Background
In recent years, with the improvement of living standard of people and the change of consumption and infant care concept, the occupation of infant supplementary food in the infant food market is increasingly prominent, and the infant supplementary food is supplementary food except breast milk, can supplement and perfect nutrients required to be taken by the growth and development of infants, and promotes the healthy growth of the infants. Among numerous complementary foods, the infant fruit puree is a preferred product for many families when being added with complementary foods for babies, and has the characteristics of abundant nutrition, mellow fruit flavor, fine and smooth mouthfeel, direct swallowing without chewing and the like in a pasty fluid form. The infant fruit puree is a fruit processing product specially designed for infants (more than 6 months), and can supplement fruit nutrition gaps of the infants. In order to meet different tastes and nutritional requirements of babies, fruit paste products produced by matching different fruits and other raw and auxiliary materials appear in a competitive way on the market, the taste and the variety of the fruit paste are greatly enriched, and the selection of consumers is increased.
At present, the market of the fruit puree is mainly of foreign brands, the market share of the domestic fruit puree is relatively low, parents have high attention to the safety of the fruit puree when the parents purchase the fruit puree for babies, and therefore the organic and purely natural fruit puree is more favored by mothers. However, whether the fruit puree is of a foreign brand or a domestic brand, whether the fruit puree is organic fruit puree or common fruit puree, the fruit puree has high sugar content and high sweetness due to the use of fruit raw materials, the mouthfeel of some products is too sweet and greasy, high-sugar diet can cause various health hazards to infants, such as decayed teeth, picky food, monophagia, dysplasia, obesity, myopia and the like, and the World Health Organization (WHO) strongly recommends that the addition of sugar to the food for infants below 3 years old is forbidden, and the daily sugar intake of the infants is strictly controlled. However, under the condition of no sugar, the content of soluble solid in the infant fruit paste in the current market is also between 13% and 15%, even as high as about 20%, the sugar content is relatively high, the sweet taste is strong, and the healthy growth of infants can be influenced by long-term or excessive eating.
In addition, the apple pulp dregs generated by producing apple juice every year in China are more than 100 million tons, and most of the pulp dregs are treated as wastes, so that the effective utilization rate is low, resources are wasted, the corresponding economic benefit cannot be obtained, and the environmental pollution can be caused. According to preliminary determination, the pulp residues have the characteristics of high dietary cellulose content, small dietary fiber molecules, rich mineral substances, low sugar content and the like, and have high nutritional and edible values.
Therefore, how to utilize the fruit resources of China to a greater extent and produce the pure natural infant blood sugar reducing fruit paste with high additional value is an urgent problem to be solved in the fruit paste production industry. At present, no report about sugar-reducing fruit paste is found in reports about fruit paste preparation.
Disclosure of Invention
The invention aims to provide pure natural apple and white peach blood glucose reducing infant fruit paste and a preparation method thereof, and aims to solve the problems in the background art.
The pure natural infant blood sugar-reducing fruit paste is provided, wherein the sugar content of the fruit paste is 30% -60% lower than that of the infant fruit paste sold in the market, the dietary fiber content of the fruit paste is higher than that of the infant fruit paste sold in the market, the taste is milder, and the pure natural infant blood sugar-reducing fruit paste is more suitable for infants to eat.
The key point of the method is that apple pulp residue with low sugar content is used as one of raw materials to prepare low-sugar apple fiber which is applied to the preparation of the fruit paste, so that the integral sweetness and the total sugar content of the fruit paste are reduced. The apple fiber has low sugar content, is rich in dietary fiber and mineral with low molecular weight, can promote intestinal tract movement, relieve constipation, and has high nutritive function and edible value.
