“…The protein content of RPI was similar to canola protein isolate (Mwachireya et al, 1999), but more than those reported by for rapeseed protein isolate (Nagel et al, 2012), pea protein isolate (Schulz et al, 2007), canola protein isolate (Slawski et al, 2013) and jatropha protein isolate . Isolating the proteins from rubber kernel meal resulted in a significant increase in the protein content and reduction in the antinutritional factors as reported by other researchers in different studies (Devappa and Swamylingappa 2008;Saetae and Suntornsuk, 2010;Nagel et al, 2012;Kumar et al, 2012;Slawski et al, 2013). The higher in vitro digestibility of RPI recorded in this study may be due to the significant reduction in the soluble and indigestible carbohydrates, antinutritional factors, and more accessibility of amino acid peptide bonds by the digestive enzymes as reported by Devappa and Swamylingappa (2008).…”

“…Isolation of protein is one of such approach by separating the pure protein fractions from other non-proteinaceous components present in the ingredients including antinutritional factors (Mwachireya et al, 1999;Devappa and Swamylingappa, 2008;Saetae and Suntornsuk, 2010;Wanasundara, 2011), thus improve the digestibility and nutrient utilization. In the present study, the protein content of the isolated protein (RPI) from rubber kernel meal was found to be 908 g kg −1 with a concomittant reduction in the cyanide contents (64.3%), phytic acid (51.1%), tannin (92.4%) and insoluble carbohydrate.…”

“…The wet protein isolate was lyophilized (Scanvac TM cool safe 100-9 pro), and the final protein content was found to be 908 g Kg −1 (Table 1). Amino acid analysis was carried out following the method described by Devappa and Swamylingappa (2008), and quantitfied by High performance liquid chromatography (HPLC). …”

a b s t r a c tThe nutritional potential of protein isolate from rubber seed (RPI) in the diets of Labeo rohita (initial average weight 4.45 ± 0.01 g) was assessed in a 60 days feeding trial. Five isonitrogenous (32.62 ± 0.13 CP Kg −1 ) and isocaloric (18.47 ± 0.08 MJ kg −1 ) experimental diets were formulated with graded level of RPI like 0%, 25%, 50%, 75%, or 100% in replacement for soybean protein isolate (SPI), and designated as Control, RPI25, RPI50, RPI75, RPI100, respectively. The RPI contributed 0%, 13%, 26%, 39% or 52% of the total dietary protein in the diets. Each diets were randomly assigned to 15 experimental tanks containing 12 fish in triplicates and fed to satiation twice daily at 10:00 h and 18:00 h. At the end of the feeding trial, the growth performance and nutrient utilization indices such as percent weight gain (WG%), specific growth rate (SGR), daily growth coefficient (DGC), feed intake (FI), protein efficiency ratio (PER), feed conversion ratio (FCR) and protein retention (PR) values were not significantly (p > 0.05) affected by the dietary treatments irrespective of inclusion levels of RPI. A significantly higher (p < 0.05) hepatosomatic index (HSI) was recorded in the control and RPI 50 group compared to other treatment groups (p < 0.05). The intestinal somatic index (ISI) and Survival rate were similar (p > 0.05) in all the groups. The apparent digestibility coefficients (ADCs) of dry matter and protein for fish fed the control and RPI 100 diets were found to be similar, while RPI 50 and RPI 75 groups exhibited a significantly lower value corresponding to the protease enzyme activity. The whole body compositions and digestive/metabolic enzymes activities among the various groups did not differ significantly (p > 0.05). The serum cholesterol and triglyceride levels were found to be significantly higher (p < 0.05) in the control compared to the RPI fed groups. Significantly higher serum glucose level was recorded in RPI 50, while a reverse was seen in the liver glycogen contents. Overall, this study clearly showed that RPI from rubber seed can serve as alternative protein source in the diets of L. rohita fingerlings without any adverse effects on growth, nutrient utilization and physio-metabolic responses.

Chikki, a popular Indian traditional sweet snack prepared from peanut was enriched with protein, minerals and vitamins by incorporating soy protein isolate, calcium carbonate, ferrous fumerate, vitamin A and folic acid to meet the growing demand for health foods. The enriched nutra chikki was evaluated for physico-chemical characteristics such as moisture, texture, peroxide value (PV), fatty acid composition in comparison with control peanut chikki. Nutra chikki, which had initial moisture content of 2-3%, did not alter much up to 60 days of storage at 27°C and 37°C. PV increased gradually at 27°C, whereas at 37°C, it was higher. Hardness of nutra chikki did not change significantly when stored at 27°C up to 105 days, but at 37°C a gradual increase in hardness was observed after 45 days. These results of nutra chikki were similar and comparable with those of control chikki. Nutra chikki had 18% protein, 20% fat, 6.42% Ca, 1.7% Fe, 4000 μg vitamin A and 2660 μg folic acid. Protein digestibility corrected amino acid score of nutra chikki was 0.78 whereas that of control chikki was 0.73. The fatty acid composition of control and nutra chikki was same as both contain peanuts as oil source. The formulation and process parameters for preparation of protein, mineral and vitamin enriched peanut chikki, were standardized. The storage stability and quality parameters of enriched chikki were comparable with those of control chikki.

Purpose The objective of this study was to identify the availability, possible applications, and economic potential of proteins that are present in different parts of the rubber tree. Proteins from non-food sources can be used in e.g. animal feed or biochemicals production with no or little competition with food production, rendering them important biobased feedstock. Rubber tree is primarily grown for its latex that is used in rubber production. Indonesia has the largest rubber plantation area that is mostly owned and run by smallholder farmers. Using non-latex fractions from the rubber tree may generate additional income, and increase the economics of rubber plantations in general. Methods Several biomass streams from the rubber tree and subsequent latex processing were considered. Data were compiled from literature, a case study, and interviews with researchers, smallholder farmers, and managers at rubber processing plant and plantation. Results Latex waste streams, seeds, and leaves were considered to have the highest potential based on the amount of available proteins, and processes to isolate proteins from these streams were proposed. Isolation of specific functional properties from natural sources requires complex (and expensive) separation processes and therefore only economically feasible when specific use of the protein(s) for high value applications can be identified. Purification of many interesting proteins from latex fractions has already been described. Processing of seeds and leaves may also yield useful proteins for food, other purposes, and also still unknown high value applications. Conclusions A biorefinery concept can be applied to obtain multiple products from the seeds and leaves, and protein extraction can be performed with available knowledge and technology. Small scale processing can be more beneficial for the farmers, especially if the products are used locally for feed.
