摘要
为改善辣条坯体品质,测定添加0%,3%,6%,9%(质量分数,下同)甘露醇、赤藓糖醇、异麦芽酮糖醇、乳糖醇、木糖醇、山梨糖醇、麦芽糖醇对辣条坯水分活度、膨胀率、持油能力和存储0、1、2、3、4周水分含量与质构特性的影响。结果表明,在不同储存周期中,7种糖醇均能有效减少辣条坯水分损失、降低辣条坯硬度,过量添加则会带来负面效果。3%的甘露醇、异麦芽酮糖醇、木糖醇显著提高辣条的膨胀率和持油能力,过量添加则会出现相反效果;随着赤藓糖醇、乳糖醇、山梨糖醇添加量的增加,辣条坯膨胀率和持油能力呈现先降低后上升的趋势;而麦芽糖醇显著降低辣条的膨胀率和持油能力。因此,在辣条生产中添加适量的糖醇能改善产品品质,增加产品收益。
Chinese spicy snack food is a type of extruded product processed from wheat flour or soy products,and the annual loss is huge due to the loss of water,hardening and poor taste.In this study,0%,3%,6%,9%of mannitol,erythritol,isomalt,lactitol,xylitol,sorbitol,maltitol were added to raw materials to improve the quality of Chinese spicy snack food.And it was evaluated by measuring the water activity,radial expansion rate,oil holding capacity of Chinese spicy snack food and the change of moisture,texture after storage for 0,1,2,3 and 4 weeks.The results showed that the seven polyols could effectively reduce the water loss and hardness of Chinese spicy snack food in different storage times.However,excessive addition will bring negative effects to the products.The radial expansion rate and oil holding capacity of Chinese spicy snack food were significantly improved with 3%mannitol,isomalt and xylitol.Excessive addition will also bring negative effects.The radial expansion rate and oil holding capacity of Chinese spicy snack food showed a trend of rising first and falling than with the increase of erythritol,lactitol and sorbitol.And radial expansion rate and oil holding capacity of Chinese spicy snack food was significantly reduced.Therefore,the appropriate addition of polyols can improve product quality and increase product profits in the production of Chinese spicy snack food.
