Instruction of Le Jiao Yeast Promoter

I. Product Introduction

Le Jiao yeast promoter (protease) is a compound nutritional preparation prepared by adopting excellent strains through liquid submerged fermentation, extraction and refining, and compounding to promote the yeast growing factors. It is a new yeast promoter specially designed to improve yeast fission performance, environmental tolerance performance and sugar alcohol conversion performance, so as to shorten fermentation period, reduce residual sugar value of mature mash, increase alcohol yield and enhance the utilization rate of raw materials.

Safe and non-toxic as well as convenient to use, Le Jiao yeast promoter (complex enzyme) can partially (or completely) replace urea and other nutrients in the traditional process. In particular, remarkable effect can be achieved in high concentration mash fermentation process.

II. Applicable raw materials

It is suitable for enterprises that use starch and molasses as raw materials to produce alcohol.

III. Recommended dosage

According to the mass of raw materials, molasses can be added based on 100g-200g/ton of raw materials and corn is added based on 150g-200g/ton of raw materials.

Ⅵ. Product Specification

Ⅶ. Function

1. Increase the number of yeast cells and the rate of germination, accelerate the fermentation, and shorten the fermentation cycle .

2. Yeast transformed sugar alcohol to improve the ability to improve the fermentation liquor end parts, reduce the production cost.

3. Reduce the residual sugars and eutrophic substance precursor material to reduce the vinasse drying process Maillard reaction, reducing the pressure on sewagetreatment.

Ⅷ. Product uniqueness

1. It completely replaces nutrient salts such as urea and ammonium sulfate on molasses alcohol, and partially replaces urea and ammonium sulfate on corn alcohol.

2. Balance alcohol yeast nutrition (increasing cell number and germination rate ), adjust yeast osmotic pressure (osmotic pressure determines sugar consumption) , improve yeast high alcohol tolerance (lower sugar) and improve alcohol content .

3. The alcohol can be increased 0.6- 2.0% (v / v) when used in Molasses alcohol ; and the alcohol can be increased 0.3 ~ 0.6% (v / v ) when used in corn alcohol .

Ⅸ. Application method

When culturing distiller’s yeast, take a corresponding amount of promoter based on the weight of raw materials and then add it directly into the tank of distiller’s yeast; yeast promoter required for the subsequent feeding of the fermentation tank is added in the distiller’s yeast tank by the way of flowing, directly brought into the fermentation tank by distiller’s yeast mash or directly added into the fermentation tank.

Ⅹ. Safety and Handling Precautions

Enzyme preparations are proteins, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.

Ⅺ. Dosage form, package specification, storage and expiration date
