The residue generated from the preparation of a juice obtained from purslane (Portulaca oleracea L.), a Non-conventional edible plants (NCEP), can contribute to the enhancement of biodiversity and to sustainable production, without waste. Thus, this work aimed to evaluate the levels of calcium, the bioaccessible fraction of this mineral in the residue generated from the preparation of juice from aerial parts (leaves, seeds and stems) of purslane, as well as the content of oxalic acid (an antinutrient which can complex with calcium, reducing its bioaccessibility, in addition to forming oxalate crystals in the kidneys). The residue was freeze-dried for 48 hours, packed in vacuum packaging and stored in a freezer at -18°C until analysis. For the determination of calcium, digestion in an acidic medium was performed, and for quantification, a flame atomic absorption spectrometer (FAAS) was used. Oxalic acid extraction was performed according to Naik et al. (2014), added a precipitation step (Adeneyi et al., 2014), with modifications. Oxalate quantification was performed by FAAS. To estimate the bioaccessibility of minerals in the soluble fraction, the Infogest static method was used. The lyophilized residue showed 742.9 ± 6.8 mg. 100g-1 of calcium, a content considered high for this essential element in fruit and vegetables. However, it was found that calcium was not present in the bioaccessible fraction. This result may be associated with the high content of oxalic acid found in the residue (5.55± 0.74 g. 100g-1 on a wet basis), which, by forming a complex with calcium, may consequently have reduced the bioaccessibility of this essential element. Thus, it would be interesting to carry out treatments on the sample that can reduce the content of this antinutrient, and increase the bioaccessibility of this mineral, so that it is possible to add value to this by-product.
