Effects of the addition of mechanically deboned poultry meat and collagen fibers on quality characteristics of frankfurter-type sausages.

The effects of mechanically deboned poultry meat (MDPM) and levels of collagen fibers on comminuted, cooked sausage quality characteristics were investigated using the central composite rotatable design of response surface methodology (RSM). Use of collagen fiber as an additive affected the sausage characteristics, but the effect depended on the amount of the MDPM used. While MDPM additions resulted in higher cooking loss and darker and redder frankfurters, the addition of collagen fibers improved cooking yields and contributed to the lightness of the final product. Higher collagen fiber content was also accompanied by a significant increase in frankfurter hardness regardless of the MDPM content. Use of collagen fibers countered the negative effects of MDPM on sausage quality attributes, especially on cooking yields and final product color.

Effect of different ingredients contents on physical, physicochemical and sensory properties of the creamy banana marmalade cv. ‘nanica’(Musa cavendishii)

Banana is a highly perishable fruit, with a shelf life of 7 to 10 days, and the fruits being in excess or those in non conformity to be consumed are used to produce marmalade; and it is an interesting economic alternative. This study evaluated the effect of different ingredients on the physical, physicochemical and sensory properties of creamy banana marmalade. An incomplete factorial design (24-1) with two levels of four factors (pulp/sugarratio, pectin concentration, added amount of acid and sorbate concentration). The sensorial acceptance of marmalades was evaluated using a 9-point hedonic scale, and the purchase intention by employing a 5-pointscale. The analyzed variables mostly affecting the parameters were the pulp/sugar ratio, the added amount of acid and the sorbate concentration, due to their reaction with the marmalade components. The formulation 2 was preferred by consumers because of the firmest texture and the intensified yellow color.
