Process for preparing water-retaining agent used for edible mushroom cultivation fungus sticks

Abstract

A process for preparing water-retaining agent used for edible mushroom cultivation fungus sticks belongs to the field of agricultural materials. The water-retaining agent is formed by utilizing wax, resin and oil as main components and utilizing white carbon black and / or carbon black and the like as filling materials, and weight proportion of the water-retaining agent includes that the wax takes 15%-70%, the resin takes 10%-60%, the oil takes 1%-20% and the filling materials take 0.1%-5%. The oil and the wax in the ingredient perform congruent melting, the resin is added after the wax is completely melted basically, or the oil, the wax and the resin in the ingredient perform congruent melted at temperature of 100-120 DEG C, are added with the filling materials after the resin is melted completely and then is cooled and shaped to obtain the water-retaining agent. The water-retaining agent is nontoxic, can be safely used for cultivating food materials, is excellent in water-retaining property, and has fine water-retaining property which is more excellent than paraffin wax used as water-retaining agent by 30%-80%, and coating of the water-retaining agent in a melting state can be dried fast, thereby bringing convenience for farmers. In addition, the water-retaining agent has certain elasticity and plasticity, can be freely expandable along with moisturizing and evaporation of the fungus sticks, and is favorable for growth of mushrooms with normal and attractive mushroom shapes. Moreover, after being added with the filling materials, the water-retaining property of the water-retaining agent can be improved, and then the water-retaining agent has a function of identifying appearances of products.

Description

technical field [0001] The invention discloses a method for preparing a water-retaining agent used for cultivating edible fungus sticks. The water-retaining agent is a material for preventing dehydration for cultivating edible fungi with unique functions, and the material is prepared from relevant food additives that are safe for use in food. It belongs to the field of agricultural materials. Background technique [0002] Since 1980, the cultivation of edible fungi in my country has created a history of artificial mass cultivation of "mushroom sticks". Pressed into a rod shape with a diameter of 10 cm and a length of about 40 cm, put it into a specific plastic bag, and then undergo cooking, heating, cooling and aging, inoculation and other processes. Generally, the average temperature is below 25°C (usually from November to the next year) May) mushrooms can be grown in stages. But its core problem is the water retention performance of the fungus stick after removing the plas...

Problems solved by technology

[0004] The film-forming water retention method has been adopted by a large number of farmers, but due to management difficulties, a large number of farmers directly buy cheaper industrial wax from vendors to apply bacteria sticks. As we all know, industrial wax contains a certain amount of condensed aromatic hydrocarbons. Strong carcinogens, used for dipping mushroom sticks, will inevitably be absorbed by mushrooms and cause endless harm
