Abstract
The invention discloses a method for determining the content of iron powder in a pepper product rapidly. The method comprises the following steps of: 1) configuring a liquid; 2) taking iron; and 3) drying and weighing. The method for determining the content of the iron powder in the pepper product rapidly is used for determining the content of the iron powder in the pepper product, has the obvious characteristics of convenience, rapidity and accuracy, is especially suitable for continuous production line determination, and has good positive significance for guiding production.
Description
Technical field
The invention belongs to food processing field, be specifically related to the method for iron content in a kind of Fast Measurement chilli products.
Background technology
Owing to the wearing and tearing meeting generating portion iron powder of machine, although added in process of production degaussing equipment, iron content exceeds standard sometimes in process of production for chilli powder and chilli products thereof, therefore needs in process of production the iron content in the regular testing product.
At present in the industry except GB detects, the employing optical method that has, the employing curve method that has detects the iron content in the chilli products, but, no matter any detection method, have all that error at measurment is large, the mensuration process is complicated, the problem that cost of determination is high.
Summary of the invention
The object of the present invention is to provide the method for iron content in a kind of Fast Measurement chilli products, can measure rapidly and accurately iron content in the chilli products by the method, instruct the workshop to produce.
In order to realize the present invention, the method for iron content in a kind of Fast Measurement chilli products of the present invention, the technical scheme of taking is as follows:
The method of iron content in a kind of Fast Measurement chilli products, it may further comprise the steps:
1) configuration liquid: take by weighing first the powdery chilli products or the semisolid chilli products is put into bucket, add the distilled water configuration liquid that stirs, wherein powdery chilli products and distilled water are in the ratio of 300g: 2-3L, and semisolid chilli products and distilled water are in the ratio of 500g: 7-8L;
2) get iron: with step 1) configuration liquid stir more than 7 minutes with the same direction of the bar magnet of 10,000 GS after, take out bar magnet and wash down chilli products on the bar magnet with distilled water, iron powder is collected together, with paper clip iron powder is transferred on the slide again;
3) oven dry is weighed: with step 2) slide place 120 ℃ of baking ovens bakings 30 minutes to constant weight, then taking out slide with tweezers weighs with analytical balance, first-selection takes by weighing slide and iron powder general assembly (TW), then takes by weighing iron powder weight, then adopts following formula to calculate iron content:
Computing formula: iron content (ppm)=W
1+ W
0/ W * 10
6
In the formula: W
1-slide and iron powder weight, g
W
0-iron powder weight, g
The W-sample mass, g.
The method of iron content in a kind of Fast Measurement chilli products of the present invention, described chilli products is powdery or semisolid chilli products.
The present patent application people has done effective experiment, test, and wherein will to reach at least the data of measuring more than 7 minutes the most stable bar magnet time of stirring:
The testing result table of different bar magnet mixing time iron contents
The method of iron content has convenient, fast and accurate notable feature in a kind of Fast Measurement chilli products of the present invention, is particularly suitable for the production line METHOD FOR CONTINUOUS DETERMINATION, has very positive meaning to instructing to produce.
Embodiment
The present invention is further elaborated below in conjunction with embodiment.Need to prove that present embodiment is not limited to the concrete sampling amount of chilli products.

2) get iron: with step 1) configuration liquid stir more than 7 minutes with the same direction of the bar magnet of 10,000 GS after, take out bar magnet and wash down chilli products on the bar magnet with distilled water, iron powder is collected together, with paper clip iron powder is transferred on the slide again;
3) oven dry is weighed: with step 2) slide place 120 ℃ of baking ovens bakings 30 minutes to constant weight, then taking out slide with tweezers weighs with analytical balance, first-selection takes by weighing slide and iron powder general assembly (TW), then takes by weighing iron powder weight, then adopts following formula to calculate iron content:
Computing formula: iron content (ppm)=W
1+ W
0/ W * 10
6
In the formula: W
1-slide and iron powder weight, g
W
0-iron powder weight, g
The W-sample mass, g
Can draw iron content.
The method of iron content in a kind of Fast Measurement chilli products of the present invention, the mensuration for the chilli products iron content has convenient, fast and accurate notable feature, is particularly suitable for the production line METHOD FOR CONTINUOUS DETERMINATION, has very positive meaning to instructing to produce.
