全谷物保留了完整谷粒所具备的营养成分,经常食用有助于维持健康体重,还可以降低心血管疾病、Ⅱ型糖尿病、肠道癌症等疾病的患病风险。但全谷物的适口性和烹饪特性差,难以被消费者接受,因此,改良传统加工工艺,开发新的全谷物食品十分必要。谷物茶作为一种全谷物食品,不仅改善了全谷物的口感,而且保留了其营养价值和健康功效。文章主要对谷物茶在烘烤、发芽、发酵等不同加工工艺下的风味物质变化、功能特性进行综述,并重点探讨了谷物茶在加工过程中丙烯酰胺、晚期糖基化终末产物等有害物形成机制及抑制方法,旨在为全谷物饮品的开发利用提供理论依据。 相似文献

Purported health benefits of whole grain foods in lowering risk of obesity, type 2 diabetes, cardiovascular disease, and cancer are supported by epidemiological studies and scientific researches. Bioactive components including dietary fibers, phytochemicals, and various micronutrients present in the bran and germ are commonly considered as the basis for such benefits. Endosperm starch, as the major constituent of whole grains providing glucose to the body, has been less investigated regarding its nutritional property and contribution to the value of whole grain foods. Nutritional quality of starch is associated with its rate of digestion and glucose absorption. In whole grain foods, starch digestion and glucose delivery may vary depending on the form in which the food is delivered, some with starch being rapidly and others slowly digested. Furthermore, there are other inherent factors in whole grain products, such as phenolic compounds and dietary fibers, that may moderate glycemic profiles. A good understanding of the nutritional properties of whole grain starch is important to the development of food processing technologies to maximize their health benefits. 相似文献

Obesity and chronic diet‐related diseases such as type 2 diabetes, hypertension, cardiovascular disease, cancers, and celiac are increasing worldwide. The increasing prevalence of these diseases has led nutritionists and food scientists to pay more attention to the relationship between diet and different disease risks. Among different foods, rice has received increasing attention because it is a major component of billions of peoples’ diets throughout the world. Rice is commonly consumed after polishing or whitening and the polished grain is known a high glycemic food because of its high starch content. In addition, the removal of the outer bran layer during rice milling results in a loss of nutrients, dietary fiber, and bioactive components. Therefore, many studies were performed to investigate the potential health benefits for the consumption of whole brown rice (BR) grain in comparison to the milled or white rice (WR). The objective of this work was to review the recent advances in research performed for purposes of evaluation of nutritional value and potential health benefits of the whole BR grain. Studies carried out for purposes of developing BR‐based food products are reviewed. BR safety and preservation treatments are also explored. In addition, economic and environmental benefits for the consumption of whole BR instead of the polished or WR are presented. Furthermore, challenges facing the commercialization of BR and future perspectives to promote its utilization as food are discussed. 相似文献

Sprouting induces activation and de novo synthesis of hydrolytic enzymes that make nutrients available for plant growth and development. Consumption of sprouted grains is suggested to be beneficial for human health. Positive consumer perceptions about sprouted cereals have resulted in new food and beverage product launches. However, because there is no generally accepted definition of “sprouting,” it is unclear when grains are to be called sprouted. Moreover, guidelines about how much sprouted grain material food products should contain to exert health benefits are currently lacking. Accordingly, there is no regulatory base to develop appropriate food labeling for “sprouted foods.” This review describes the nutritional and technological properties of sprouted grains in relation to processing conditions and provides guidelines to optimize sprouting practices in order to maximize nutritive value. Relatively long sprouting times (3 to 5 days) and/or high processing temperatures (25 to 35 °C) are needed to maximize the de novo synthesis and/or release of plant bioactive compounds. Nutrient compositional changes resulting from sprouting are often associated with health benefits. However, supportive data from clinical studies are very scarce, and at present it is impossible to draw any conclusion on health benefits of sprouted cereals. Finally, grains sprouted under the above‐mentioned conditions are generally unfit for use in traditional food processing and it is challenging to use sprouted grains as ingredients without compromising their nutrient content. The present review provides a basis for better defining what “sprouting” is, and to help further research and development efforts in this field as well as future food regulations development. 相似文献

Whole flaxseed (flour) as a good source of omega-3 fatty acid and phytochemicals with excellent nutritional and functional attributes has been used to enrich foods for health promotion and disease prevention. However, several limitations and contemporary challenges still impact the development of whole flaxseed (flour)-enriched products on the global market, such as naturally occurring antinutritional factors and entrapment of nutrients within food matrix. Whole flaxseed (flour) with different existing forms could variably alter the techno-functional performance of food matrix, and ultimately affect the edible qualities of fortified food products. The potential interaction mechanism between the subject and object components in fortified products has not been elucidated yet. Hence, in this paper, the physical structure and component changes of flaxseed (flour) by pretreatments coupled with their potential influences on the edible qualities of multiple fortified food products were summarized and analyzed. In addition, several typical food products, including baked, noodle, and dairy products were preferentially selected to investigate the potential influencing mechanisms of flaxseed (flour) on different substrate components. In particular, the altered balance between water absorption of flaxseed protein/gum polysaccharides and the interruption of gluten network, lipid lubrication, lipid–amylose complexes, syneresis, and so forth, were thoroughly elucidated. The overall impact of incorporating whole flaxseed (flour) on the quality and nutritional attributes of fortified food products, coupled with the possible solutions against negative influences are aimed. This paper could provide useful information for expanding the application of whole flaxseed (flour) based on the optimal edible and nutritional properties of fortified food products. 相似文献

谷物碾磨技术的发展促进了粮食加工的精细化进程,但长期精白面制品的摄入造成了营养不均衡,高血压、糖尿病和心脑血管疾病的发病率逐年增加。全麦粉含有小麦籽粒中的所有组分,富含膳食纤维、维生素和矿物质等生理活性物质,具有降低血糖、抗氧化、清除自由基和增强免疫力等功效,因此以全麦粉制成为原料制成的全麦食品是改变膳食结构,改善健康水平的理想选择。对比了全麦粉与精白面粉的营养组成差异,总结了全麦粉的特征营养素如膳食纤维、酚酸、不饱和脂肪酸、植物甾醇、木脂素等,从减重、预防2型糖尿病和干预心脑血管疾病等三个方面综述了全麦食品的健康功效,还对全麦烘焙类、蒸煮类和油炸类食品的品质改良方法进行了总结,以期为全麦食品的继续开发和推广提供理论和实践参考。 相似文献

全谷物是膳食纤维和酚类物质等功能成分的重要来源之一,有效摄入全谷物可降低现代人群患糖尿病、高血脂、高血压等慢性疾病风险。但全谷物具有复杂的亚宏观多层级结构,麸皮层部分不溶性膳食纤维含量较高,酚类也多以结合态共价连接于果胶及半纤维壁,导致全谷物及相关制品存在可溶性差、食用口感不佳、功能营养组分热加工损失多等问题。作者总结了全谷物中膳食纤维和酚类物质的含量与分布、存在形态和潜在的健康效益,探讨了发芽、发酵、挤压、3D打印、超微粉碎及其他复合处理等生物与物理绿色加工技术对全谷物宏微观结构、感官品质及膳食纤维、酚类物质的影响。 相似文献

Grains are important sources of carbohydrates in global dietary patterns. The majority of these carbohydrates, especially in refined-grain products, are digestible. Most carbohydrate digestion takes place in the small intestine where monosaccharides (predominantly glucose) are absorbed, delivering energy to the body. However, a considerable part of the carbohydrates, especially in whole grains, is indigestible dietary fibers. These impact gut motility and transit and are useful substrates for the gut microbiota affecting its composition and quality. For the most part, the profile of digestible and indigestible carbohydrates and their complexity determine the nutritional quality of carbohydrates. Whole grains are more complex than refined grains and are promoted as part of a healthy and sustainable diet mainly because the contribution of indigestible carbohydrates, and their co-passenger nutrients, is significantly higher. Higher consumption of whole grain is recommended because it is associated with lower incidence of, and mortality from, CVD, type 2 diabetes, and some cancers. This may be due in part to effects on the gut microbiota. Although processing of cereals during milling and food manufacturing is necessary to make them edible, it also offers the opportunity to still further improve the nutritional quality of whole-grain flours and foods made from them. Changing the composition and availability of grain carbohydrates and phytochemicals during processing may positively affect the gut microbiota and improve health. 相似文献
