The Effectiveness of Scarification Technique to Break Dormancy Kenaf Seed (Hibiscus cannabinus L.)

Two hundred and forty (240), unsexed day old Arbor Acre broiler chicks were used to evaluate the effects of replacing whole kenaf (Hibiscus cannabinus L.) seed meal (WKSM) with full fat soybean meal (FFSM) in the diets on the performance and carcass characteristics of broiler chicken in a 2 x 4 factorial arrangement, consisting two processing methods (raw kenaf seed meal RKM and roasted kenaf seed meal HKM) and 4 inclusion levels (0%, 10%, 20% and 30%). Both RKM and HKM were analysed for anti-nutritive factors, data were collected on performance, carcass characteristics and cost benefit. The results of anti-nutritive factors (ANF) in RKM and HKM revealed that HKM had lower values of 0.045%, 0.029mg/g and 0.013mg/g for tannin, oxalate and phytic acid respectively when compared to 0.078%,0.124mg/g and 0.026mg/g obtained for RKM (P<0.05). The performance of broiler chicken showed that birds on 10% RKM with an average weight gain and FCR of (2640.00g and 2.48) competed favourably with the control (2554.67g and 2.45). The results of carcass characteristics showed that birds on 10% and 20% inclusion levels had significantly (P<0.05) higher values of 64.25% and 65.58% for dressed weight respectively. In terms of weight gain and FCR, birds fed RKM performed better than birds fed roasted kenaf meal HKM. About 5% feed cost savings was made when WKSM was included in the diets of broilers. It was concluded that RKM and RKM can replace FFSB in broiler diets up to 10% without any detrimental effect on performance and carcass quality.

Abstract A comparative study of the effect of different storage regimes of seeds (at + 5 ° С, -20 ° С and under deep freezing conditions at -196 ° С) of a valuable bast fiber culture - kenaf - Hibiscus cannabinus L. on their viability and the development of plants from them in field conditions. Freezing increases the laboratory and field germination of kenaf seeds, and also increases the energy of their germination. It did not cause the appearance of non-viable, ugly seedlings and plants, as well as their death. Plants went through a full development cycle and set full-fledged seeds. Biometric parameters of plants obtained from thawed seeds and control ones are very close. Cryopreservation is a promising way of storing seeds of the studied species, since it ensures longer periods of preservation of their viability.

Kenaf ( Hibiscus cannabinus L.) seed oil has been proven for its multi-pharmacological benefits; however, its poor water solubility and stability have limited its industrial applications. This study was aimed to further improve the stability of pre-developed kenaf seed oil-in-water nanoemulsions by using food-grade ternary emulsifiers. The effects of emulsifier concentration (1, 5, 10, 15% w/w), homogenisation pressure (16,000, 22,000, 28,000 psi), and homogenisation cycles (three, four, five cycles) were studied to produce high stability of kenaf seed oil-in-water nanoemulsions using high pressure homogeniser. Generally, results showed that the emulsifier concentration and homogenisation conditions had great effect ( p < 0.05) on the particle sizes, polydispersity index and hence the physical stability of nanoemulsions. Homogenisation parameters at 28,000 psi for three cycles produced the most stable homogeneous nanoemulsions that were below 130 nm, below 0.16, and above −40 mV of particle size, polydispersity index, and zeta potential, respectively. Field emission scanning electron microscopy micrograph showed that the optimised nanoemulsions had a good distribution within nano-range. The optimised nanoemulsions were proved to be physically stable for up to six weeks of storage at room temperature. The results from this study also provided valuable information in producing stable kenaf seed oil nanoemulsions for the future application in food and nutraceutical industries.

Kenaf Seed

Kenaf is an annual plant grown for its fibre which basically depend on the seed viability, for its maximum growth and production. The seed viability and vigor in turn depend on storage condition. There is insufficient information on physicochemical composition of kenaf seed in relation to seed viability. The present study was performed to know the physicochemical composition of the kenaf seed at different storage temperature in other to improve upon rapid loss of seed viability in kenaf. Four varieties of kenaf seed were obtained from I.A.R. & T seed unit. The seeds were stored at 00C (Unviable seed), 2.20C (Lower temperature), 350C (Ambient temperature), 280C (Cold room temperature which serve as control) for period of 8 months. Seed germination test and weight was performed before and after the experiment. Proximate analysis (Crude protein, Moisture, Carbohydrate, Ash, Crude fibre, Crude fat) and Phytochemicals (Total phenolics, Steroid and Total Flavonoids were also determined). The result shows that there is significant difference in all the parameters studied, for all the storage temperatures as compared with the control (280C) among the varieties except from ifeken 100 where the was no significant difference in Crude fibre and Ash content for seed under ambient temperature as compared with the control. However, the level of tolerance to different storage temperature among the varieties following the order Ifeken 400 >Tianung 2 > Cuba 108>Ifeken 100.Keywords: Kenaf, Storage, Seed germination, Seed weight, Temparature, Seed viability, Proximate, Flavonoid, Phenolics.

An experiment was conducted with 240, unsexed day old Arbor Acre broiler chicks to evaluate the benefit of replacing full fat soya (FFSM) with whole kenaf (Hibiscus cannabinus L.) seed meal (WKSM) in the diets on the haematology, serum biochemistry and organs weight of the broiler chicken in a 2 x 3 factorial arrangement, consisting two processing methods (raw kenaf seed meal RKM and roasted kenaf seed meal HKM) and 3 inclusion levels (10%, 20% and 30%). Blood samples were collected from the birds through the wing web vein for haematology and serum biochemistry, while sample of organs were collected from the birds after they were sacrificed after the 8 week feeding trials. Results showed that the processing methods significantly (p<0.05) influenced the mean values obtained for neutrophil and lymphocytes, while haemoglobin (Hb), total protein, globulin, uric acid, cholesterol, alanine amino transferase (ALT) (EC 2.6.1.2) and aspartate amino transferase (AST)(EC 2.6.1.1) were significantly influenced (p<0.05) by both processing methods and levels of inclusion. Weight of gizzard, spleen, lungs and heart were also influenced by both the processing methods and levels of inclusion of WKSM. The PCV, haemoglobin concentration and total protein values were within the range of 26.33 to 32.68%, 8.83 to 11.03g/dl and 37.70 to 50.43g/L. The results suggest that WKSM possess good dietary protein quality for optimal growth of broiler chicken. Inclusion levels above 20% to broiler will significantly alter the haematological and serum biochemical variables and probably induce anaemic conditions and dysfunction of visceral organs which can lead to their poor performance

Soaking Temperature

Kenaf (Hibiscus cannabinus L.) seed is rich in protein, fat, fiber, and other essential nutrients. Kenaf seed comprises of high protein (22–31%) and oil (22–25%) contents which suggested its high potential food application. This chapter discusses the potential and early development of kenaf-based plant-milk and tofu. The step-by-step processes involved in preparation of kenaf-based milk and kenaf-based tofu at laboratory-scale are illustrated. Soaking conditions (temperature and time) of kenaf seed as pretreatment in preparation of kenaf seed milk were highlighted. Hydration of kenaf seed were found to be faster at elevated temperature, however higher soaking temperature and prolonged soaking time causes some losses of protein (%) and solid content (%) which are unfavorable for production of highly nutritious plant-based milk. Furthermore, in preparation of kenaf-based tofu, soaking temperature of seed also affected the properties of the tofu. As the soaking temperature was increased from 25–65°C, the yield, hardness, and chewiness of kenaf tofu decreased. It was recommended that soaking of kenaf seed at 25°C and the use of aluminum potassium salt at 1.00 g% as coagulant produces kenaf-based tofu with optimum quality.

Kenaf (Hibiscus cannabinus) from the family Malvaceae, is a valuable fiber plant native to India and Africa and is currently planted as the fourth commercial crop in Malaysia. Kenaf seed oil contains alpha-linolenic acid, phytosterol such asβ-sitosterol, vitamin E, and other antioxidants with chemopreventive properties. Kenaf seeds oil (KSO) was from supercritical carbon dioxide extraction fluid (SFE) at 9 different permutations of parameters based on range of pressures from 200 to 600 bars and temperature from 40 to 80°C. They were 200/40, 200/60, 200/80, 400/40, 400/60, 400/80, 600/40, 600/60, and 600/80. Extraction from 9 parameters of KSO-SFE was screened for cytotoxicity towards human colorectal cancer cell lines (HT29) and mouse embryonic fibroblast (NIH/3T3) cell lines using MTS assay. KSO-SFE at 600/40 showed the strongest cytotoxicity towards HT29 with IC50of 200 µg/mL. The IC50for NIH/3T3 was not detected even at highest concentration employed. Cell cycle analysis showed a significant increase in the accumulation of KSO-SFE-treated cells at sub-G1 phase, indicating the induction of apoptosis by KSO-SFE. Further apoptosis induction was confirmed by Annexin V/PI and AO/PI staining.
