Effects of adding solid and molten chocolate on the physicochemical, antioxidant, microbiological, and sensory properties of ewe's milk cheese.
2020
Abstract: A novel dairy product, namely “chocolate cheese”, was produced with two typical Sicilian food products: Pecorino cheese, processed from ewe's milk, and Modica chocolate. The cheese, manufactured with 0%, 5%, 10%, and 15% (w/w) solid or molten chocolate, was evaluated after 0, 2, 4, and 6 weeks of vacuum storage for its nutritional and health properties. The addition of chocolate reduced the pH, protein, fat, and ash; the addition of 5% or 10% molten chocolate reduced hardness (N/mm2). The addition of either solid or molten chocolate resulted in a slight increase (P < 0.1038) in the total polyphenol content, a higher oleic acid content, and less oxidative stability. The microbio…
Effect of muscle type and animal category on fatty acid composition of bresaola made from meat of Cinisara cattle: preliminary investigation
2020
The bresaola could represent an alternative commercial opportunity for autochthonous dairy cattle farms. Therefore, a study was carried out to investigate the fatty acid (FA) composition of bresaola made using Semimembranosus (SMm), Semitendinosus (STm), and Biceps brachii (BBm) muscles from grazing young bulls (GB), housed young bulls (HB) or grazing adult cows (AC) of Cinisara breed. Animal category, fat content, feeding system, and type of muscle influenced the FA composition of bresaola. Fatter products, made from AC and HB meat, or with STm and BBm muscles showed lower polyunsaturated/saturated FA ratio. The bresaola from young bulls fed pasture-based diet showed an increased polyunsat…
Effect of farming system and cheesemaking technology on the physicochemical characteristics, fatty acid profile, and sensory properties of Caciocaval…
2012
Abstract Caciocavallo Palermitano is a typical stretched-curd cheese that has been produced over the centuries in Sicily according to traditional cheesemaking technology and using raw milk from autochthonous cow breeds reared at pasture. The objective of this experiment was to evaluate the effects of the farming system and processing technology on the characteristics of Caciocavallo Palermitano cheese, with particular regard to the fatty acid profile. The farming system was either extensive, using autochthonous cows fed a pasture-based diet, or intensive, with specialized dairy cow breeds fed mainly hay and concentrate. The cheese-processing technology was either artisanal, using traditiona…
Persistent Organic Pollutants and Fatty Acid Profile in a Typical Cheese from Extensive Farms: First Assessment of Human Exposure by Dietary Intake
2022
Dairy products represent an important source of beneficial substances for humans. At the same time, they can expose the consumers to environmental contaminants ingested by animals through their diet, influencing their health negatively. This experiment aims to evaluate the risk and benefits related to the consumption of typical stretched cheeses, considering their fatty acid (FA) profile and persistent organic pollutants (POPs) content. Six representative farms, two of them organic, raising Cinisara cattle were selected, considering the typical extensive management systems, based on feeding of natural pasture integrated with concentrate and hay depending on the availability of forage on pas…
Interaction between stearoyl-coenzyme A desaturase polymorphism and feeding system in affecting the fatty acid profile of sheep cheese
2021
Stearoyl-coenzyme A desaturase (SCD) catalyses the synthesis of monounsaturated fatty acids, by introducing a cis double bond at the delta 9–10 position. The study investigated the effects of a polymorphism at the ovine SCD gene and its interaction with the inclusion of fresh forage in the diet on cheese fatty acid (FA) composition in Valle del Belice ewes. A region of 527 bp of the ovine SCD gene including the partial sequence of the promoter, the complete sequence of the 5’ UTR and exon 1 and the partial sequence of intron 1 were analyzed in order to identify the g.87C > A SNP located in the promoter region. A feeding trial was carried out using 16 Valle del Belice ewes selected on the…
Evolution of indigenous starter microorganisms and physicochemical parameters in spontaneously fermented beef, horse, wild boar and pork salamis prod…
2020
Abstract The present work was carried out to evaluate the microbiological and physicochemical composition of salamis produced with the meat of beef, horse, wild boar and pork. Salami productions occurred under controlled laboratory conditions to exclude butchery environmental contaminations, without the addition of nitrate and nitrite. All trials were monitored during the ripening (13 °C and 90% relative humidity) extended until 45 d. The evolution of physicochemical parameters showed that beef and pork salamis were characterized by a higher content of branched chain fatty acids (FA) and rumenic acid than horse and wild boar salamis, whereas the last two productions showed higher values of …
Effects of Grazing on the Behaviour, Oxidative and Immune Status, and Production of Organic Dairy Cows
2019
This study compared the effects of a short daily grazing time with those of permanent free-stall housing on the behaviour, oxidative status, immune response, and milk production of organically reared cows. During a 63-day period, two homogeneous groups of eight lactating Brown cows were allocated to either housing (H) in a free-stall building for 24 h/day. Feeding was based on a total mixed ration or grazing (G) on barley grass for 5 h/day, and housing in a free-stall structure with feeding was based on the same total mixed ration offered to the H group. With regard to behaviour, H cows spent more time idling, walking, drinking, and self-grooming, whereas G cows showed a greater intent to e…
The production of typical cured meats from cattle of Cinisara breed
2019
In recent years consumers prefer genuine, tasty, protein-rich, low in fat and cholesterol products. The Cinisara cow is a dairy Sicilian autochthonous breed, reared in the western part of the isle according to the traditional livestock system, based on grazing natural pastures. The meat of Cinisara cattle could be used to obtain also processed products, among which salami and bresaola, as commercial alternatives to fresh meat, in order to increase the economic profitability of farms. The aim of this research was to produce bresaola and salami with meat from adult cows (AC) and grazing (GB) or housed (HB) young bulls of Cinisara breed, evaluating their physico-chemical and sensory traits. In…
ORGANIC SHEEP MILK PRODUCTION AND QUALITY BY USE OF LEGUME GRAINS AS DIETARY SUPPLEMENT
2013
The aim of this study was to evaluate the sheep milk yield and quality as affecting by concentrate dietary supplements prepared on farm by mixing locally produced barley and legume grains, used as alternative to a commercial feed. A total of twelve milking ewes, averaging 92±9 days in milking and 56±6 kg of live weight, were housed in individual pens and divided homogeneously into four groups. Each group was fed ad libitum with a grass-legume hay and received, according to a 4x4 Latin square design with periods comprised of 21 days, one of the following isonitrogenous concentrates: 500 g chickpea and 300 g barley (CP); 450 g faba bean and 350 g barley (FB); 550 g pea and 250 g barley (PE); …
Transfer of milk fatty acids to Pecorino Siciliano cheese
2011
In previous studies it was observed that milk fatty acid (FA) composition is mainly affected by diet, and when ruminants graze pasture the percentages of polyunsaturated FA and conjugated linolenic acid (CLA) are higher than in milk from preserved forage. The maintenance in the cheese of the beneficial FA profile of milk from grazing ruminants is advisable. Little number of study exists concerning the effect of milk processing conditions on cheese FA profile, but no study was done with regard to Pecorino Siciliano cheese. The aim of this study was to evaluate the transfer of FA from ewes milk to cheese manufactured according to the Pecorino Siciliano technology, in order to verify if the ch…
