Multigrain meal replacement powder formula design based on linear programming for the elderly
Currently,aging has become a topic of widespread concern.With the increase of age,the prevalence of chronic diseases in the elderly also in creases.Multigrain is a kind of high-quality food with both dietary and therapeutic function,which can effectively prevent the occurrence of some chronic diseases in the elderly.Meal replacement powder is convenient to eat,easy to digest and absorb.Therefore,it is of great significance to develop a kind of multigrain meal replacement powder with balanced nutrition for the elderly population in this study.The formula of multigrain meal replacement powder for the elderly population was designed with millet,soybean and barley as the main raw materials,and with oats,purple potato,buckwheat and bran as the supplemented.The formula design was based on linear programming,with the adequate intake(AI)of human dietary nutrients as the main constraint condition and fuzzy mathematical sensory score as the index.The optimal formula was millet 101.50 g,soybean 104.46 g,barley 100.61 g,oats 10.00 g,purple potato 9.00 g,buckwheat 8.00 g and bran 7.00 g,with nutrient fortifying agent VB2 0.01 mg,Vc 33.30 mg,calcium carbonate 54.93 mg,sodium chloride 1 148.86 mg and selenium-rich yeast 9.56 mg.It was found that the multigrain meal replacement powder prepared according to the above formula was of uniform color,excellent flavor and taste,good blending ability,and balanced nutrition.Moreover,the powder was formulated,which meets the requirements of high protein,and easy digestion and absorption in the diet of the elderly.It is expected to provide basic data and some benefit references for the development of new meal replacement powder and food for the aged.
