Problems solved by technology

The existing grain steam tableting technology mainly increases the gelatinization degree of grain starch by prolonging the cooking time. However, due to the limitation of the water permeability of the grain surface, the existing technology cannot effectively realize the gelatinization of grain starch, which will improve the nutritional value of grain. limited

Embodiment 1

[0016] Example 1: 1 control group and 3 treatment groups, the control group is common steam-flaked corn, and the treatment group is steam-flaked corn with propylene glycol added to the corn to be steam-flaked, and the addition amounts are 0.1%, 0.4%, respectively. %, 1.0%. The nutritional components of the steam-flaked corn in the control group and three treatment groups were determined (Table 1).

[0017]

Embodiment 2

[0018] Example 2: 1 control group and 3 treatment groups, the control group is common steam-flaked corn, and the treatment group is steam-flaked corn with ammonium propionate added to the corn to be steam-flaked, and the addition amount is 2% respectively , 5%, 8%. The nutritional components of the steam-flaked corn in the control group and three treatment groups were determined respectively (Table 2).

Embodiment 3

[0020] Embodiment three: 1 control group and 3 treatment groups, the control group is common steam-flaked corn, and the treatment group is the steam-flaked corn that has added propylene glycol and ammonium propionate to the corn to be steam-flaked simultaneously, and the addition amount is : Treatment A: 0.15% propylene glycol, 2% ammonium propionate; Treatment B: 0.25% propylene glycol, 3% ammonium propionate; Treatment 3: 0.4% propylene glycol, 5% ammonium propionate. The nutritional components of the steam-flaked corn in the control group and three treatment groups were determined respectively (Table 3).

Abstract

The present invention discloses grain treating method before steam tabletting. The technological scheme of the present invention is that propylene glycol and / or ammonium propionate are added into grain before steam tabletting. The grain treating method before steam tabletting can raise the starch dextrinization degree and coarse protein content of tabletted grain, prevent molding of grain, raise the bioavailability of tabletted grain and improve the animal producing performance of tabletted grain.

Description

technical field [0001] The invention relates to a preparation method for pretreatment of grain steam tableting. The grain processed by the method has better water permeability, which can improve the degree of gelatinization of the grain in the tableting process, and can also prevent the preservation of the steam-pressed grain Mildew reaction in the process. The invention belongs to the technical field of feed processing. Background technique [0002] The steam flaking technology of grains has been widely used at home and abroad. In this technology, the corn to be tempered is placed in the cooking tank, and the corn is expanded and softened by steam heat processing, so that the corn starch is fully gelatinized, and then the corn is rolled by a pair of rollers. The mechanical pressure generated by a pair of counter-rotating rollers of the flaking machine peels and cracks the expanded grains, so that the grains are processed into flakes with a specified density, and finally th...
