Raw versus heated mesquite flour
Common annual legumes such as peas, beans, soybeans contain proteins in their seeds with strong anti nutritional properties. Fortunately by heating these legume seeds, the proteins are denatured and the anti-nutritional properties are avoided. Common anti-nutritional proteins are called trypsin inhibitors and phytohemagglutinins. Trypsin is an enzyme in the intestinal system that breaks proteins down into smaller pieces so they can be digested and absorbed as amino acids. The trypsin inhibitors prevent this enzyme from working. Phytohemagglutinins are proteins that cause agglutination of red blood cells.
According to the Wilkipedia encyclopedia (http://en.wikipedia.org/wiki/Phytohemagglutinin), as few as 5 uncooked kidney beans (Phaseolus vulgaris) can cause severe nausea and diarrhea 3 hours after eating. The Food and Agricultural Organization of the United Nations has published a compendium "Amino Acid content of foods and Biological data on Proteins" (FAO, 1970). This compendium reports values for the Protein Efficiency Ratio of proteins from various sources in mixtures with other food sources, with supplementation with limiting amino acids and before and after cooking. The Protein Efficiency Ratio (PER) is obtained by feeding rats a diet of 10% of the protein being examined and measuring the weight gain after 30 days. The maximum value of 4 is assigned to the henÕs egg which has the best balance of amino acids for humans. To illustrate the importance of denaturing these anti-nutritional factors by heating, the FAO compendium lists raw soybean flour as having a PER of 0.54 and heat processed soybean flour to have a PER of 2.39. Generally pressure cooking for 15 minutes destroys the anti nutritional factor and maximizes nutritional value.
There is evidence for these anti-nutritional factors in mesquite. For example, Pak et. al., (1977) were the first to report trypsin inhibitors and phytohemagglutinins in the seeds of a Prosopis from Chile (P. tamarugo). Harden and Zolfaghari (1988) reported trypsin inhibitors in the seeds of Texas mesquite although at quite low levels. Oliveira et al., (2002) isolated and characterized the trypsin inhibitor from Prosopis juliflora in Brazil with the objective of using this protein as a bioinsecticide defense against insects and pathogens for the protection of bean seeds.
Mesquite flour preparations that are made from grinding the entire pod without heat treatment will have intact anti-nutritional factors. If this flour is incorporated into products that will be baked or cooked, there will be no effect of the anti-nutritional factors. However if the entire flour is eaten raw, these anti-nutritional factors could result in nausea and diarrhea.
The preparation method used for Casa de Fruta mesquite flour eliminates the anti-nutritional factors in two important ways. First, the seeds and the leathery capsule surrounding the seeds are eliminated by a combination of milling and sieving steps. This is done to obtain the most flavorful and aromatic part of the pod, which is the pulpy portion between the seed and the outer portion of the pod. Second, the pods are heated at about 130F for 4 hours to remove the water so the high sugar content pods can be ground to a fine flour.
Casa de Fruta has carefully examined the scientific literature to provide you with the product with the greatest aroma and flavor while doing everything possible to eliminate potential health risks. We hope you enjoy your mesquite flour experience. For further questions, please send a message to our web site.
