Description
Technical field
The invention belongs to analyzer fields, and in particular to be a kind of portable breast milk analyser.
Background technology
Breast milk is most natural, most safe, the most complete natural food of baby development, it contains all needed for baby development
Nutrition and antibody, especially breast milk contain 50 percent fat, other than supplying baby's body heat, also meet baby
Fat needed for brain development (structure of brain 60% comes from fat)；Abundant calcium and phosphorus can make baby grow it is not only high but also
It is strong；Immunoglobulin can effectively prevent and protect baby from infection and the generation of chronic disease；Than have to the factor and oligosaccharides can
To inhibit enteron aisle germ hyperplasia and help digest.In addition to this, the intimate contact and parent child relationship for feeding breast milk can stimulate baby
Brain and intelligence development；For breast milk compared with formula milk, the infant of breast-feeding can more effectively utilize the nutrition in breast milk
Substance is not easy to suffer from various infectious diseases, keeps normal growth and development, be primarily due in breast milk containing lactoferrin,
The various actives albumen such as immunoglobulin and lysozyme can promote the digestion of nutritional ingredient, absorb, and protect body from micro- life
Object infects.Wherein lactoferrin is anti-in immunity of organism also by promoting the normal development of gastrointestinal tract, especially mucosal immune system
Epidemic disease system aspects play an important role, and lactoferrin is added in milk powder closer to breast milk, to strengthen these immune factor energy
Increase its immune function.
Neonatal immune system is about about one year old just to reach maturity, so the bigger children of their anti-infection ability
It is weak with being grown up, it is easy to happen intestines problem, keeps nutrition intake impacted, and then influences growth level.Lactoferrin is female
The natural component of rich content in breast accounts for about the 20% of human milk total protein, at least two aspect of nutritive value：First, as ammonia
The dietary proteins source of base acid；Second is that being conducive to the biological utilisation of iron.But not every babies ' formula milk powder all contains lactoferrin,
Therefore strengthening lactoferrin in babies ' formula milk powder makes nutritional ingredient close to breast milk, and the nutritional need and growth to natus are sent out
It educates of crucial importance, intestinal beneficial bacterium can be promoted to grow, help infant to resist Escherichia coli, reduce the microorganisms such as virus and cause
Babies' common disease such as diarrhea, enteritis, constructed the first line of defence of life.Oral lactoferrin is safe and reliable, without any
Side effect.Therefore, by lactoferrin it is effective and reasonable be applied to common baby formula milk powder in, can both meet infant physical growth hair
The needs educated, while playing a protective role again to the health of baby, it is particularly important to the needs of non-breastfeeding infant nutrient.
The main reason for some mothers abandon feeding breast milk has respectively：Lack milk, worry that baby does not have enough to eat or not enough seeks
It supports, pain is sucked or felt when sucking to baby's refusal, be short of physical strength, nipple is ached or broken skin, mammary swelling pain, not side of going to work
The factors such as just；So the powder that can only breast-feed to baby, milk powder is by manufactured powder after milk removing moisture content, it is suitable for preservation.Milk
Powder is, with the method for freezing or heating, to remove most moisture in breast using fresh milk or goat milk as raw material, add after dry
The reconstituted food for adding suitable vitamin, minerals etc. to be process, milk powder is easy to reconstitute, be convenient for carrying, full of nutrition.It is instant
Milk powder is bigger and loose than ordinary powdered milk particle, and wettability is good, and dispersion degree is high.When reconstituting, that is, use warm water that can also dissolve rapidly.Milk
Powder is that mammal fresh milk is removed manufactured powder after moisture, it is and easy to carry suitable for preserving.
And after Sanlu milk powder case, people have prodigious worry to the safety of milk powder, so often right
Milk powder carries out Concentration Testing, or even due to own bodies health, can be equally detected to breast milk, but existing breast milk
The detection of concentration can only go to hospital to be detected, and the detection device of hospital is larger, and expensive, not be that average family can
It affords, and inconvenient to carry, and the detection cycle of breast milk concentration detector used in hospital is longer.
