“…It has previously been reported that higher concentrations of total soluble iron at pH 1–3 can guarantee sufficient bioaccessibility of iron in the stomach , and solubility of Fe-containing salts at pH 1 is a good predictor of in vivo iron uptake by rats . Therefore, we explored soluble Fe(II) and total Fe concentrations from these salts in solution under gastric-like conditions (incubating at pH 2 and 37 °C for 75 min , ) by the ferrozine assay . Additionally, Figure S7 of the Supporting Information shows that the accuracy of the total iron estimation utilizing the ferrozine assay was confirmed through comparison with ICP-AES.…”

Poorly water-soluble iron-containing compounds are promising iron fortificants. However, ensuring high bioaccessibility and low reactivity of iron is challenging. We present the potential application of ferrous pyrophosphate (Fe(II)PP) and Fe(II)-containing M 2(1−x) Fe 2x P 2 O 7 salts (0 < x < 1, M = Ca, Zn, or Mn) for delivery of iron and a second essential mineral (M). After preparation by a facile and environment-friendly coprecipitation method, the salts were investigated for their composition, pHdependent dissolution, iron-mediated discoloration of a black tea solution, and oxidation of vitamin C. Our results suggest that these salts are possible dual-fortificants with tunable composition that compared to Fe(II)PP (i) show lower (<0.5 mM) and enhanced (to 5 mM) iron dissolution in moderate and gastric pH, respectively, (ii) exhibit less discoloration and dissolved iron in tea when x = 0.470 for M = Ca or Zn and x = 0.086 for M = Mn, and (iii) do not increase the oxidation extent of vitamin C over 48 h when x = 0.06, 0.086, or 0.053 for M = Ca, Zn, or Mn, respectively.

“…Cultures of Lactobacillus spp. consumed with Dutch-type cheese increased Mg (~18%) and Ca (~2.5%) availability in vitro [ 28 ]. Similarly, fermented goat milk containing Lactobacillus plantarum increased Mg bioavailability compared to commercial fermented goat milk [ 21 ].…”

“…Macroelements that diffuse into the semi-permeable dialysis membrane are potentially absorbed into the bloodstream, known as dialysate. Using a dialysis membrane eliminates the problems that occur during the dialysis of soluble and insoluble compounds [ 28 ]. The solution remaining inside the dialysis membrane is the sample component potentially absorbed into the bloodstream.…”

To determine the potential bioavailability of macroelements (Ca, Mg, P, K), probiotic ice cream samples (Lactaseibacillus paracasei L-26, Lactobacillus casei 431, Lactobacillus acidophilus LA-5, Lactaseibacillus rhamnosus and Bifidobacterium animalis ssp. lactis BB-12) from sheep’s milk with inulin, apple fiber and inulin, or apple fiber and control samples were submitted to in vitro digestion in the mouth, stomach and small intestine. The bioavailability of calcium in the ice cream samples ranged from 40.63% to 54.40%, whereas that of magnesium was 55.64% to 44.42%. The highest bioavailability of calcium and magnesium was shown for the control samples. However, adding 4% inulin reduced the bioavailability of calcium by about 3–5% and magnesium only by about 5–6%. Adding 4% apple fiber reduced the bioavailability of calcium by as much as 6–12% and magnesium by 7–8%. The highest bioavailability of calcium was determined in ice cream with L. paracasei, and the highest bioavailability of magnesium was determined in ice cream with L. casei. The bioavailability of phosphorus in ice cream ranged from 47.82% to 50.94%. The highest bioavailability of phosphorus (>50%) was in sheep ice cream fermented by B. animalis. In the control ice cream, the bioavailability of potassium was about 60%. In ice cream with inulin, the bioavailability of potassium was lower by 3–4%, and in ice cream with apple fiber, the bioavailability of potassium was lower by up to 6–9%. The bioavailability of potassium was significantly influenced only by the addition of dietary fiber. The results of the study confirmed the beneficial effect of bacteria on the bioavailability of Ca, Mg and P.

“…Through the analysis of trace elements in the cicada slough of the Cryptotympana atrata, the results showed that there were 24 trace elements in the cicada slough, including 16 essential elements for the human body, among which aluminum had the highest content of 2750 ppm [19]. The nymph of the Cryptotympana atrata is rich in macro and trace elements, such as K, Fe, Mn and Zn, among which the iron content is the highest, up to 60.74 mg/100 g. The iron content in the Cryptotympana atrata is significantly higher than that in pork, eggs, milk, grass carp and other foods [20,21]. The above results all indicate that the Cryptotympana atrata has a nutritional and edible value.…”

As an important resource insect, the Cryptotympana atrata is widely distributed in the eastern and central parts of China. The cicada slough is one of the traditional crude drugs in East Asia, and the main component is polysaccharide, which has the functions of anti-convulsion, relieving asthma and improving lipid metabolism. The parasitoid fungus Cordyceps cicadae, which grows inside the cicada nymphs and forms the fruiting bodies on the surface of the host’s carcass, is also known as the “cicada flower” in China. The Cordyceps cicadae is another old, traditional Chinese medicine, which has been used as a tonic and medicine to nourish and regulate human immunity for centuries. For the further development and utilization of the golden cicada, this paper summarized the C. atrata from the aspects of their biological characteristics, distribution area, life cycle, history of edible and medicinal use, edible methods and nutritional compositions; emphatically introduced the edible and potential medicinal value of the C. atrata; and specifically expounded the research progress of its application. As one popular insect food, the prospects for the development of C. atrata have also been put forward, especially in artificial breeding technology, food safety risk assessment and medicinal value utilization.
