example 1

[0015] Example 1: Accurately weigh 76g lactose, 1.2g polyethylene glycol, 2.2g anhydrous sodium bicarbonate, 0.6g N-naphthalene ethylenediamine hydrochloride, 1.0g p-aminobenzenesulfonic acid, 20.0g sulfamic acid, and grind Mix evenly in the machine, then wet with 4% polyvinylpyrrolidone ethanol solution, granulate, pass through a 50-mesh sieve, and vacuum-dry at 50°C for 30-60min, then press the mixed reagent under low pressure (4-8MPa) to form Small discs with a weight of 100mg and a diameter of 10mm. The tablet can be guaranteed for more than 2 years at room temperature in a sealed and dry environment.

example 2

[0016] Example 2: Accurately weigh 72g lactose, 1.0g polyethylene glycol, 3.3g anhydrous sodium bicarbonate, 1.8g N-naphthalene ethylenediamine hydrochloride, 3.0g p-aminobenzenesulfonic acid, 16.0g sulfamic acid, and grind Mix evenly in the machine, then wet with 4% polyvinylpyrrolidone ethanol solution, granulate, pass through a 50-mesh sieve, and vacuum-dry at 50°C for 30-60min, then press the mixed reagent under low pressure (4-8MPa) to form Small discs with a weight of 100mg and a diameter of 10mm. The tablet can be guaranteed for more than 2 years at room temperature in a sealed and dry environment.

Abstract

The invention discloses an effervescent tablet capable of fast detecting nitrite in food, relating to the field of safety and fast food detection and aiming at solving the problems that the commonly-used method for detecting nitrite is complicated in steps and required for instrument and equipment and real-time fast detection can not be carried out on site, the fast detection kit of existing-form nitrite is inconvenient to operate, easily-deteriorated in transportation and storage or usage process, and the like. The tablet for detection comprises ingredients in percentage by weight: 1.4%-5% of detection agent, 16.5%-18.2% of acid agent, 69.1%-74% of filling agent, 1%-1.1% of lubricating agent, and 2.2%-3.4% of effervescing agent. The effervescent tablet can be directly applied to fast semi-quantitative or qualitative detection of nitrite in a food extracting solution, is simple and convenient to operate, can be fast dissolved and react with nitrite to produce colored matters convenient to visually observe, not easy to deteriorate in the transportation and storage and usage processes, easy to store, long in shelf life, low in production cost and capable of carrying out scale production.

Description

technical field [0001] The invention relates to the field of rapid detection of food safety, in particular to the rapid detection of nitrite in food. Background technique [0002] Nitrite is a general term for a class of inorganic compounds, mainly referring to sodium nitrite, which is white to light yellow powder or granular, slightly salty in taste, and easily soluble in water. Because nitrite has a good antibacterial effect, it can prevent the growth of Clostridium botulinum in meat products, thereby preventing food poisoning caused by Clostridium botulinum producing botulinum toxin, and improving the safety of meat products; At the same time, it can be used as a coloring agent for meat products, combining with myoglobin in meat products to form a more stable bright red substance, making meat products appear attractive bright red and increasing consumers' desire to buy. It is an important food additive for food products. However, nitrite is a highly toxic substance, and...
