“…Similarly, another significant statistical positive correlation was also found between dialyzable Fe (mg/kg) and dialyzable Cu (mg/kg; p < 0.05; r = 0.452). This synergistic effect between both elements has also been reported in other in vitro studies with a food matrix such as legumes (lentils and chickpeas) (Ramírez-Ojeda et al, 2018), weaning foods (Ramírez-Ojeda et al, 2017), hospital meals (Velasco-Reynold et al, 2008), and school menus (Cámara, Barberá, Amaro, & Farré, 2007). The mechanism for this positive interaction remains unclear; however, this strong correlation between both elements has just been reported for in vivo models.…”

“…Although several studies have already documented a positive effect of animal protein upon Fe bioaccessibility (Ramírez-Ojeda, Moreno-Rojas, Sevillano-Morales, & Cámara-Martos, 2017;Storcksdieck, Bonsmann, & Hurrell, 2007), the effect with other protein sources is less clear (such as vegetable proteins). There are some studies reporting a negative effect (Berner & Miller, 1985) while other authors have also shown this positive effect on Fe bioaccessibility (Joshi, Thatte, Prakash, & Jyothi, 2014;Lombardi-Boccia, Carbonaro, Di Lullo, & Carnovale, 1994,).…”

Background and objectives: Fe, Zn, Cu, and Mn contents as well as bioaccessible fractions of eight rice varieties were analyzed in order to evaluate them nutritionally. Findings: Total trace element concentrations ranged between 5.90 and 15.3 mg/ kg for Fe, 8.82-12.9 mg/kg for Zn, 1.45-5.59 mg/kg for Cu, and 2.45-13.6 mg/ kg for Mn. Brown rice presented the highest trace element contents and at the same time the lowest bioaccessibility. A negative significant statistical correlation was found between dietary fiber and Mn bioaccessibility (r = −0.872; p < 0.01).Significant statistical negative correlations were found between vegetable proteins of rice and trace elements bioaccessibility. Conclusions: A probabilistic assessment (@Risk) used to determine the contribution of DRI for Fe, Zn, Mn, and Cu through the intake of 150-200 g of boiled rice showed that this food can be a proper source of Cu and to a lesser extent Mn but not in the case of Fe and Zn. Significance and novelty: The present study develops a probabilistic model to evaluate the contributions to the DRIs of these micronutrients, from data of rice varieties consumption and their bioaccessibility-total content.

“…Thus, bioavailability studies can be partly replaced by bioaccessibility ones. This term refers to the fraction of the micronutrient or bioactive compound that is soluble in the intestinal lumen and therefore will be capable of being absorbed by the enterocytes of the small intestine [20]. Bioaccessibility studies are based on a simulated gastrointestinal food digestion formed by an oral phase with salivary amylase, a gastric phase with pepsin-HCl at pH 2, and later by an intestinal phase with pancreatin-bile salts [21,22].…”

Brassica Breeding and Biotechnology

Brassica rapa includes oil and vegetable crops having a variety of forms, such as oilseeds, leafy vegetables and turnips. Leafy types, which are called turnip greens and turnip tops, are popular crops in NW Spain, and they represent an important part of the diet. However, their cultivation is limited in southern areas or in the Mediterranean basin, probably due to a lack of adaptation. Still, they could occupy a prominent place in the Mediterranean diet, which is based on a high consumption of fruits and vegetables. In this review, we summarize the studies on the agronomical and nutritional value of these crops when grown under Mediterranean climate conditions. Data reported here might be useful for a deeper understanding of these crops for both nutritional quality and bioaccessibility, and for selecting varieties adapted to the two abovementioned Mediterranean conditions, as well as for organic farming systems, thus contributing to the diversification of traditional Brassica vegetable production systems.

“…In this context, during the development of a new compound feed for animals, it is not only important to consider the nutritional guidelines and the legal limits, but also to assess the bioaccessibility and bioavailability of elements like Zn, because their source and the composition of the matrix influences both factors [7][8][9][10][11][12]. Zinc can be present in dog food as free or inorganic zinc, and also complexed with amino acids (e.g., histidine, methionine, glutamate, and glycine) or with other low-molecular-weight organic molecules (e.g., citrate, ascorbate, picolinate, and propionate) [2].…”

Flow-Based Dynamic Approach to Assess Bioaccessible Zinc in Dry Dog Food Samples

This work proposes a simple and easy-to-use flow-through system for the implementation of dynamic extractions, aiming at the evaluation of bioaccessible zinc and the characterization of leaching kinetics in dry dog food samples. The kinetic profile of Zn extraction was determined by flame atomic absorption spectroscopy and the results were fitted in an exponential function (R2 > 0.960) compatible with a two first-order reactions model. Values of fast leachable Zn ranged from 83 ± 1 to 313 ± 5 mg of Zn per kg of sample, with associated rate constants ranging from 0.162 ± 0.004 to 0.290 ± 0.014 min−1. Similar results were observed compared to the static batch extraction. The percentage of bioaccessible Zn ranged from 49.0 to 70.0%, with an average value of 58.2% in relation to total Zn content. Principal component analysis regarding the variables fast leachable Zn, associated rate constant, total Zn, and market segment, has shown that 84.6% of variance is explained by two components, where the second component (24.0%) presented loadings only for the fast leachable Zn and associated rate constant. The proposed method is suitable for the fast evaluation (<1 h) of leaching kinetics and bioaccessibility in dry dog food.
