RESUMO
The aim of this study was to develop alternative formulas for elderly enteral feeding using conventional foods from food staples distributed in the city of Piracicaba-SP. The foods used in the formulas were: corn meal, soya oil, rice, beans, pasta, sardine, powder milk, corn starch, eggs, texturized soya protein, cabbage, and carrot. Physical analyses (dripping and viscosity), chemical analyses (centesimal composition, protein digestibility, iron determination, iron dialyses in vitro, -carotene determination, anti-nutritional factors - tannins and phytate), microbiological analyses (Salmonella, Bacillus cereus, positive Staphylococcus coagulase and total Coliforms), cost analyses and elaboration of a manual for good manipulation practices were carried out. Results were analyzed statistically using Tukey test, SAS software (1996) and for regression using Microsoft Office Excel (2003). Liquid formulas presented better nutritional, physical and microbiological results as well as economical viability Therefore were suggested for elderly enteral nourishment. According to the elderly clinical needs, two alternatives are suggested among liquid formulas. The F3 formula is noticeable for iron availability, quantity of -carotene, digestibility, dripping and viscosity. The F4 formulas is noticeable for the total calorie distribution of macronutrients as well as for having a higher number of calories and good viscosity and dripping which is ideal for the elderly, according to international recommendations. The formulas presented a range of 131 to 216 calories/250ml. Liquid formulas presented higher number of calories than powder formulas. The formulas contributed with a 20% adequacy regarding to macronutrient recommendations for the elderly from DRI (2002), when two servings of 250mL.day-1 (powder or liquid) were ingested.
