Cricket powder (CP) contains significant amounts of protein, fat (including unsaturated fatty acids), and fiber, as well as vitamins and minerals. The high nutritional value and low price make it an interesting addition to food production. This paper is a report on the results of the addition of cricket powder to pasta. Three levels of durum semolina replacement were chosen: 5%, 10%, and 15%. The obtained products were analyzed for their nutritional composition, cooking and textural properties, and color, as well as consumer acceptance. The results indicate that the addition of CP influenced the cooking weight and cooking loss (reducing losses and water absorption), as well as the color of the pasta, reducing its lightness and shifting color balances to blue and red. The firmness of pasta was also influenced. The firmness was strengthened by addition of CP. Principal components analysis indicated that the flavor change had the most pronounced effect on consumer acceptance. Nevertheless, sensory evaluation proved that protein-enriched pasta produced with CP has consumer acceptance comparable with that of conventional products.

Sunflower is a pollinator-dependent crop and one of the most cultivated oilseeds in the world, supporting important sectors of the agricultural industry, such as the food supply, because it is an important source of vitamin E and unsaturated fatty acids for human health. Although it is well stablished that bee pollination improves sunflower seed set, it is still unknown if pollinators influence the nutritional composition. Considering the economic importance of sunflowers for several Brazilian agricultural sectors, the aim of this study was to evaluate the effect of the bee community for (1) achene quality (weight and nutritional composition) and (2) market value. Exclusion experiments were performed with hybrid sunflowers and showed that bee pollination enhanced the achene weight by 91 %, the levels of vitamin E by 45 % and unsaturated fatty acids by 0.3 %. Also, it was estimated that due to the pollination services provided by bees, the grower of the sunflower cultivar used in this study nearly duplicates the sale value of the achenes per hectare of cultivated area. Thus, the current study highlights the importance of bees as providers of cross- and self-pollination to nutritional quality of sunflower achenes and provides useful baseline figures to further evaluations of the effects of pollinators on human diets and health.

The work shows the influence of the electromagnetic field of the microwave range (EMF microwave) on the variability of fatty acids and their derivatives in seedlings of corn of different ages. The object of the study was the corn seeds of the Belarusian selection of the Daria hybrid, which were treated with microwave EMF for 12 minutes with a frequency of 64–66 GHz, exposure power 10 mW. The control was untreated EMF microwave seeds. Fatty acids were determined by gas chromatography with mass spectrometry (GC-MS). Analysis of fatty acids and their derivatives, occurring in seedlings of corn of different ages, showed that in the roots and leaves of corn fatty acid metabolism goes in different ways. On the 4th day of growth, the content of the following oxylipins increases in maize seedlings: hydroxymethyl ester of linoleic acid and octadecanoic acid, 2,3-dihydroxy propyl ether by 57.8% and 26.8%, respectively. By the 12th and 14th day of growth, the content of α-linolenic acid, which is the starting material for the synthesis of oxylipins, substantially increases in the roots of corn. Also, unsaturated fatty acids predominate in the roots, saturated in the leaves. Under the influence of the electromagnetic field of the microwave range in the roots of corn, a decrease in the content of saturated and, accordingly, the degree of unsaturation of fatty acids increases. In leaves, on the contrary, there was an increase in the amount of saturated and a decrease in unsaturated fatty acids after EMF treatment of corn seeds. Polyunsaturated fatty acids, linoleic and linolenic, predominate in the seedlings, roots and leaves of corn. In this regard, it can be assumed that the stimulating effect of pre-sowing treatment of microwave EMF on germination, growth and development of corn occurs through the accumulation of unsaturated fatty acids and oxylipins as a response of the plant to exogenous exposure.

The influence of the diet on larval growth of the scallops Argopecten nucleus was studied, testing six microalgae diets composed by single-algae and mixed diets of the species Isochrysis galbana, Chaetoceros calcitrans y Tetraselmis suecica, handling a concentration per mL equivalent to 40000 cells of I. galbana and the response through the variables surviving, growth, appearance of the eye spot and state of condition (full, half-full and empty larvae) was measured. The diets containing I. galbana showed greater results over all the measured variables, with regard to those where it was not present. In particular, the mixed diet I. galbana + C. calcitrans presented superiority over all variables, although in the most cases was statistically similar to I. galbana + C. calcitrans + T. suecica, I. galbana + T. suecica and I. galbana alone. For the opposite, the diets with the lowest results were C. calcitrans and C. calcitrans + T. suecica. The results obtained are principally attributed to the nutritional composition mainly of high unsaturated fatty acids (HUFA) of each microalgae and each mixture supply, which is discussed in detail.

The present study was aimed at analyzing the fatty acid composition, tocopherols, and physico-chemical characterization of wood apple (Limonia acidissima L.) seed oil and the nutritional profile of seed cake. The fatty acids in seed oil were analyzed by gas chromatography–mass spectrometry (GC-MS), and the total seed oil was 32.02 ± 0.08%, comprising oleic (21.56 ± 0.57%), alpha-linolenic (16.28 ± 0.29%), and linoleic acid (10.02 ± 0.43%), whereas saturated fatty acid content was 33.38 ± 0.60% including palmitic (17.68 ± 0.65%) and stearic acid (14.15 ± 0.27%). A greater amount of unsaturated fatty acids (52.37%) were noticed compared to saturated fatty acids (33.38%); hence the seed is highly suitable for nutritional and industrial applications. Gamma-tocopherol was present in a higher quantity (39.27 ± 0.07 mg/100 g) as compared to alpha (12.64 ± 0.01 mg/100 g) and delta (3.77 ± 0.00 mg/100 g) tocopherols, which are considered as natural antioxidants. The spectrophotometric technique was used for quantitative analysis of total phenolic content, and it revealed 135.42 ± 1.47 mg gallic acid equivalent /100 g DW in seed cake. All the results of the studied seed oil and cake showed a good source of natural functional ingredients for several health benefits.

The Impact

Cobia, Rachycentron canadum, is an important recreational marine fish of growing popularity in the aquaculture industry. Knowledge of the impact of environment on their fatty acids (FAs) utilization may contribute to the understanding their feeding in culture condition especially as cobia is been considered for low salinity culture. This study investigates the variations in the fatty acid contents of cobia from Dungun coast, Malaysia with respect to the changes in seasons and feeding intensity. Saturated fatty acids (FAs) comprised the majority of FAs in muscle, followed by monoenes, total poly-unsaturated fatty acids (PUFAs) (n-3) and then total PUFAs (n-6) with no seasonal variation in the quantity. A similar trend was observed in liver but total saturated FAs was significantly higher during the inter-monsoon while total monoenes significantly accumulate during monsoon. During low feeding intensity, there was a significant accumulation of PUFAs (n-6) in the muscle tissue (P < 0.05). Gut content analyses showed that cobia significantly increased the consumption of mollusks during the inter-monsoon (P < 0.05), although bony fishes dominated their diet throughout the year with no significant seasonal differences (P > 0.05). Our results suggest that cobia lipids are composed of a significant quantity of omega-3 and omega-6 FAs, which are considered to have important health benefits. While the environmental variability especially salinity fluctuations and prey abundance that accompany seasonal changes have a significant impact on the nutritional composition of cobia in Malaysian waters, their nutritional quality is maintained.
