1.大豆精选与浸泡选用优质大豆为原料,剔除沙石、木屑等杂物。浸泡豆水比例为1︰3.5,确保大豆充分吸水膨胀;泡豆水pH值为10~12时,有助于提高大豆蛋白溶解度。泡豆时间根据水温不同而异,一般浸泡时间为8~12小时,水温高可相应减少浸泡时间,但水温不宜超过25℃,否则泡豆水容易变酸,对提取大豆蛋白不利。 相似文献

Estimating the Potential Benefits of New Health Claims in Canada: The Case of Soluble Fiber and Soy Protein

Growing awareness of the link between diet and health has spurred growth in the functional food sector. Health Canada regulates allowable health claims on food products, and in recent years has approved health claims linking the consumption of soluble fiber from barley (2012) and psyllium (2011) to reduced/lower low‐density lipoprotein (LDL)‐cholesterol levels, a major risk factor for heart disease. A health claim linking consumption of soy protein to reduced risk of coronary heart disease (CHD) is still under consideration. Using a cost‐of‐illness approach, this paper estimates the potential economic benefits of allowing health claims for soluble fiber and soy protein in terms of reductions in the direct and indirect costs of CHD. Parameters for the economic analysis are drawn from a meta‐analysis of scientific studies examining the effect of soluble fiber and soy protein on LDL‐cholesterol levels, as well as other scientific literature. While a barley soluble fiber health claim yields nontrivial benefits in a base case scenario equal to CAD$105 million annually and ranging from $42 million to $238 million in low and high scenarios, the potential benefits of a soy protein health claim appear to be several magnitudes larger at $549 million annually in the base case and ranging from $220 million to $1.25 billion in low/high scenarios. Given the relatively slow regulatory approval process for new health claims, there may be value in using economic estimates of potential gains to help prioritize health claims approval processes. 相似文献

In this paper we present a framework for understanding regional land use processes by incorporating the concept of agglomeration economies into agricultural frontier theory. We show that agricultural firms can obtain positive externalities from locating in close proximity to other agricultural firms, leading to agglomeration economies. Agglomeration economies lead to high levels of competition and diversity within a local agricultural supply chain and influence local prices, information flows, and private enforcement of environmental institutions. We use the theory of agglomeration economies to understand the development of soybean production in two counties along the Santarém-Cuiaba (BR-163) highway in the Brazilian Amazon: Santarém, Pará and Sorriso, Mato Grosso. We conclude that differences in environmental and land tenure institutions influenced the occurrence of agglomeration economies in these two counties, which in turn affected the total factor productivity of soy in each region. In particular, the supply chain became extremely competitive and diverse in Sorriso where few environmental regulations existed, while environmental restrictions reduced the diversification of the supply chain in Santarém. The presence of a soy agglomeration economy in Sorriso spurred innovation, increased productivity, and led to extremely rapid soy expansion in that county, while the monopolistic supply chain in Santarém reduced producers’ access to land and capital and impeded soy expansion. 相似文献

This paper attempts to (1) shed some light on the EC – US controversy concerning the effect of the EC oilseeds market regime on EC imports of US soybean products, essentially soy meal, and (2) provide information on another EC – US controversy: Does corn-gluten feed behave as a substitute for (EC view) or a complement to (US view) feed grains, and do EC corn-gluten feed imports displace EC grain production or not? By using a constrained vectorial autoregressive model of Rotterdam prices for soy meal, sunflower meal, rape meal, corn-gluten feed and cassava, we show that (1) the decrease in EC imports of US soymeal are mot mainly caused by the EC milling subsidies, and (2) corn-gluten feed is both a substitute for soymeal due to its protein content and a substitute for cassava (and grains) due to its energy content: US and EC views are only partial views. 相似文献

This paper challenges the recent hailing of agricultural biotechnology as a panacea for food insecurity and rural poverty in countries of the global South. Based on an empirical investigation of the neoliberal soy regime in Paraguay, I document how the profound transformation of this country's agricultural mode of production over the past two decades, spurred by the neoliberal restructuring of agriculture and the biorevolution, has jeopardized rural livelihoods. In particular, I demonstrate how the transgenic soyization of Paraguay's agriculture has led to an increased concentration of landholdings, as well as the displacement and disempowerment of peasants and rural labourers who have been rendered surplus to the requirements of agribusiness capital. At the same time, the consolidation of this new agro‐industrial model has fostered a growing dependence on agrochemicals that compromise environmental quality and human health. Thus, I argue, a development policy based on industrial monocropping of genetically modified (GM) soy is inappropriate, unsustainable and unethical. 相似文献

This paper explores the unequal distribution of the environmental and social costs and benefits of the genetically modified (GM) soy model in Argentina and its impact on grievance formation and the emergence of contestation. In the 1990s, Argentina transitioned into a neoliberal agro‐industrial model based on producing GM soy for export. Though celebrated as a success, the expansion of GM soy monocultures has brought widespread socio‐ecological disruption. Various social actors have started to mobilize against the resulting environmental injustice. I focus on the peasant–indigenous movement in the north of the country, which is struggling for land rights, and the movements against agrochemical spraying in the central Pampas region. These groups, which are relatively powerless to control resources where they live, and that experience little or no benefit from GM soy production, nevertheless bear most of its social and ecological costs. These struggles link environmental and social well‐being, becoming struggles for ecological sustainability as well as social justice and equity. 相似文献

Perhaps for the first time, this paper applies Johansen and Juselius' methods of the cointegrated vector autoregression (VAR) model to a monthly US system of markets for soybeans, soy meal, and soy oil. Analysis of the error correction or cointegration space illuminates the empirical nature of policy-relevant market elasticities, and of effects of important policy, market, and institutional events on US soy-related markets. A statistically strong US demand for soybeans emerged as the primary cointegrating relation in the error-correction space. 相似文献
