Migration of nonylphenol and plasticizers from polyvinyl chloride stretch film into food simulants, rapeseed oil, and foods

Nonylphenol (NP) more easily migrated from polyvinyl chloride (PVC) stretch film into aqueous foods than diisononyl adipate (DINA) and di-n-alkyl adipate (DAA). The migration ratio of NP, DINA, and DAA into fatty foods, such as minced tuna and pork, came to 15%–37% of their contents in PVC films at 5°C for 24 hr. The estimated daily intakes of NP and DINA for Japanese individuals around the year 2000 were 35 and 1,050 µg, respectively, and should be no safety concern.

Physicochemical, functional, and nutritional characteristics of stabilized rice bran form tarom cultivar

Indeed, many works have been accomplished on the stabilization of rice bran and the effect of extrusion on some functional properties of food has been studied, but there is still lack of knowledge concerning the evaluation of stabilized rice bran and surveying of its functional and nutritional properties. Therefore, the main aim of the current work is to compare the functional, nutritional and biophysical characteristics of rice bran before and after stabilization. Certainly, these evaluations can be vital to utilize rice bran as a food ingredient for the human diet. From a commercial perspective, when there is a growing market for rice bran with added value and more scientific information available about its benefits, industries are expected to show more interest in processing the product for human consumption besides its current use as animal feed.

Evidence for decreased interaction and improved carotenoid bioavailability by sequential delivery of a supplement

Evidence for decreased interaction and improved carotenoid bioavailability by sequential delivery of a supplement

A randomized, double-blind, repeated-measure, cross-over study in adult humans evaluated the change of carotenoid levels in the plasma fraction for 8 hr after oral doses of a sequentially spaced carotenoid mix, in comparison to a nearly identical mix without sequential spacing. The carotenoid change from baseline, measured as area under the curve, is increased following consumption of the sequentially spaced mix over the change from baseline when carotenoids are delivered concomitantly. Spearman's correlation analysis also demonstrates less interaction and regulation between the sequentially spaced carotenoids, suggesting improved bioavailability from a novel sequential release mixed carotenoid formulation.

Effect of soy flour on nutritional, physicochemical, and sensory characteristics of gluten-free bread

In this study, corn flour was replaced with soy flour at different levels 5%, 10% and 15% to producing a more nutritionally balanced GF bread.The results of evaluations showed that protein, fat, fiber, and ash contents of soy flour-supplemented GF bread increased with the incremental addition of soybean flour. The highest total score of sensory evaluation was for the bread sample containing 15% soybean flour. Adding higher levels of soybean flour into GF bread can improve bread quality, sensory characteristics and nutritional properties of bread.

Anti-inflammatory and anti-insulin resistance activities of aqueous extract from Anoectochilus burmannicus

Anoectochilus burmannicus aqueous extract (ABE) showed anti-inflammatory activity by decreasing the level of inflammatory molecules including nitric oxide (NO), inducible nitric oxide synthase (iNOS), interleukin 6 (IL-6), IL-1β, and cyclooxygenase 2 (COX-2) in the LPS-treated RAW 264.7. Moreover, ABE exerted anti-insulin resistance activity as it significantly improved the glucose uptake in tumor necrosis factor (TNF)-α-treated 3T3-L1 adipocytes. The results of our study suggested the potential use of A. burmannicus as anti-inflammatory, anti-insulin resistance agents, or food supplement for prevention of chronic diseases.

Heat penetration attributes of milkfish (Chanos chanos) thermal processed in flexible pouches: a comparative study between steam application and water immersion

The difference in the heating penetration characteristics of product processed in retort by steam–air application and water immersion was studied. Fresh milkfish packed in dry pack and in oil medium, both in flexible pouches, was thermal processed to minimum F0 value of 7.77 at 121.1°C. Heat penetration data were recorded for every minute of processing using Ellab (TM 9608, Denmark) temperature recorder. Retort come up time to achieve 121.1°C was less in steam–air which led to a lower Ball's process time (B) and the total process time (T) observed in steam–air as compared to water immersion.

The residual water content is the most important factor which significantly influences the average yield of the essential oil and the content of the major constituents. Regarding the aerial part, a low residual water content of the plant material increases the essential oil yield and the content of cis and trans-p-mentha-2.8-dien-1-ol. To the roots, the samples which have a very low residual water content should provide extracts richer in aristolone.

This work investigated the spray drying conditions and novel formulations with mixtures of maltodextrin with small amounts of γ-cyclodextrin. The results of spray drying fruit juice with a combination of γ-cyclodextrins and maltodextrins show how these parameters affect the physical properties such as powder color, water-holding capacity, and astringency index. The pH appears to affect the color of the powders. The drying temperature interacts with the γ-cyclodextrin/maltodextrin formulation.

Nutritional advantages of sous-vide cooking compared to boiling on cereals and legumes: Determination of ashes and metals content in ready-to-eat products

In order to guarantee the highest quality of ready-to-eat cereals and legumes, two different cooking methods have been applied: traditional cooking and sous-vide. Ashes and metals content (magnesium, potassium, iron, zinc, and copper) has been determined and compared in 50 samples of red lentils, peas, Borlotti beans, pearl barley, and cereals soup. All the samples cooked with sous-vide showed a significant increase in the content of minerals with the exception of potassium in cereal soup, iron in Borlotti beans, and magnesium in pearl barley. Ash content increased in legumes and in cereal soup cooked with sous-vide method. The higher different ashes concentration between total samples cooked with traditional cooking and with sous-vide was registered in zinc (+862 mg), iron (+314 mg), potassium (+109 mg), and copper (+95 mg). Sous-vide is preferred as it provides products with a higher concentration of metals compared to the ones cooked with traditional cooking.
