  • The objective of this study is to establish an efficient celll culture system for somatic embryogenesis in Ostericum koreanum and Angelica purpuraefolia. The highest frequency of embryogenic callus on immature seeds of O. konanum and A, purpuraefolia. was obtained when seeds were cultured on MS medium containing 0.1 mg/L 2,4-D and 0.1 mg/L BA. However somatic embryos were formed directly from the edge of cotyledon and hypocotyl of plant which regenerated on medium supplemented with 0.1-3.0 mg/L NAA. Immature seed explane cultured at 25$\pm$2$^{\circ}C$ after 10 days treatment at 5$^{\circ}C$ produced embryogenic callus and somatic embryos, and these differentiated into whole plane. Addition of glutamine and coconut milk to media did not enhance the frequency of somatic embryogenesis in immature seed cultures of A. purpuraefolia. However in immature seed culture of O. koreanum, the frequency of somatic embryogenesis were increased on media supplemented with glutamine and 10% coconut milk. Especially addition of glutamine to the medium substituted effect of NH$_4$N0$_3$ in constast to coconut milk. The highest frequency of conversion somatic embryos into plantlet was 89.1% on MS basal medium Embryogenic calli were grown vigorously when maintained on medium with 0.01 mg/L 2,4-D and 0.01 mg/L BA.

  • The antioxidant activities and quality characteristics of Matcha (powdered green tea) spreads containing coconut milk were evaluated. Matcha spreads containing coconut milk was prepared with different amounts (0, 4, 8, 12, and 16 g) of Matcha, and indicated as S1, S2, S3, S4 and S5, respectively. The moisture content, viscosity, color, pH and sugar content were influenced by the concentration of Matcha. Total phenolic content and total flavonoid content of Matcha were found to be 226 mg GAE/g and 809.42 mg QE/g respectively. Also, 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activity and reducing power of Matcha was found to be $5.76{\mu}g/mL$ ($IC_{50}$) and 2.26 O.D., respectively. The antioxidant activities of the Matcha spreads containing coconut milk increased with increasing concentration of Matcha. Sensory evaluation indicated that S3 (8 g) was the most preferred in terms of color, taste, texture, and overall acceptance. Based on these results, it is suggested that S3 (8 g) was appropriate for achieving good quality coconut milk based spread containing Matcha.

  • The relevance and importance of buffalo production under coconut plantations in the North Westen Province of Sri Lanka was studied in three districts (Bingiriya, Pannala, Kuliyapitiya). The objective of the study was to collect baseline information on socioeconomic and cultural aspects of buffalo production, with a view to promote and disseminate new technologies. The survey technique used consisted of a formal survey using a structured questionnaire (71 households) and rapid appraisal (55 households). The results indicate the existence of a wide stratification of dariy farmers which ranged from skilled dairy operators with high levels of production and management of efficiency to marginal subsistence farmers with low levels of productivity. The most frequent family size of households ranged from 4-5 members (58%), and the average family size was 4.7. The actual average land ownership accounts to 2.4 ha of upland and 0.5 ha of lowland, but when their accessibility to common property resources are taken into account, the land availability was assessed at 13 ha and 0.7 ha of upland and lowland, respectively. The highest average monthly income (Rs. 13,590) was received by farmers with off-farm employment (primary) who are also engaged in livestock production (secondary), and livestock contributed 43% of the total income. Livestock farmers who practised integrated crop farming as a secondary source of income received a monthly income of Rs. 10,843, and those involved in crop production as the primary source received the lowest average income (Rs. 7,295). The survey revealed a high investment cost on concentrate feeds (47%) for milk production. However some farmers obtained higher milk yields (11 litres/cow/day) at lower ration costs, and this could be attributed to the entrepreneurship skills and management efficiency. The study area had a well developed market infrastructure for fresh milk, principally due to the existence of the Nestle's company and the Coconut Triangle Milk Union. On an average the producer collected Rs. 10 per litre of milk marketed.

  • This study evaluated the impact of an AI heifer calf rearing scheme on dairy stock development, in a coconut grazing and a peri-urban smallholder dairy production system in the Western Province of Sri Lanka. The heifer rearing scheme included free advice on calf rearing, drugs, acaricides, minerals and subsidised concentrates for 30 months. The farmers in the coconut growing area integrate dairying with their plantation, they sell their milk to the main processors. The peri-urban farmers are intensive milk producers, who sell their milk at informal markets. To estimate the effect of the heifer rearing scheme on dairy replacement stock development, scheme farmers were compared with farmers who did not participate in the scheme. Calf mortality was twice as high in non-scheme farms (23-28%) as in scheme farms (12-14%). The scheme had a positive effect on weight development and scheme heifers calved 4.5 months earlier than non-scheme heifers. The calf rearing package is cost effective in both farming systems, however, the required cash inputs are a major constraint. The costs per in-calf heifer under the scheme are much lower than the production of such animals by either multiplication in state farms or importing them. The coconut grazing system showed the highest potential for producing surplus dairy stock.

  • A survey involving 71 cattle and buffalo farming households under coconut plantations was carried out in three districts (Pannala, Bingiriya and Kuliyapitiya) with the aim of assessing the status of livestock farming. Also, 24 households (eight from each district) were visited monthly for period of one year to collect information on feeding practices. Apart from milk, animals were reared for selling, draught, bio-gas and for manure. Due to difference in system of management of cattle and buffaloes, manure from buffaloes (46%) was more frequently used for coconuts than that from cattle (10%). Majority of cattle were improved breeds (temperate origin) or their crosses, as compared to buffaloes (mainly indigenous). The most predominant management system was tethered grazing during the day, and stall feeding during the night. Coconut land (own or others) and paddy fields were the major grazing areas for the animals. The grass from coconut land was lower in crude protein (8.2%) and digestibility (48%) compared to those from paddy fields (12.1 and 57%, respectively). Of the 288 rations analysed, grass was included in 280 of the daily rations for cattle as compared to 251 for buffaloes. Straw was more commonly included in mixed rations for buffaloes (137 out of 288) than for cattle (53 out of 288). The frequency of use of straw for buffaloes was high in Pannala (75 out of 137 cases). There was wide variation among the improved breeds of cattle and buffaloes in milk production (2 to 9 litres/day), lactation length (6 to 10 months) and calving interval (13-21 months).

  • This study was performed to investigate the effect of palm or coconut solid lipid nanoparticles (PO-SLNs or CO-SLNs) on growth of Lactobacillus plantarum (L. plantarum) in milk during storage period. The PO or CO (0.1% or 1.0%) was dispersed both in distilled water (DW) and ultra high temperature milk (UHTM), and subsequently emulsified with Tween® 80 by ultrasonication (30% power, 2 min). Increase in particle size and encapsulation efficiency (EE%) in DW was observed with an increase in oil concentration, whereas a decrease in ζ-potential of SLNs was noted with an increment in oil concentration. Moreover, the CO-SLNs exhibited relatively smaller particle size and higher EE% than PO-SLNs. The CO-SLNs were found to be more stable than PO-SLNs. Higher lipid oxidation of PO or CO-SLNs in UHTM was observed during the storage test, when compared to PO or CO-SLNs in DW. However, there was no remarkable difference in lipid oxidation during storage period (p>0.05). In the growth test, the viability of L. plantarum in control (without PO or CO-SLNs in DW) exhibited a dramatic decrease with increasing storage period. In addition, viability of L. plantarum of PO or COSLNs in UHTM was higher than that of SLNs in DW. Based on the present study, production of SLNs containing PO or CO in UHTM is proposed, which can be used in lactobacilli fortified beverages in food industry.

  • Productivity of bacterial cellulose by Acetobacter xylinum GS11 was investigated in the several culture conditions. In various carbon sources, others with the exception of glucose were not found to be effective for cellulose production, and 2% was better in yield than other concentration of glucose. Yeast extract and soytone among several organic nitrogens were effective, but inorganic nitrogen sources tested were not efficient for cellulose production by A. xylinum GS11. The effects of various inorganic salts, amino acids and vitamins were also investigated: $MgSO_4$, phenylalanine and $\alpha$-tocopherol gave the cellulose yield of 1.5, 1.4 and 1.4 fold, respectively, compared with basal medium. In our experiment, cellulose production by A. xylinum GS11 added with 10% coconut milk and 0.5% lignosulfonate in basal medium, was the most efficient among the several material sources employed here, and these were 2.2 and 2.1 fold, respectively.

  • To develop new elicitors inducing the high productivity of taxane derivatives, plant growth inhibitors, namely, maleic acid hydrazide, N-phosphomethyl glycine and succinic acid 2.2-dimethyl hydrazide, coconut milk and yeast extract were administrated in the cell suspension culture system of Taxus cuspidata, and the production of baccatin III were analysed. The effects of amino acid related with the biosynthesis of baccatin III were also examined in these culture system. As the results, a remarkable enhancement of baccatin III production was observed in the cultivation with coconut water and with maleic acid hydrazide.

  • Effects of Ph on the activity of lipase isolated from milk fat globules were investigated, using coconut oil and homogenized milk as substrate. With buttermilk as an enzyme source for coconut oil and homogenized milk substrates bell-shaped curve was observed at $37^{\circ}C$, having the highest activity at pH 9.5. However, lipase activity at $0^{\circ}C$ continuously increased up to pH 10.0. With the purified lipase for homogenized milk substrate, the bell -shaped curve and the highest activity were observed at $37^{\circ}C$ and pH 9.0, respectively. Lipase activity at $0^{\circ}C$ increased up to pH 10.0. The addition of bovine serum albumin to the coconut oil shifted the optimum pH to pH 9.5 and the activity remarkably declined at pH 10.0. The effect of pH on the stability of purified lipase was depending on the temperature. Wehn the lipase kept at $37^{\circ}C$ for 20 minutes, it's activity remarkably declined as pH increased: the activity at pH 10.0 was declined by 13% of that pH 8.5. However, when the lipase kept at $4^{\circ}C$ for 60minutes, the activity was stable within the range of pH 7.5 to 10.0.
