[ technical field ] A method for producing a semiconductor device

The invention relates to a lactobacillus fermented beverage, and in particular relates to a calcium-supplementing lactobacillus fermented beverage for pets and a preparation method thereof.

[ background of the invention ]

More and more people are raising pets in modern society, and pets have become part of the lives of most people, and most pets are particularly cat dogs. Because the gastrointestinal functions of pets, particularly cats and dogs are not good, the pets are difficult to completely absorb calcium in foods, and phenomena of calcium deficiency, such as muscle weakness, poor limb strength and the like, are often caused. In order to avoid symptoms such as abdominal distension, exsufflation or diarrhea when the pet is young or weak and sick, the artificial feeding of the milk beverage is more needed.

At present, the calcium-supplementing milk beverage for pets on the market is single, and particularly, the calcium-supplementing milk beverage for pets after being fermented by lactic acid bacteria is less. Lactic acid bacteria are a probiotic that is widely distributed in nature, and are named for their ability to ferment carbohydrates into lactic acid. The lactobacillus can improve the nutritive value of the pet food, improve the flavor of the pet food and improve the quality preservation and added value of the pet food in a fermentation mode, and in addition, the unique physiological activity and the nutritional function of the lactobacillus can also directly improve the intestinal flora of the pet, regulate the microbial balance, reduce the pH of the intestinal tract, inhibit the growth of harmful bacteria, stimulate the gastrointestinal peristalsis, generate B vitamins, enhance the intestinal motility, help digestion and absorption and improve the immunocompetence.

However, the sense of smell of pets, especially cats and dogs, is often stronger than that of human beings, and the habits of different pets are greatly different, so that the preference of the pets for food is different, and the preference of the pets for milk beverages is biased, so that the existing pet milk beverage is difficult to be suitable for the differentiated pet market, and the milk beverage fermented by lactic acid bacteria is difficult to be accepted by the pets and difficult to popularize due to the sour taste.

Therefore, according to the habit characteristics of different pets, the development of a common calcium-supplementing lactobacillus fermented beverage for pets is very necessary for the commercial pet market.

[ summary of the invention ]

The invention aims to overcome the defects of the prior art and provide the calcium supplementing lactobacillus fermented beverage for the pet, which has the advantages of moderate viscosity, good taste masking property, calcium supplementing effect and the like, and is wide in raw material source range, low in cost and suitable for large-scale production.

The technical scheme of the invention is explained in detail as follows:

the calcium-supplementing lactobacillus fermented beverage for the pets is prepared from a dairy product, water, lactobacillus, a sweetening agent, a thickening agent, a taste-masking agent, a preservative and a stabilizing agent.

The milk product mainly adopts milk powder, preferably whole or semi-skimmed milk powder, and some cream is added in an auxiliary way when the skimmed milk powder is adopted, so that the fat content of the lactic acid bacteria emulsion is increased, and the nutritional value of the pet milk beverage is increased.

The water of the invention is preferably purified water, especially purified water with a conductivity of less than 10 mu, mainly to avoid the incorporation of impurities, in particular heavy metals harmful to the pet body.

The active content of the lactic acid bacteria is 100 ten thousand units, and the lactic acid bacteria can be commercially available.

The sweetening agent is cane sugar or the mixture ratio of cane sugar and sucralose, and the sweetness of the sucralose is 400-800 times that of the cane sugar, so the cost can be saved by adopting the mixture ratio of the cane sugar and the sucralose under the same sweetness. Adjusting to basic sweetness with sucralose, and supplementing sucrose to proper sweetness.

The thickening agent is a mixture of sodium carboxymethylcellulose and hydroxypropyl methylcellulose, so that the milk beverage can be gelatinized, the fluidity is reduced, the milk beverage can be hung or remained in the oral cavity after being eaten by pets, the milk flavor can be kept in the oral cavity for a period of time, the hydroxypropyl methylcellulose also plays a role of a suspending agent, the chitin powder is ensured not to precipitate and is uniformly distributed in the milk beverage, and meanwhile, the hydroxypropyl methylcellulose is also synergistically compounded with the chitin powder to play a role in covering the flavor. In order to ensure the effect of uniform distribution of the chitin powder and control the cost, the hydroxypropyl methyl cellulose is preferably in the range of 1-5 parts.

The taste masking agent is chitin powder, in particular to oyster shell powder, and the oyster shell powder is superfine crushed oyster shell powder with the specification of more than 250 meshes. The oyster shell powder is selected, on one hand, the olfactory habits and the food preference of different pets are considered, on the other hand, the calcium supplement is realized, the oyster shell powder particles and lactic acid generated after the fermentation of lactic acid bacteria can react to generate partial calcium lactate to reduce the acidity of the milk beverage, the specific surface area of the superfine crushed oyster shell powder is large, a plurality of pores are formed among calcium molecules, and meanwhile, partial lactic acid can be adsorbed to cover the acidity.

According to the invention, the preservative potassium sorbate is added to prolong the shelf life of the milk beverage and prevent the milk beverage from deteriorating in the shelf life.

The invention adds stabilizer pectin which is mainly used as an auxiliary additive to assist thickening so as to improve the mouthfeel. And simultaneously, the product is ensured not to generate precipitation or delamination in the shelf life.

The preferable mixture ratio combination of the invention is as follows: 10-150 parts of milk powder, 850-990 parts of purified water, 0.1-0.5 part of lactic acid bacteria, 5-10 parts of cane sugar, 1-5 parts of sodium carboxymethylcellulose, 1-5 parts of hydroxypropyl methylcellulose, 1-10 parts of superfine crushed oyster shell powder, 0.1-0.5 part of potassium sorbate and 1-10 parts of pectin.

The preferable proportioning combination of the invention can also be as follows: 10-150 parts of milk powder, 850-990 parts of purified water, 0.1-0.5 part of lactic acid bacteria, 1-5 parts of sucrose, 0.01-0.05 part of sucralose, 1-5 parts of sodium carboxymethylcellulose, 1-5 parts of hydroxypropyl methylcellulose, 1-10 parts of superfine crushed oyster shell powder, 0.1-0.5 part of potassium sorbate and 1-10 parts of pectin.

The preferable proportioning combination of the invention can also be as follows: 9-150 parts of milk powder, 1 part of cream, 850-990 parts of purified water, 0.1-0.5 part of lactic acid bacteria, 5-10 parts of cane sugar, 1-5 parts of sodium carboxymethylcellulose, 1-5 parts of hydroxypropyl methyl cellulose, 1-10 parts of superfine crushed oyster shell powder, 0.1-0.5 part of potassium sorbate and 1-10 parts of pectin.
