The present invention relates to a substance state simple discriminator, and more particularly, to provide a substance state (milk state) simple discriminator capable of simply measuring the state of milk.

In general, milk is a food rich in nutrients enough to be known as a complete food, but is also a food that is prone to rancidity due to easy generation and reproduction of bacteria due to the many nutrients.

The milk is squeezed from the cow to the state to be consumed by the consumer, that is, collect milk from the cow in the ranch, transport the milk from the cow to the processing plant, the milk to the consumer to drink at the processing plant The process of commercializing, distributing milk commercialized in the processing plant to a distributor, and delivering it to a store or home from the agency takes place in a completely refrigerated state called a cold chain system.

When the cold chain is broken or a problem occurs in the distribution process, the milk is often deteriorated even in the product within the distribution period.

However, since consumers have determined whether the milk is deteriorated by sensory tests, which mainly depend on smell and taste, there is a problem that if the quality of milk is small, it is not able to identify the deterioration when the taste or smell of the consumer is not sensitive. .

In addition, in the case of milk (hereinafter referred to as "processed milk") with unique flavors and flavors such as chocolate milk, strawberry milk, banana milk, etc., there was a problem that it is more difficult to determine whether the quality is changed by taste and smell.

In addition, milk that is within the shelf life, but milk squeezed with diseased milk, colostrum, lactation period, the ratio of phosphate or citric acid to calcium or magnesium is not normal, so-called milk or bacteria with poor ash equilibrium. Milk produced in case of abnormal casein due to blood lineage or physiological modulation, or mastitis oil of grade 5 or higher determined by the livestock counting method was impossible for ordinary consumers to identify.

In addition, even if the shelf life of milk is passed, even if the milk is well stored, the general consumer can not determine the state of milk accurately, there was a problem that discarded milk.

The present invention has been proposed in view of the above problems, and an object of the present invention is to provide a simple substance state discriminator which can easily determine the state of milk.
