Abstract

FIELD: feed production. The purpose of the invention in-. Increases shelf life and improves the quality of grass meal. A method for stabilizing carotene in grass meal involves the introduction of an antioxidant into it, which is based on a mixture of bentonite clay and flour from the vegetative waste of a tea plant in a ratio of 0.95-1.05: 4.5-5.5. This mixture is added to grass flour in a ratio of 0.95-1.05: 9.5-10.5. After 180 days of storage, the carotene content in the control batches of grass meal (without antioxidant) decreased from 250 to 50 mg / kg, and in the experimental one (with the proposed antioxidant) to 190 mg / kg. 1 tab.

FIELD: feed production.

The purpose of the invention is to increase the shelf life and improve the quality of grass meal.

Example 1. 30, O kg of bentonite clay is mixed with 150 kg of flour from vegetative waste of a tea bush (in a ratio of 0.35-1.05: 4.5-5.5) for 3 minutes in a batch mixer.

This mixture is introduced into grass flour in a ratio of 0.95-1.05: 9.5-10.5 (90 kg of a mixture of bentonite clay and 900 kg of flour from vegetative waste of a tea-plant).

The resulting stabilized grass meal is packaged in paper Kraft bags and stored for storage.

In studies, bentonite clay of the following composition is used,%: SiO 50.96-56.94; TiO 0.31-0.42; AljO, 16.15-16.35; 2.57-6.73; FeO 0.12; MgO 0.95-2, jy; CaO 1.36-3.78; Na.2.0 0.14-1.94; 1.05-1.06; SO, 0.06-0.5; moisture 9.15-11.46 and flour from the vegetative # 1x waste of the tea-tree of the following chemical composition: carotene 150 mg / kg; crude protein 18%; cheese fiber 25%; caffeine 3%; tannin 5%.

On the basis of the research conducted, the optimal ratios of bentonite and waste of the tea-bush were selected. The best parties are those with the best flowability. When the ratio of bentonite clay and flour from the vegetative waste of the tea bush is 1: 4, the flowability of the mixture is 5 points.

at a ratio of 1: 5 10 points, at a ratio of 1: 6 8 points. As can be seen, the best flowability of bentonite and flour from tea tree waste is provided at a ratio of 1: 5.

Similarly, the optimal ratio of the mixture with grass flour (1:10) is selected. However, in this case, the criterion is the safety of carotene in grass meal.

The table lists the changes in the quality indicators of grass meal during storage with the introduction of a mixture of bentonite clay and flour from the vegetative waste of the tea bush and without it.

After 180 days of storage in batches of grass meal with bentonite clay and flour from vegetative waste of the tea plant, the content of carotene decreased from 250 to 190 mg / kg; in the control batches, the content of carotene during storage was reduced to 50,

70 mg / kg.
