棕榈调和油在香辣酱中的应用

棕榈油因其产量高、油源稳定和价格具有竞争性,同时具有良好的氧化稳定性和营养特性,被广泛应用于食品工业及化学工业领域。棕榈油熔点相对较高,在低温条件下易发生凝固从而影响食品的感官特性。将不同熔点的棕榈油与大豆油和菜籽油混合,并测定其冷冻稳定性。在此基础上开发棕榈油基香辣酱。通过研究与辣椒酱制作相关的因素,进行单因素试验与正交试验分析,确定了香辣酱配方:混合植物油47%、辣椒粉13%、白砂糖1%、酱油2%、味精1%、辣椒酱33%、食盐1%、大蒜1%和生姜1%。其中植物油的配方为:菜籽油:棕榈油(12℃)=8:2或RSO:PO(8℃)=7:3。     

二甲醚-棕榈油混合燃料发动机的试验研究

The traditional system of oil palm wine production in Igbo Eze local government area of Anambra state of Nigeria

This study was carried out in the Igbo Eze Local Government Area of the Anambra State of Nigeria, approximately 100 km from Enugu, the state capital. Four of the sixteen communities that make up the Local Government Area were selected by random sampling. From each of the four communities, a village was selected at random and from each of those four villages, a random sample of fifty farmers was drawn.The system of oil palm wine production in the area of study can be described as traditional in the sence that it is based on methods which have been in operation for generations. The palms available for tapping are the wild palms, most of which are old and of dwindling productivity.Empirical evidence showed that the tappers had not been exposed to any changes in organisational structure or institutions concerned with the oil palm smallholder rehabilitation scheme which could be utilised to improve the productivity of their palms. Nonetheless, the traditional system provides the farmer-tappers with some means of livelihood.Being market-oriented, the farmers are keen on adopting innovations which promise increased palm wine yields and increased farm incomes. Government assistance, through the provision of credit on liberal terms to enable the farmers to improve and modernise their holdings, as well as the introduction of new oil palm varieties with increased yield potential, should be considered.     

Making a living: Land pressures and changing livelihood strategies among oil palm settlers in Papua New Guinea

Since the establishment of oil palm land settlement schemes (LSSs) in West New Britain Province, Papua New Guinea, the settler population has increased significantly as second-generation settlers marry and raise families on their parents’ blocks. We explore how settlers are responding to demographic and socio-economic change in an environment in which opportunities for land-use change are limited. In the context of rising population pressure, LSS smallholders are developing innovative livelihood strategies by pursuing non-farm income sources, increasing food production, acquiring additional land and migration. The type of migration or land accumulation strategy depends on household access to various resources, especially social and kinship networks, and capital. Agricultural extension and rural development policies have not yet responded to this socio-agronomic transformation. We conclude that economic diversification amongst smallholders creates new opportunities for the oil palm industry to formulate more innovative and sustainable policies that strengthen the oil palm industry in PNG while facilitating broad-based rural development.     

Mechanised production system of oil palm produce in Nigeria: A preliminary study on the establishment of location-allocation models

This paper describes a basic study preceding the establishment of location-allocation models for a government-controlled agricultural industry. The need to develop an efficient and low cost production system for the Nigerian oil palm industry is established. The peculiar handling techniques of oil palm produce are outlined and the requirement of location-allocation models for this industry is discussed. Data were collected in Nigeria and the relevant cost and distance functions were developed for the models.It is necessary to emphasise that this paper contains the pre-requisites for the establishment of location-allocation models. The techniques for establishing these models have been discussed by the author elsewhere.     

Hydrological impact of biofuel production: A case study of the Khlong Phlo Watershed in Thailand

This study evaluates the potential impact of increased biofuel production on the hydrology of a small watershed, Khlong Phlo, in the eastern part of Thailand. The water footprint of biofuel energy was estimated for three crops in order to identify the most water-efficient crop. The Soil and Water Assessment Tool (SWAT) model was used to evaluate the impact of land use change (LUC) caused by the expansion of biofuel crops on the components of water balance and water quality in the studied watershed. Several LUC scenarios consisting of oil palm (biodiesel), cassava and sugarcane (bio-ethanol) expansion were evaluated. The water footprint results indicated that cassava is more water-efficient than the other two crops considered. Simulation results revealed that although oil palm expansion would have negligible alteration in evapotranspiration (0.5 to 1.6%) and water yield (−0.5 to −1.1%), there would be an increased nitrate loading (1.3 to 51.7%) to the surface water. On the contrary, expansion of cassava and sugarcane would decrease evapotranspiration (0.8 to 11.8%) and increase water yield (1.6 to 18.0%), which would lead to increased sediment (10.9 to 91.5%), nitrate (1.9 to 44.5%) and total phosphorus (15.0 to 165.0%) loading to surface water. Based on the results, it can be concluded that land use change for biodiesel production would affect water quality, while both the water balance components and water quality would be affected by the expansion of bio-ethanol crops. Overall, the study indicates that biofuel production would have a negative impact on the water quality of the studied watershed. Further research at large scale (e.g. basin level) and on the economic aspect is recommended, in order to contribute to developing suitable land use and energy policies.
