“…The method of dry ash digestion and analysis as described by Schachter and Boyer (1980) and modified by IITA ( 2002) was used to determine the mineral content of the Energy bars. A weighed quantity (0.52g) was put into a clean ceramic crucible.…”

The objectives of this research are as follows: to develop an "energy" snack bar from blend of high quality cassava; toasted bambara groundnut and roasted cashew kernel flours, to determine the mineral composition as well as the sensory characteristics of the energy snack bars. The minerals properties evaluated were calcium (Ca), sodium (Na), magnesium (mg) and potassium (K). The sensory parameters studied were taste, crumb appearance, aroma, chewiness, fracturability and general acceptance. Augmented simplex lattice design method of response surface methodology as provided by design Expert statistical software (version 11) was used for the generation of the design matrix. Fourteen formulations were generated. These formulations revealed single, binary and ternary combinations of high quality cassava flour, toasted bambara groundnut flour and roasted cashew kernel flour. The developed "energy" snack bars contain 125.27 mg/100g to 185.58 mg/100g of calcium, 32.27 to 55.58 mg/100g of magnesium, 62.26 mg/100g to 120.25 mg/100g of sodium and 266.66 mg/100g to 374.12 mg/100g of potassium. The "energy" snack bars were acceptable with desirable sensory quality by all consumers. It was observed that while the addition of cassava flour and cashew kernel flour improved ratings for the energy bars, the addition of toasted bambara groundnut flour had the opposite effect.

“…Yuen and Kelly (310) decomposed vegetable oil for phosphorus determination by heating in a Parr bomb containing 2 mL of H20 and filled with oxygen to 25 atm. Wet digestion in an open vessel remains the most common technique; improvements in the digestion media (311)(312)(313), automation (314), and use of a glassy-carbon container (315) were described.…”

This article is a continuation of the previous review (2) and covers the literature from October 1979 to September 1981. An exceptionally large number of research papers were published during this period. As has been mentioned before, the trend is to develop methods for organic elemental analysis at all levels (2). Whereas many studies have been carried out in the determination of the major constituents in organic compounds, reliable automated methods of general applicability are still limited to carbon, hydrogen, and nitrogen. Much attention has been drawn toward trace analysis, particularly for toxic elements present in all kinds of organic materials.
