By Products

Acid oils (AO) and fatty acid distillates (FAD) are oil refining by-products rich in free fatty acids. The objective of this study is their characterization and the identification of their sources of variability so that they can be standardized to improve their use as feed ingredients. Samples (n=92) were collected from the Spanish market and the MIU value (sum of moisture, insoluble impurities, and unsaponifiable matter), lipid classes, fatty acid composition, and tocol content were analyzed. Their composition was highly variable even between batches from the same producer. As FAD originated from a distillation step, they showed higher free fatty acid amounts (82.5 vs 57.0 g/100 g, median values), whereas AO maintained higher proportions of moisture, polymers, tri-, di-, and monoacylglycerols. Overall, the MIU value was higher in AO (2.60–18.50 g/100 g in AO vs 0.63-10.44 g/100 g in FAD), with most of the contents of insoluble impurities being higher than those in the guidelines. Tocol and fatty acid composition were influenced by the crude oil’s botanical origin. The calculated dietary energy values were, in general, higher for AO and decreased when a MIU correction factor was applied. The analytical control and standardization of these by-products is of the outmost importance to revalorize them as feed ingredients.

Nutritional Characteristics

O consumo brasileiro de sardinhas em conserva coloca este alimento como importante fonte de ácidos graxos da série w-3, de alto valor nutricional. Como, em geral, nos produtos conservados em óleo comestível, o óleo de cobertura é parcialmente descartado, quando da ingestão do pescado, verificouse a influência do armazenamento, em condições ambientais, na migração destes ácidos para o óleo de cobertura. Observou-se que as condições de processamento provocam migração dos ácidos característicos da sardinha para o óleo de cobertura. A partir deste ponto, apenas pequena variação ocorre na composição em ácidos graxos do óleo de cobertura do produto, durante 180 dias de armazenamento. Esta variação não compromete a relação w-3/w-6 apresentada pela sardinha drenada e, portanto, não prejudica o valor nutricional do produto. Abstract Brazilian consumption of canned sardines places this product as an important source of w-3 fatty acids, of high nutritional value. As, in general, in products conserved in eatable oil, the covering oil is partially discarded previously to the sardine ingestion, it was verified the influence that the storage at room temperature could have on the migration of ­3 fatty acids from the sardine lipids to the covering oil. It was observed that the processing conditions provoke migration of the characteristic acids of the sardine for the covering oil. The analyses were performed 30 and 180 days after processing. However, from there on, the changes in the fatty acid composition of covering oil are smaller and it was concluded that under the storing conditions the nutritional characteristics of the product are not affected, and the ratio w-3/w-6 isn’t committed.

Marine Copepod

The marine copepod species Oithona nana is considered as one of the most successfully mass cultured Cyclopoida species in marine hatcheries. This study investigated the effects of four feed diets (soybean, yeast, rice bran, and corn starch) on the population growth, growth rate, population composition, fecundity, and fatty acid composition of native isolated Cyclopoida copepod species O. nana. The experiment was continued for 15 days and the copepods were fed on one of the four diets with a concentration of 1 g 10−6 individual day−1. The results revealed that corn starch was found to be the most supportive diet for population growth and population growth rate. For nutritional value, copepods fed on rice bran were detected to have the highest content of MUFA, PUFA, and the lowest SFA and SFA/UFA ratio; more importantly, the rice bran diet was the only treatment that showed C20:5ω3. Moreover, copepods fed on rice bran showed the highest significant female fecundity, copepodite, and nauplii percent. Finally, the protocols described in the current study concluded that the dry feeds, especially corn starch, are very useful and applicable in hatcheries for maximizing the fecundity and density of Cyclopoida copepod species, O. nana.

Intensive Production

Dairy sheep farming is a vital sector of the agricultural economy in Greece. Information on the effect of the farming system on sheep milk characteristics is critical for producing dairy products with improved nutritional value according to the current guidelines for healthy food consumption. This study aimed to investigate the basic composition, physicochemical characteristics, fatty acid composition, and nutritional indices of milk produced in intensive and semi-intensive sheep farms. Bulk tank milk samples from 20 intensive and 20 semi-intensive sheep farms were examined. Sheep in the intensive farms were kept indoors and were fed with roughage, silage, and concentrates. Sheep in the semi-intensive farms were kept indoors during the night and were moved to the pastures during the day. Sheep were fed with roughage, silage, and concentrates in combination with grazing. Milk composition and somatic cell count were determined with automatic analyzers. The physicochemical characteristics were determined with standard laboratory methods. The fatty acid composition was analyzed by gas chromatography. The farming system did not affect milk chemical composition and physicochemical characteristics. However, milk fatty acid composition and nutritional value were significantly improved in milk from farms using the semi-intensive production system, and this favorable effect was attributed to the inclusion of pasture in sheep diet.
