability, and were microbiologically safe for 5 months. The findings of this study indicate that aronia and grape pomace could be used as partial substitutes for cocoa powder up to 24.3% in the production of wholemeal biscuits.

This study aimed at evaluating the effect of roasting conditions on some physicochemical and nutritional properties of cashew nut lipid fractions at different temperature (100–160ᵒC) and time (20–60 min). Raw and roasted cashew nuts were also analyzed for their composition in fatty acid by GC-FID. Physicochemical properties of the oil showed that the oil yield of roasted cashew nut oil (56.67-31.67%) was significantly higher compared to unroasted oil (47.43%). Also, cashew nut oil with mean values revealed that acid (12-0.86 mg KOH/g of oil); saponification value (138.10-169.06 mgKOH/g of oil), iodine value (55.50-36.19 mg of I/100g of oil); TBA(0.012-0.18mg); p-anisidine value (0.55-0.66); peroxide value (7.26-3.05 meq/kg) and free fatty acid (1.07-1.50 % oleic acid) which indicated that cashew nut oil is edible, non-drying and may not be suitable for soap making. Results of GC-FID analysis of the ethyl esters of saturated and unsaturated fatty acid of raw and roasted cashew nut showed that unsaturated fatty acids represented 60.57% for unroasted samples with roasted samples (79.67–83.67%) while saturated fatty acids recorded (16.11–37.65%). The fatty acid composition of the oils shows the presence of four main fatty acids: palmitic (9.25–29.50%); stearic (4.4–9.34%); oleic (34.75–65.60%); and linoleic (1.35–20.66%) with high oleic to linoleic ratio associated with high oil stability. The order of increase is oleic > linoleic > palmitic > stearic in all the samples irrespective of roasting conditions. The result showed that minor changes occur in the fatty acids composition as the roasting temperature and time increased. It was concluded that the heat treatment used does not significantly affect the fatty acid profile content of cashew nuts preserving its antioxidant activity along with other bioactive compounds contained therein.

The study examined the nutritional composition and sensory attributes of cookie. In this study, blends of commercial wheat (CWF), yellow maize flours (YMF) and African walnut protein isolate (AWPI) were optimized for cookie production. The cookies were studied in a completely randomized design and assessment of the proximate composition was conducted. The best cookie samples with high protein and fiber, low fat and highest rating in sensory attributes were selected for the determination of vitamins and mineral composition. The result revealed that the control cookie was highest in moisture, fat and carbohydrate but lower in protein, ash and fibre. Enriched cookie 36.69g CWF, 39.57g YMF, 23.74g AWPI and 42.86g CWF, 42.86g YMF, 14.29g AWPI were highest in protein and fibre, respectively while 55.56g CWF, 33.33g YMF, 11.11g AWPI was low in fat. Overall acceptability was highest in control cookie followed by enriched cookie 55.56g CWF, 33.33g YMF, 11.11g AWPI. The vitamin composition of the selected enriched samples show that sample 42.86g CWF, 42.86g YMF, 14.29g AWPI had the highest value of 2.53 mg/100 g in ascorbic acid; sample 55.56g CWF, 33.33g YMF, 11.11g AWPI scored the highest value of 0.14, 0.07 and 1.33 mg /100 g in thiamine, riboflavin and niacin respectively, while sample 36.69g CWF, 39.57g YMF, 23.74g AWPI scored highest in vitamin A (276.67 mg/100g). The cookie sample 36.69g CWF, 39.57g YMF, 23.74g AWPI shows the highest values of 130.00, 0.043, 9.77, 333.33 and 85.00 for calcium, manganese, iron, sodium and phosphorus, respectively. The study recommends the use of flour proportion in sample 55.56g CWF, 33.33g YMF, 11.11g AWPI as an improvement of the nutritional and sensory attributes of enriched cookie.

Convenient caffeine sources include energy drinks that are increasing in popularity among recreational and professional athletes, military personnel, young adults, and other consumers seeking ‘’energy boosters’’. Since energy drinks are a relatively concentrated source of caffeine, there is a risk of missing individually targeted caffeine intake or risk of inadvertently high intake with adverse effects. Therefore, the accuracy of declared caffeine content of energy drinks is highly important, especially from a consumer point. The purpose of this study was to determine caffeine content of 15 beverages available on the Croatian market and compare the analytical with the declared value. Caffeine was determined by high performance liquid chromatography technique with photodiode-array detection (HPLC-PDA). In 5 of total 15 products, a higher caffeine content was determined in average of 3.01 % than the one declared, resulting with increased intake of 4.75 mg caffeine/serving. In another 10 analysed products the content of caffeine was lower in average of 5.33 % (4.79 mg caffeine/serving) in compare to the one declared. Therefore, only with accurate information about the caffeine content in energy drinks may consumers and clinicians be assured of safe usage.

The aim of this work was to determine the effect of fat and protein oxidation on the colour and texture of Biceps femoris (BF) and Semimembranosus (SM) muscles of smoked dry-cured ham Dalmatinski pršut. Fat and protein oxidation was determined by spectrophotometer methods of which fat oxidation by 2-thiobarbituric acid reactive substances method (TBARS) and protein oxidation by 2,4-dinitrophenylhydrazine (DNPH) method. Colour parameters (L*a*b* values) and texture profile analysis (TPA test) were also analysed. There was no statistical significant difference (P>0.05) between BF and SM in fat and protein oxidation. SM is an external muscle and is more exposed to oxygen than internal muscle BF. As a result of that SM showed slightly higher TBARS values than BF. Slightly higher values of carbonyls in BF can be explained by the higher water content in this internal muscle and thus by the stronger proteolytic activity. BF had higher L*, a* and b* values than SM. Higher values of adhesive force, cohesiveness and stringiness and lower values of hardness, adhesiveness, gumminess, chewiness and fracture were found for BF than for SM.

Mikotoksini su proizvodi sekundarnog metabolizma toksikogenih plijesni koji predstavljaju vrlo česte onečišćivače hrane i hrane za životinje. Ciklopiazonična kiselina (CPA) je indol-tetraminska kiselina koju sintetiziraju različite plijesni iz rodova Penicillium (P. griseofulvum, P. camemberti, P. commune, P. dipodomyicola) i Aspergillus (A. flavus, A. oryzae, A. tamarii). CPA je prirodni kontaminant hrane biljnog (kukuruz, kikiriki, riža) i animalnog podrijetla, uključujući mlijeko, sir i suhomesnate proizvode. Česta zajednička pojavnost CPA i aflatoksina u hrani i hrani za životinje upućuje na moguće sinergističko djelovanje. Iako toksični učinci CPA nisu detaljno proučeni, kod pojedinih životinjskih vrsta dokazano je tremorgeno, neurokemijsko i imunosupresivno djelovanje. S obzirom da je CPA slabo istražen mikotoksin, nužna su daljnja istraživanja njegove toksičnosti, pojavnosti te sinergističkog učinka više različitih mikotoksina koji se mogu nalaziti u istoj namirnici.
霉菌毒素是有毒物质二次代谢的产物，是造成食品和生命食品污染的主要原因。环噻唑啉酸（CPA）是一种吲哚四脒酸，由青霉属（P. griseofulvum、P. camemberti、P. commune、P. dipodomyicola）和曲霉属（A. flavus、A. oryzae、A. tamarar）的多个菌门合成。CPA 是玉米、大米和动物源食品（包括牛奶、奶酪和干肉制品）的天然污染物。Česta zajednička pojavnost CPA i aflatoksina u hrani i hrani za životinje upućuje na moguće sinergističko djelovanje.由于 CPA 的详细作用机制，可以确定其具有震颤性、神经性和免疫抑制性。霉菌毒素是一种毒性极强的致癌物质，可对人体造成严重危害。

S obzirom da je CPA slabo istražen mikotoksin, nužna su daljnja istraživanja njegove toksičnosti, pojavnosti te sinergističkog učinka više različitih mikotoksina koji se mogu nalaziti u istoj namirnici.","PeriodicalId":151907,"journal":{"name":"Hrvatski časopis za prehrambenu tehnologiju, biotehnologiju i nutricionizam","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130548458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mikotoksini predstavljaju toksične tvari koje učestalo kontaminiraju hranu i hranu za životinje, uzrokujući štetne učinke na zdravlje ljudi i životinja te značajne ekonomske gubitke diljem svijeta. Ovaj rad daje pregled dosadašnjih istraživanja i spoznaja o metodama biološke detoksifikacije mikotoksina. Biološka detoksifikacija podrazumijeva primjenu mikroorganizama i njihovih enzima s ciljem razgradnje ili modifikacije strukture mikotoksina, a rezultira transformacijom izvornih spojeva i nastankom manje toksičnih produkata, odnosno dekontaminacijom mikotoksina. Međutim, dosadašnja istraživanja i dobivene spoznaje još uvijek nisu rezultirale primjenom u prehrambenoj i stočarskoj industriji odnosno odobravanjem njihove uporabe od strane zakonodavstva. Potrebna su daljnja istraživanja o mehanizmima biorazgradnje, sigurnosti mikroorganizama, odnosno utjecaju primjene bioloških metoda na nutritivna svojstva i nastale produkte degradacije, kako bi metode biološke detoksifikacije mikotoksina mogle biti učinkovito primjenjene u industriji.

A study of the chemical composition, the antioxidant capacity and the sensory characteristics of three Bulgarian wines (vintage 2015) from the native cultivars Misket Vrachanski (white), Pamid (red) and Gamza (red), grown in the region of Pleven, Central Northern Bulgaria was carried out. The results showed that the wine composition was mainly determined by the cultivar and its peculiarities. Misket Vrachanski white wine had the lowest rate of sugar-free extract, glycerol, total phenolic compounds and the highest acid content. From the red wine samples, Pamid had lower rates for the above parameters compared to Gamza. The experimental wines were analyzed for total content of esters, aldehydes and higher alcohols. A correlation was found between the rates of the studied volatile components in the wines and their aromatic sensory characteristics. At the wine tasting, Misket Vrachanski that contained the most of esters and aldehydes, was the best evaluated, followed by Gamza and Pamid. There was no correlation between the amount of total phenolic compounds in the experimental samples and their antioxidant capacity, which according to ABTS and MRAP methods increased in the order of Pamid < Misket Vrachanski < Gamza.

Kravlje mlijeko je nutritivno bogata namirnica koja je u ljudskoj prehrani prisutna nekoliko tisuća godina. U zadnjih se nekoliko godina pojavilo pitanje o opravdanosti mlijeka kao sastavnog dijela pravilne prehrane čovjeka te potencijalnim štetnim učincima mlijeka na ljudskozdravlje. Mlijeko je jeftin i lako dostupan izvor važnih nutrijenata i svakodnevno je zastupljeno u ljudskoj prehrani te mu mnoge nacionalne prehrambene smjernice pridaju veliku važnost. Zato je važno poznavati njegov sastav te potencijalan pozitivan ili negativan utjecaj na ljudskozdravlje, kako djece tako i odraslih. Stoga je glavni cilj ovoga rada bio dati pregled najnovijih istraživanja o utjecaju mlijeka na rast djece, pretilost, rizik od osteoporoze i kroničnih bolesti, laktoza intolerancija te alergija na proteine mlijeka.
