Aims and Scope
Shea butter is the under-consumed vegetable fat and oil. Making shea butter a part of food components in confectionaries would increase its utilization.
In this study, the cake was produced by incorporating shea butter as shortening.
Shea butter to margarine ratio was 100: 0, 50:50, 40:60, 30:70, and 0:100%, and additional cake samples were produced using flashed shea butter. Standard methods determined the physical and proximate properties of the cake samples, while 25-member panelists did the sensory evaluation. Statistical significance was done at p<0.05. The height, weight, and volume of the cake samples ranged from 3.2 to 3.9 cm, 39 to 50 g, and 625 cm3 to 1026 cm3, respectively. The ranges of moisture, fat, protein, carbohydrate, crude fiber, and the ash content of cakes were 13.7-17.3, 24.3- 30.7, 4.4-8.6, 43-50, 0.10-1.10, and 2.9-3.9%, respectively. The energy value of cake samples in kcal ranged from 440 to 471.
There was no significant difference (p>0.05) in the height and volume of the cakes produced from 100% shea butter and 100% margarine. The fat, crude fiber, and ash content increase with the increase in Shea butter substitution. There was no significant difference in the taste and appearance of cake samples from 100%, 70%, 60%, and 50% margarine.
Cake samples produced with 60% margarine and 40% shea butter were the most liked by the consumers. Acceptable cakes can be produced by the inclusion of up to 50% shea butter as part of the shortening.

Study on the Use of Evolved Gas Analysis FT-IR (EGA FT-IR) for the Evaluation of Cheese Volatile FractionMilena Povolo, Giovanni Cabassi, Mauro Profaizer, Silvia Lanteri
The analysis of volatile compounds for food products characterization is currently performed by gas chromatographic separation, often coupled with mass spectrometry. In our research the possibility of the application of the Fourier- transform infrared spectroscopy (FT-IR) technique to the cheese volatile fraction evaluation was investigated. An Evolved Gas Analysis (EGA) FT-IR prototype, developed to detect some volatile molecules released from bottle grade PET, was used. The preliminary step of the work was devoted to the set up of the best analytical conditions and instrumental parameters for cheese analysis. Thirty nine samples of PDO Bitto cheeses were analysed by both EGA FT-IR and Solid Phase Microextraction/Gaschromatography/Mass Spectrometry (SPME/GC/MS) technique. Satisfactory correlations were observed between the FT-IR spectra and the most abundant compounds detected by SPME/GC/MS. Even though some aspects of the analytical conditions need to be improved, the results obtained are promising for a possible application of EGA FT-IR in the evaluation of volatile fraction of foods.
