Pramita DS, Handajani S, Rachmawanti D. 2008. The effect of heating technique to phytic acid content and antioxidant activity of velvet bean (Mucuna pruriens), butter bean (Phaseolus lunatus) and jack bean (Canavalia ensiformis). Biofarmasi 6: 36-44. Koro is a kind of local bean which has many varieties. The nutrition of koro is not different with soy, especially carbohydrate and protein which high enough, and has a low-fat content. However, koro also contains some harmful compounds, HCN which poisoned and phytic acid which an antinutritional compound. Besides as antinutritional compound, phytic acid has a positive role, i.e. as an antioxidant. Besides phytic acid, legume also contains the compounds of phenol and vitamin E that have antioxidant activity. The aims of this research were to determine the contents of phytic acid and antioxidant activity, and to determine the effect of heating technique on phytic acid and antioxidant activity of velvet bean, butter bean, and jack bean. The materials used were velvet bean, butter bean and jack bean obtained from Batuwarno, Wonogiri, Central Java. This research used a Completely Randomized Design (CRD) with five kinds of treatment, each treatment consisted of three replications. The treatments given were soaking by 3 days (P1), steaming (P2), boiling (P3) and pressure cooker (P4), which compared to a raw bean without heating treatment (P0). The investigated factors were phytic acid and antioxidant activity (DPPH Radical Scavenging Ability method). The results of this research showed the phytic acid content of velvet bean, butter bean and jack bean from the treatment of P0, P1, P2, P3 and P4 were degraded. The phytic acid of velvet bean of P0, P1, P2, P3 and P4 treatment were 10.87, 8.94, 4.56 and 1.72 and 1.46 mg/db, respectively; on butter bean were 11.78, 8.75, 4.77, 1.73 and 1.61 mg/db, respectively; while on jack bean were 9.04, 1.99, 1.39, 1.42 and 1.21 mg/db. The result of variance analysis showed the phytic acid content was significantly different (p<0.05). Antioxidant activity showed the increase from P0 to P1, then the degradation process at P2, P3, and P4. Antioxidant activity at velvet bean were 74.10%, 86.49%, 84.73%, 83.59% and 79.51%, respectively; at butter bean were 4.5%, 7.19%, 6.07%, 6.30% and 6.28%, respectively; at jack bean were 14.64%, 8.55%, 5.84%, 5.17% and 3.58%. The result of variance analysis showed antioxidant activity at velvet bean and jack bean was significant, while at butter bean for P1, P2, P3, and P4 were not significant. The conclusion that could be taken away from this research were heating techniques had an effect on the degradation of phytic acid at all kind of bean used, and also had an effect on the antioxidant activity at velvet bean and jack bean.

Rokhmah LN, Anam C, Handajani S, Rachmawati D. 2009. Study of phytic acid and protein contents during velvet beans (Mucuna pruriens) tempe production with variation of size reduction and fermentation time. Biofarmasi 7: 1-9. Velvet bean is one species of Leguminoceae containing phytic acid. The advantage of phytic acid is for antioxidant. Nevertheless, phytic acid has shortage, i.e. antinutritional. Phytic acid has characteristic that it can be provided from protein to form insoluble complex of phytate and protein. The formation of phytate-protein complex causes decreasing protein availability for human body so reducing the nutrition value of the food product. The aims of this research were to determine the influence of size reduction of velvet beans seed (Mucuna pruriens) and the fermentation time on the contents of phytic acid and soluble protein on the production of velvet bean (Mucuna pruriens) tempe. This research is a factorial experiment that arranged in a Randomized Complete Design (RCD) with two experimental factors including size reduction (3 kinds) and the time of fermentation (5 kinds). Every 12 hours fermentation time for three kinds of velvet beans seed size, the lowest phytic acid and the highest soluble protein were showed by velvet bean tempe from grinded seeds. On the fermentation time of 36 hours for three kinds of seeds size resulted in a lowest phytic acid during fermentation, i.e. 3.32 mg/g, 1.98 mg/g, and 1.16 mg/g, respectively. The contents of highest soluble protein during fermentation obtained on fermentation for 36 hours were 19.51 mg/g, 23.73 mg/g, and 24.89 mg/g. The fermentation time and the size of velvet bean seeds affected on phytic acid and soluble protein contents of velvet bean tempe. The longer fermentation time of velvet bean tempe caused a lower phytic acid content and a higher soluble protein content. The smaller size of velvet bean seeds on tempe caused a lower phytic acid content and a higher soluble protein content. The velvet bean tempe of grinded seeds with 36 hours fermentation had the lowest of phytic acid content and the highest of soluble protein content of all samples with the variation of reducing size and the duration of fermentation. The optimally time fermentation was recommended at 36 hours prior to solid texture, and the soluble protein and the phytic acid content on 48 fermentation were not significant.

Hybrid Sunflower

The objective of this work was to investigate the germination of hybrid sunflowers BRS191 and C11 as a means of lowering phytic acid (PA) content by enhancing the activity of endogenous phytase and acid phosphatase. The concentration of PA in hybrid sunflower achenes varied from 2.16 to 2.83g/100g of sample (p < 0.05). The phytase and acid phosphatase activities of sunflowers BRS191 and C11 were the highest on the 4th and 5th days of germination, respectively, with the release of the phosphorus. These results indicated that hybrid sunflower PA reduced and enhance phytase activity at distinct germination periods, which could open up the possibility of applying these enzymes in the control of PA content in cereals, thus improving their nutritional value.

Iron And Calcium

Linseed (Linum usitatissimum L.) is considered as a nutritious food because of exceptionally high alpha-linolenic acid (ALA) content, dietary fiber, quality protein and phytoestrogens. It is rich in minerals (100 g of seeds contain 350-431 mg of magnesium and 236- 250 mg of calcium) and has very low amount of sodium. It also contains anti-nutritional factors, especially phytic acid that interferes with the bioavailability of nutrients like calcium and iron. Fermentation increases the nutritional quality of foods by reducing anti-nutritional factors. Probiotic cultures viz., Lactobacillus acidophilus, Bacillus mesentericus and lactic acid bacterial isolate LAB-3 were used to produce fermented linseed beverage and the quantity of phytic acid, bioavailability of iron and calcium were estimated. Bioavailability of iron and calcium increased by fermentation. The highest bioavailable iron and calcium were observed in L. acidophilus fermentation (4.40 mg and 250.41 mg /100 g seeds, respectively) followed by LAB-3 and Bacillus mesentericus compared to raw seeds that contain 0.89 mg of iron and 125 mg of calcium /100g of seeds. Phytic acid content was high in raw seeds (1392 mg /100 g seeds) and fermentation with L. acidophilus recorded 856 mg phytic acid /100 g seeds resulting in 38.51 % reduction. LAB-3 and B. mesentericus showed approximately 32 % reduction in phytic acid content. The reduction in phytic acid content is significantly high. Fermentation using probiotic bacteria enhanced the bioavailability of iron and calcium by reducing phytic acid. Hence, this study leads to a conclusion that, microbial intervention can be adopted to reduce the anti-nutritional factors and enhance the nutritional quality of linseed.
