Description

Frozen

Technical field

The utility model relates to field of food, and specifically, the utility model relates to frozens.

Background technique

Frozen includes with drinking water, dairy products, sweetening material, fruit, beans product, edible oil and fat etc. for primary raw material, addition Suitable fragrance, colorant, stabilizer, emulsifier etc. through ingredient, the processes such as sterilize, congeal, pack and manufactured product.Packet Include ice cream, ice cream, slush, ice lolly, edible ice, sweet taste ice etc..

Anthocyanidin (Anthocyanidin) is a kind of water-soluble phytochrome, is present in the cell liquid in vacuole, can With with the soda acid of cell liquid change color, be common in flower, fruit tissue in and cauline leaf epidermal cell and underlying epidermis layer.Its With glucide with glycosidic bond in conjunction with after be anthocyanin, redden etc. with colored color, leaf related, be a kind of natural antioxygen Agent.Color can be changed with the soda acid of cell liquid.Cell liquid is then partially red in acidity, and cell liquid is then partially blue in alkalinity.

Black carrot pigment is the anthocyanin class pigment extracted from black carrot fleshy root, containing a large amount of anthocyanidin and Carrotene.Capable of preventing myopia, alleviation asthenopia, prevention cardiovascular disease, antitumor and anticancer etc..Often eating can also enhance Middle-aged and the old's constitution, prevention and treatment respiratory tract infection, adjust metabolism, and build up one's resistance to disease.It can be applied to food, health care Product, drug, colorant, the multiple fields such as nutrition fortifier.Different colors is shown under the conditions of different pH.

Currently, frozen color in the market is that monochromatic or polychrome combines, color cannot generate change during edible Change, without viewing pleasure.Currently, in the market without the frozen that can produce the third color when eating.

Thus, the frozen that can produce the third color (with very strong viewing pleasure) when preparing a kind of edible still has It is to be developed.

Utility model content

The application is to be made based on inventor to the discovery of following facts and problem and understanding:

Different colors can be presented in acid-base indicator at different pH, and inventor is put forward for the first time frozen as a result, In composition be divided into acidic materials and alkaline matter, and the either suitable acid-base indicator of external source addition (such as anthocyanidin, black Carrotene etc.) still dexterously using acid-base indicator ingredient natural contained in fruit juice, vegetable juice, it can reach The effect of discoloration, based on the discovery of above-mentioned phenomenon, the frozen of changeable colour when inventor develops a kind of edible, freezing drink Product are during edible, gentle agitation, can produce the third color, it can keep frozen real during edible Now change colour.

In the utility model in a first aspect, the utility model proposes a kind of frozens.It is according to the present utility model Embodiment, the frozen are provided at least two spaces of separation, the first space, and first space is provided with first group Point or the second component；Second space, the second space connect with first space, and the second space, which is provided with, to be different from Another component in the first space；Wherein, first component or the second component include acid-base indicator.First in frozen Component and the second component before mixing, at least two spaces of the separation that is placed in, only when mixing in need, the first component and Two components just carry out mixing and then generate the third color.According to the frozen of the utility model embodiment in edible process In, gentle agitation can produce the third color, i.e. frozen is able to achieve discoloration during edible, specific very strong view Feel enjoyment.

Embodiment according to the present utility model, above-mentioned frozen can also further comprise following additional technical feature at least One of:

Embodiment according to the present utility model, first component include acid material, and the second component includes alkalinity material.Invention Frozen is arranged to acid material to people and alkalinity is expected, is suitable for acid, alkaline condition to provide.

Embodiment according to the present utility model, the acid-base indicator are anthocyanidin or black carrotene.Anthocyanidin, black Hu All different colors is presented under the conditions of different pH in radish element.Inventor is put forward for the first time, and soda acid is placed in frozen and is referred to Show the concept of agent.Inventor utilizes These characteristics, is changed colour under conditions of acidity material and alkalinity are expected using acid-base indicator.It needs Illustrate, acid-base indicator can be by the first component or the second component itself offer, be also possible to external source addition.

Embodiment according to the present utility model, the content of the anthocyanidin are 0.05%, the content of the black carrotene It is 0.08%.It should be noted that the percentage of above-mentioned content is acid material where accounting for it or the quality percentage in alkalinity material Than.Inventors have found that adding the anthocyanidin or black carrotene of above-mentioned mass ratio, color change is obvious, is less than above-mentioned mass ratio, The pH value gap of light color and two kinds of acid-base property material of material is small, so color change is unobvious, it is more than above-mentioned mass ratio, color becomes Changing significant degree there will be no variation, and increase production cost.
