Flaxseed is emerging as an important functional food ingredient because of its rich contents of α-linolenic acid (ALA, omega-3 fatty acid), lignans, and fiber. Flaxseed oil, fibers and flax lignans have potential health benefits such as in reduction of cardiovascular disease, atherosclerosis, diabetes, cancer, arthritis, osteoporosis, autoimmune and neurological disorders. Flax protein helps in the prevention and treatment of heart disease and in supporting the immune system. As a functional food ingredient, flax or flaxseed oil has been incorporated into baked foods, juices, milk and dairy products, muffins, dry pasta products, macaroni and meat products. The present review focuses on the evidences of the potential health benefits of flaxseed through human and animals’ recent studies and commercial use in various food products.

Flax and flaxseed oil: an ancient medicine & modern functional food.

Flaxseed is one of the most important oilseed crops for industrial as well as food, feed, and fiber purposes. Almost every part of the flaxseed plant is utilized commercially, either directly or after processing. The stem yields good quality fiber having high strength and durability. The seed provides oil rich in omega-3, digestible proteins, and lignans. In addition to being one of the richest sources of α-linolenic acid oil and lignans, flaxseed is an essential source of high quality protein and soluble fiber and has considerable potential as a source of phenolic compounds. Flaxseed is emerging as an important functional food ingredient because of its rich contents of α-linolenic acid (ALA), lignans, and fiber. Lignans appear to be anti-carcinogenic compounds. The omega-3s and lignan phytoestrogens of flaxseed are in focus for their benefits for a wide range of health conditions and may possess chemo-protective properties in animals and humans. This paper presents a review of literature on the nutritional composition of flaxseed, its health benefits, and disease-prevention qualities, utilization of flaxseed for food, feed, and fiber, and processing of flaxseed.

Flaxseed: a potential source of food, feed and fiber.

Staling of bread is cause of significant product waste in the world. We reviewed the literature of the last 10 y with the aim to give an up-to-date overview on processing/storage parameters, antistaling ingredients, sourdough technology, and measurement methods of the staling phenomenon. Many researchers have been focusing their interest on the selection of ingredients able to retard staling, mainly hydrocolloids, waxy wheat flours (WWF), and enzymes, but different efforts have been made to understand the molecular basis of bread staling with the help of various measurement methods. Results obtained confirm the central role of amylopectin retrogradation and water redistribution within the different polymers in determining bread staling, but highlighted also the importance of other flour constituents, such as proteins and nonstarch polysaccharides. Data obtained with thermal, spectroscopy, nuclear magnetic resonance, X-ray crystallography, and colorimetry analysis have pointed out the need to encourage the use of one or more of these techniques in order to better understand the mechanisms of staling. Results so far obtained have provided new insight on bread staling, but the phenomenon has not been fully elucidated so far.

Bread Staling: Updating the View

Development of gluten-free bread using tartary buckwheat and chia flour rich in flavonoids and omega-3 fatty acids as ingredients.

Development of Chinese steamed bread enriched in bioactive compounds from barley hull and flaxseed hull extracts

Effects of ground flaxseed on bread quality, staling, and in particular on γ-tocopherol and unsaturated fatty acid composition were determined. Ground flaxseed was added in concentrations of 10, 15, 20, and 25% to wheat flour sample. Results showed that the use of ground flaxseed at a 10% level markedly increased loaf volume, specific loaf volume, Dallman degree and retarded bread staling. Oil and γ-tocopherol content and proportion of linolenic acid in fatty acid composition went up as the ratio of flaxseed flour in bread formulation was increased. Oil, γ-tocopherol content, and proportion of linolenic acid in fatty acid varied in the range of 1.48—8.20%, 0.2—0.24 g/kg sample oil, and 50.25—55.55%, respectively in breads enriched with flaxseed flour. During bread staling, the change in peroxide values, γ-tocopherol content, and fatty acid distribution were not significant. Bread samples were tested for crust color appearance, crumb color, shape-symmetry, external appearance, mouth feel, and taste-aroma. ...
