Peanut Hull and Arjuna Tree Bark Powders as Potential Functional Ingredients in Development of Low-Fat, High-Fibre Pork Patties

Due to a growing demand for functional fermented dairy foods with improved nutritional qualities, the food processing industry has prompted to cut down on ingredients such as fat, sugar and additives, thereby necessitating some important changes in sensory qualities that influence consumer acceptance of fermented dairy products. Addition of functional ingredients such as whey protein concentrate (WPC) and honey may improve overall quality of yoghurt. It is well known ability of WPC to support formation of whey protein aggregates which highly improve physical properties of yoghurt. Honey may be an ideal sweetener for yoghurt due to its sugar concentration, low pH and a variety of beneficial nutritional properties.The aim of the present study was to examine the effect of WPC (1%), as well as combination of WPC and honey (H: 2% and 4%) on the physical and chemical properties of low fat set-style yoghurt during 21 days of storage at 5°C. Yogurt was prepared from milk (1.5% fat), treated on 95ºC for 10 min and yoghurt culture VIVOLAC DriSet Yogurt 442: 10% Lactobacillus delbrueckii subsp. bulgaricus and 90% Streptococcus thermophilus (Vivolac Culture Corporation, Indiana, USA), applying standard manufacturing procedure. It was concluded that the addition of honey in combination with WPC improved quality of produced yoghurt. On the other side, as honey presents a higher nutrition value ingredient, the addition of different percent of honey in combination with WPC could present a novel formulation for functional fermented dairy food.

Dietary Switch

How dietary patterns impact colonic bacterial biosynthesis of vitamins and utilization by humans is poorly understood. Our aim was to investigate whether a reciprocal dietary switch between rural South Africans (traditionally high fibre, low fat) and African Americans (Western diet of low fibre, high fat) affects colonic folate synthesis. Colonic evacuants were obtained from 20 rural South Africans and 20 African Americans consuming their usual diets at baseline. For 2 weeks thereafter, rural South Africans were provided with a Western diet (protein, 27%; fat, 52%; carbohydrate, 20%; and fibre, 8 g/day) and African Americans were provided with a high fibre, low-fat diet (protein, 16%; fat, 17%; carbohydrate, 63%; and fibre, 43 g/day). Colonic evacuants were again collected. No difference between groups at baseline in the folate content of 3-h evacuants was observed. The high-fibre, low-fat diet consumed by African Americans during the intervention produced a 41% increase in mean total folate content compared with baseline values (p = 0.0037). No change was observed in rural South Africans consuming a Western diet. Mean total folate content of colonic evacuants was higher among African Americans at the end of the dietary switch (3107 ± 1811 μg) compared with rural South Africans (2157 ± 1956 μg) (p = 0.0409). In conclusion, consistent with animal studies, switching from a Western diet to one higher in fibre and lower in fat can be expected to result in greater colonic folate content. Future research should confirm that these observations are not transitory and understand the contribution of transit-time to the findings.
