Durian Seed

This study was aimed at assessing the physicochemical and thermal properties of flour, acquired from the seeds of three native Sabah durian species. The three durian species concerned are the Dalit, Sukang and Pulu. Flour deriving from the seeds of the dalit (DDSF), sukang (DSSF) and pulu (DPSF) durian species, were put through a physicochemical, pasting and thermal characteristics assessment process. The protein content in flours, derived from the seeds of durian native to Sabah, demonstrated a high capacity for the absorption of both water (r = -0.855, p<0.01), and oil (r = 0.921, p<0.01). DPSF, which holds the most protein content at 6.92%, demonstrated the lowest water absorption capacity, and greatest oil absorption capacity (p<0.05). Moreover, DPSF was observed to have the lowest swelling power, solubility and peak viscosity (p<0.05). In terms of pasting temperature, no outstanding disparities were detected between the three durian seed flours (p>0.05), but they were considered to have high pasting temperatures. The lowest setback viscosity (p<0.05) displayed by DPSF, is an indication that the following gelatinization, will quickly dissolve. Additionally, the enthalpy ΔH of DPSF revealed as 0.29 J/g (p<0.05) is deemed significantly low. This undertaking delves into the physicochemical and thermal characteristics of durian seed flour, to its use as composite flour.

Jackfruit possess 100-400 seeds which are oval, brown and edible after processing. A study was undertaken to investigate ‘processing characteristics and acceptability of jackfruit seeds and to evaluate physical and functional properties of its flour’. Ripe jackfruits procured from a single tree at University of Agricultural Sciences, Dharwad campus were cut, and seeds were separated. Seeds were processed by boiling, pressure cooking, pan roasting, microwave roasting, baking. Unprocessed seeds served as control. Effect of processing on characteristics of jackfruit seed was evaluated. Seeds were subjected to sensory evaluation by semi- trained panel members using 9 point hedonic scale. Processed seeds were converted to flour and analyzed for physical and functional properties. Results revealed that weight, volume and edible portion of seeds increased in wet processing but decreased in dry processing. Boiling resulted in better acceptability with acceptability index of 83.15 per cent. Pressure cooked and pan roasted seeds were on par with boiled seeds followed by baked seeds, while microwave roasted seeds had lower acceptability. Flour yield was significantly higher in unprocessed jackfruit seeds (42.17 ± 0.06 %). Increase in bulk density was recorded with processing. All processing methods resulted in increased water absorption and oil absorption capacity of jackfruit seed flours. Swelling capacity of jackfruit seed flour increased during moist processing (6.46±0.11 % in boiled and 6.24±0.10 % pressure cooked seeds) and did not decrease significantly in dry processing. The solubility of flours increased during boiling (21.07±0.05%) and decreased significantly on dry processing (15.63 ± 0.20%). Jackfruit seed flour possess good functional property and hence can be used at domestic, commercial and industrial purpose KEY WORDS: Dry processing, Flour, Jackfruit seed, Moist processing

Durian seed flour content high protein, therefore it is potential to become food supplement (such as biscuits) for under five children. The purpose of this research was to formulate biscuit with durian seed flour as food supplement for underweight children under five in Kampar District, Riau. This was experimental research with Completely Randomized Design (CRD). The substitution of durian seed flour treatment was F1=15%, F2=20% dan F3=25%. ANOVA was used to analyzed the difference between groups and Duncan test for within groups. Semi-trained panelists consist of 25 undergraduate nutrition student of Universitas Pahlawan Tuanku Tambusai. There was no difference in flavor, color, and aroma of biscuit subsitute with durian seed flour. However, there was a difference in texture (p=0.000). Duncan test showed that F2 have a better acceptance level compared to F1 dan F3. Proksimat analysis for selected formula revealed that biscuit F2 contain 6.72% water, 1.36% ash, 5.57% protein, 13.75% fat, and 72.60% carbohydrate. Energy and protein content of F2 were 218 kcal and 2.7 grams per serving size (4 biscuits= 50 gram) and have met the 20% requirement of underweight children. Substitution of wheat flour with 25% durian seed flour has a similar organoleptic characteristics (flavor, color, and aroma) with wheat flour biscuits. Therefore, it can be a supplemetary food for underweight children. It is necessary to add other food ingredients to improve the texture and increasing the protein content in accordance with SNI.

The present research investigation was conducted to analyze the nutritional and functional properties of wheat, ragi and jackfruit seed composite flour. About 11 combinations were made using wheat, ragi and jackfruit seed composite flour with 100% wheat flour as control. 100% ragi and jackfruit flour was also added in the experiments for comparison. The combinations were optimized based on the proximate composition analysis and functional properties. The proximate composition analysis of wheat revealed the fact that jackfruit seed flour contains a higher amount of protein i.e.,13.9 g than wheat and ragi i.e., 11.45 g and 7.8 g respectively. Jackfruit seed flour contains lower fat i.e., 1.44 g as compared to wheat and ragi (2.27g and 1.78 respectively). Also, jackfruit seed flour contains low moisture 6.5% and ash content 0.96% than wheat (6.53% and 0.97%) and ragi (8.76% and 0.98%). The combinations of wheat, ragi and jackfruit seed flour in ratio of 80:10:10, 80:15:5, 70:10:20 and 60:20:20 showed good water and oil absorption capacity and emulsion stability and was found to be significantly different (p < 0.05) from the wheat flour alone. Based on nutritional and functional value, we selected 4 combinations for further studies. The selected flour combinations were used to prepare biscuits and muffins against 100% wheat products as control. Sensory evaluation indicated that incorporation of jackfruit seed flour in wheat up to 20%, significantly (p < 0.05) enhanced the taste, aroma and texture of biscuits. However, higher levels of jackfruit seed flour contributed to bitter taste in biscuits and thereby the products were rejected by the sensory panel. Further, the optimized biscuits showed superior antioxidant activity. This activity was significantly higher (p < 0.05) compared to the control samples. Muffins were prepared with two flour combinations of wheat: ragi: jackfruit seed flour in ratio of 80:10:10 and 80:15:5 owing to its high nutritional and functional property of which, muffins made in ratio of 80: 10:10 showed good taste, texture and aroma when compared to the other sample and the control (100% wheat flour).

The aim of this study was to analyze the content of functional tannins in grape pomace skin, seed, and mixed flour, from Feteasca Neagra and Italian Riesling varieties. Results showed that all compounds were present in the highest concentration in grape pomace seed flours and the lowest in skin flours. The concentration of total tannins and total flavan-3-ol monomers in all flour samples ranged from 37.34 to 72.28 mg epicatechin/g dry weight and 0.57 to 3.13 mg/g dry weight, respectively. Among monomers, (+)-catechin was found in the highest concentration, except in Italian Riesling seed flours, where (-)-epicatechin was predominant. The mDP of proanthocyanidins in seed flour (7.15 to 8.07) is lower than that of skin flours (10.83 to 18.43) while the opposite was observed for %G. As a result, all Feteasca Neagra and Italian Riesling grape pomace flours, especially seed flour, could be used as sources of functional tannins in alimentary or pharmaceutical industry.

AbstractDeveloping new approaches to improve the swelling, degradation rate, and mechanical properties of alginate hydrogels without compromising their biocompatibility for biomedical applications represents a potential area of research. In this work, the generation of interpenetrated networks (IPN) comprised from alginate–polyurethane in an aqueous medium is proposed to design hydrogels with tailored properties for biomedical applications. Aqueous polyurethane (PU) dispersions can crosslink and interpenetrate alginate chains, forming amide bonds that allow the structure and water absorption capacity of these novel hydrogels to be regulated. In this sense, this work focuses on studying the relation of the PU concentration on the properties of these hydrogels. The results indicate that the crosslinking of the alginate with PU generates IPN hydrogels with a crystalline structure characterized by a homogeneous smooth surface with high capacity to absorb water, tailoring the degradation rate, thermal decomposition, and storage module, not altering the native biocompatibility of alginate, providing character to inhibit the growth of E. coli and increasing also its hemocompatibility. The IPN hydrogels that include 20 wt.% of PU exhibit a reticulation index of 46 ± 4%, swelling capacity of 545 ± 13% at 7 days of incubation at physiological pH, resistance to both acidic and neutral hydrolytic degradation, mechanical improvement of 91 ± 1%, and no cytotoxicity for monocytes and fibroblasts growing for up to 72 h of incubation. These results indicate that these novel hydrogels can be used for successful biomedical applications in the design of wound healing dressings.
