This work consists of studying the influence of the desamerization of the mesocarpe on the chemical composition and the sensorial quality of the jam, based on the bitter orange. The results of the various analysis show that desamerization decreases acidity, sugars, protein, and bioactive compound levels (carotenoids, polyphenols, and vitamin C), but desamerized jams still remain an important source of antioxidant compounds with antioxidant potential in the diet. Concerning the sensory analysis of the jams, the results show that the jam desamerized with water presents the same bitterness as the bitter jam and that the salt significantly reduces the bitterness of the jams.

Sprouts are generally accepted as a pro-healthy food. They are consumed as a source of valuable macronutrients, antioxidants, microelements, and vitamins. Changing growth conditions of sprouts enables modification of their nutritional quality, as well as their safety. Thus, in order to achieve the most desirable composition of the produced sprouts, the conditions for their production are optimized. The aim of this review is to present methods currently used to modify the nutritional quality of plant sprouts. Most scientific works focus on stress conditions inducing the synthesis of secondary metabolites, mainly antioxidants. An increase in their content is achieved after application of physical (e.g., light illumination, temperature) or chemical factors (e.g., salinity stress, phytohormones, metal ions, etc). Though the application of these modifications on a larger scale is problematic. These problems include difficulties in predicting the effect of the stressor and an increased price of the obtained sprouts. However, since it is possible to enrich sprouts with valuable health-promoting substances, these methods are still considered very promising.

The aim of this study was to evaluate the quality of model homogenized sterilized canned meat products produced with wheat fiber preparations (WF 200 R or WF 600 R) with different fiber lengths used in the amount of 3% or 6% by weight of the batter. Basic chemical composition (water, protein, fat, collagen and salt content), pH level, water activity, thermal drip, CIEL*a*b* color components, texture parameters (TPA, shear force) and sensory quality were determined. The addition of 3% or 6% of wheat fiber preparations did not affect the basic chemical composition, water activity and pH of products. The 6% addition of both fiber preparations caused lightening of the color of the meat blocks. Products with the addition of both wheat fiber preparations were characterized by significantly (p ≤ 0.05) higher hardness than the control product. Sensory quality of products, except tastiness, with the addition of wheat fiber preparations did not differ from the control product. There was no significant effect of wheat fiber length on the quality of meat blocks. Both lightening the color of canned meat blocks produced with the addition of wheat fiber preparation, as well as increasing their hardness, is desirable and contributes to increasing the quality of products.

<p>Biochemical composition appears to be influenced by both genetic factors and plant growth conditions. The main objective of this study was to evaluate the biochemical composition of selected Ruiru 11 sibs and its relationship with cup quality. Thirty four (34) Ruiru 11 sibs grown in three different locations in Kenya were used in this study. The experiment was laid out in a Randomized Complete Block Design with three replications. Coffee cherries were picked during the peak harvesting period between 2009 and 2011. The cherries were wet processed and graded into different grades based on size, shape and density. Fifty (50) grams of the dry coffee beans per sib per replication were frozen at -80 ºC before grinding (&lt; 0.5 mm particle size) in liquid nitrogen as specified by the Association of Official Analytical Chemists (AOAC). The samples were packed in small plastic bottles and stored at -80 ºC awaiting extraction of biochemical components. Caffeine, trigonelline and total chlorogenic acids were extracted and purified using classical methods and analysed using High Pressure Liquid Chromatography (HPLC). For the lipids, the sample was subjected to Soxhlet extraction using n-hexane. The study demonstrated the existence of high variation in biochemical composition among Ruiru 11 sibs. Significant correlations were observed between biochemical and cup quality traits indicating that biochemical composition plays a major role in determining the sensory quality of coffee. The growing environment was also found to have an effect on biochemical composition as portrayed by high locational variations.</p>

The effect of frying temperatures ranging from 150-180 °C and frying time of 3-12 mins on the compo-sition and sensory quality of sweetpotato crisps from white-fleshed and yellow-fleshed varieties were investigated in this study. Chemical composition, sensory properties and overall acceptability of the crisps were determined using standard methods. Results obtained showed moisture content (2.37-7.50%), fat (9.77-16.22%), total sugar (1.52-4.44%), carotenoids (31.65-55.29 μg/100 g), free fatty acid (0.11-0.44%) and peroxide values (2.95-12.30 mEq/kg). Each of the chemical components and sensory attributes of the crisps were significantly (p<0.001) affected by the individual and combined effects of variety, frying temperatures and frying duration (time) in minutes. The highest overall accept-ability scores were 8.46 for yellow-fleshed crisps fried at 170 °C/5 min and 7.84 for white-fleshed crisps fried at 180 °C/5 min.
