According to their classification, candies can be divided into hard candies, hard-centered candies, cream-based candies, gel candies, polished candies, gum-based candies, aerated candies, and compressed candies. Among these, hard candies are a type of candy characterized by a hard, crisp texture, with white granulated sugar and starch syrup as the primary ingredients. Hard-centered candies are hard candies that contain a filling inside. Cream-based candies are made primarily from white granulated sugar, starch syrup (or other sweeteners), fats, and dairy products; they contain at least 1.5% protein and at least 3.0% fat, and have a distinctive creamy and roasted aroma. Gel candies are soft-textured candies made mainly from edible gels (or starch), white granulated sugar, and starch syrup (or other sweeteners). Polished candies are candies with a glossy, firm surface.

Gum-based candies are chewable or bubble-forming sweets made primarily from granulated sugar (or sweeteners) and gum base substances. Aerated candies are sweets whose interiors contain fine, evenly distributed air bubbles. Tablet candies are sweets that have been formed through granulation, binding, and compression into a solid tablet shape.

Consumers should pay attention to the following points when selecting candies:

1. You should purchase candies from reputable, large-scale department stores or supermarkets, as these establishments have strict quality controls over the products they stock, use standardized procurement channels, and can guarantee both product quality and after-sales service.

2. Choose products manufactured by large enterprises or established brands—these companies have standardized management practices and consistently stable product quality.

3. Examine the label and packaging. First, check whether the outer packaging is neat and clean, whether the printing on the labels is clear, whether the labels are intact, and whether the product is within its expiration date. Try to choose products that were recently manufactured.

4. Sensory Evaluation: Normally, candies should meet the following criteria: (1) Uniform and consistent color; pure and moderate aroma; normal taste; free from any off-flavors or odors; and possess the characteristic color and fragrance of the product. (2) Free from visible impurities; no bubbling, no deliquescence, and no sticking to the wrapping paper; the packaging paper should be intact, with no signs of tearing or damage. (3) For semi-soft candies containing nuts, peanuts, or similar ingredients: they should show no signs of rancidity, insect infestation, or mold growth. Soft candies should be elastic and free from melting or stickiness.

5. The surface of the chocolate candies is smooth and delicate, with no whitening, mold spots, musty odor, or burnt taste.
