“…Thus, whole grains are an 'excellent' source of nutrients rich in carbohydrates (29%), fibre/complex carbohydrates (12-14%), minerals (0.8-1.5%), as well as B vitamins (thiamin & niacin) and vitamin E (αtocopherol). Whole grains are also a 'good' source of protein (10-16%) and low in fat (1-3%) (5,6). Bernstein et al (7).…”

“…Triticale grains have a rich and desirable content of minerals and vitamins with generally higher levels of fibre and protein than wheat and rye respectively. The high protein content of triticale, as well as its generally higher levels of the amino acid lysine than that of barley and wheat, one of the limiting amino acids in cereal grains, provides the advantage of a decreased need for protein supplementation in the diet of ruminant animals (6,15,26,28,30). Although triticale starch content and fermentation is generally equal to that of other cereal grains(31), its digestibility is higher than barley and oats which is important for maximizing the availability of nutrients for growth (32).…”

Part of the solution to reducing the prevalence of chronic diseases is the employment of food as medicine. Whole grain consumption has been associated with a variety of health benefits owing to their bioactive constituents, namely fibre and phytochemicals. The overall aim of this study was to discover the underlying mechanisms behind the positive physiological effects of whole grains and further elucidate their nutritional value. In particular, the bioactive properties of alkylresorcinols (ARs), phenolic lipids present almost exclusively in cereal grains, and soluble dietary fibre, potential prebiotics, were investigated using triticale bran (TB), an underestimated cereal crop.Specific objectives were met through the following projects. Conditions for large-scale extraction of ARs from cereal grains were optimized using response surface methodology (RSM). Isolation ofARs for 16-24 h at a solid-to-solvent ratio of 1:40 (weight per volume) and temperature of 24 °C produced the highest yield with the least amount of co-extractives/unknowns. The antioxidant and anti-inflammatory activities of ARs were evidenced by in vitro model systems, ORAC, DPPH, and COX assay whereby results were in agreement with ex vivo model systems, RAW 264.7 macrophage cell cultures induced by AAPH or LPS. Subsequently, the in vivo effects of ARs were evaluated and oxidative stress markers in liver and heart tissues of mice supplemented 0.5% ARs and mice fed 10% TB demonstrated antioxidant protection. Additionally, water extractable polysaccharides (WEP) from cereal samples were isolated by varying treatments;the highest yield with the least amount of impurities was achieved by boiling water extraction followed by successive enzyme treatments, dialysis and successive ethanol fractionations. Using yogurt as fermentation model, probiotic yogurt in the presence of TB produced significantly higher TTA values, lower pH levels, and improved microbial viability compared to controls. In addition to the prebiotic potential of TB, likely owing to its high fibre content, isolates of WEP also demonstrated antioxidant activity as measured by ORAC assay.First and foremost, I would like to thank my academic supervisor Dr. Farah Hosseinian for this incredible and life changing opportunity that has helped me learn and grow as a researcher, student, teacher, team player, and as an individual overall. I am very fortunate to have a supervisor like Dr. Hosseinian who encouraged me to work hard and push forth during trying times. She gave me confidence in my abilities, guidance, and shared all of her knowledge and wisdom while still challenging me to push myself beyond my perceived limits.

Cereals such as triticale may contain high levels of xylans and arabinoxylans, limiting its use in diets since they act as anti-nutritional factors. The objective was to evaluate the effects of the enzyme xylanase included in triticale-based diets on productive performance, digestibility, carcass traits and meat quality in growing-nishing rabbits. Eighty rabbits (New Zealand X California breed), 35 days old, with an average initial live weight of 821 ± 26 g, were used. Twenty animals for treatment were used in each one of the fourth experimental treatments: 0, 4000, 8000 and 12000 XU/kg of xylanase inclusion (XilaBlend 6X). The rabbits were fed ad libitum and fecal excretion was collected on days 7, 14, 21, 28 and 35 of the experimental period. At the end of the experimental period, the rabbits were slaughtered and carcass characteristics and meat quality were measured. A higher (P < 0.05) live weight was observed in rabbits fed diets with the addition of xylanase enzyme on days 4 and 7 of the experimental period. On the other hand, in the average total tract digestibility of organic matter, no signi cant difference (P > 0.05) was observed, similar to what occurred in the carcass traits and nutritional quality of the meat (P > 0.05). The inclusion of 8000 XU/kg of xylanase enzyme provided the best values of apparent digestibility of total tract protein and dry matter on the nished stage of rabbits.
