Description

Whipped cream and method for producing the same

The present invention relates to whipped cream and a method for producing the same, and more particularly to a whipped cream that can be distributed at room temperature and a method for producing the same.

Whipped cream is widely used as a filling material in bakery products such as bread and confectionery, and in foods such as baked goods such as pudding and mousse. The whipped cream includes a water-in-oil type cream (so-called butter cream) and an oil-in-water type cream. Water-in-oil type creams have been widely used in ordinary temperature distribution foods such as bread and confectionery because of their good stability at normal temperatures. However, the water-in-oil type cream has a problem in that the use of fats and oils with a high melting point deteriorates mouth melting.

In recent years, with the trend toward high-end markets and the development of distribution networks, even ordinary-temperature distribution-type foods have good mouth melting and wateriness, and are mixed with various acidic taste ingredients such as fruit sauce, fruit juice, and yogurt Even so, a variety of flavored oil-in-water creams that can be whipped have been demanded.

Patent Document 1 discloses a polyglycerin fatty acid ester containing 50% by weight or more of a lauric fat and oil in a fat and oil component, an oily phase having a specific SFC value, a protein component and a sugar phase, and a polymerization degree of 4 to 10. Are mixed as an emulsifier, pre-emulsified, homogenized, and sterilized, and a method for producing an oil-in-water emulsified fat having a foaming property with a water activity value of 0.96 or less is disclosed.

Patent Document 2 discloses that the proportion of lauric acid residues in the total fatty acid residues constituting all triglycerides in fats and oils is 30 to 60% by mass, and the fatty acid residues constituting individual triglycerides in the fats and oils The proportion of the triglycerides having a total number of carbon atoms of 42 to 49 is 20 to 45% by mass of the total triglycerides in the fat and oil, and the number of carbon atoms of the fatty acid residues constituting the individual triglycerides in the fat and oil There is disclosed a foamable oil-in-water emulsified fat / oil composition in which the proportion of triglycerides having a total of 50 to 62 is 4 to 15% by mass of the total triglycerides in the oil or fat.

However, in all Examples of Patent Documents 1 and 2, skim milk powder or skim concentrated milk containing casein protein is used as a protein component. When the viscosity is set to 2 to 5, the desired overrun whipped cream cannot be obtained by thickening, solidifying and whipping.

In Patent Document 3, as an oil-in-water emulsion that can be whipped by mixing with an acidic taste material, it is composed of 40 to 80% by weight of an aqueous phase and 20 to 60% by weight of an oil phase, and 0.05 to 10% by weight. % Whey protein, 0.2-5% by weight skim milk solids, and an acid-resistant oil-in-water emulsion containing a total phosphate and citrate weight of less than 0.01% by weight is disclosed. ing. However, since the oil-in-water emulsion has a low sugar content, it does not have a quality that allows it to be distributed at room temperature. Moreover, even if aiming at the quality of normal temperature distribution by reducing the water and fats and oils in the oil-in-water emulsion and adding saccharides, the product can be stably produced by scorching due to heat sterilization during production. There is a problem that you can not.

Patent Document 4 discloses that an oil-in-water emulsion containing water, fats and oils, whey protein, and an emulsifier contains 0.03 to 0.4% by weight of whey protein and does not contain lecithin as an emulsifier. An oil-in-water emulsion having acid resistance and foaming resistance is disclosed, which includes a polyglycerin fatty acid ester whose constituent fatty acid is oleic acid and a sucrose fatty acid ester having an HLB value in the range of 4 to 15. Patent Document 5 discloses fats and oils, protein having a specific mass ratio of casein protein / whey protein, lecithin, a specific average glycerin polymerization degree and a specific HLB polyglycerin saturated fatty acid ester, dietary fiber and / or chemical process. A whipped cream composition containing starch and having a flavor and performance as a normal whipped cream and further having acid resistance and freeze resistance is disclosed. However, since all the examples of Patent Documents 4 and 5 use only hardened palm kernel oil (34 ° C.) or a mixed oil of palm kernel oil and palm kernel hardened oil (8: 2), it is blended with an acidic substance. The whipped cream that has been whipped is harder and easier to tighten with time, and there is a problem that there is a lot of water separation.

The pH of the whipped cream is measured using pH METER (“F-52” manufactured by Horiba, Ltd.).

The overrun of whipped cream is preferably 100% or more, more preferably 130 to 180%. If the overrun is less than 100%, melting in the mouth may be felt, which is not preferable. Note that the whipped cream overrun is the percentage of the air contained in the whipped cream.

For the measurement of overrun, first, the foamable oil-in-water emulsified oil / fat composition and the acidic taste material are mixed to a specific amount, and the resulting mixture is placed in a 100 cm ³ container, Measure. The mixture is whipped until reaching a suitable hardness for topping, and the resulting whipped cream is put into a 100 cm ³ container and the mass is measured. Based on these measured values, the overrun can be obtained by the following equation.

Overrun (%) = [(mass of a mixture of a certain volume of foamable oil-in-water emulsified oil and fat composition and acidic taste ingredients) − (mass of a certain volume of whipped cream)] ÷ (constant volume of whipped Mass of docream) x 100

Casein protein is a protein that precipitates when the pH of milk is adjusted to pH 4.6 at 20 ° C., and refers to four types of proteins, αS1 casein, αS2 casein, β casein, κ casein, and γ casein. For example, protein containing casein protein includes raw milk, milk, special milk, partially skimmed milk, skim milk, processed milk, cream, butter, cheese, ice cream, concentrated milk, skimmed concentrated milk, non-sugared milk, and nothing.

Here, the degree of esterification refers to the number of fatty acid molecules bound to one molecule of polyglycerol. If the degree of esterification is less than 1, it will contain a large amount of non-esterified polyglycerin, resulting in unstable emulsification, or suppression of scorch during heat sterilization during the production of a foamable oil-in-water emulsified oil composition. The effect may be insufficient.

When it exceeds 0.5 mass%, the flavor of a whipped cream may worsen.

The aqueous phase can further contain an emulsifier other than the polyglycerin fatty acid ester of HLB 12 or higher. Examples of the emulsifier include glycerin fatty acid ester, polyglycerin fatty acid ester of less than HLB 12, sucrose fatty acid ester, sorbitan fatty acid ester, propylene glycol fatty acid ester, soybean lecithin, egg yolk lecithin, and fractionated lecithin thereof, and further enzymatic degradation.
