Preparation method of nutritional rice cake for infants
[ technical field ] A method for producing a semiconductor device
The invention relates to the field of rice cake making, and particularly relates to a preparation method of a nutritional rice cake for infants.
[ background of the invention ]
Infants, typically between 1 and 3 years of age, have a slower rate of growth in length and weight than infants under 1 year of age. After the age of 1 year, the weight of the infant is increased by about 2 kilograms per year until the school age. Usually, the weight of children before the age of 3 years is increased more. Thus, infants require a lot of energy and abundant nutrients during growth.
Rice cake is traditional food of Chinese nation's nation, and the development has had a long history for hundreds of years to date, and in the time of the festival, every family household is the sound of rice cake hammer beating cake, and hearing cake hammer just means the emergence of happy events. The rice cake is a good product for serving relatives and friends and visiting friends. The rice cake is refined by using high-quality rice, selected peanuts as main raw materials and salt and sugar as auxiliary materials. The crisp sausage is popular with consumers by the characteristics of thin wrapper, more stuffing, crisp and delicious taste, moderate saltiness, faint scent and pleasant taste, and suitability for both the old and the young.
Along with the development of economy and the improvement of living standard, consumers pay more and more attention to health, and especially have higher and more requirements on infant food, although the rice cake has the advantages of natural materials and good taste, the rice cake has few and incomplete tastes and nutrition and cannot provide comprehensive and balanced nutrition for infants, so that the research on the infant nutritional rice cake with complete nutrition has wide market popularization value.
